If you ride a bike to work in a city you might want to check out a study from Trinity College Dublin. The essence of the findings is that while cycling you're breathing in dangerous pollutants and doing yourself considerable harm.
It is not simply the fumes from the exhausts of cars and trucks, either, but also the pollutants coming off the brakes and tires of vehicles. Further, other studies have concluded cycling in the city is doing more harm than good, a 2011 report from the U.K. found cyclist breathed in more harmful black soot or 'black carbon', linked to a higher risk of heart attack and respiratory problems. Thirty-two cyclists who regularly ride in the city were used in the study. "These (findings) indicate that exercise while commuting has an influence on inhaled particulate matter, associated with acute declines in heart rate variability," the study said. "Especially in pedestrians and cyclists." Study lead author Marguerite Nyhan said that if you cycle through the city regularly you would be advised to find less-traveled routes. There have been studies suggesting that masks, if fit properly, can reduce harm from breathing in pollutants while cycling.
