Car cabin air contains cancer causing chemicals, finds study

New Delhi: Alarming findings of a new study has posed a big question on our dependence on cars and automobiles and their impact on our health. As per a study published in Environmental Science & Technology, the quality of car cabin air is extremely hazardous. The study findings indicate the presence of cancer causing chemicals.

What is a flame retardant?

A flame retardant is a chemical or substance incorporated into materials to reduce their flammability and inhibit the spread of fires. In cars, flame retardants are commonly used in various components such as upholstery, carpets, insulation, and electronic components to enhance fire safety. These materials undergo rigorous testing to meet safety standards and regulations, ensuring they withstand heat and flames during potential fire incidents. Flame retardants work by either suppressing combustion or delaying ignition, thereby providing valuable time for occupants to evacuate safely in the event of a car fire, reducing the risk of injuries and fatalities.

The researchers from Duke University and the Green Science Policy Institute found that air flame retardant levels were two to five times higher in the car cabins in the summer compared to winter.

The researchers found high levels of organophosphate esters in cars Organophosphate esters (OPEs) are a class of chemicals commonly used as flame retardants, plasticizers, and additives in various consumer products, including furniture, electronics, textiles, and building materials. While they serve to enhance fire safety and improve product performance, OPEs have raised concerns regarding their potential adverse effects on human health.

Exposure to OPEs can occur through inhalation, ingestion, or dermal contact with contaminated air, dust, or products. Once inside the body, OPEs can disrupt endocrine function, affect neurodevelopment, and induce toxicity in various organs, including the liver, kidneys, and reproductive system. Additionally, some OPEs have been classified as potential carcinogens and mutagens, raising further health concerns.

Research suggests that OPE exposure may be linked to adverse health outcomes such as hormone disruption, respiratory problems, neurobehavioral disorders, and reproductive issues. Therefore, minimizing exposure to OPE-containing products and implementing stricter regulations on their use are essential to safeguard human health and mitigate potential risks associated with these chemicals.

How to reduce the risk?

To reduce carcinogen risks in your car, ensure proper ventilation by regularly opening windows, especially in traffic or after long periods of parking. Avoid smoking inside the vehicle as it releases harmful chemicals. Clean your car's interior frequently to remove dust and debris that may contain carcinogens. Choose non-toxic cleaning products for upholstery and surfaces. Replace air filters regularly to minimize the circulation of pollutants. Park in shaded areas to reduce heat and potential chemical emissions from materials in the car. Lastly, limit exposure to direct sunlight to decrease the formation of harmful compounds in the cabin.
