Plastic chemicals in cough bombs increase the risk of asthma in schoolgirls
The European Chemicals Agency (ECHA) placed BPA on its list of substances of “high concern” in 2017. Since then, a number of countries have restricted its use, prompting some manufacturers to change their use. replace BPA with other bisphenols.
Since bisphenols are known to be present in breast milk and that they can cross the placental barrier, the researchers wanted to know if prenatal exposure to these chemical compounds is linked to health problems. respiratory failure in later years.
They studied urine samples taken during pregnancy from more than 3,000 women from six European countries (Spain, France, Greece, Norway, the Netherlands and the United Kingdom) collected from 1999 to 2010 and their children’s respiratory health data collected years later. through questionnaires and spirometry.
Analysis of urine samples revealed a high percentage of BPA, found in 90% of the samples. Other bisphenols were studied less commonly at the time these samples were collected.
The Netherlands was the only country that found a notable presence of other bisphenols among the study participants (bisphenol F in 40% of the sample and bisphenol S in 70%). This finding is probably due to the early switching of substitutes for bisphenol A in that country.
The results of this study suggest an association in girls between maternal urine bisphenol A levels during pregnancy and an increased risk of asthma and wheezing at school age.
These results are consistent with previous studies, which also reported that bisphenol A affects respiratory health in childhood.
The researchers believe the effect may be because bisphenol can cross the placental barrier and interfere with a child’s immune and respiratory systems during development.
