title: Blood lead content in a peri-urban population of the South American toad Bufo arenarum.
abstract: Blood Pb concentration in a South American toad Bufo arenarum population (n = 152) was determined over 10 samplings carried out between December 1996 and November 1999. The studied population lived in the surroundings of the La Plata City, the largest industrial-urban setting of the Buenos Aires Province, Argentina. The presence of the metal was detected in all the samples tested, the mean concentration range being 1.99-4.66 mg dl(-1). Some preliminary environmental data on soil content of Pb in the sampling area suggest the anthropogenic origin of the metal possibly due to high rate of Pb-containing gasoline utilisation until recently. The reported results may reflect a sequel of a sustained local air-soil-water pollution process.
