Shenzhen concert hall in front of the conductor sculpture open arms like in the embrace of blue sky and white clouds, to protect the quality of air in Shenzhen, the city neighborhood committee and then a new move.
Becoming the first city to limit the sale and use of solvent-based coatings
Deepening the Air Pollution in Shenzhen. July 1, the full ban on serious harm to the public health of solvent-based paint (paint), adhesives and other substandard decoration materials, become the first in the country to limit the solvent-based paint (paint) sales and use of the city. The same period, the exhaust is not up to the standard non-road mobile machinery, will also be banned in Shenzhen City construction sites, factories, ports and other places to use. This is the reporter learned yesterday from the Municipal Habitat Environment Commission.
Deep handling of volatile organic compounds
Earlier this year, the Municipal Human Settlements Environment Committee on the prevention and control of air pollution has made clear objectives: 2015, the city's PM2.5 annual average concentration down to 33 micrograms / cubic meter. This year, more than half of this year, the results of the reporter from the Municipal Human Settlements Environment Committee announced in April 2015 Shenzhen City, ambient air quality status briefing to see this year in April, Shenzhen PM2.5 concentration of only 28 micrograms / cubic meter , Down 4 micrograms / cubic meter, and all pollutant concentrations than the same period last year have different degrees of decline, including nitrogen dioxide concentration, carbon monoxide concentration and ozone concentration. From January to April this year, Shenzhen ambient air quality composite index has been among the top 10, is always to maintain the "top ten" in the only one population of more than 10 million first-tier cities. Remediation effect is obvious.
Municipal People's Environment Committee Director Liu Chuhan told reporters that in order to achieve this year's PM2.5 down to 33 micrograms / cubic meter of the target, the Commission will be on July 1 and then out of heavy pressure, launched a number of air pollution control measures.
First, the deep management of volatile organic compounds. The implementation of the second phase of the limit of hazardous substances content of the standard, a comprehensive ban on the public health hazards of the solvent-based paint (paint), adhesives, paint, paint, paint, paint, paint, paint, paint, paint, And other unqualified decoration materials. To this end, Shenzhen has become the first country to limit the sale and use of solvent-based coatings (paints).
Second, the non-road mobile machinery with diesel engine for advanced management. July 1, 2015 the implementation of the Shenzhen Special Economic Zone, "in the use of non-road mobile machinery diesel engine exhaust emission limits and measurement methods" technical specifications, the future non-compliance of the non-road mobile machinery prohibited construction in Shenzhen Site, factory, port and so on.
Paint produces a lot of pollutants abroad has been banned
It is understood that the haze weather is an important cause of PM2.5, the main source of its production, vehicle emissions accounted for 30%, VOC (volatile organic compounds) emissions accounted for 21%, and the recent relevant information, VOC emissions , About 18% is produced by solvent-borne paint (paint) emissions.
Professional environmentalists told reporters that the paint to organic solvents for the thinner, the consumption of energy, pollution of the environment, toxic and harmful and flammable and explosive. In 2004 the EU has legislation to prohibit the production and use of paint. "Paint the harm is more than that, because it is from the oil and coal extracted from the organic solvent dilution treatment, not only need to consume fossil energy, organic solvents also contain a lot of benzene, toluene, xylene, formaldehyde and other toxic and hazardous substances , The volatile period of up to ten years, while the traditional paint often use a large number of toxic and harmful volatile organic solvents as thinner, some products also use free TDI curing agent, resulting in a lot of air pollution and long-term inhalation of these solvents And the curing agent of the volatile gas, easily lead to aplastic anemia, leukemia, tuberculosis, pleurisy and other serious diseases.
