Use reduction highway salt to strengthen Ontario ecosystem, urges WWF

As Toronto deals with vacillating winter weather, environmental advocates contend extreme highway salt is harming Ontario wildlife — and they’re titillate people to use less.

Salt used to warp icy roads and sidewalks can finish adult flowing into rivers, lakes and soil, formulating dangerously tainted environments for some freshwater plants and animals.

In certain areas during winter, “some of a rivers will have salt as high as oceans,” said Elizabeth Hendriks, vice-president of freshwater with a World Wildlife Fund Canada. 

Some frog and salamander class can’t multiply in ponds with high salt volumes, pronounced Environment Canada scientist Patricia Gillis, while rivers can turn salty enough to kill immature freshwater mussels.

“Impacts to even a few class can outcome a whole ecosystem,” pronounced Gillis in an email.

Many people tend to use too many salt, pronounced Hendriks, who previously pronounced a tiny tablet bottle value of highway salt is all we need to warp a city path slab.

“People tend to churn highway salt on a ice,” pronounced Angela Murphy, manager with Ryerson Urban Water.

“It’s unequivocally not necessary.”

In a commander program last year, Murphy says they used 6 fewer tonnes of salt by spraying a rebate of salt and H2O called brine in 4 exam locations before to sleet and frozen rain.

“It was only as effective,” pronounced Murphy, who says Ryerson done a brine in-house and it did not harm open safety. 

“There was no boost in liability, no boost in complaints … there’s unequivocally no need for people to request so many highway salt.”

Their group is scaling adult a plan this winter, Murphy said, and study a impact of using brine in place of highway salt in certain city areas.

City uses 130,000 tonnes of highway salt

The city of Toronto uses some-more than 130,000 tonnes of highway salt any winter, as good as brine and some salt alternatives.

However, City of Toronto orator Eric Holmes pronounced salt is a many cost effective and fit approach to transparent ice from roadways.

The city has to balance negative environmental impacts, he said, though their focus is on open safety.

The city implemented a salt government plan in 2002 to revoke salt use, Holmes said, that revoke salt use 15 per cent in a a initial 15 years.

They also put down salt brine before a storm, he said, and city trucks use automated apparatus to establish where to widespread salt formed on highway temperature.

Last year they also used beet extract a few times, Holmes said. But while it works in colder temperatures than highway salt, he said, beet extract is harder to get and some-more expensive.

Although reserve is critical, Hendriks said both open roadways and private properties minister to over-salting in Ontario’s lakes and rivers.

She points to information programs like “Smart About Salt,” where contractors and skill owners can learn ways to revoke their salt usage.

“Everything we do on a land feeds into a stream complement and into [Lake Ontario],” Hendriks said.

“What we do on a land and on a roads matters.”
