Prenatal methylmercury exposure and children: neurologic, developmental, and behavioral research.
Mercury is present in the earth's crust and is methylated by bacteria in aquatic environments to methylmercury (MeHg). It is then concentrated by the food chain so predatory fish and sea mammals have the highest levels. Thus, consuming seafood leads to exposure. MeHg readily crosses the placenta and the blood-brain barrier and is neurotoxic. The developing fetal nervous system is especially sen...
متن کاملMethylmercury exposure and developmental neurotoxicity
We are concerned that certain aspects of the systematic review on methylmercury (MeHg) exposure from seafood consumption and the risk of developmental neurotoxicity published in the Bulletin of World Health Organization could be misinterpreted.1 Specifically, the review does not address the issue of whether naturally-occurring, background levels of prenatal exposure to MeHg from maternal fish c...
متن کاملDevelopmental and behavioral effects of prenatal amitraz exposure in rats.
The effects of prenatal amitraz exposure on physical and behavioral parameters of rats were studied. Pregnant rats were orally gavaged with amitraz (20 mg/Kg) or with distilled water (1.0 ml/Kg) on Days 1, 4, 7, 10, 13, 16, and 19 of pregnancy. After birth, cross-fostering was performed thus generating the following groups: control pups nursed by control dams (CC); control pups nursed by treate...
متن کاملPrenatal Methylmercury Exposure and Developmental Outcomes: Review of the Evidence and Discussion of Future Directions
I conducted a review of the published literature to assess the strength of the evidence for an association between prenatal exposure to methylmercury (MeHg) and subsequent child development. I identified 12 studies on this subject published since 1980. Of these, 3 were longitudinal studies--2 conducted in the Seychelle Islands, and 1 in the Faroe Islands. Nine were cross-sectional studies condu...
متن کاملMaternal seafood diet, methylmercury exposure, and neonatal neurologic function.
OBJECTIVE To determine whether neonatal neurologic function is adversely affected by seafood contaminants from maternal diet during pregnancy. STUDY DESIGN One hundred eighty-two singleton term births were evaluated in the Faeroe Islands, where marine food includes pilot whale. Maternal serum, hair, and milk and umbilical cord blood were analyzed for contaminants. Levels of essential fatty ac...
