Coastal residents may be worried about exposure to forever chemicals from sea spray during hot summer months, but York University researchers found there was little evidence of per- and polyfluoroalkyl substances (PFAS) contamination from marine aerosols, a finding that surprised them.
A new study out of York University has found that the amount of atmospheric trifluoroacetic acid (TFA), the tiniest forever chemical, significantly declined in Toronto during COVID in 2020, which researchers say is good news for the world’s ability to mitigate it in the future.
Several students are participating in SWAPIT, a large winter air quality study, run by Environment and Climate Change Canada Who would imagine a bright, sunny winter day could have higher concentrations of some air pollutants than a hazy summer day? Not only is it uncommon for people to consider air quality during the coldest months […]
A large percentage of PFAS are not being accounted for in the air, while PFAAs have accumulated in sometimes surprising amounts over 50 years in the high Arctic.
As Toronto gets hotter, muggier and wildfire smoke increasingly wafts through the atmosphere, researchers at York University are leading a team of atmospheric scientists in testing the city’s air pollution from their rooftop Air Quality Research Station for six weeks this summer.
TORONTO, May 14, 2020 – An international environmental agreement to regulate the use of chemicals depleting the ozone layer may have inadvertently allowed higher levels of other harmful chemicals to flourish, new research co-led by York University and Environment and Climate Change Canada has found. The 1987 Montreal Protocol on Substances that Deplete the Ozone […]
