Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.

INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.

INGESTION: DO NOT INDUCE VOMITING. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and, in addition, have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. Transport the victim IMMEDIATELY to a hospital. (NTP, 1992)

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

Immediate precautionary measure

· Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

· For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.

· For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary.

· If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.

Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.

Wastewater containing acrylic monomers is treated by neutralization and polymerization using hydrogen peroxide as a catalyst. Thus, propylene oxidn wastewater containing 2.75% acrylic acid and 45.1 g chemical oxygen demand/L was heated to 90 degree C, and a 70% aq soln of hydrogen peroxide (hydrogen peroxide - acrylic acid ratio 1:4) was added. After stirring 3 hr, powdered lime was added to pH 8.75. The precipitate was filtered out, and the treated effluent contained 16.2 g chemical oxygen demand/L, a reduction of 64%.

Sizing agents in wastewater are eliminated by either chemical and physical, or biological treatment. Polyacrylates ... in wastewaters are treated by coagulation-flocculation with removal rates of 83.8. ... Natural products, such as maize starch and polyvinyl alcohol (PVA) treated through activated sludge show chemical oxygen demand removal rates > 80 and 42%; biological oxygen demand removal rates > 92.7 and 46.0%, respectively.

Photosensitive waste soln containing poly(vinyl alcohol), acrylic acid monomer and polymer, polyoxyalkylene glycol acrylate resing and a surfactant was treated with potassium persulfate, irradiated, and filtered. The filtrate was flocculated with alum and the sulfate ion SO4(2-) precipitated by barium carbonate and calcium hydroxide.

ACCIDENTAL RELEASE MEASURES; Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Methods and materials for containment and cleaning up: Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations.

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number U008, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.

Burn in approved incinerator. Recommendable methods: Incineration. Not recommendable methods: Landfill and evaporation. Peer-review: Small amounts: Dissolve in large amounts of water and wash down sewer. (Peer-review conclusions of an IRPTC expert consultation (May 1985))

Acrylic acid is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration.

For more Disposal Methods (Complete) data for Acrylic acid (8 total), please visit the HSDB record page.

SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

SRP: Contaminated protective clothing should be segregated in a manner such that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. The completeness of the cleaning procedures should be considered before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at the end of shift, but should remain at employee's place of work for cleaning.

The worker should immediately wash the skin when it becomes contaminated.

Fireproof. Separated from strong oxidants, strong bases, strong acids and food and feedstuffs. Keep in the dark. Store only if stabilized. Store in an area without drain or sewer access. Storage conditions may vary according to the type of inhibitor used. Refer to the manufacturer's instructions for proper storage conditions.

Acrylic acid should be stored in a detached, cool, well-ventilated, non-combustible place, and its containers should be protected against physical damage. Acrylic acid can be stored only in vessels lined with glass, stainless steel, aluminum, or polyethylene. In order to inhibit polymerization during transport and storage, 200 ppm MeHQ (the monomethyl ether of hydroquinone) is commonly added to acrylic acid by the manufacturer. The presence of oxygen is required for the inhibitor to be effective. A major concern during the storage of acrylic acid is the avoidance of elevated temperatures as well as freezing, since both can lead to a failure of the inhibitor system. Ideally acrylic acid should be stored within a temperature range of 15 to 25 °C.

Separate from oxidizing materials, peroxides, initiators, acids, and alkalies. Store in cool, dry, well-ventilated location. Outside or detached storage is preferred.

The effectiveness of phenolic inhibitors is dependent on the presence of oxygen and the monomers must be stored under air rather than an inert atmosphere. Temp must be kept low to minimize formation of peroxides and other products. ... Acrylic acid has a relatively high freezing point (13 °C) and the inhibitor may not be distributed uniformly between phases when frozen acid is partially thawed. ... Provisions should be made to maintain the acid liquid. High temp should be avoided because of dimer formation. ... Glacial acrylic acid should be stored at 16-29 °C to maintain high quality. ... Acrylic acid ... can be stored only in glass, stainless steel, aluminum, or polyethylene-lined equipment.

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Hygroscopic. Storage class (TRGS 510): Flammable liquids

· Wear positive pressure self-contained breathing apparatus (SCBA).

· Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE.

· Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.

ACRYLIC ACID may polymerize violently especially when the frozen acid is partially thawed (freezing point 12 °C or 53 °F). Frozen acid should be melted at room temperature and the process should be well stirred. Do not use heat during the melting process [Kirk-Othmer, 3rd ed., Vol. 1, 1978, p. 330]. Corrodes iron and steel and polymerization may occur on contact with iron salts. The uninhibited acid polymerizes exothermically at ambient temperature and explodes if confined. The inhibitor (usually hydroquinone) greatly reduces the tendency to polymerize. Explosive polymerization can also occur with strong bases, amines, ammonia, oleum, chlorosulfonic acid, and peroxides. Mixing with 2-aminoethanol, 28% ammonium hydroxide, ethylenediamine or ethyleneimine in a closed container causes an increase in temperature and pressure. Can react violently with oxidizing reagents and strong bases [Bretherick, 5th ed., 1995, p. 419].

React readily with electrophilic, free-radical, and nucleophilic agent

Acrylic acid is a strong corrosive agent to many metals, such as unalloyed steel, copper, and brass. Frequently the hydrolysis of such metallic materials generates a deep discoloration in acrylic acid. Polyvalent metal salts formed during hydrolytic reactions could also induce polymerization.

Acrylic Acid

C: Compounds that autopolymerize due to peroxide formation if inhibitors are depleated or not present

IDENTIFICATION AND USE: Acrylic acid is a volatile colorless liquid. It is used in the manufacture of plastics, molding powder for signs, construction units, decorative emblems and insignias, polymer solutions for coatings applications, emulsion polymers, paints formulations, leather finishing, and paper coatings; also used in medicine and dentistry for dental plates, artificial teeth, and orthopedic cement. Commercial glacial acrylic acid contains polymer formation inhibitor hydroquinone monomethyl ether (200 ppm). HUMAN STUDIES: Regardless of the route of exposure, acrylic acid is rapidly absorbed and metabolized. Owing to its rapid metabolism and elimination, the half-life of acrylic acid is short (minutes) and therefore it has no potential for bioaccumulation. The substance is corrosive to the eyes, skin and respiratory tract, and also upon ingestion. Inhalation of the substance may cause lung edema. The symptoms of lung edema often do not become manifest until a few hours have passed, and they are aggravated by physical effort. ANIMAL STUDIES: Although a wide range of LD50 values has been reported, most data indicate that acrylic acid is of low to moderate acute toxicity by the oral route and moderate acute toxicity by the inhalation or dermal route. Acrylic acid is corrosive or irritating to skin and eyes, and is a strong irritant to the respiratory tract. Skin sensitization have been reported. Available reproduction studies indicate that acrylic acid is not teratogenic and has no effect on reproduction. Both positive and negative results have been obtained in in vitro genotoxicity tests. No experimental data relevant to the carcinogenicity of acrylic acid were available. ECOTOXICITY STUDIES: The toxicity of acrylic acid to bacteria and soil microorganisms is low. Algae are the most sensitive group of aquatic organisms. Acrylic acid reduces or eliminates bacterial populations in penguins receiving dietary exposure.

The purpose of this work was to investigate the relationship between the feed composition of 2-hydroxyethyl methacrylate (HEMA)/acrylic acid (AAc) and hydrogel material compatibility towards ocular anterior segment tissues, particularly the corneal endothelium. The monomer solutions of HEMA and AAc were mixed at varying volume ratios of 92:0, 87:5, 82:10, 77:15, and 72:20, and were subjected to UV irradiation. Then, the 7-mm-diameter membrane implants made from photopolymerized materials were placed into the ocular anterior chamber for 4 days and assessed by biomicroscopic examinations, corneal thickness measurements, and quantitative real-time reverse transcription polymerase chain reaction analyses. The poly(HEMA-co-AAc) implants prepared from the solution mixture containing 0-10 vol.% AAc displayed good biocompatibility. However, with increasing volume ratio of AAc and HEMA from 15:77 to 20:72, the enhanced inflammatory response, decreased endothelial cell density, and increased ocular score and corneal thickness were observed, probably due to the influence of surface charge of copolymer membranes. On the other hand, the ionic pump function of corneal endothelium exposed to photopolymerized membranes was examined by analyzing the Na(+),K(+)-ATPase alpha 1 subunit (ATP1A1) expression level. The presence of the implants having higher amount of AAc incorporated in the copolymers (i.e., 15.1 to 24.7umol) and zeta potential (i.e., -38.6 to -56.5mV) may lead to abnormal transmembrane transport. It is concluded that the chemical composition of HEMA/AAc has an important influence on the corneal tissue responses to polymeric biomaterials.

... Male Sprague-Dawley rats /were dosed/ orally in quadruplicate with 4, 40, 400, and 1000 mg/kg acrylic acid or 2, 20, 100, or 200 mg/kg ethyl acrylate in 0.5% methylcellulose at a volume of 5 mL/kg with and without pretreatment with the carboxylesterase inhibitor tri-o-cresyl phosphate [TOCP]. Control animals were given 2 mL/kg corn oil with and without pretreatment. The animals were killed 1 hour after dosing. A "pronounced increase" in glandular and nonglandular stomach weights, edema, and hemorrhage were observed with > 40 mg/kg acrylic acid. Acrylic acid, > 4 mg/kg, significantly depleted nonprotein sulfhydryl [NPSH] content in the glandular stomach, but no significant effect on NPSH in the blood or liver was observed. Pretreatment with TOCP did not have a significant effect on stomach weight or NPSH content. With ethyl acrylate, a significant increase in forestomach weight was observed with the 200-mg/kg dose; no significant change in glandular stomach weight was observed. Treatment with TOCP enhanced the increase in forestomach weight. A linear depletion of NPSH content of the forestomach and glandular stomach was observed 1 hour after dosing with 2 and 20 mg/kg; NPSH content did not change with doses of 100 or 200 mg/kg. No significant dose-dependent effect of ethyl acrylate on NPSH concentration in the blood and liver was seen. Pretreatment with TOCP did not affect the depletion of NPSH content in the glandular stomach or forestomach; however, 100 and 200 mg/kg ethyl acrylate did induce a significant depletion of hepatic NPSH concentration.

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Organic acids and related compounds/

The substance is harmful to aquatic organisms.

Acrylic acid's production and use in the manufacture of plastics, paint formulations, leather finishes, paper coatings, and in medicine and dentistry for dental plates, artificial teeth, and orthopedic cement may result in its release to the environment through various waste streams. Acrylic acid has also been identified in 9 species of Chlorophyceae algae, 10 species of Rhodophyceae algae and in the rumen fluid of sheep. If released to air, a vapor pressure of 3.97 mm Hg at 25 °C indicates acrylic acid will exist solely as a vapor in the atmosphere. Vapor-phase acrylic acid will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozone; the half-lives for these reactions in air are estimated to be 40 hours and 18 days, respectively. Experimental photodegradation rates in distilled water, river water, artificial seawater, and seawater of 2.1X10-4, 5.7X10-4, 4.2X10-4, and 3.9X10-4/sec, corresponding to half-lives of 55, 20, 28, and 30 minutes, respectively. If released to soil, acrylic acid is expected to have very high to high mobility based upon Koc values of 6-137. The pKa of acrylic acid is 4.25, indicating that this compound will exist almost entirely in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil is not expected because the acid exists as an anion and anions do not volatilize. Acrylic acid may volatilize from dry soil surfaces based upon its vapor pressure. Utilizing the Japanese MITI test, 67.8% of the theoretical BOD was reached in 2 weeks indicating that biodegradation may be an important environmental fate process. In a 42 day anaerobic screening study using a sewage seed inoculum, 71% of acrylic acid was mineralized. If released into water, acrylic acid is not expected to adsorb to suspended solids and sediment based upon the Koc values. The pKa indicates acrylic acid will exist almost entirely in the anion form at pH values of 5 to 9, and, therefore, volatilization from water surfaces is not expected to be an important fate process. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Acrylic acid was determined to be stable to hydrolysis at pH 3, 7, and 11. Occupational exposure to acrylic acid may occur through inhalation and dermal contact with this compound at workplaces where acrylic acid is produced or used. Use data indicate that the general population may be exposed to acrylic acid via smoking cigarettes, dermal contact with resin, dental products which may contain small amounts of acrylic acid, and use of consumer products such as floor polish.

Produced by marine algae such as Phaeocystis and Polysiphonia lanosa as a result of hydrolysis of dimethyl-beta-propiothetin.

Acrylic acid's production and use in the manufacture of plastics(1,2), molding powder for signs, construction units, decorative emblems and insignias, polymer solutions for coating applications, emulsion powders, paint formulations, leather finishings, paper coatings, and in medicine and dentistry for dental plates, artificial teeth, and orthopedic cement(2) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), Koc values of 6-137(2) indicate that acrylic acid is expected to have very high to high mobility in soil(SRC). The pKa of acrylic acid is 4.25(3), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization from moist soil is not expected because the acid exists as an anion and anions do not volatilize. Acrylic acid may volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 3.97 mm Hg(5). Utilizing the Japanese MITI test, 67.8% of the theoretical BOD was reached in 2 weeks(6) indicating that biodegradation may be an important environmental fate process in soil(SRC). In a 42 day anaerobic screening study using a sewage seed inoculum, 71% of acrylic acid was mineralized(7).

AQUATIC FATE: Based on a classification scheme(1), Koc values of 6-137(2) indicate that acrylic acid is not expected to adsorb to suspended solids and sediment(SRC). A pKa of 4.25(3) indicates acrylic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(4). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow of 0.35(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Acrylic acid was determined to be stable to hydrolysis at pH 3, 7, and 11(8). Acrylic acid has experimental aquatic photochemical degradation rates of 2.1X10-4, 5.7X10-4, 4.2X10-4, and 3.9X10-4/sec in distilled water, river water, artificial seawater, and seawater, respectively(9), corresponding to half-lives of 55, 20, and 30 minutes, respectively(SRC). Utilizing the Japanese MITI test, 67.8% of the theoretical BOD was reached in 2 weeks(10) indicating that biodegradation may be an important environmental fate process in water(SRC). In a 42 day anaerobic screening study using a sewage seed inoculum, 71% of acrylic acid was mineralized(11).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), acrylic acid, which has a vapor pressure of 3.97 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase acrylic acid is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 40 hours(SRC), calculated from its rate constant of 1.75X10-11 cu cm/molecule-sec at 25 °C(3). Vapor-phase acrylic acid is also degraded in the atmosphere by reaction with ozone(SRC); the half-life for this reaction in air is estimated to be 18 days(SRC), calculated from its rate constant of 6.5X10-19 cu cm/molecule-sec at 25 °C(4). Experimental photodegradation rates in distilled water, river water, artificial seawater, and seawater of 2.1X10-4, 5.7X10-4, 4.2X10-4, and 3.9X10-4/sec(5) corresponding to half-lives of 55, 20, 28, and 30 minutes, respectively(SRC).

AEROBIC: Acrylic acid, present at 100 mg/L, reached 67.8% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). The BOD5/COD ratio for acrylic acid was determined to be 0.22, which is indicative of significant potential for biodegradability(2). A microbial degradation study of acrylic acid in soil indicated that acrylic acid, formed from hydrolysis of acrylamide added to soil, was totally degraded within 15 days of its formation(3).

ANAEROBIC: In a 42 day anaerobic screening study using a sewage seed inoculum, 71% of acrylic acid was mineralized; after acclimation, 81% was degraded to carbon dioxide in 22 days(1). In another study, acrylic acid was toxic to unacclimated anaerobic acetate-enriched cultures; it was poorly utilized (21%) in a completely mixed anaerobic reactor with a 20 day hydraulic retention time and a 90 day acclimation period(1). A possible resolution between the conflicting results for anaerobic degradation is the observation that acetate cultures have to exhaust the acetic acid as a carbon and energy source before utilizing a cross-fed compound(1). Acrylic acid is amenable to anaerobic treatment(2) and in an anaerobic screening study utilizing 10% sludge from a secondary digester as an inoculum, acrylic acid was judged to be degradable with >75% of theoretical methane being produced in 8 weeks of incubation(3). Acrylic acid was degraded in acidogenic systems leading to formation of both acetate and propionate; it was observed that although acrylic acid can be efficiently removed anaerobically, accumulation of volatile acids, particularly propionate, can lead to process failures(4).

The rate constant for the vapor-phase reaction of acrylic acid with photochemically-produced hydroxyl radicals is 1.75X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 40 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(2). The rate constant for the vapor-phase reaction of acrylic with ozone has been measured as 6.5X10-19 cu cm/molecule-sec at 25 °C(3). This corresponds to an atmospheric half-life of about 18 days at an atmospheric concentration of 7X10+11 molecules/cu cm(4). The rate constant for the aqueous-phase reaction with photochemically-produced hydroxyl radicals has been determined to be 1.5X10+9 L/mol-sec at pH 1(5). This corresponds to an aqueous half-life of approximately 1.5 years at an aqueous hydroxyl radical concentration of 1.0X10-17 mol/L(5). Acrylic acid was determined to be stable to hydrolysis at pH 3, 7, and 11(6). Acrylic acid has experimental aquatic photochemical degradation rates 2.1X10-4, 5.7X10-4, 4.2X10-4, and 3.9X10-4/sec in distilled water, river water, artificial seawater, and seawater, respectively(7), corresponding to half-lives of 55, 20, 28, and 30 minutes, respectively(SRC).

An estimated BCF of 3 was calculated in fish for acrylic acid(SRC), using a log Kow of 0.35(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Koc values for acrylic acid have been reported as 6 in Washington clay/loam (29% sand, 42% silt, 29% clay, 3.39% organic carbon, pH 6.0), 9 in Canfield loam (45% sand, 42% silt, 13% clay, 4.58% organic carbon, pH 6.1), 29 in Ellsworth loam (35% sand, 40% silt, 25% clay, 1.42% organic carbon, pH 7.2), 137 in Tyner loamy sand (79% sand, 14% silt, 7% clay, 0.46% organic carbon, pH 5.2), and 33 in sandy loam sediment (53% sand, 28% silt, 19% clay, 1.23% organic carbon, pH 7.5)(1) According to a classification scheme(2), these Koc values suggest that acrylic acid is expected to have very high to high mobility in soil. The pKa of acrylic acid is 4.25(3), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).

The pKa of 4.25(1) indicates acrylic acid will exist almost entirely in the anion form at pH values of 5 to 9, and, therefore, volatilization from water surfaces and moist soil is not expected to be an important fate process(2). The potential for volatilization of acrylic acid from dry soil surfaces may exist(SRC) based upon a vapor pressure of 3.97 mm Hg(3).

Acrylic acid was identified as a component of the emissions from polyethylene, ethylene-vinyl acetate, and ethylene-methyl acrylate resins, at a concentration of 0.02 ug/g(1).
