A recent study has found that exposure to certain everyday chemicals can lead to a reduction in IQ in children. The study, published in the journal Environmental Health Perspectives, analysed data from almost 700 pregnant women and their children.

It found that children exposed to high levels of phthalates, which are used in plastics, as well as some cosmetics and personal care products, had an IQ that was on average six points lower than those who weren’t.

What are Phthalates?

Phthalates are a group of chemicals that are commonly used to add flexibility and softness to plastics. They are also used in some cosmetics and personal care products, such as fragrances, hair sprays, and soaps.

In addition, they can be found in some food packaging and medical devices. Because phthalates are not chemically bound to the products that they are added to, they can leach out over time, and this is how people are exposed to them.

How were Children Exposed to Phthalates?

The study found that the children in the study were exposed to phthalates either through their mother’s prenatal exposure, or through the phthalates in their homes.

The researchers found that phthalates were present in household dust, suggesting that they were released from common household products, such as flooring, upholstery, and cleaning products.

Other Chemicals Linked to IQ Loss

The study also found that exposure to other chemicals, such as perfluoroalkyl substances (PFASs) and polychlorinated biphenyls (PCBs), were also linked to a reduction in IQ.

PFASs are chemicals used in non-stick coatings, such as those used in some cookware, and PCBs are chemicals that were commonly used in transformers, capacitors, and other electrical equipment.

What Can be Done to Reduce Exposure to These Chemicals?

There are a number of things that can be done to reduce exposure to these chemicals. Firstly, avoid using plastics for food storage and instead use glass or stainless steel containers.

Secondly, avoid using cleaning products that contain phthalates or other chemicals that have been linked to IQ loss. Thirdly, vacuum and dust your home regularly to reduce exposure to household dust.

Conclusion

This study adds to the growing body of evidence that exposure to chemicals in our everyday lives can have a harmful effect on our health.

While it is difficult to completely avoid exposure to these chemicals, there are steps that we can take to reduce our exposure. Ultimately, it is up to manufacturers and regulators to ensure that they are not using or allowing the use of chemicals that are harmful to our health.
