The health of Latin Americans exposed to polluted rivers : a triple-blind observational study.
We conducted a cross-sectional survey simultaneously in six Latin American nations among people living near a river known to be polluted in each country.
Trace metals (arsenic, mercury and lead) were selected as indicators of exposure to industrial effluents.
Within each country, we contrasted probability samples from three types of communities:
one upstream of point sources of pollution and thus little exposed;
one downstream from a site of major development;
and one with intermediate exposure.
The outcome variables were health status measures elicited by questionnaire and biochemical measures of blood and urine.
