Plastics and their associated chemicals have become an unavoidable part of our daily lives. Recent research conducted in southern California has revealed alarming levels of exposure to plasticizers, the substances used to soften plastics and make them more flexible.
Toxicologist David Volz from the University of California, Riverside (UCR) has concluded that the average urban resident in southern California is exposed to high and persistent levels of plasticizer chemicals. These chemicals, although not all known to be toxic, have been linked to serious health issues. One such chemical compound, DEHP, has been banned in IV bags and medical tubing in California due to its potential to increase the risk of cancer, harm the reproductive system, and affect child development.
Despite the ban on DEHP in children’s products since 2009, the new research suggests that residents in southern California are still being exposed to this chemical and others like it at concerning concentrations. The study involved equipping 137 students at UCR with silicone wristbands to measure their exposure to 10 known plasticizers. The results were shocking, revealing high levels of these potentially dangerous pollutants in the environment.
Phthalates, a family of chemicals that include DEHP and DiNP, are commonly found in food packaging, vinyl, cosmetics, and household products. These chemicals can be ingested, absorbed through the skin, or inhaled, leading to widespread exposure among the population. The EPA is currently evaluating the toxicity of phthalates in light of new evidence suggesting their carcinogenic potential.
The study published in Environmental Research raises concerns about chronic exposure to DiNP, DEHP, and a newer plasticizer called DEHT in urban areas of California. While DEHT was introduced as a safer alternative to phthalates, its potential toxicity in humans remains largely unknown. The EPA’s preliminary draft review indicates that DiNP may cause liver damage and could be carcinogenic at higher levels of exposure.
Overall, the findings highlight the need for further research and regulation of plasticizers to protect public health. The pervasive presence of these chemicals in our environment underscores the importance of reducing exposure and finding safer alternatives for everyday products.
