its urbanization step in the future. Three problems are investigated: air pollution, water quality and soil contamination. These ones are significant in our lives as they can affect our organs and thus influences our health directly. Through urbanization, the most common view is the establishment of factories. Most of these factories are located in heavy industrial areas of the cities. It is easy to hypotheses that air quality has become worse in Shanghai since it started urbanization in the 1980s

many different forms such as water, air, noise, and light, all of which affect our society in different ways. The focus of my essay is specifically about air pollution and the effect it has on our society, as well as ways of preventing it from hurting future generations. Air pollution is most commonly caused by the burning of fossil fuels, agricultural activities, and exhaust from factories and industries. Many governments have already implemented air quality standards to protect against health and

Historically (pre-1892), the agrarian landscape was conducive to clean air; a time void of pollutants; however, with the advent of the industrial revolution, air quality was forever changed. Interestingly, two of today’s leading contributors of emissions are the result of two significant man-made events dating back to 1892 and 1893, which first began polluting the air. First came the emergence of factories with their emission billowing smokestacks (Davis & Henderson, 2011), which was followed by

Recently, China is experiencing a rapid urbanization which results from tremendous economic growth. As a result, large numbers of cities are suffering from air pollution. Almost two-thirds of cities in china have not met the ambient air quality standard which is applied to urban residential areas. According to Hao& Wang (2005), it is particulate matters(PM) rather than SO2 that is the major pollution which reflecting the pollution source is transformed from coal burning to several sources of pollution

Clean Air Act Clean Air Act, 42 U.S.C. § 7401 et seq.        -- Enforced by US EPA -- By the end of this lecture you should be able to describe: * The race to laxity * What NAAQS means. * The federal government’s role in cooperative federalism * 7 criteria pollutants * A hazardous pollutant under the CAA * Non-attainment area * Emissions trading programs * Noise pollution under the CAA * The four Class I areas designated by the State of Florida

Statement (EIS) of a proposed construction project of a new recycling center in a rural area. The proposed project is to be built in a nonattainment area. The EIS will address land-use and development, social and neighborhood effects, economic factors, air quality, noise, and water resources as it relates to the proposed project. Included in the process will be three alternatives as well as a no build alternative. The Environmental Impact Statement will provide a detailed scoping of the project along with

The Battle Over Air Quality Standards Proposed by: The United States Environmental Protection Agency (EPA) The American Lung Association (ALA) The Natural Resources Defense Council (NRDC) The Sierra Club Consumer and Other Environmental Organizations Opposed by : The Air Quality Standards Coalition (It consists of approximately 600 industrial companies and interest groups) Automobile manufacturers The American Trucking Association, The National Association of Manufacturers The Chemical

been projected as a developed and liberalized nation when it is compared to other countries. China, for instance, is a very strict and still developing nation. However, that is not the case. Environmentally, the USA and China both undergo horrible air pollution that affects not only the land, but the people as well. Since both nations make up the majority of the world’s population, it is important to focus on the health and living conditions of all inhabitants. The United States is largely diverse

urban sprawl and decreased air quality (Fairfax County, 2014). With rapid growth in the county, the transportation sectors have expanded increasing the amount of mobile sources for air pollution from both within the county and from outside the county. Air quality in Fairfax County has been improving; however, the county and the region have yet to meet federal air quality standards for 8-hour ozone and particle matter. 2.
