New findings reveal that individuals with an average sense of smell may unknowingly be living with natural gas leaks. According to a peer-reviewed study in the scientific journal Environmental Research Letters, minor leaks can deteriorate indoor air quality by emitting various hazardous pollutants, such as benzene—a carcinogen detected in 97% of natural gas samples throughout North America.
“While these smaller leaks are not large enough to cause gas explosions, hard-to-smell leaks are common,” said lead author and PSE Healthy Energy Scientist Sebastian Rowland. “The fact that they are so small makes them hard to identify and fix, which can lead to a persistent indoor source of benzene and methane.”
