Excretion of arsenic (As) in urine of children, 7--11 years, exposed to elevated levels of As in the city water supply in Hermosillo, Sonora, Mexico
- Centro de Investigaciones en Alimentacion y Desarrollo, Hermosillo (Mexico)
Arsenic (As) is a common element in the environment with many industrial uses, but it also can be a contaminant in drinking water and present serious health concerns. Earlier studies on the quality of drinking water in the city of Hermosillo, Sonora, Mexico, showed high levels of As in water from wells located in the northern part of the city. Additionally a high positive correlation between the levels of Fluoride (F) and As in the same wells was found. Therefore, the objective of this study was to determine the excretion of As in children, 7--11 years of age, that had been exposed to elevated levels of As in their drinking water. Twenty-four-hour urine samples and a water sample taken directly in the home were collected from school age children living in two different areas with known high levels of As in their drinking water. A control group with normal levels of As in their water was also included.
