BioMed Central Cleaning up mercury pollution and reducing prenatal exposure to the neurotoxin methylmercury (MeHg) could save the European Union 10,000 million per year, finds a new study published in BioMed Central's open access journal Environmental Health. New estimates suggest that between 1.5 and 2 million children in the EU are born each year with MeHg exposures above the safe limit of 0.58µg/g and 200,000 above the WHO recommended maximum of 2.5µg/g. While some...
