From job creation to economic spin-off, there could be plenty of benefits if the City of Greater Sudbury is selected as the site for Noront’s proposed ferrochrome smelter. But one group is again.

    Sudbury, officially Greater Sudbury (French: Grand-Sudbury), is a city in Ontario, is the largest city in Northern Ontario by population, with a population of , at the Canadian Census. By land area, it is the largest in Ontario and the fifth largest in is administratively a Unitary authority, and thus not part of any district, county, or regional y: Canada.   Noxious gas released from Sudbury smelter A nitrogen dioxide leak at Vale’s Copper Cliff smelter caused some tense moments in Sudbury. The noxious gas (NOx) was released from the company’s acid plant during a maintenance shutdown, Aug.

The Sudbury Basin of Ontario, Canada, contains one of the world's major ore deposits of nickel and copper. However, in comparison with many smelting operations in the United States and Europe, smelting in the Sudbury region is a relatively recent develop-ment.

Aquatic ecosystems in a 17, km2 area around Sudbury, Ontario, Canada, have been affected by the atmospheric deposition of pollutants from nearly a century of operations at the Sudbury area metal smelters.

Effects were most severe in the lakes closest to the smelters which historically received very high deposition of both acid and metal particulates. After smelter emissions were greatly Cited by: Long-term effects of smelter pollution at Sudbury, Ontario, on forest community composition Article in Canadian Journal of Botany 58(19) January with Reads How we measure 'reads'.

More t lakes in Ontario were acidified to the point of ecosystem damage, 7, of them within Sudbury’s immediate vicinity.

“Lakes within the. Over 7, lakes around Sudbury, Ontario, Canada were acidified by S deposition associated with emissions from the Sudbury metal smelters and more distant S sources.

Air pollution controls have led to widespread changes in damaged Sudbury lakes, including increased pH and decreased concentrations of SO 4, metals and base cations. While chemical Cited by: Smelter emissions in the Sudbury area were one of the world's largest point sources of SO2 emissions during the s, accompanied by thousands of tons of emitted metal particles [24].

Metal. The Inco Superstack in Sudbury, Ontario, with a height of metres (1, ft), is the tallest chimney in Canada and the Western hemisphere, and the second tallest freestanding chimney in the world after the GRES-2 Power Station in is also the second tallest freestanding structure of any type in Canada, behind the CN Tower but ahead of First Canadian Place.

Of these, smelter emissions typically comprise the largest fraction; insmelters accounted for 44% of provincial emissions (Environment Ontario, ). At the time, prior to the construction of the Inco Superstack, there was very little done to mitigate the implications of air pollutants on the environment.

The Ontario government is dramatically reducing the limits for industrial sulphur dioxide emissions, but the environment minister says Sudbury mining companies won't have to hit those : Erik White. Lakes in a large area of northeastern Ontario have been severely affected by the atmospheric deposition of contaminants originating from the Sudbury smelter emissions.

The E'alconbridge smelter is about 14 miles NE. of that at Copper Cliff. Lakes located closest to Sudbury (Ramsey and MacFarlane) have higher particulate arsenic than the lakes (such as Nelson and Windy) further re- moved from the point source.

By comparison, the arsenic concentrations in suspended particulates from Bass, Horseshoe and Rankin Lakes average about ug g~' (see Table 2).Cited by: Government regulations resulted in major reductions in toxic emissions from the three Sudbury smelters.

One smelter was closed, while technological and process changes were made to the INCO/Vale and Falconbridge/Glencore smelters resulting in dramatic decreases in sulphur dioxide emissions. @article{osti_, title = {Deposition and chemistry of pollutant metals in lakes around the smelters at Sudbury, Ontario}, author = {Nriagu, J O and Wong, H K.T.

Perhaps most famously, the landscape of Sudbury has been said to be comparable to the landscape present on the moon.
