“BPA Free” Plastic Bottles Are They Safe Or Not?

A study published in the journal PLOS ONE warns about the toxic effects of bisphenol S, a chemical that many manufacturers use as an alternative to bisphenol A (BPA) in materials in contact with food and thermal papers.

The research of the Group of Biology and Environmental Toxicology of the UNED, in collaboration with the Laboratory of Ecotoxicology of INIA, has proved that the BPS is also an endocrine disruptor.

It is not enough to put BPA free in the plastic bottle. It may contain BPS, which can be equally harmful.

Bisphenol A is used in the manufacture of plastics (for example, reusable plastic tableware and bottles, sports equipment, CDs and DVDs), epoxy resins (used to coat the interior of water pipes and cans) and thermal paper of datáfonos, boxes of supermarket or automatic tellers.

The main exposure to this substance is through diet, by migration of BPA from materials that are in contact with food.

BPA can damage the intestine, liver and kidneys, although hormonal effects related to physical, neurological and behavioral development are the most worrying effects.

In recent years, different international regulations have prohibited or limited their use in a variety of products, such as baby bottles or children’s toys.

Currently, BPA is considered a toxic substance for human reproduction and capable of causing endocrine alterations and adverse effects both in humans and in the environment.

The industry looks for alternative substances such as bisphenols S, F, AP or Z, among others. Products that contain these alternatives in their composition are often labeled as “BPA free” to attract more informed consumers.

The scientists verified the effects of BPS on the activity of 14 genes related to hormonal pathways, cellular stress mechanisms and responses to toxic exposure.
