Air Pollution in America

Since the first start of coal mining in the early 18 th century, the air pollution problem in the United States is intensifying. Today there are many sources of air pollution, researchers are looking for ways to solve the problem and its environmental impact.

Air pollution is the incorporation of chemicals, particles, biological substances and other substances into the atmosphere. This may happen naturally or as a result of technology. It is usually a combination of two

In the United States, the greatest source of air pollution is transport. According to CBS news, emissions from automobiles and other cars account for 60% of the country's carbon monoxide pollution, but emissions in most cities will be as high as 95%.

Naturally, the area with the most serious air pollution is the area around big cities. Due to urban congestion and heavy traffic, these areas maintain dangerous ozone levels throughout the year.

California has most air pollution cities, but measures are taken to ensure clean air for state residents. The most contaminated cities are as follows.

Most other states do not have as much as cities with air quality problems. Several other terribly polluted cities in the USA:

The US Congress passed the Atmospheric Remediation Act in 1963 to limit the amount of pollutants released into the atmosphere. Since then, several amendments to the bill have been made to strengthen the bill and to help make it more detailed. However, according to History.com, as of 2007, 46% of the country's population lived in a county experiencing unhealthy air pollution levels.

Clearly, the individual is responsible for protecting the environment. Everyone is willing to reduce the number of driving and traveling. Other possibilities are:

Everyone can do a lot to limit the amount of air pollution they produce. Adding small changes every month can bring about a cleaner environment for a long time. At a minimum, you can see that you are playing your part.

Although serious air pollution in North America and Western Europe is not rare now, many developed countries still have serious air quality problems. Over the past 50 years extensive environmental investigations have been conducted on the source and formation of air pollution. And as research results adopted policies and pollution control equipment, air pollution has been successfully managed. Advanced industrialized countries are faced with unique and constantly changing challenges related to air pollution. Therefore, "Environmental Science and Technology" and "Environmental Science and Technology Letter" summarized virtual issues that took up the latest trends in the following areas. They are particularly suitable for developed countries.

Ozone pollution - often referred to as smoke - is the center of air pollution problems in the United States. When the temperature is high, smoke tends to be generated, the air stagnates, and the dirty air does not go out of the prescribed place. Between 2014 and 2016, the number of days of unsafe ozone pollution increased significantly during the period assessed in the report, but the Earth experienced the hottest year in record. The federal government led by Trump Environment Protection Agency is trying to slow down the plan for air pollution control. Earlier this month, Mr. Trump signed the presidential decree requesting the US Environmental Protection Agency to change the federal environmental protection standards in order to reduce the "necessary barriers to new manufacturing and business expansion essential to economic growth" did.
