Scientists have found that gas stoves are more harmful than passive smoking.

According to the work of American researchers, the use of a gas stove can increase the concentration of benzene in the room. This figure is higher than with passive smoking, or even higher than the level observed near oil and gas facilities. Low temperature stoves and gas ovens also emit significant amounts of benzene. However, even low doses of benzene in the air increase the risk of developing various types of cancer, including lymphomas and leukemia.
