 Asian industrialization accelerates pollution of American air? Chinese scientist real hammer refute


The National Environmental Protection Agency (National Environmental Protection Agency) has always believed that the United States emission of nitrogen oxides has continued to decline over a decade, but the international research team led by Professor Jiang Zhe, the University of Science & Technology Chinas School of earth and space science at the University of Science & Technology China, has found that the decline in nitrogen oxide emissions in the United States has decreased significantly since 2011. Slowing down proves that the change of air quality in the United States is mainly led by the change of pollutant emissions in the United States. Green is the research teams data based on satellite images, and purple is the EPAs data. At present, the research has been published in the PNAS, the international comprehensive academic journal, and was first reported by the Losangeles times the Washington Post, the guardian, the daily mail, and other mainstream media. Losangeles times pointed out: photochemical smog related pollutants emissions slowed down significantly slowed down...... This finding explains why official data show that pollutant emissions continue to decline, but air quality has not been improved accordingly. NOx is an important precondition for haze and ozone. The National Environmental Protection Agency (EPA) has always believed that the nitrogen oxide emissions in the United States continued to decline rapidly between 2005 and 2015. Based on this judgment, the national environmental protection agency of the United States revised the national air quality standards in 2015 and lowered the acceptable maximum ozone concentration. The above study shows that the US believes that the reduction rate of NOx emissions has slowed considerably since 2011, and this trend is consistent with the satellite remote sensing and ground station observation data. Jiang Zhe told the science and technology daily, we used satellite remote sensing and ground station observation data from 2011 to 2015 to analyze the data. The results showed that the decline rate of nitrogen oxides and carbon monoxide emissions in the United States slowed considerably. Data show that not only the United States has slowed down the scope of nitrogen oxides reduction, but also rebounded in some areas. Jiang Zhe said the observation was very different from that of the national EPA emissions inventory data, and it did not match the air quality goals of American local and federal agencies. Jiang Zhe further explained the difference between the observed data and the National Environmental Protection Agencys prediction data for NOx emissions. Our research found that 3 reasons led to this difference. First, the relative impact of emissions from industrial, regional and highways increases; secondly, the relative impact of gasoline emissions on roads is reduced; and third, these changes are slower than the expected reductions in fossil fuel emissions. The Guardian reported the findings of our team. The British Guardian newspaper reports that the current laws and regulations do not guarantee continuous improvement and encourage the use of more fossil fuels to make people go farther and farther from the wrong direction that threatens air quality and health. The Losangeles Times reported the research results of our team. The Losangeles times believes that the success of environmental measures in the past has made the impact of other pollution sources such as industrial boilers, residential water heaters, building equipment and diesel trucks. The report also said that in southern California, the number of bad air days has increased in the past two years in southern California, and the region had no federal health standards in the region last year, while 2016 and 2015 were 132 and 113 days, respectively. The mainstream view of the western countries was that the emissions of Asian pollutants increased rapidly with rapid industrialization, which would have a negative impact on the air quality of the United States. The Washington Post reported that because of the strengthening of air quality standards, the concentration of pollutants in China has declined significantly in recent years, so researchers have ruled out the hypothesis that the source of pollution comes from China.
