The Effects Of Air Pollution

Air pollution is a major cause of disease and death in large cities, which can be prevented. Despite improvements to enhance air quality through the years, the San Joaquin Valley does not meet the requirements of federal and state health ozone levels and particulate pollutants. Ozone is particularly a problem during the summer because high temperatures "cook" chemicals with sunlight to produce smog. Particles, meanwhile, represent a problem during the fall and winter season, when the increase in vehicle emissions and investing layers prevent the spread of these contaminants. Contaminant particles with a size of 10 microns or less (PM10) are a mixture of soot, chemicals, dust, salt, dirt, metals, smoke and toxins. PM10 are very small, about one-seventh the width of a human hair. Although they are micro size, they are dangerous as they can penetrate the body's natural defenses and concentrate on the depth of the lungs. Exposure to high concentrations of these particles can cause heart attacks, increase the risk of lung cancer, worsening conditions such as asthma and bronchitis, and reduce the function of the lungs. PM10 also include the group of particles known as PM2.5 refined. The sources of air pollution and related poor health are in transportation, power generation, home, for example, and vary between cities and regions. Effective interventions can reduce air pollution related diseases and produce health benefits, example, sustainable transport, energy-efficient buildings
