Abstract

Environmental health risks by arsenic consumption in water wells in the Cape region, Mexico H. Romero-Schmidt, A. Naranjo-Pulido, L. Mendez-Rodriguez, B. Acosta-Vargas & A. Ortega-Rubio Centra de Investigaciones Biologicas del Noroeste Baja California Sur, Mexico Abstract The aim of this work was to evaluate the concentration of arsenic in wells of the San Antonio-El Triunfo region, located in the Baja California Sur (BCS) Mexican State. At this region mineral mining activities flourish during the XIX century. As a by- product of these activities there were deposited on the soil thousands of tons of debris, which contains high quantities of arsenic. During the summer months of 1997 we developed fieldwork in order to sample these wells. Concentration of arsenic was determined using the Chapman and Parket [1] techniques. The results were statistically analyzed by ANOVA tests. Our results indicates that all the groundwater sampled in the wells of the region exceeds the Mexican off
