Cooking Sunday roast causes indoor pollution ‘worse than Delhi’

Fine soot and tiny organic particles from gas flames, vegetables, oils and fat combined to send harmful PM2.5 particulates in the house to levels 13 times higher than those measured in the air in central London. Peak indoor pollution lasted for about an hour.

Hold your breath: U of T researchers investigate the effects of nitrous acid on indoor air quality

While conversations surrounding air pollution have largely centred on outdoor pollution, indoor air pollution also poses a threat to public health. A study led by Douglas Collins, former postdoctoral fellow in the Abbatt Group in the U of T Department of Chemistry, explored the effects of nitrous acid on indoor air quality.

HOMEChem gives chemistry student inside look at air quality

Erin Katz, a fifth-year Drexel University Chemistry program senior, found herself cooking two Thanksgiving dinners in a manufactured home in Texas in June; all for science. Katz was participating in a large and unique field experiment as part of the project HOMEChem, which stands for House Observations of Microbial and Environmental Chemistry. The study marks a landmark undertaking in the relatively new field of indoor air chemistry and related studies.

Professor Jon Abbatt: Looking inside the chemistry of our indoor spaces

“It has been known for a long time that the concentrations of outdoor pollutants are correlated to negative health outcomes and as a result outdoor air studies have received a lot of attention in the past,” says Abbatt. “But interestingly, concentrations of most molecules that we breathe are considerably higher indoors than outdoors.”

Are You ‘Safely Indoors’?

There is a growing realisation that most air pollutants found inside originate from indoor items or activities. A number of studies have shown concentrations of some molecules in air are frequently two to five times higher indoors than typical outdoor concentrations. Combustion sources – such as gas hobs, wood-burning stoves and candles – are big culprits.

Large scale experiment probes chemistry inside our homes

Funding for indoor research is hard to obtain, in part thanks to the misconception that air pollution is solely an outdoor problem. Only a small number of indoor field measurements have been collected previously, usually looking at a few chemicals with a couple of instruments.

Indoor Chemistry: An Emerging Science

In a modest ranch house on the outskirts of Austin, Texas, Shan Zhou prepares a basic stir fry recipe. She heats oil to a smoking hot temperature and then stirs in vegetables, which sear in the oil and send up a plume of steam. She pours in packaged stir fry sauce, which sizzles in the wok. Shan wasn’t cooking lunch. She is a researcher for a sophisticated, first-of-its-kind field study of pollutants in indoor air.
