Sudburys' "Roast Beds"
- Roasting yards were an early method of separating valuable minerals from rock. The first roast yard, where crushed ore from pits was piled on beds of cordwood, was built in Dec. 1886. Between 1890 and 1930, 28 million tonnes of ore was smelted primarily in the open. After 1920, ore was mechanically smelted indoors. Until the process stopped in 1929, “they released about 10 million tonnes of sulphur dioxide at ground level, killing plants and acidifying soils...open-bed roasting was a cheap but ultimately inefficient method, as it allowed some of the nickel and copper to be washed into the soil by rains.” In 1916 one former resident of the community near the O’Donnell roast yard said there were days when “I could not see my hand in front of my face.”I think the claim that we are dealing with is that it "is" happening...
I know, I know, "Well, it depends on the meaning of "is"."
That is interesting history from 80 years ago -- I believe that Thomas Mulcair and Dennis were referring to "today".
To put this in context, this is not argument that jobs in resource extraction are bad. Maybe some politicians need to be a rig pig in the oil fields for a while and grunt labor on the oil sands. They might learn something.
Reports on Sudbury:
See here: Helath Risk Conclusions:
The main conclusions from the detailed human health risk assessment for the Greater Sudbury study area are as follows (And as I recall the results are/were unexpected):
1. Based on current conditions in the Sudbury area, the study predicted little risk of health effects on Sudbury area residents associated with metals in thefwiw
2. There were no unacceptable health risks predicted for exposure to four of the six Chemicals of Concern studied: arsenic, copper, cobalt, and selenium.
3. The risk calculated for typical exposures to lead in the environment throughout the Greater Sudbury area are within acceptable benchmarks for protection of
human health. However, levels of lead in some soil samples indicate a potential risk of health effects for young children in Copper Cliff , Coniston, Falconbridge and Sudbury Centre.
• Lead levels in soils and dust in the Sudbury area are similar to levels in other older urban communities in Ontario.
4. The study calculated a risk of respiratory inflammation from lifetime exposures (70 years) to airborne nickel in two areas: Copper Cliff and the western portion
of Sudbury Centre.
• Respiratory inflammation has been linked to the promotion of cancer caused by other agents;
• Based on the conservative assumptions and approaches used in this risk assessment, it is unlikely that any additional respiratory cancers will result from nickel exposure over the 70-year lifespan considered in the risk assessment;
• Health risks related to nickel inhalation were not identified in the other communities of interest.
5. Anglers, hunters and First Nations people who may consume more local and wild game are at no greater risk of health effects due to metals in the environment than the general population.
