TL;DR: Fish and hair samples as the best indicators of human methylmercury contamination were investigated in the main cities and villages along the Tapajós river basin and critical fish, areas, and more exposed human groups are identified.
Journal ArticleDOI
Methylmercury pollution in the Amazon, Brazil
Hirokatsu Akagi,Olaf Malm,Yoshihide Kinjo,Masazumi Harada,Fernando J.P. Branches,Wolfgang C. Pfeiffer,Hiroo Kato +6 more
TL;DR: In this paper, the authors evaluated the extent of environmental mercury pollution due to goldmining activities in the Amazon, and determined the concentrations of total mercury and methylmercury for human hair and fish samples from five fishing villages.
Journal ArticleDOI
Mercury in feathers of wild birds from the mercury-polluted area along the shore of the Shiranui Sea, Japan.
TL;DR: In this paper, the total mercury content in the feathers of 95 stuffed, wild birds collected all over the shore of the Shiranui Sea (where Minamata disease occurred in many towns and villages in the 1960's) was measured.
Journal ArticleDOI
Methods of removing external metal contamination from hair samples for environmental monitoring
TL;DR: EDTA was found to be the most suitable of these washing agents for removing external contaminant metals and further elucidation is needed before a standard method of hair washing can be established.
Journal ArticleDOI
A study of the sources of external metal contamination of hair
TL;DR: The experiments with soil demonstrated the importance of water in the movement of iron from soil to hair and the role played in this process by biological factors such as soil bacteria.
