Resumen:
In this paper, the geographic distribution of arsenic and other trace elements in surface waters of 39 lotic ecosystems of central Argentina was evaluated. Manganese and arsenic were the most conspicuous elements, being present in 82%and 59%of the sampled ecosystems of this region, respectively. As concentration averaged 113.69 lg L-1 varying between 55 and 198 lg L-1, other trace elements were hardly detected or not detected at all. It was remarkable the absence of detectable concentrations of anthropogenically derived metals as lead (Pb) and cadmium (Cd).
