Cross-sectional studies were conducted in three riverside communities in the state of Pará in the Amazon Region of Brazil. Two of these communities, Brasília Legal and São Luís do Tapajós, are located in a watershed exposed to mercury pollution from artisanal gold mining, and the third, Santana do Ituqui, is outside this area. The studies were based upon a community census and included all persons volunteering for participation in each community. All participants were surveyed by questionnaire…

Mercury in Fish-eating Communities of the Andean Amazon, Napo River Valley, Ecuador

The study shows that sociocultural factors are important in determining mercury exposure, and two village communities consume different species of fish with different frequencies, leading to differential exposure and mercury concentrations in hair samples.

Evaluation of mercury exposure and sensory symptoms in adults from three riverine communities in Pará State, Brazil concluded that despite the mercury exposure levels, there was a low frequency of sensory alterations according to conventional neurological testing.

Mercury Speciation in Hair of Children in Three Communities of the Amazon, Brazil

Levels of mercury above the limit established by the World Health Organization and the strong correlation coefficient between the communities suggests the hair as an excellent biomarker of human exposure to organic mercury in riverside populations of the Tapajós, which has the intake of fish daily as main source of protein dietary.

Hair mercury levels in Amazonian populations: spatial distribution and trends

Hair mercury levels in the Amazonian regions seem to be very heterogenic, depending on several factors, and there is no obvious spatial trend and there are many areas that have never been studied.

Mercury and methylmercury concentration assessment in children's hair from Manaus, Amazonas state, Brazil

Future studies to set Hg and MeHg levels in hair of children in Brazil should take into account and assess the diversity of the country, mainly in terms of eating habits, socio-economic and cultural aspects.

Although average exposure levels may not have changed during recent years, prenatal exposure levels are unknown, and exact dose relationships cannot be generated, however, the current mercury pollution seems sufficiently severe to cause adverse effects on brain development.
