Metals -> Metals, Inorganic Compounds

Due to their ability to form strong complexes with both inorganic and organic ligands, palladium ions can disturb cellular equilibria, replace other essential ions, and interact with functional groups of macromolecules, such as proteins or DNA. Palladium complexes binding to DNA and RNA leads to strand breakage. Palladium ions are able to inhibit most major cellular functions, including DNA and RNA synthesis. Palladium compounds have been shown to bind to and inhibit various enzymes, including creatine kinase and prolyl hydroxylase. Nitrate's toxicity is a result of it's conversion to nitrite once in the body. Nitrite causes the autocatalytic oxidation of oxyhemoglobin to hydrogen peroxide and methemoglobin. This elevation of methemoglobin levels is a condition known as methemoglobinemia, and is characterized by tissue hypoxia, as methemoglobin cannot bind oxygen. (A2450, L1613, L798)

Ingested nitrate or nitrite under conditions that result in endogenous nitrosation is probably carcinogenic to humans (Group 2A). (L135)

Contact with palladium may cause palladium sensitivity and allergy. Animal studies have shown that palladium may damage the liver and kidney. Nitrate and nitrite poisoning causes methemoglobinemia. Nitrites may cause pregnancy complications and developmental effects. They may also be carcinogenic. (L1137, L798)

Oral (L1137) ; inhalation (L1137)

Skin contact with palladium may cause contact dermatitis, erythema, and oedema. Nitrate and nitrite poisoning causes methemoglobinemia. Symptoms include cyanosis, cardiac dysrhythmias and circulatory failure, and progressive central nervous system (CNS) effects. CNS effects can range from mild dizziness and lethargy to coma and convulsions. (L1137, L798)

Methemoglobinemia can be treated with supplemental oxygen and methylene blue 1% solution administered intravenously slowly over five minutes followed by IV flush with normal saline. Methylene blue restores the iron in hemoglobin to its normal (reduced) oxygen-carrying state. (L1613)
