Abstract

Arsenic (As) is a natural element of the earth's crust. Due to the health effects caused by its exposure, it has a great relevance in toxicological studies. The high levels of As in groundwater in Argentina and Chile are widely studied and known. However, in Uruguay there are few research studies based on the levels of As in water. In this work the determination of the total As in water samples was carried out, using atomic absorption spectrometry with hydride generation (HG-AAS). The methodology was based on the standardized method of the American Public Health Association APHA 3114 B. We evaluated linearity, accuracy and veracity as performance parameters for its implementation. A total of 49 samples of surface and underground water were analyzed. The results did not exceed the standards level established in Uruguayan regulations (20 μg L-1). Also, higher values were observed in groundwater rather than in surface water. This research is an initial work to know the As levels in water used for domestic purposes and rice plantations in Uruguay.
