Airborne plastic chemical levels shock researchers

A recent study from UC Riverside has revealed alarming levels of airborne plasticizers, particularly phthalates, in Southern California. These chemicals, known for their use in various products to enhance flexibility, have been linked to reproductive toxicity and cancer. The research highlights the presence of both ortho-phthalates, which have been phased out due to health concerns, and non-ortho-phthalates, whose health impacts are less understood. Researchers monitored two groups of undergraduate students using silicone wristbands to collect data on chemical exposure over several days. The findings indicated that for every gram of wristband material, there were between 100,000 and 1 million nanograms of three specific phthalates: DiNP, DEHP, and DEHT. Both DiNP and DEHP are listed under California's Proposition 65 for their potential health risks. The study suggests that despite the introduction of DEHT as an alternative, overall exposure levels remain high. The researchers emphasize the need for reducing plastic production and consumption to mitigate these health risks, as the pervasive nature of these chemicals indicates widespread exposure across different environments.

- Airborne plasticizers, particularly phthalates, are found at alarming levels in Southern California.

- The study utilized silicone wristbands to measure chemical exposure among students.

- DiNP and DEHP are known reproductive toxins and are included in California's Proposition 65.

- The introduction of DEHT as an alternative has not significantly reduced exposure levels.

- Researchers advocate for decreased plastic production and consumption to lower health risks.
