60% of Americans live in dangerous areas

The American Cancer Research Organization's annual report on April 29 found that six out of 10 Americans must live in heavily polluted areas.

The atmospheric situation in 2009 is stimulating real processes to prevent air pollution in many parts of the country, but most major cities are still submerged in polluted air. Although the green development program of the United States is progressing, the air of many cities is still more polluted. The air condition report includes a nationwide air quality assessment that divides levels from A - F to each region across the country. The report ranks the most heavily polluted cities and countries due to three common types of pollution (ozone, smog, annual molecular pollution and 24-hour molecular pollution levels) and coins. Specific directions for 900 countries during the past decade.

'This is a step to awaken countries. We know that air pollution is a major threat to human health, 'said Stephen J. Nolan, president of the National Cancer Society. '60% of American residents are fighting to breathe polluted air, we need to transfer them to a separate room, how to monitor their lungs there to develop the pollution situation. how serious. '

The report found that air pollution is dangerous to health in most major cities, threatening people's ability to breathe and putting life at risk. Some of the sources that cause the most air pollution include power plants, diesel engines and boats running on the sea are also warming the earth. 'The more we study, the more urgent we feel to find ways to make the air more fresh,' Nolan said.

Many cities, such as Los Angeles, New York, Atlanta, Charlotte, Philadelphia, Washington, DC, and Baltimore, have experienced significant improvements in air quality in their cities over the past decade. People living in these areas actually still have to breathe more polluted air than the reported results in the 2008 Cancer Society report. Only one city - Fargo, ND leads among the areas with the cleanest air in the United States.

Ozone

Sixteen cities on the list of ozone pollution actually experiencing pollution are far more serious than reported. 58% of the US population in a health hazard due to ozone pollution is tested more stringent standards since March 2008.

The new standard indicates that ozone levels that are dangerous to humans are now more common and serious than we are warned.

The summary of the past 10 years has identified some good developments in the ozone layer in some cities, surprisingly in Los Angeles where it was previously found to be a heavily polluted place. In contrast, in the cities of Dallas-Ft. Worth and Las Vegas have much higher levels of ozone pollution than 10 years ago.The report also summarizes the EPA-based content to track trends .

Ozone is the fastest dispersing form of air pollution. When inhaled, ozone destroys the lungs and causes lung damage. The effects of ozone can cause immediate harms such as wheezing, dry cough and asthma attacks. And breathing ozone can shorten life .

'More than 175 million Americans live in polluted areas - more than 80 million people compared to last year's report,' commented Charles D. Connor, president and chief executive officer of the cancer association. American lung letter. 'We believe that new ozone standards are still not enough to protect human health - that's shared by research experts.'

Molecular pollution

The condition of air divides the provinces into levels of molecular pollution into both 24-hour and 1-year categories. Molecular pollution is a toxic mixture of diesel, chemicals and metals. Those are the most toxic contaminants that are spreading in the US environment. Breathing these pollutants can put you at risk of death, cardiovascular disease, and asthma.

One in six Americans lives in polluted areas. Up to 9 cities named in the list of 25 molecular polluted cities in the year have shown improvements in measuring methods, including the five cities reported the best annual level since the Association Cancer plans to monitor these pollutants: Pittsburgh, Cincinnati, Atlanta, York, Pa., And Lancaster, Pa. The level of molecular pollution has worsened in dozens of cities, including Bakersfield, Calif., Los Angeles and Houston.

On average, 3 out of 10 Americans living in contaminated areas suffer from hours to days (24 hours). Thirteen cities even have more heavy days of pollution than the old report. Eleven cities have improved steadily since the 2007 report.

Recent research has reaffirmed the severity and the tremendous impact on health caused by molecular and ozone pollution, as well as redefined the groups in danger. New data indicate that women within 50 years of age may be more severely affected by air pollution, diesel truck drivers and dock workers are forced to breathe this waste from work. may face a higher risk of lung cancer or other related diseases. California researchers have made estimates of the number of people who can die every year from air pollution in the area where they live.

'Science is very tight. We know that air pollution can destroy the lung function even of the healthiest people, 'said the head of the Medical Office at the American Cancer Society. "Air pollution increases asthma and is a direct cause of cardiovascular heart disease, making people live with vulnerable hearts and lungs throughout their lives."

Low-income people and ethnic minorities often face risks from more pollution. Pollution sources such as factories and atomic factories can be built very close to their homes. Many people who live near areas with congested traffic or have poor medical facilities also make them more vulnerable to attack due to illness. Ethnic minorities are often leading in the risk of asthma or diabetes, all of which are caused by environmental pollution.

'We need to commit to providing a safe enough atmosphere for the American population - that's a commitment from the US government 40 years ago when the US Congress passed a clean air agreement.' Connor commented. 'After four decades we still have a lot of work to do. Americans need to reduce the amount of emissions they are emitting like coal-fired energy plants and diesel-powered vessels. We need to repair old motor engines to make them cleaner and clean up ozone for our health. Americans must strongly apply laws to help us improve the nation's air quality. '

When the United States is facing challenges of air pollution, global warming and energy, the American Cancer Society warns more Congress, EPA and individuals to find solutions. France solves the 3 challenges mentioned above.Some steps have been taken, but it may be good for a problem, but it can make the air worse.

Americans can change themselves to improve air quality as quickly as possible, and also to change the climate: driving less, not burning wood or coal, using electricity economically. and encourage schools to use buses.
