A recent study has raised concerns about the health risks associated with gas and propane stoves as it can significantly increase indoor air pollution levels of nitrogen dioxide (NO2).
About
The study found that homes with gas or propane stoves expose residents to an estimated 4 parts per billion (ppb) increase in nitrogen dioxide (NO2)on average over a year.
Nitrogen dioxide is a reddish-brown, pungent, acidic gas that is corrosive and strongly oxidizing.
Sources of nitrogen dioxide (NO2)
Anthropogenic activities: The main source of nitrogen dioxide resulting from human activities is the combustion of fossil fuels (coal, gas and oil) especially fuel used in cars.
It is also produced from making nitric acid, welding and using explosives, refining of petrol and metals, commercial manufacturing, and food manufacturing.
Natural sources of other nitrogen oxides include volcanoes and bacteria.
Effects of nitrogen dioxide (NO2)
Health: Nitrogen dioxide can decrease the lungs’ defenses against bacteria making them more susceptible to infections. It can also aggravate asthma.
Ecosystem: Nitrogen dioxide is toxic to plants in short-term concentrations of 120 µg/m3. It reduces plant growth.
Along with sulfur dioxide, nitrogen dioxide can cause acid rain.
Nitrogen dioxide can form secondary particles called nitrates that cause haze and reduce visibility.
