Health Effects of Palladium
Palladium is regarded as of low toxicity, being poorly adsorbed by the body when ingested. It may cause skin, eye or respiratory tract irritation, may cause skin sensitization.
Liquid may cause burns to skin and eyes. If swallowed, do not induce vomiting, if conscious give water, milk... In case of contact, flush eyes or skin with plenty of water. Palladium compounds are encountered relatively rarely by most people. All palladium compounds should be regarded as highly toxic and as carcinogenic. Palladium chloride is toxic, harmful if swallowed, inhaled or absorbed through the skin. It causes bone marrow, liver and kidney damage in laboratory animals. Irritant. However palladium chloride was formerly prescribed as a treatment for tuberculosis at the rate of 0.065 g per day (approximately 1 mg kg-1) without too many bad side effects. Do not allow material to be released to the environment without proper environmental permits. Palladium has little environmental impact. It is present at low levels in some soils, and the leaves of trees have been found to containg 0.4 ppm. Some plants, such as the water hyacinth, are killed by low levels of palladium salts but most plants tolerate it, although tests indicate that their growth is affected at levels above 3 ppm. |
