Landmark Study Reveals Gas Stove Emissions Boost Childhood Asthma

People who use gas or propane stoves in their homes are regularly exposed to harmful levels of nitrogen dioxide (NO2), a new study shows. The household appliances emit pollutants that can be linked to approximately 200,000 current cases of childhood asthma, with 25 percent of those cases tied to nitrogen dioxide alone. The study, published Friday in Science Advances, represents the first time researchers have quantified the link between gas stoves and asthma from NO2 exposures inside homes. “I didn’t expect to see pollutant concentrations breach health benchmarks in bedrooms within an hour of gas stove use, and stay there for hours after the stove is turned off,” Rob Jackson, a professor at Stanford University and the lead scientist on the study, said in a statement.

The Nitrogen Problem In Agriculture

The nitrogen problem in Agriculture is a problem created by synthetic nitrogen fertilizers made from fossil fuels. Nitrogen fertilizers contribute to atmospheric pollution and climate change in the manufacture and the use of fertilizers. The manufacture of synthetic fertilizer is highly energy intensive. One kg of nitrogen fertilizer requires the energy equivalent of 2 liters of diesel. Energy used during fertilizer manufacture was equivalent to 191 billion liters of diesel in 2000 and is projected to rise to 277 billion in 2030. This is a major contributor to climate change, yet largely ignored. One kilogram of phosphate fertilizer requires half a liter of diesel. Nitrogen fertilizers also emit a greenhouse gas, N2O, which is 300 times more destabilizing for the Climate System than CO2.
