*This document is like a lab demo—an example Certificate of Analysis (COA) that showcases what a COA looks like but may not match the latest batch in all its glory. Think of it as a chemistry experiment: close, but not quite the final reaction!

| hazards summary | Possible skin sensitizer. Dust can be a fire and explosive hazard. Occupational asthma has been reported, but its incidence is very low. Palladium II chloride is a stronger skin sensitizer than nickel sulfate. The metals in this group generally are nontoxic in the metallic state, but the soluble halide salts (particularly of Pt) and osmium tetroxide are highly reactive. Exposure to these elements results in hypersensitivity allergic reactions in susceptible individuals. Tram drivers in Rome were exposed to Pt, Rh and Pd from catalytic converters at levels about 10 times lower than those known to cause adverse effects in workers. See Palladium tetraamine dichloride. |
| toxicity summary | IDENTIFICATION: Palladium is a steel white ductile metallic element. It is stable in air and resistant to attack by most reagents. It is soluble in a mixture of hydrochloric and nitric acids. Palladium and its alloys are used as catalysts in the petrochemical and automotive industries. Used in electronics and in dental applications. Purified metals between 99.9% and 99.99% are available for chemical use as foil, granules, rod or wire. HUMAN EXPOSURE: The general population is primarily exposed to palladium through dental alloys, jewlery, food and emissions from automobile catalytic converters. There are limited data concerning the distribution of palladium from dental resorations in human tissues or fluids. Populations at special risk of palladium allergy include people with known nickel allergy. ANIMAL STUDIES: Six months after a single intratracheal application of palladium dust, several histopathological signs of inflammation were noted in the lungs of rats. Daily oral administration of palladium dust over 6 months resulted in changes in several blood and urine parameters. Palladium applied in its metallic form showed no or little cytotoxicity.[Palladium ions are able to inhibit most major cellular fuctions. They form strong complexes with both inorganic and organic ligands, substitute essential ions, bind to amino acids and various enzymes including creatine kinase and prolyl hydroxylase, and interact with functional groups of other macromolecules such as DNA leading to strand breakage. |
| symptoms | Skin contact with palladium may cause contact dermatitis, erythema, and oedema. |
| health effects | Contact with palladium may cause palladium sensitivity and allergy. Animal studies have shown that palladium may damage the liver and kidney. |
| carcinogen classification | default_key: No indication of carcinogenicity to humans . |
