SMOG AND POLLUTION IN L.A Students: • Lorena Castillejo • Emanuel Manrique • Jose Cashipa INTRODUCCION Smog is air pollution that reduces visibility. The term "smog" was first used in the early 1900s to describe a mix of smoke and fog. The smoke usually came from burning coal. Smog was common in industrial areas, and remains a familiar sight in some cities today. Los Angeles is a city notorious for its smog, a combination of particle and ozone pollution. The prevalence of these pollutants result from many factors, including the burning of fossil fuels, especially by vehicles, ships, planes and manufacturing, as well as wildfires. Los Angeles is not the only place with an air pollution problem. In many European cities, a rise in diesel vehicles has contributed to high levels of air pollution. Developing countries like India and China continue to experience high levels of air pollution as a result of rapid industrial growth and weak regulation. CAUSES Smog is formed by mixing air with pollutants and exhaust gases resulting from human activities. The factors which are responsible for this include factories, an increasing number of cars. pollution is caused by things such as factories, power plants, cars, airplanes, chemicals, fumes from spray cans, and methane gas from landfills, but the ways that humans caused the most air pollution is by burning fossil fuels. Effects it causes serious health problems ranging from minor irritations, coughing, and wheezing, to asthma attacks. Breathing in particle pollution can also contribute to heart attacks, strokes, and even premature death. Solutions Palazo Italia – Milan Smog-Eating Cement Manuel Gea González Hospital – Mexico
