✦ Synopsis

Three mushroom species from two old arsenic smelter sites in Austria were analyzed for arsenic compounds. The total arsenic concentrations were determined by ICP-MS. Collybia maculata contained 30.0 mg, Collybia butyracea 10.9 mg and Amanita muscaria 21.9 mg As kg Ϫ 1 dry mass. The arsenic compounds extracted with methanol/water (9:1) from the dried mushroom powders were separated by HPLC on anion-exchange and reversed-phase columns and detected by ICP-MS using a hydraulic high-pressure nebulizer. In Collybia maculata almost all arsenic is present as arsenobetaine. Collybia butyracea contained mainly arsenobetaine (8.8 mg As kg Ϫ 1 dry mass) and dimethylarsinic acid (1.9 mg As kg Ϫ 1 ). Amanita muscaria contained arsenobetaine (15.1 mg As kg Ϫ 1 ), traces of arsenite, dimethylarsinic acid and arsenate, and surprisingly arsenocholine (2.6 mg As kg Ϫ 1 ) and a tetramethylarsonium salt (0.8 mg As kg Ϫ 1 ).
