MUSTRA, Carla et al. INFLUENCE OF METHYLMERCURY ON FETAL GROWTH AND DEVELOPMENT. Acta Port Nutr [online]. 2021, n.26, pp.70-73.  Epub Jan 12, 2022. ISSN 2183-5985.  https://doi.org/10.21011/apn.2021.2610.

Pregnancy is a period of great susceptibility of exposure to environmental contaminants, such as heavy metals, including methylmercury, since it can cross the placental and blood-brain barrier, impairing fetal growth and development. This review is intended to understand mercury metabolism and its impact on the health of pregnant women and fetal development and identify foods with a higher risk of methylmercury contamination and propose healthier options. Through literature review, studies demonstrate a correlation between fish consumption and the levels of methylmercury in the body and associate these levels with cognitive deficits in children whose mothers were excessively exposed to this element. However, fish is also an essential source of several important nutrients, proteins, vitamins, minerals and fatty acids with a protective effect on exposure to mercury. It is necessary to inform pregnant women about the impact of mercury on fetal growth and development and its primary sources. It is crucial to raise awareness for the consumption of small fishes and low trophic level, taking into account their benefits for maternal and fetal health and contamination risks.
