Most people consider the consumer products they use in their daily lives safe, and manufacturers often do not need to disclose the ingredients in their products, making it difficult for individuals to know what they are being exposed to and the potential health implications. Research indicates that people tend to underestimate the presence of toxic substances in these consumer products. The truth is many consumer products commonly used daily may release toxic gases, which can severely threaten human health.
Researchers from Silent Spring Institute and the University of California, Berkeley, conducted a study using data from the California Air Resources Board. The study specifically targeted 33 VOCs listed in California’s Proposition 65. The data included information on VOC concentrations across different product categories and detailed sales volume for each product sold in California.
The analysis showed that over 100 products contain volatile organic compounds (VOCs) listed under Proposition 65. Among them, 30 products (including various personal care products) contain harmful chemicals that pose potential health risks and require particular attention.
Another area of concern pertains to the use of products in occupational environments, where workers often come into contact with multiple products, each potentially containing at least one hazardous chemical. For example, adhesives have been found to contain several VOCs listed under Proposition 65, indicating that workers may be exposed to multiple toxic substances by using just one product.
Similarly, professionals working in nail and hair salons use nail polish, nail care items, shampoos, and cosmetics, while cleaning personnel employ various cleaning agents, solvents, detergents, and other household products. These products may contain multiple VOCs listed under Proposition 65.
According to the California Air Resources Board estimates, approximately 2.75 tons of methylene chloride (dichloromethane) was emitted daily from consumer products in 2020, with paint removers being the primary source. The U.S. Centers for Disease Control and Prevention (CDC) states that methylene chloride can harm the eyes, skin, liver, and heart. It may even cause cancer. Exposure to the chemical can result in drowsiness, nausea, dizziness, numbness, and tingling limbs. Severe exposure can lead to loss of consciousness and even death.
The researchers suggest that the United States Environmental Protection Agency (EPA) consider regulating the following five additional chemicals under the Toxic Substances Control Act (TSCA) that are not currently being evaluated: ethylene oxide, styrene, 1,3-dichloropropene, diethanolamine, and cumene.
- Avoid or limit the use of products with high VOCs: Look for “Low VOCs” information on labels and choose products with lower VOC content; purchase only the necessary quantity and dispose of any leftover or unused products safely; refrain from smoking and keep a smoke-free environment in all buildings.
- Add ventilation when using products containing VOCs indoors: Allow new carpets to air outdoors before installation to release VOCs; avoid storing products with VOCs indoors, including in attached garages; make sure the office ventilation system is working effectively to minimize VOCs produced by copiers or printers.
