News from CREAL
A study led by CREAL, from the ISGlobal Alliance, and the Harvard School of Public Health has found that methylmercury consumed during pregnancy has no effect on the neurodevelopment of 8-year old children living in a region with a low consumption of fish, unless they have a genetic predisposition. However, it was found that 30% of these children have this type of bias, due to their vulnerability to mercury toxicity.
In order to extract these findings, researchers have studied 1,135 children of 8 years of age from Bristol (United Kingdom). This age is "ideal" for neuropsychological tests, together with the analysis of this pollutant through their umbilical cords.
