Total arsenic (As) contents were determined in 540 muscle tissue samples of Baltic fishes (herring, sprat, cod, and flounder) caught in 2001-03. Effects of fish size and fishing ground location (Eastern, Central, and Southern Baltic) on As accumulation by the muscle tissue were explored, using flounder as a model. The maximum acceptable As content in fish and fish products in 2003 was 4.0 mg/kg wet weight (w.w.). In none of the samples was this level exceeded. The highest mean As contents (0.78 mg/kg w.w.) were typical of sprat, the lowest (0.26 mg/kg w.w.) being recorded in flounder. The species studied differed significantly (p less or equal 0.05) in their muscle tissue As contents, except for cod and flounder that showed no significant interspecific differences (p greater or equal 0.05). The Eastern Baltic flounder showed significantly (p less or equal 0.05) higher As contents than their conspecifics harvested in both the Central and the Western Baltic. The As contents in the 30-40 cm long flounder were significantly (p less or equal 0.05) higher than those recorded in smaller fish, i.e., those measuring 20-30 cm and those smaller than 20 cm
