Abstract

OTHAX, Natalia et al. Integrated health risk by substances in water resources of Tres Arroyos, Argentina. Acta bioquím. clín. latinoam. [online]. 2013, vol.47, n.4, pp.681-692. ISSN 0325-2957.

The objective of this work was to analyze the non-carcinogenic health risk from certain substances (inorganic, phenolic, heavy metals and pesticides) in surface waters and groundwater in the town of Tres Arroyos. The analysis was performed using the basic model of health risk analysis considering probabilistic USEPA for children of three age groups (5, 10 and 15). Residential and recreational type scenarios were integrated, based on exposure through ingestion and dermal contact with water. In all three age strata, the results indicate that the values of the integrated risk (residential risk + recreational risk) were significant and decreasing with respect to age, being arsenic the largest contributor through the residential ingestion pathway.
