The export industries of China emit pollutants that manage to cross the Pacific Ocean, contributing to air pollution in the Western United States, according to research published in late January in reputable American journal. According to the authors, this research is the first to measure the amount of air pollutants in the United States due to Chinese production of exportable products and the global demand for these goods.
H This research, done in collaboration us imports with Chinese, American and British scientists and published in the journal Proceedings of the National Academy us imports of Sciences, explores the environmental impact of the interconnected economies. Scientists said that entrusting the production of goods in China consumers in the western world does not seem to be exempt from the environmental effects of air pollution."
The principal investigator of this study, Jidai Lin said that the purpose of the international research team was to examine cross-border effects of emissions from export us imports industries to indicate how consumption contributes to global atmospheric pollution. "We focused on the effects of trade," us imports says Mr. Lin, professor in atmospheric and oceanic sciences Physics School us imports of Peking University, adding that "the change of the place of production has a direct impact on the emissions of pollutants," he says.
Strong global winds, called westerlies (Western), fail within a few days to transport us imports air pollutants from China across the Pacific Ocean, with the result that there are "dangerous peaks of contaminants in the Western United States, the US researchers said on University of California, Irving. Using a modeling system called GEOS-Chem, scientists have estimated that in 2006, the Chinese transport of pollutants emitted during the production of goods for export to the United States, led to increased, up by 2% concentrations of sulfur compounds in Western States, us imports but also increased levels of ozone and carbon monoxide. However, because the Eastern States are more densely populated, the production of goods in China still has "overall beneficial effect on public health in the United States," even if the Western States incur slightly, say scientists.
The researchers us imports also investigated the influence of Chinese export industries on air quality of the country itself. They estimated that in 2006 in China, the production of export products to the United States accounted for 7.4% of sulfur dioxide emissions from production activities, 5.7% of the emissions us imports of nitrogen oxides, 4.6% of emissions of carbon monoxide and 3.6% of the soot.
Last year, exports accounted for 24.1% of all of China's economy, a drop from a peak of 35% recorded in 2007. Chinese exports to the United States, although it decreased in 2009 due to the global economic crisis, are recovering us imports strongly. With the new export policy of China, which includes only direct transfers between the mainland Chinese ports in the United States, for example, without the goods to pass through Hong Kong, revenue from exports last year reached $ 368.5 billion compared with 252.3 bn. in 2008. In contrast, China imported from the United us imports States products whose value did not exceed $ 152,600,000,000.
