Particle pollution, also called particulate matter or PM, is a mixture of solids and liquid droplets floating in the air. Some particles are released directly from a specific source, while others form in complicated chemical reactions in the atmosphere. Particles come in a wide range of sizes. and secondary particulate matter standards were appropriate. ¸ On J , EPA issued an advanced notice of proposed rulemaking on the ozone and particulate matter standards. The Agency announced that the schedule for both reviews was the same, explained the linkages between these. Ozone Fine Particulate Matter (PM ) The key contributors to smog and poor air quality in Simcoe Muskoka are ozone (O 3) and fine particulate matter (PM ). Ozone. Ground-level ozone is formed when pollutants from vehicle exhaust emissions react in sunlight. Ozone can accumulate in suburban and rural areas (like Simcoe Muskoka) because the. Like Particulate Matter, ground-level ozone is also currently considered a “criteria air pollutant.” The U.S. Environmental Protection Agency (EPA) has identified ozone as a pollutant that causes significant health (respiratory) and environmental (visibility and vegetation damage) effects. The EPA has currently established NAAQS for ozone.
1. Introduction. Ozone (O 3) is a well-known atmospheric air pollutant, a so-called “photochemical oxidant”.Although the mean concentration of O 3 in Japan has generally remained unchanged in recent years, it has increased in urban areas with large populations in the past two years. The concentration of O 3 in many urban areas in the U.S., including New York City, has been shown to exceed Cited by: 1. the EPA's restrictions on particulate matter are not supported by evidence This isn't completely true, there is evidence showing particulate matter is harmful for humans. The bulk of this evidence is in the form of Epidemiology studies, looking at human health statistics and comparing to their exposure to PM. Particulate Matter (PM) Air Quality Standards The Clean Air Act requires EPA to set national air quality standards for particulate matter and five other pollutants considered harmful to public health and the environment (the other pollutants are ozone, nitrogen oxides, carbon monoxide, sulfur dioxide and lead). What is Ozone? l Ozone: “Good up high, bad nearby.” l Ground-level ozone results from chemical reaction of nitrogen oxides and hydrocarbons in presence of sunlight. l At ground-level, ozone is principal component of smog and one of 6 “criteria pollutants” for which EPA sets NAAQS. l In stratosphere, ozone occurs naturally andFile Size: KB.
