Abstract Background Fish is considered protective for coronary heart disease (CHD), but mercury (Hg) intake from fish may counterbalance beneficial effects. Although neurotoxic effects of methylmercury (MeHg) are well established, cardiovascular still debated. The objective the present study was to evaluate blood pressure in relation Hg exposure and consumption among a non-indigenous fish-eating population Brazilian Amazon. Methods conducted 251 persons six communities along Tapajós River,...
Mercury (Hg) is a ubiquitous environmental contaminant with neurodevelopmental and immune system effects. An informative biomarker of Hg-induced immunotoxicity could aid studies on the potential contribution to immune-related health effects.Our objectives were test hypothesis that methylmercury (MeHg) exposures affect levels serum biomarkers examine interactions between Hg selenium (Se) in terms these responses.This cross-sectional epidemiological study assessed adults living along Tapajós...
Age-related cataracts (ARCs) are an important cause of blindness in developing countries. Although antioxidants may be part the body's defense to prevent ARC, environmental contaminants contribute cataractogenesis. In fish-eating populations lower Tapajós region, elevated exposure mercury (Hg) has been reported, and blood levels selenium (Se) range from normal very high (> 1,000 microg/L).We examined ARCs relation these elements among adults or = 40 years age) 12 riverside...
Selenium (Se) is a well-known anti-oxidant with critical role in the proper functioning of nervous and muscle functions. Se deficiency has been associated both cognitive neuromotor impairment, while sensory motor deficits have attributed to excess Se. In Lower Tapajós Region Brazilian Amazon, riverside populations present wide range levels. These fish-eating communities among highest mercury (Hg) exposures reported world today, recently, lead (Pb) exposure identified. Some studies suggest...

BackgroundLittle is known about the influence of toxic exposures on reduced life expectancy in First Nations people Canada. The Grassy Narrows Nation community have lived with consequences one worst environmental disasters Canadian history. In early 1960s, 10 000 kg mercury (Hg) was released into their aquatic ecosystem. Although Hg concentration fish, dietary staple, decreased over time, it remains high. We aimed to examine whether elevated exposure time contributes premature mortality...
Background: For 60 y, the people of Asubpeeschoseewagong Anishinabek (Grassy Narrows First Nation) have endured effects massive mercury (Hg) contamination their river system, central to traditions, culture, livelihood, and diet. In years following Hg discharge into English–Wabigoon River system by a chloralkali plant in early 1970s, there was dramatic increase youth suicides. Several authors attributed this solely social disruption caused disaster. Objective: This research examined possible...
Abstract Background Since the 1960’s, mercury (Hg) contamination of aquatic environment Asubpeeschoseewagong Anishinabek (Grassy Narrows First Nation) territories has impacted community members’ traditions, culture, livelihood, diet and health. Despite decreasing Hg exposure over time, a recent study suggested that long-term contributed to later-life symptom clusters nervous system dysfunction. Here, objective was evaluate, 5 years later, prevalence progression these symptoms examine...
Abstract Background The watershed in Asubpeeschoseewagong Netum Anishinabek (Grassy Narrows First Nation) territory has been contaminated by mercury (Hg) since 1962, resulting very high Hg concentrations fish, central to the community’s culture, traditions, economy and diet. Biomarkers of exposure (umbilical cord blood hair/blood samples), monitored between 1970 1997, decreased over time. A recent Grassy Community Health Assessment (GN-CHA) survey included current symptoms nervous system...
