Resumo
The objective of the work is to evaluate the mercury exposure of children living in
the artisanal gold mining are and in a control area, without mining. A cross-sectional
study was conducted with children living in the municipalities of Chapada de Natividade
and Porto Nacional, in the State of Tocantins, where hair samples were collected
for laboratorial analysis of mercury concentrations, comparing between municipalities,
gender, monthly fish consumption, profession of parents and the presence of
amalgam in dental restorations. The participating children were selected from informations
registered in the cadaster of the service of basic health assistance of Brazil
(SUS).The age range chosen was of children from 5 to 6 years, with the aim of not
including older children, which might be already submitted to work in the artisanal
gold mining activities. The hair samples were analyzed by the methods of neutron
activation analysis and also by means of the DMA (Direct Mercury Analyzer) equipment,
in the last case being a partnership with CETESB. There was no evidence of
mercury-related diseases in the studied children. The mean concentration of mercury
in children in Chapada de Natividade was significantly higher than in Porto Nacional.
Children exposed to artisanal gold mining areas have higher concentrations of mercury
than children living in non- artisanal gold mining areas. There was no significant
relationship between mercury concentrations and gender, monthly fish consumption,
parental profession and amalgam presence in dental restorations.
