(Canada) 1990 Toxic flames Burning tires spew poisons into the air Driving near his farm 100 km southwest of Toronto, Ontario Treasurer Robert Nixon said he worried about the danger of fire when he passed the 15 million used tires in a single, city-block-sized heap at the Tyre King Tyre Recycling Ltd. dump near Hagersville. Despite the company's name, owner Edward Straza did not recycle tires but charged people to dump them on his lot until he could find a facility to dispose of them. Last year, when Nixon imposed a $5 tax on the sale of each new tire in order to raise funds for recycling facilities, he singled out Tyre King as "an environmental menace." That forecast became reality in the early morning of Feb. 12, when the tires caught fire, sending clouds of thick, black, toxic smoke into the air. The blaze, which officials said was deliberately set, resisted about 180 firefighters' efforts all week and forced hundreds of area residents from their homes. Experts declared the fire a major environmental disaster and said that it could continue to burn slowly for months. That is because the tires' major component is a petroleum-based substance that, once alight, is almost impossible to extinguish. Fumes that its flames emit contain such chemicals as benzene, known to cause leukemia in tested animals, and toluene, which can damage the kidneys and liver. In addition, as the tires melt, they release an oily liquid that could seep into soil and contaminate groundwater. Said Gerard Coffey of the Toronto environmental group Pollution Probe: "It's going to get into water and under pastureland." The dump, Coffey added, "was not meant to hold toxic waste. But that's what it's turned into." One likely effect of the fire will be to force officials to confront with greater urgency the issue of tire recycling. Said Ontario environment ministry spokesman John Steele: "If anything good can be said about the fire, it's that there will probably be more said about recycling in the future." Experts say that Ontario's rate of tire disposal, at about 11 million a year, far outstrips the province's recycling capacity. Nixon said that his government expects to raise about $40 million a year from the tire tax, but so far the province's four recycling firms, which break tires down for use in such products as road surfaces, have received only $1.1 million. Said Coffey: "The way recycling is structured now, we need storage facilities for stuff like tires that can't be recycled immediately." In light of last week's events at Hagersville, such storage sites will clearly have to be less vulnerable than the Tyre King dump.
