A pilot study led by IDAEA detects chemical pollutants in blood and placenta of pregnant women
24 November 2021
A study led by the Institute of Environmental Assessment and Water Research (IDAEA-CSIC) in collaboration with the Barcelona Institute for Global Health (ISGlobal), a centre supported by the “la Caixa” Foundation, has evaluated chemical pollutants accumulated in pregnant women. A group of 19 women from Barcelona participated in this study, carried out between September 2019 and March 2020, where 42 potentially harmful chemical compounds of anthropogenic origin were detected.
Blood and placenta samples from pregnant women were analysed. Among the compounds found there were pesticides, insect repellents, cosmetic derivatives, and industrial compounds such as flame retardants or plastic additives. “Although there is no evidence that the levels found pose a risk to human health, this study should raise awareness of the compounds we are exposed to on a daily basis and to which we should reduce our exposure,” says IDAEA-CSIC researcher Pablo Gago Ferrero, lead author of the study. This is especially relevant in the case of plastic additives such as phthalates, which have been linked to endocrine diseases and which should be monitored in detail.
