The deleterious effect of endocrine disrupters on the development of the nervous system is known
Notably, it has been shown by research on animals. But a study by researchers at the national Institute of health and medical research (Inserm), made public Friday, September 29, goes further. It has analysed the consequences for children of women exposed, during pregnancy, these chemicals, ubiquitous substances in a multitude of consumer products like plastics or cosmetics. Published in the journal Environmental Health Perspectives, this work highlighted that exposure of pregnant women to some phenols and phthalates is associated with disorders of the behaviour of boys from 3 to 5 years.
Among these, three chemicals are of concern: bisphenol A, triclosan and dibutyl phthalate (DBP). Bisphenol A, which has been prohibited in all food containers in 2015 – a date subsequent to the conduct of this study-, is always used in a multitude of common items (CD’s, bike helmets, etc.). Triclosan, meanwhile, is an antibacterial agent found in SOAP, toothpaste or gels showers. Its use has been prohibited in the clothes and restricted in certain cosmetics such as mosses to shave.
Finally, the DBP is used as a plasticizer in plastics type PVC, some glues, nail varnishes or lacquers for hair.
” The strengths and difficulties questionnaire”study focused on 529 little boys of the mother-child cohort Eden, established by Inserm. The mothers of these boys were recruited when they were pregnant, between 2003 and 2006, in the CHU in Nancy and Poitiers.
Des samples of urines were collected in the middle of the 2nd trimester of pregnancy. Then the mothers were asked to fill out a questionnaire on the 3rd.
