Scientists are exploring methods to reduce pollution from gas stoves at home, a new frontier after decades of cleanup in automotive, factory, and power plant sectors. Cooking with gas releases nitrogen dioxide, linked to asthma and respiratory diseases. Short-term exposure to nitrogen dioxide from gas stoves often exceeds safety levels set by WHO and the EPA, with the poorest and ethnic minorities most affected.

A study by Stanford University, revealed that gas stoves contribute to 19,000 deaths yearly and 200,000 childhood asthma cases, costing up to $1 billion. Previous studies have flagged gas stoves for emitting nitrogen dioxide and carbon monoxide at unsafe levels.

The new study, published in "Science Advance," is the first to measure nitrogen dioxide levels from gas stoves by household type, race, income, and cooking habits, estimating the cost of preventable asthma cases. It used a model combining federal air quality standards with field measurements from over 100 homes in 5 US states.

Results showed Indian American and Alaskan Native families are most exposed to nitrogen dioxide, followed by Black, Hispanic, and Hispanic people. Those with incomes below $10,000 annually have twice the exposure of those earning over $150,000. Gas disperses more in smaller spaces, exposing smaller homes more than larger ones.

The study suggests replacing gas stoves with electric ones. For those unable to immediately switch, suggestions include using portable induction hobs, air filters, opening windows, and using hoods that vent air outside. However, these solutions can be costly. Tax breaks under the Inflation Reduction Act could help with the transition to electric stoves.

The study authors call for stronger legislation to encourage the switch to electric stoves, particularly in new buildings. The issue of gas stove bans sparked political debate in the U.S last year, with an administration official highlighting health risks and Republicans opposing potential bans. Republican lawmakers are set to discuss a bill next week aimed at restricting Energy Department standards for household appliances, including gas stoves.
