Exposure to dangerous chemicals found in consumer goods throughout the trimester of pregnancy could lead to lower IQ in children by age seven.
Researchers quantified 26 compounds in the urine and blood of 718 moms throughout the first trimester of their pregnancies at the analysis of Swedish mothers and children, called SELMA.
Researchers afterward followed with all the kids at age and found that those whose mothers had higher amounts of those compounds in their system through pregnancy had significantly lower IQ scores–especially boys, whose scores have been reduced by 2 factors.
Within the mix, bisphenol F (BPF), a BPA-replacement chemical, made the maximum contribution to reducing children’s IQ, indicating that BPF is no safer for kids than BPA, reported that the study printed in environmental International’.
A number of the chemicals just remain in the body a brief time, meaning even short-term vulnerability might be harmful, so researchers consider this suggests that preventing exposures to pregnant women or men seeking to become pregnant is essential to preventing neurological injury to kids.
“This research is important because most studies assess one compound at a time nevertheless, individuals are exposed to a lot of chemicals at precisely the same time, and several exposures might be detrimental even when every individual compound reaches a very low level,” explained Eva Tanner, PhD, MPH, postdoctoral researcher at the Department of Environmental Medicine and Public Health in the Icahn School of Medicine at Mount Sinai.
Carl-Gustaf Bornehag, PhD, Professor at Karlstad University, said it demonstrates that exposure to combinations of chemicals in normal consumer products can impact child brain development and some substances considered to be safer, more such as BPF, might be no safer for kids.
The compounds interfere with hormone action, even at reduced levels. Past studies link several suspected endocrine disruptors, such as phthalates and BPA, to neurodevelopmental problems in children.
A few of the chemicals cross the placenta when pregnant, exposing the fetus and possibly causing irreversible developmental harm.
While stopping vulnerability into a short-lived pollutant may remove adverse consequences in adults, exposure during critical phases of deadly development might be irreversible, using subtle endocrine changes possibly affecting health consequences in adulthood, Dr. Tanner explained.
Dr. Tanner said this study only evaluated exposure in one time throughout early pregnancy, so more study has to be done to understand how ailments throughout subsequent childhood and pregnancy may influence the outcomes.
The investigators note that many of these compounds studied only remain in the body for a brief quantity of time, therefore the moms in the study might have experienced added exposures before or following their urine and blood samples were obtained.
