No pandemic plunge in Hamilton air pollution, report shows

Hamiltonians didn't breathe loads simpler in 2020 regardless of a pandemic lockdown that slowed industry and minimize automotive site visitors.

The newest annual report from Clear Air Hamilton, which tracks air air pollution within the metropolis, continues to indicate an total pattern of enchancment for the reason that Nineties.

However monitoring within the first 12 months of the COVID-19 pandemic didn't reveal a dramatic drop in air air pollution. Mud and sulphur dioxide ranges fell barely downtown — however industrial areas noticed ranges of downside pollution edge upward.

“We didn’t see that (dramatic drop), surprisingly,” mentioned Clear Air Hamilton chair Bruce Newbold. He famous there's ongoing analysis into lockdowns and air pollution, however native outcomes should not but accessible.

Against this, analysis by The Atmospheric Fund suggests greenhouse fuel emissions in Hamilton plunged in 2020 — seemingly briefly — as a result of manufacturing slowed and fewer autos have been on the street throughout COVID restrictions.

That drop in carbon emissions was not mirrored by notably plunging ranges of air pollution, the report exhibits.

Whereas downtown air pollution fell barely, there was an “uptick” for pollution like sulphur dioxide, benzo(a)pyrene and nitrogen dioxide in industrial areas.

Newbold careworn the long-term pattern remains to be “excellent news” for Hamilton. That features a long-term “important” drop within the city-wide degree of cancer-causing chemical substances like benzene and lung-penetrating mud, for instance.

However these ranges are nonetheless excessive in comparison with different cities, mentioned Setting Hamilton head Lynda Lukasik.

So whereas ranges of inhalable mud have dropped steadily, they're nonetheless greater than these in comparator cities like Toronto, Sarnia, Kitchener and Windsor. Benzene and benzo(a)pyrene ranges are additionally falling — however stay greater than provincial pointers.

Lukasik mentioned she can be anxious to see pollutant ranges edging up in industrial areas. “There are residents dwelling very close to a few of these industrial areas,” she mentioned.

That’s a part of the explanation town has teamed up with researchers and Setting Hamilton to arrange “hyper-local” air high quality screens this 12 months throughout town, however specifically in near-industry neighbourhoods and people with greater ranges of poverty or new immigrants.
