A new study has found a link between exposure to certain chemicals in the uterus and lower intelligence in children.

The study, which was conducted by researchers at Columbia University’s Mailman School of Public Health, looked at the impact of exposure to polybrominated diphenyl ethers (PBDEs) on the cognitive development of children.

What are PBDEs?

PBDEs are a type of flame retardant that was commonly used in furniture, electronics, and other household items until it was banned in 2004.

However, because PBDEs do not break down easily, they can still be found in the environment and in the bodies of people who were exposed to them before the ban.

How was the study conducted?

The study looked at data from 328 women who were pregnant between 1998 and 2002 and living in New York City. The women provided blood samples during their third trimester of pregnancy, which were tested for the presence of PBDEs.

The children born to these women were then followed and their cognitive development was assessed using a standardized test when they were between the ages of 5 and 9.

What did the study find?

The study found that the children who had been exposed to higher levels of PBDEs in utero scored lower on the cognitive tests than those who had lower levels of exposure.

Specifically, they scored lower in areas related to verbal comprehension, working memory, and processing speed.

What does this mean?

This study adds to the growing body of evidence that exposure to certain chemicals during fetal development can have long-term effects on cognitive function.

It also highlights the need for continued research into the impact of environmental pollutants on human health.

What can be done to reduce exposure to PBDEs?

While PBDEs are no longer used in new products, they can still be found in older items, particularly in older furniture and electronics. To reduce exposure, it is recommended that people avoid buying used items and opt for newer, PBDE-free products.

It is also important to properly dispose of any items that contain PBDEs, rather than throwing them in the garbage.

What other chemicals should we be concerned about?

PBDEs are just one type of chemical that has been linked to negative health outcomes. Other chemicals of concern include lead, mercury, and phthalates, which can be found in a variety of household items.

It is important to be aware of potential sources of exposure and take steps to reduce risk whenever possible.

Conclusion

The findings of this study add to the growing body of research on the impact of environmental pollutants on human health.

While more research is needed to fully understand the long-term effects of exposure to PBDEs and other chemicals, it is clear that we need to take steps to reduce our exposure whenever possible.
