"On hot days, they contribute to ground level ozone, which creates problems for those who have difficulâ€" ty breathing. If air quality is improved, we can reduce the high number of hospital and emergency room visits that now occur," he says. Here are some interesting facts: * The total number of cars on ‘ Toronto streets increased 36% between 1970 and 1987. Pollutants from car exhaust contain carbon monoxide, nitrogen oxides, hydrocarâ€" bons, and carbon dioxide. * Gasoline is the largest source of air contamination. It contributes to poor air and soil quality. Reducing car mileage in favor of phoning, wriling, walking, cychng will reduce air polluâ€" tion. * These holes increase exposure of the sun‘s harmful ultraâ€"violet rays that can cause skin cancer, eye cataracts, and diseases of the immune system. * A hot sun and strong breeze can increase airborne allergens. Rain can clear the air, but it also increases the incidence of mold. Sea air is the most pollen free. Ground level ozone is a major (See ‘What you .. .‘ page 12) * Located 15 to 35 kilometres above earth, in the atmosphere, is the ozone layer. It filters out the sun‘s harmful ultraâ€"violet rays. Chemicals such as Chlorofluoroâ€"carbons (CFCs), halons, and methyl chloroform are thinning the ozone layer, causing holes in places. Hazy smog cause for breathing difficulties Now, there‘s help for people with breathing difficulties. The Halton Lung Association is offering proâ€" grams to help people with respiratory conditions breathe easier. The federal and provincial enviâ€" ronment department issues an Air Quality Index and weather advisories and reports this information to the media, so that people with breathing difficulties know when they sh@uld alter their activities. "Last summer was a great one for good outdoor air quality," says Fred Conway of Environment Canada‘s Atmospheric Issues Division, Ontario Climate Centre. Drivers will be able to play a part in improving air quality. "‘People with breathing difficulties can revise their activities on highâ€" smog days," says Dr. John Kirby, respirologist at Oakville Trafalgar Memorial Hospital and president of the Halton Lung Association. "It may be best to stay indoors when outdoor air quality is poor." "This summer may be closer to average, with about five smog adviâ€" sories over the summer," he says. "Exhaust fumes from vehicles are major contributors to smog," says Kirby. The quality of the air you breathe is probably the last thing on your mind as you throw open the windows and doors this summer. But summer‘s hot, hazy days can bring smog â€" and that contributes to breathing difficulâ€" ties for thousands of Canadians with lung disease such as asthma, emphyâ€" sema, and bronchitis.
