Shenzhen bans the sale of paint from July

The conductor's sculpture in front of the Shenzhen Concert Hall opened his arms like he was embracing the blue sky and white clouds. In order to protect Shenzhen's air quality, the City People's Committee has created new ones.

Become the first city in the country to limit the sales and use of solvent-based paints

Shenzhen's governance of atmospheric pollution is new. From July 1st onwards, the use of solvent-based paints (paints), adhesives, and other unqualified decorative materials that seriously endanger the health of citizens has been completely banned, and has become the first city in the country to restrict the sale and use of solvent-based paints (paints). During the same period, non-road-moving non-compliance mobile machines will also be prohibited from being used in construction sites, factories, and port terminals in Shenzhen. This reporter learned from the Municipal Habitat Environmental Committee yesterday.

Deep treatment of volatile organics

At the beginning of this year, the Municipal Human Settlements Environmental Committee put forward a clear goal for air pollution prevention and control: In 2015, the annual PM2.5 concentration in the city was reduced to 33 micrograms/cubic meter. Half of this year, how effective is it? The reporter saw from the “Environmental Air Quality Report of Shenzhen City in April 2015” published by the Municipal Human Settlements Environment Committee that in April of this year, the concentration of PM2.5 in Shenzhen was only 28 μg/m3, which was a drop of 4 μg/m3 compared to the same period last year. m, and the concentration of all pollutants has decreased in different ranges compared with the same period of last year, including nitrogen dioxide concentration, carbon monoxide concentration, and ozone concentration. From January to April this year, the Shenzhen Composite Index of Ambient Air Quality has been ranked in the top 10 in the country, and it is also the only first-line city with a population of over 10 million in the "Top 10". The effectiveness of remediation is obvious.

Liu Chuhan, director of the Municipal Human Settlements Environmental Committee, revealed to reporters that in order to achieve the target of reducing PM2.5 to 33 micrograms per cubic meter this year, the committee will make another heavy blow from July 1, launching a number of air pollution in depth management measures.

First, in-depth treatment of volatile organics. Promulgated the “Specification of hazardous materials for architectural decoration coatings and adhesives” SAR technical specifications, and implement the second phase of hazardous substance content limit standards from July 1, 2015, and completely disable solvent-based paints (paints) and adhesives that seriously endanger citizens’ health Unqualified decoration materials. For this reason, Shenzhen has become the first city in the country to limit the sales and use of solvent-based paints (paints).

Second, in-depth management of diesel engines for non-road mobile machinery. On July 1, 2015, the Shenzhen Special Economic Zone officially implemented the "Exhaust Smoke Limit Values ​​and Measurement Methods for Diesel Engines Used in Non-Road Mobile Machinery" specification. Non-road mobile machines that do not meet the standards for exhaust emissions are prohibited from building in Shenzhen. Sites, factories, ports, etc. are used.

Paint produces a lot of pollutants abroad

It is understood that haze weather is an important cause of PM2.5 emissions. Among its major sources, automobile exhaust emissions account for 30% and VOC (volatile organic compound) emissions account for 21%. Recent relevant data show that VOC emissions Of these, about 18% are generated by the discharge of solvent-based paints (paints).

Professional environmentalists told reporters that paints use organic solvents as diluents, which consume energy, pollute the environment, are poisonous and harmful, and are flammable and explosive. In 2004, the European Union had legislation that prohibited the production and use of paint. "The danger of paint is not limited to these, because it requires dilution treatment with organic solvents extracted from petroleum and coal. Not only does it need to consume fossil energy, organic solvents also contain a large amount of toxic and hazardous substances such as benzene, toluene, xylene, and formaldehyde. The volatilization period is more than ten years, while traditional paints often use a large number of toxic and harmful volatile organic solvents as diluents, and some products also use curing agents containing free TDI, resulting in large amounts of air pollution, and long-term inhalation of these solvents. Volatile gases from the curing agent can easily cause serious diseases such as aplastic anemia, leukemia, tuberculosis, and pleurisy."
