A hidden source of air pollution? Your daily household tasks

The previously underexplored relationship between households and air quality drew focus today at the 2019 AAAS Annual Meeting in Washington, D.C., where researchers from CU Boulder’s Cooperative Institute for Research in Environmental Sciences (CIRES) and the university’s Department of Mechanical Engineering presented their recent findings during a panel discussion.

Why your roast dinner could be killing you: Indoor pollution from cooking as bad as in city centres, say scientists

The world’s largest gathering of scientists heard that pollutants from roasting include PM2.5 particulates, which are particularly harmful because they are small enough to embed deep into the lungs and, in some cases, even enter the bloodstream.

Toast is more toxic than traffic fumes

The dangers of such indoor pollution emerged from a study by the University of Texas at Austin which built a replica of a typical three-bedroom home equipped with dozens of monitors to assess how air quality changed during everyday activities such as cooking and cleaning.

Household Chemicals Pose Health Hazards

Materials in our homes like vinyl flooring and activities as common as cooking dinner can pollute indoor and outside air and cause detrimental health impacts, according to new research shared at a Feb. 17 news briefing at the 2019 AAAS Annual Meeting.

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.
