Prenatal Exposure to Mercury and Adverse Birth Outcomes in Rio de Janeiro, Brazil: Rio Birth Cohort Study (PIPA Project)

“…Hallmark studies on fetus and newborn susceptibility to prenatal Hg exposure are available, for example on the poisoning episodes in Japan and Iraq (Bose-O' Reilly et al, 2010;Patel et al, 2019). In Brazil, most reports concerning prenatal Hg exposure relate to Amazonian communities, which often exhibit relatively high exposure levels due to the large amounts of Hg-contaminated fish and shellfish consumption (Dutra et al, 2012;Hacon et al, 2000;Santos et al,2007). On the other hand, studies assessing this kind of exposure and its effects on Brazilian urban area birth outcomes are still lacking.…”
