Distribución de fuentes de plomo en sangre de mujeres en edad reproductiva que viven cerca de jales en Taxco, Guerrero, México: un estudio isotópico

Abstract

The concentration and isotopic composition of lead in the blood of women of reproductive age (15-45 y) exposed to multiple sources in two rural communities of the mining region of Taxco, Guerrero in southern Mexico were determined in order to identify specific contributing sources and their apportionment and to trace probable ingestion pathways. Our data indicate that more than 36 % of the studied women have blood lead concentrations above 10 µg dL-1 and up to 87 % above 5 µg dL -1. Tailings contain between 2128 and 5988 mg kg-1 of lead and represent the most conspicuous source in the area
