Fresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse and then wash skin with water and soap. 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. Give a slurry of activated charcoal in water to drink. Rest. Refer 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: 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. Generally, the induction of vomiting is NOT recommended outside of a physician's care due to the risk of aspirating the chemical into the victim's lungs. However, if the victim is conscious and not convulsing and if medical help is not readily available, consider the risk of inducing vomiting because of the high toxicity of the chemical ingested. Ipecac syrup or salt water may be used in such an emergency. 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. IMMEDIATELY transport the victim to a hospital.
OTHER: Since this chemical is a known or suspected carcinogen you should contact a physician for advice regarding the possible long term health effects and potential recommendation for medical monitoring. Recommendations from the physician will depend upon the specific compound, its chemical, physical and toxicity properties, the exposure level, length of exposure, and the route of exposure. (NTP, 1992)

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit 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.

IDENTIFICATION: Heptachlor is a chlorinated dicyclopentadiene insecticide that is persistent in the environment and accumulates in the food chain. Although its use has been banned or severely restricted in many countries since the 1980's, it is still detected as a contaminant in some food commodities. Heptachlor in its pure form at room temperature appears as a white or light tan crystalline solid with a mild camphor or cedar like odor. The technical product is a soft wax. The technical product usually contains about 72% heptachlor and about 28% related compounds such as trans-chlordane (20-22%) and trans-nonachlor (4-8%). HUMAN EXPOSURE: In humans placental transfer of heptachlor has been noted. Available epidemiological data do not show a clear relationship between adverse health effects and exposure to heptachlor. Consumption of foods containing pesticides such as heptachlor leads to an accumulation of these compounds in human tissues. Heptachlor has been detected in blood and serum samples, adipose tissue and breast milk. The most significant source of exposure of infants to heptachlor and its metabolites appears to be breast milk, in which concentrations can be much higher than those found in dairy milk. Heptachlor induced statistically significant increase in unscheduled DNA synthesis in human fibroblasts in the presence of metabolic activation and heptachlor inhibited junctional intracellular communication in cultured human cells. ANIMAL/PLANT/AVIAN/CRUSTACEAN/FISH/INVERTEBRATES STUDIES: In animals fed heptachlor by diet, gavage or sc injection, there is a sharp dose response curve for mortality. No marked differences were seen between treated animals and controls with respect to body weight and food consumption. Liver enlargement has been noted with accentuated lobulation; histopathological findings showed enlargement of centrilobular and midzonal hepatocytes. Fertility studies in rats injected with heptachlor sc resulted in suppression of reproductive hormone levels, disruptions in female cyclicity and delays in mating behavior. In developmental toxicity studies, there were usually no clinical signs of maternal toxicity (dose related alterations in weight gain) until mortality occurred. In one study reduced litter sizes was noted, postnatal mortality of the pups was the most obvious finding. No teratological effects was noted. The profile of effects produced by repeated heptachlor to female rats consisted of altered activity, hyperexcitability and autonomic effects. Neurotoxicological studies on perinatal heptachlor exposure in the rat suggested developmental delays, alterations in GABAergic neurotransmission and neurobehavioral changes which included cognitive deficits at all doses. Heptachlor and technical grade heptachlor have been tested for carcinogenicity by oral administration in several strains of rats and mice. Technical grade heptachlor was shown to be carcinogenic in male and female mice but not in rats. Heptachlor has been shown to be neurotoxic and immunotoxic in rats. Heptachlor shows mostly negative responses in vitro and in vivo genotoxicity testing. The acute toxicity of heptachlor was tested using a variety of aquatic species from different trophic levels. Heptachlor was shown to be toxic to fish and other species. Heptachlor appears to exhibit moderate toxic effects upon terrestrial vertebrates. Heptachlor has been found in tissues of water birds, amphibians, reptiles, seals and whales. Heptachlor is clearly toxic to a range of both freshwater and marine species, including algae. Growth of both freshwater marine species including algae and shrimp was effected by heptachlor exposure. Heptachlor is moderately toxic to birds.
Heptachlor is a central nervous system stimulant. It non-competitively blocks neurotransmitter action at gamma-amino butyric acid receptors, resulting in overstimulation of the nervous system. Heptachlor is also believed to exert carcinogenic effects by activating key kinases in signalling pathways and inhibiting apoptosis. (L118, A81, A82)

The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in fish and milk. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.
Heptachlor was used extensively as an insecticide on many agricultural crops until its use was banned by EPA in 1974. Its production and former use in termite control, seed/seed furrow treatment, and wood treatment did result in its direct release to the environment. If released to air, a vapor pressure of 4.00X10-4 mm Hg at 25 °C indicates heptachlor will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase heptachlor will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozone; the half-life for these reactions in air are estimated to be 6.3 and 1.4 hours, respectively. Particulate-phase heptachlor will be removed from the atmosphere by wet and dry deposition. Direct and photosensitized photolysis of unabsorbed heptachlor may occur in the environment. Heptachlor at 1.35X10-7 to 1.0X10-5 mole/l in acetone irradiated with light for >180 min at >290 nm degraded by about 5 to 10%. If released to soil, heptachlor is expected to have no mobility based upon a range of Kocs of 13,330 to 661,000. Volatilization from moist soil surfaces is expected to be an important fate process based upon a Henry's Law constant of 2.94X10-4 atm-cu m/mole. Complete degradation of heptachlor in flooded Casiguran sandy loam and Louisiana clay occurred after 1 and 2 months, respectively, and was nearly complete in Maahas clay after 3 months. However, field dissipation half-lives for heptachlor can range from 40 days to 5.5 yrs. If released into water, heptachlor is expected to adsorb to suspended solids and sediment based upon the range of Koc's. In water, 95.3% of heptachlor was removed by an acclimated aerobic mixed microbial culture in 4 weeks. Anaerobic incubation of heptachlor with thick sewage sludge inoculum at 53 °C resulted in complete degradation in about 1 day. Volatilization from water surfaces is expected to be an important fate process based upon this compound's Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 6 hours and 9 days, respectively. However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 1.5 years if adsorption is considered. A range of BCF values of 200 to 37,000 suggest bioconcentration in aquatic organisms is high to very high. In water and moist soil, heptachlor readily undergoes hydrolysis to 1-hydrochlorodene which is then readily converted by microorganisms into heptachlor epoxide. The chemical hydrolysis half-life for heptachlor is 4.5 days at pH 7. Occupational exposure to heptachlor may occur through inhalation of dust particles and dermal contact with this compound at workplaces where heptachlor was produced or used. Monitoring data indicate that the general population may be exposed to heptachlor via inhalation of ambient air (especially indoor air of homes treated with heptachlor), ingestion of food (e.g., fish) and drinking water. (SRC)
Heptachlor's production and former(1) use in termite control, seed/seed furrow treatment, and wood treatment(2) has resulted in its direct release to the environment(SRC). Heptachlor was used extensively as an insecticide on many agricultural crops until its use was banned by EPA in 1974(3).
TERRESTRIAL FATE: Based on a classification scheme(1), Koc values for heptachlor from 13,330-661,000(2), indicates that heptachlor is expected to be immobile in soil(SRC). Volatilization of heptachlor from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 2.94X10-4 atm-cu m/mole(3). However, volatilization from moist soil surfaces is expected to be attenuated by adsorption to soil(SRC). When heptachlor was applied to orchard grass, approximately 90% was lost in 7 days(4). Six hours and 6 days after application of heptachlor to a moist soil surface, 50% and 90% of the heptachlor had volatilized, respectively(5). However, only 7% of heptachlor incorporated 7.5 cm into soil had volatilized after 167 days(5). Fifty hours following the application of heptachlor to a dry soil surface, 14 to 40% of the heptachlor had volatilized(5). In moist soil, heptachlor readily undergoes hydrolysis to 1-hydrochlorodene which is then readily converted by microorganisms into heptachlor epoxide(6). Chemical hydrolysis half-lives for heptachlor are 5.4, 4.3, 4.5, 4.5, and 3.0 days for pH 4.5,5.0, 6.0, 7.0, and 8.0, respectively(7). Heptachlor absorbs light weakly above 290 nm(8) and thin films of heptachlor have been shown to undergo direct photolysis when exposed to sunlight and artificial light sources >290 nm(9). Degradation of heptachlor in flooded Casiguran sandy loam after 1 month and Louisiana clay after 2 months was complete (initial concn about 13 ppm) and nearly complete in Maahas clay after 3 months(10). In Pila clay loam, degradation proceeded to only about 5 ppm from the initial level of about 13 ppm after 3 months(10). Biodegradation of heptachlor by soil microorganisms produced heptachlor epoxide and chlordene(11). Field dissipation half-lives for heptachlor can range from 40 days to 5.5 yrs(2).
AQUATIC FATE: Based on a classification scheme(1), a range of Koc values for heptachlor from 13,330 to 661,000(2), indicates that heptachlor is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 2.94X10-4 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 6 hours and 9 days, respectively(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column(SRC). The estimated volatilization half-life from a model pond is 1.5 years hours if adsorption is considered(5). The volatilization half-life of heptachlor was determined to be 0.73 days from static distilled water and 0.29 days from stirred river water(depth not specified)(6). According to a classification scheme(7), BCF values ranging from 200 to 37,000(8-13), suggests the potential for bioconcentration in aquatic organisms is high to very high(SRC). Heptachlor readily undergoes chemical hydrolysis to 1-hydrochlorodene which is then readily processed by microorganisms into heptachlor epoxide(14). Chemical hydrolysis half-lives for heptachlor are 5.4, 4.3, 4.5, 4.5, and 3.0 days for pH 4.5, 5.0, 6.0, 7.0, and 8.0, respectively(15). When heptachlor was aerobically incubated with acclimated, mixed microbial cultures, an average of 95.3% of the initial heptachlor was removed in 4 weeks(16). The products were chlordene, 1-hydroxy-2,3-epoxychlordene and heptachlor epoxide(17). Anaerobic incubation with thick sewage sludge inoculum at 53 °C resulted in complete degradation of 10 ppm heptachlor in about 1 day(18).
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), heptachlor, which has a vapor pressure of 4.0X10-4 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase heptachlor is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozone(SRC). The half-life for reaction with hydroxyl radicals in air is estimated to be 6.3 hours(SRC), calculated from its rate constant of 6.11X10-11 cu cm/molecule-sec at 25 °C(SRC) determined using a structure estimation method(3). The half-life for reaction with ozone in air is estimated to be 1.4 hour(SRC), calculated from its rate constant of 2.0X10-16 cu cm/molecule-sec at 25 °C(SRC) determined using a structure estimation method(3). Particulate-phase heptachlor may be removed from the air by wet and dry deposition(SRC). Heptachlor absorbs weakly above 290 nm(4) and thin films of heptachlor have been shown to undergo direct photolysis when exposed to sunlight and artificial light sources >290 nm(4).
AEROBIC: Mixed cultures of Pseudomonas sp. in water were capable of growing on heptachlor(1). The products were chlordene, 1-hydroxy-2,3-epoxychlordene and heptachlor epoxide(1). When heptachlor was aerobically incubated with acclimated, mixed microbial cultures, 95.3% of the initial heptachlor was removed in 4 weeks(2); biodegradation of 1 mg/l heptachlor occurred immediately(2). The products resulting from the incubation of heptachlor with a mixed culture of soil microorganisms were chlordene(7%), 1-exohydroxychlordene, heptachlor epoxide (<0.04%) and chlordene epoxide (<0.02%) which were formed after 2 weeks(3). Biodegradation of heptachlor by soil microorganisms produced heptachlor epoxide and chlordene(4). Degradation of heptachlor in flooded Casiguran sandy loam after 1 month and Louisiana clay after 2 months was complete (initial level about 13 ppm) and nearly complete in Maahas clay after 3 months(5). In Pila clay loam, degradation proceeded to only about 5 ppm from the initial level of about 13 ppm (approx 38%) after 3 months(5).
ANAEROBIC: Anaerobic incubation of 10 ppm heptachlor with a thick anaerobically digested sewage sludge inoculum at 53 °C resulted in complete degradation in about 1 day(1); at 35 °C with the thick sludge, heptachlor was converted to an extractable degradation product which was more persistent than heptachlor(1).
The rate constant for the vapor-phase reaction of heptachlor with photochemically-produced hydroxyl radicals and ozone has been estimated as 6.11X10-11 cu cm/molecule-sec and 2.00X10-16 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 6.3 hrs and 1.4 hrs at an atmospheric concn of 5X10+5 hydroxyl radicals per cu cm and 7X10+11 ozone molecules per cu cm, respectively(1). In water, heptachlor readily undergoes chemical hydrolysis to 1-hydrochlorodene which is then readily converted by microorganisms into heptachlor epoxide(2). Chemical hydrolysis half-lives for heptachlor are 5.4, 4.3, 4.5, 4.5, and 3.0 days for pH 4.5,5.0, 6.0, 7.0, and 8.0, respectively(3). Heptachlor absorbs weakly above 290 nm(4) and thin films of heptachlor have been shown to undergo direct photolysis when exposed to sunlight and artificial light sources >290 nm(5). The products were two dechlorinated photoproducts and heptachlor epoxide(5). Heptachlor at 1.35X10-7 mol/l to 1.0X10-5 mol/l in acetone irradiated for >180 min at >290 nm degraded by about 5 to 10%(6). Photoheptachlor was the photoproduct(6). Heptachlor also undergoes photosensitized photolysis in the presence of benzophenone(5). Photolysis of heptachlor can take place on plant leaves in the presence of sunlight or UV light(7). Thus, direct and photosensitized photolysis of unabsorbed heptachlor may occur in the environment(SRC).
BCF values for several fish, molluscs, and other aquatic species range from 200 to 37,000 for heptachlor(1-6). According to a classification scheme(7), these BCF values suggest that bioconcentration in aquatic organisms ranges from high to very high(SRC). Bioaccumulation factors (BAFs) for heptachlor have been measured for aquatic molluscs (250 to 2,500), oysters (17,600), pelecypod (3,900 to 8,500), decapod (200 to 700), Cyprinodon variegatus (7,400 to 21,300), Lagodon rhomboides (2,800 to 7,700), Leiostomus xanthurus (3,000 to 13,800), Cyprinodon variegatus (3,700 to 4,600), trout(300), and fathead minnow(6,310 to 20,000)(2). BCFs of heptachlor are 3,800 in mosquito fish(3); 3,600 to 7,400 in spot(3); 21,379 in sheepshead minnows(4); 37,000 in snails(3); 21,000 in alga(3); 18,000 in oysters(6); and 17,400 in unidentified fish species(5). At Mar Meno Lagoon (SE Spain), the BCF of heptachlor was measured in plant and aquatic organisms(8): algae (470), red algae (3,220), bivalve mollusc (1,770), and isopods (56,030). The bioaccumulation (ie, concn in biota/concn in soil) of heptachlor by earthworms ranges from 0.92 to 2.7(9). The BCF of heptachlor in vegetation is 0.033(2). Biomagnification of heptachlor in the aquatic food chain is significant, however because it is readily metabolized to heptachlor epoxide by higher tropic level organisms, biomagnification of heptachlor itself is not significant(10).
The Koc values for heptachlor range from 13,330 to 661,000(1,2). According to a classification scheme(3), these Koc values suggest that heptachlor is expected to be immobile in soil(SRC). Heptachlor was added to soil columns containing Hagerstown silty clay loam and Lakeland sandy loam which were then subjected to the upward movement of water at an undisclosed rate(3). After 3 days, all the heptachlor was detected in the initial column depth, indicating no tendency to leach in these soils(4).
The Henry's Law constant for heptachlor is 2.94X10-4 atm-cu m/mole(1). This Henry's Law constant indicates that heptachlor is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 6 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 9 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column(SRC). The estimated volatilization half-life from a model pond is 1.5 years if adsorption is considered(3). The volatilization half-life of heptachlor from glass surfaces was determined to be 0.73 days from static distilled water and 0.29 days from stirred river water(4). Heptachlor's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). When heptachlor was applied to orchard grass, approximately 90% was lost in 7 days(5). Six hours and 6 days after application of heptachlor to a moist soil surface, 50% and 90% of the heptachlor had volatilized, respectively(6). However, only 7% of heptachlor incorporated 7.5 cm into soil had volatilized after 167 days(6). Fifty hours following the application of heptachlor to a dry soil surface, 14 to 40% of the heptachlor had volatilized(6).

Heptachlor was listed as a contaminant of the Great Lakes including Lakes Ontario, Erie, Huron, Michigan and Superior(3). In 1980, heptachlor was detected in the waters of Lake Pontchartrain Inner Harbor Navigation Canal at a concn of 0.6 ng/l at an ebb tide of 1.5 m and at concns ranging from 9.1 to 9.3 ng/l at flood tides of 1.5 to 10 m(4).

Heptachlor was detected at two locations in the Shatt al-Arab river (Iraq) at mean concns of 10 ng/l (range, 2 to 19 ng/l) and 79 ng/l (range, 50 to 91 ng/l), respectively(9). Heptachlor was detected in the Tigris and Euphrates rivers (Iraq) at mean concns of 19 ng/l (range, 10 to 39 ng/l) and 4 ng/l (range, not detected to 7 ng/l), respectively(9).
SURFACE WATER: The concn of heptachlor in water samples from River Nile (Cairo, Egypt) ranged from 2.4 to 3.5 ng/l and 5.9 to 10.3 ng/l in the winter and summer of 1991, respectively(1). The concn of heptachlor in water samples from Manzala Lake (Egypt) ranged from 6.0 to 15.6 ng/l and 6.5 to 30.0 ng/l in the winter and summer of 1991, respectively(1).
GROUNDWATER: The mean and range of concns of total heptachlor (both suspended and dissolved) in ground water was 0.12 ug/l and 0.09 to 0.15 ug/l, respectively(1). According to the EPA's Pesticides in Groundwater Database, heptachlor was detected in the groundwater supplies of the states of Kansas, Illinois, and Massachusetts at mean concns of 0.03, 0.19, and 0.05 ppb, respectively(2). In New Jersey, the max concn of heptachlor in groundwater was 1.0 ppb (21.2% of 1,075 samples)(3). In a statewide survey (Dec 1985 to Feb 1986) conducted in Kansas, heptachlor was detected in 1% of farm wells at an avg concn of 0.025 ppb (range, 0.023 to 0.026 ppb)(4).
RAIN/SNOW: Heptachlor was detected in wet precipitation samples (rain/snow) from Lake Erie at a volume-weighted mean concn (based on total volume collected over a 12-month period) of 0.1 ng/l(1). Rain water samples were collected in Dec 1995 and Apr 1996 in Egypt where chlorinated hydrocarbon pesticides have been used for over two decades(2); the concn of heptachlor residues in these samples were 3.4 ug/l and 3.1 ug/l, respectively(2).
Of the 671 stations reporting heptachlor in industrial effluents in EPA's STORET database, 3.0% contained detectable levels of this chemical with a median concn of <0.007 ug/l(1).

In New York City from 1989 to 1993, heptachlor was detected in municipal water treatment facilities influent and effluent at concns ranging from 0.021 to 0.35 ug/l and 0.02 to 0.447 ug/l, respectively(5).
Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste numbers P059; D031, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.
