for example

???? xinhuanet.com Beijing 5 June report Cheap Marlins jerseys (reporter Ni Yuanjin) since 2014, the city of Beijing in the prevention and control of atmospheric pollution and other environmental governance in the field Cheap Red Sox Jerseys of unprecedented. Since January 1st, first in the country to improve the four major pollutants Cheap kids MLB Jerseys sulfur dioxide, nitrogen oxide, chemical oxygen demand, ammonia nitrogen charging standards, 14 - 15 times after the adjustment of the standards for the original standard, the highest level. The use of economic means to promote pollution reduction, Beijing is a prelude.

???? however, experts said, although the treatment of haze general idea is correct, but the poor implementation, governance is difficult to short-term effect.

???? composite haze control difficult over Europe and the United States

???? the Chinese Academy of Sciences "atmospheric haze after that and He Hong, chief scientist for control" special China Research Institute of Atmospheric Physics researcher Wang Yuesi, atmospheric pollution in developed countries show "features", develop the industrial emissions, urbanization and motor vehicle civilization, China is in the industrialization development of haze and vehicle. The synchronous case, the superposition and pollution caused by interaction of compound pollution, different from the last century, London (soot type), Losangeles (motor vehicle as the primary reason) relative to the single pollution, governance difficult than western countries.

???? this compound pollution is obviously reflected in the data: according to the PM2.5 group with the Beijing environmental protection monitoring center of the real-time online monitoring display, organic compounds, sulfate, nitrate as main material.

???? Beijing city environmental protection monitoring center director Zhang Dawei introduced, nitrate are mainly from the burning of coal and oil and gas, motor vehicle emissions very high proportion of sulfate; sulfur dioxide from coal emissions, high humidity in the air, conversion to produce sulfate; organic compounds derived from coal, petroleum burning incomplete combustion products, such as waste incineration, open-air barbecue, biomass burning, cooking oil fume, chemical production etc..

???? pollution complexity lies not only in the superposition effect, also is a chemical reaction occurs between different sources of pollution emissions of pollutants, so as to further increase the possibility of fog haze, conditions of Cheap White Sox Jerseys compound pollution, capacity of the atmospheric environment on the reductions.

???? "for the second industries accounted for only 2 of Beijing ', motor vehicle pollution is an important source of nitrogen oxides'." Hong he stressed, high concentrations of nitrogen oxides are present, the capacity of the atmospheric sulfur dioxide will decline sharply, for example, the Beijing Tianjin Hebei haze is very serious, the concentration of sulfur dioxide is also equivalent to the London smog event of 1 / 10, but due to coexist with other pollutants, atmospheric capacity decline phenomenon is very obvious, Cheap royals Jerseys the hitherto unknown challenge to management haze.

????? Development pressure "enterprise first random point pollution control facilities"

???? how to deal with the relationship between economic development, is the constraints of environmental governance. In many areas, finance is "eat" fiscal, a few years ago to undertake "pollution" industry, now the cost of environmental governance is not available. "If you don't develop the economy, not only cannot improve >
