Portions of the work benefited from research supported by the U.S. Environmental Protection Agency and the South Coast Air Quality management District. Partial funding also was provided by the U.S. Department of Energy. This CalTech research lists 64 previously unknown chemicals that are produced when natural gas is burned indoors. But there's more. Some PCBs contaminating gas pipes pass unchanged, directly into the consumers gas appliances and indoor living environment.
Sulfides cause asthmatic attacks, breathing difficulties, allergies and can cause death.
British researchers find that women who cook with gas are at least twice as likely to experience wheezing, shortness of breath, and other symptoms of asthma as those who prepare meals using electric cook tops and ovens. Though smokers were no more likely to develop symptoms than nonsmokers, those who did experience problems tended to develop more serious ones. Each year they produce 224.9 Billion pounds of gas pollution that's dumped into the environment, indoor air, your bodies and food. By comparison, 224.9 Billion pounds of natural gas combustion is more than tobacco or second-hand smoke produces. Therefore, gas combustion is the largest and most dangerous pollution source consumers are faced with.
