A study published last week in the journal Environmental Science & Technology found at least 12 hazardous air pollutants, including benzene, a carcinogenic, are being emitted by virtually all gas ranges. The study, limited to California, included 159 stoves in 16 counties. It found benzene emitted from 99% of the sampled stoves. Here’s a link for that study.
Although the study did not include other gas appliances such as forced air furnaces and water heaters, it makes sense that the same pollutants are being emitted from those and other gas appliances, too.
Gas appliances are also a source of carbon monoxide, a poisonous gas, and carbon dioxide, a greenhouse gas, which is also unhealthy in high concentrations.
This report adds another reason why homeowners should consider abandoning natural gas (or propane) and moving toward having all-electric homes, especially now that there are widely available and efficient heat pump HVAC systems, heat pump water heaters, and induction cooktops. Rita and I have used all three of these appliances plus an electric grill, which we love.
