"Study Reveals Hidden Benzene Risks in Natural Gas"

A new study published in Environmental Research Letters reveals that small, often undetectable natural gas leaks can introduce hazardous air pollutants, including benzene, into indoor environments. Researchers found benzene in 97% of natural gas samples across North America, with significant variations in odorant levels and benzene concentrations among different cities. The study highlights the limitations of relying solely on smell to detect gas leaks and suggests that improved transparency, stricter odorization standards, and enhanced leak detection methods are necessary to protect public health.
