Speaking of those exhaust fans, the boffin class got the memo.
The U.S. Environmental Protection Agency does not have indoor air quality standards for nitrogen oxides, but the researchers found that the government's 100 parts per billion limit for one hour of outdoor exposure is "regularly exceeded if stoves are used without adequate indoor ventilation," such as not having a hood or not turning it on while cooking.If all you're doing is boiling water for mushy vegetables, or heating up canned goods, I suppose that electric stove is good enough. Maybe Jess depends on her companions to do the cooking.
"I don't want to breathe any extra nitrogen oxides, carbon monoxide, or formaldehyde," Jackson said in a statement. "Why not reduce the risk entirely? Switching to electric stoves will cut greenhouse gas emissions and indoor air pollution."
Dip into the press release touting the research, dear reader, and note two things. First, "Hood use and ventilation help reduce concentrations of nitrogen oxides and other co-produced pollutants in kitchen air, yet surveys show that home cooks on average use hoods for kitchen ventilation only 25–40 percent of the time." Just turn it on. Second,
The highest emitters were cooktops that ignited using a pilot light instead of a built-in electronic sparker. Methane emissions from the puffs of gas emitted while igniting and extinguishing a burner were on average equivalent to the amount of unburned methane emitted during about 10 minutes of cooking with the burner. Interestingly, the researchers found no evidence of a relationship between the age or cost of a stove and its emissions. Most surprising of all, more than three-quarters of methane emissions occurred while stoves were off, suggesting that gas fittings and connections to the stove and in-home gas lines are responsible for most emissions, regardless of how much the stove is used.Those pilot lights, going all the time, are releasing combustion products all the time. Maybe it's time for some stove owners to upgrade to the units with igniters. Those leaky connections? Can you say fire hazard?
