The tropical flood plain Pantanal is one of the world's largest wetlands and a wildlife sanctuary. Mercury (Hg) emissions from some upstream gold mining areas and recent findings of high natural Hg levels in tropical oxisols motivated studies on the Hg cycle in the Pantanal. A survey was made on total Hg in the most consumed piscivorous fish species from rivers and floodplain lakes in the north (Caceres and Barao de Melgaco) and in the south part of Alto Pantanal (around the confluence of the Cuiaba and Paraguai rivers). Samples were collected in both the rainy and dry seasons (March and August 1998) and included piranha (Serrasalmus spp.), and catfish (Pseudoplatystoma coruscans, pintado, and Pseudoplatystoma fasciatum, cachara or surubim). There was only a small spatial variation in Hg concentration of the 185 analyzed fish samples form the 200 x 200 km large investigation area, and 90% contained total Hg concentration below the safety limit for regular fish consumption (500 ng g -1). Concentration above this limit was found in both Pseudoplastystoma and Serrasalmus samples from the Baia Sia Mariana, the only acid soft-water lake included in this study, during both the rainy and dry seasons. Concentration above this limit was also found in fish outside Baia Sia Mariana during the dry season, especially in Rio Cuiaba in the region of Barao de Melgaco. The seasonal effect may be connected with decreasing water volumes and changing habitat during the dry season. The results indicate that fertile women should restrict their consumption of piscivorous fishes from the Rio Cuiaba basin during the dry season. Measures should be implanted to avoid a further deterioration of fish Hg levels. MenosThe tropical flood plain Pantanal is one of the world's largest wetlands and a wildlife sanctuary.
