Homogeneous transition metal compounds are inorganic compounds containing only metal atoms,with the largest atom being a transition metal atom. Palladium can be found in a number of food items such as parsnip, potato, cucumber, and green zucchini, which makes palladium a potential biomarker for the consumption of these food products. Palladium can be found primarily in blood, cerebrospinal fluid (CSF), saliva, and urine. Palladium is a non-carcinogenic (not listed by IARC) potentially toxic compound. More than half the supply of palladium and its congener platinum is used in catalytic converters, which convert as much as 90% of the harmful gases in automobile exhaust (hydrocarbons, carbon monoxide, and nitrogen dioxide) into less noxious substances (nitrogen, carbon dioxide and water vapor). Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment, and jewelry. Palladium is a key component of fuel cells, which react hydrogen with oxygen to produce electricity, heat, and water . Palladium may be absorbed through oral, dermal, and inhalation exposure. Once in the body it distributes to the kidney, liver, spleen, lymph nodes, adrenal gland, lung and bone. Palladium and its metabolites are excreted in the urine and faeces (A21) (T3DB).
