Cooking Sunday Roast Causes Indoor Pollution 'Worse Than Delhi' (theguardian.com)
pgmrdlm writes: Cooking a Sunday roast can drive indoor air pollution far above the levels found in the most polluted cities on Earth, scientists have said. Researchers found that roasting meat and vegetables, and using a gas hob, released a surge of fine particles that could make household air dirtier than that in Delhi. Fine soot and tiny organic particles from gas flames, vegetables, oils and fat combined to send harmful PM2.5 particulates in the house to levels 13 times higher than those measured in the air in central London. Peak indoor pollution lasted for about an hour.
"We were all surprised at the overall levels of particulate matter in the house," said Marina Vance, who led the research at the University of Colorado in Boulder. She advised people to open windows and use extractor hoods if possible to ventilate the home while cooking. PM2.5s are particles that are smaller than 2.5 micrometres across. They are small enough to be inhaled deep into the lungs where they exacerbate respiratory disorders and cardiovascular disease. Smaller particles can spread from the lungs into the bloodstream where they build up in the liver, heart and even the brain, where they may contribute to depression and other mental health issues.

Oh, I see. So the comforting smells of food cooking is now a no-no, is that it? No wonder so many people are depressed: "Everything that makes you feel comfy and safe is BAD FOR YOU AND WILL KILL YOU!". What's next? The smell of fresh bread baking gives you heart disease? How fucking depressing.
