Following are the results of the Ministry of the Environment's 1986 air quality report for Northwestern Ontario. The report presents results from air quality monitoring, vege- tation and soil surveys and snow sampling in several communities across the region. Cadium levels The Ontario Ministry of Natural Resources is again warn- ing hunters not to eat the kidneys and liver from moose, or the kid- neys from deer because of high cadmium levels. Cadmium is a heavy metal which can be toxic at high levels of exposure. It occurs naturally at low lev- els in the ecosystem but may reach higher levels in some areas. Cadmium accumulates in the kidneys and liver of some longer- living species such as moose and white-tailed deer. Experiments have shown that very high concentrations of cad- mium can cause kidney and liver damage in mammals. "Cadmium levels in moose and deer are lowest in southwest- ern Ontario and highest in central Ontario," Natural Resources Minister Vincent Kerrio said. "The reason for these regional differences is not yet known, but we're conducting further studies to find out why, and how cadmi- um gets into the ecosystem." The World Health Organization has set a limit of 0.5 milligrams per week for human consumption of cadmium. Extensive testing in Ontario has established that 300 grams (11 ounces) of liver from deer fawns may be consumed per weck, according to WHO guide- lines. The ministry recommends that liver from older deer should not be eaten but that other moose and deer meat are safe for consump- tion. Ministry researchers first dis- covered high cadmium levels in moose kidneys in 1984. Since then, with the co-opera- tion of Ontario hunters, more than 700 moose and 950 white-tailed deer have been tested across the province. One trend that's been noted is that cadmium levels are generally higher in moose that in deer. The ministry is involved in various co-operative studies with other government agencies and universities to determine the path- ways of cadmium in the ecosys- tem.

Emphasis is placed on moni- toring progress in pollution con- trol programs carried out under ministry control orders for the pulp and paper industry. These control programs result- ed in significant improvement in air quality in several communities in the late '70s and early '80s. In 1986, air quality in several areas in the region showed little change from 1985. In other com- munities, there were minor improvements or declines. New control orders or other abatement programs are being negotiated with industry to address situations where addition- al pollution controls are required. 10 of 11 exceed Ten of 11 Northwestern Ontario communities monitored experienced exceedences of provincial air quality guidelines in 1986, the Ministry of the Environment report states. It indicates that air quality has generally improved in Dryden, remained unchanged in Atikokan, Balmertown, Kenora, Longlac, Red Rock, Terrace Bay and Thunder Bay, and worsened in Fort Frances and Marathon. All communities except Atikokan recorded provincial air quality exceedences. TRS (Total Reduced Sulphur) concentrations near the James River-Marathon Ltd. mill in Marathon exceeded the provincial guideline in 115 hours out of 7,427 hours tested. This is up from 83 hourly exceedences in 1985. Process changes are currently underway to control this problem. \ \ ) \ \.

To achieve compliance with the TRS guideline by June 1989, as required in the current control order, process improvements will be implemented at the mill to reduce odour emissions. Past surveys have shown that the Kimberly-Clark mill in Terrace Bay does not contribute to fallout of particulate matter in the adjoining townsite. Therefore, the ministry's moni- toring program is directed toward measurement of odour levels in the townsite and at three points where an effluent ditch from the mill crosses the trans-Canada Highway (work is now underway to divert this ditch from beside the highway). Odour levels . Average sulphation rates in 1986 were similar to results for preceding years. TRS data showed that, during 1986, there were 72 hourly read: ings above the provincial guide- line of 27 ppb at the ministry's monitoring site. The maximum hourly average was 155 ppb. The 1986 results were similar to those for 1985. TRS data for the ministry's monitor are continuously teleme- tered to the mill. Under a new control order, Kimberly-Clark will be putting process improvements in place to reduce odour emissions. The control order calls for compliance with the TRS guide- line by June, 1989. 463095 L) & * v. ee imberty - RA lark of | onada Lid' % ns ee \y WS to "es TERRACE BAY eC © L S-~& | booms ; Superior pe ES r..
