Chinese experts ask to regulate the use of aerosols due to its polluting effect

Chinese experts ask to regulate the use of aerosols due to its polluting effect



The volatile organic compounds that use perfumes, lacquer and air fresheners are part of the problem of the contamination that beats Beijing, assure several Chinese scientists who have requested the regulation of this type of products.

In statements made today by the Global Times, experts say that these compounds contribute up to 12% of PM 2.5 particles scattered in the air (the smallest and noxious), and among the articles that recommend regular are also insecticides and Cleaning products.

"Policies must be established to regulate these sources of indirect contamination, since strict measures have already been taken for the pollution generated by vehicles and the burning of coal, which contribute to almost half of the 2.5 particles," he told the newspaper. researcher of the Institute of Atmospheric Physics of the Chinese Academy of Sciences Wang Genchen.

As he explained, these compounds do not directly produce PM 2.5 particles, but they add to them after generating other particles due to a series of physical and chemical reactions.

A study by the Beijing Municipal Environmental Protection Bureau already warned in May that the proportion of pollution caused by activities of daily life is increasing in the Chinese capital, although this proportion decreases in winter when coal starts to burn for heating.

Another expert, Tang Xiaoyan, also stressed the importance of not ignoring these "less significant" sources and recalled that before the Olympic Games in Beijing (2008) even laundries had to close their stores for their use of chemicals to improve the quality of the air of the city.

For its part, the Beijing Municipal Environmental Protection Bureau reported on Thursday that the average concentration of PM2.5 particles in the Chinese capital decreased by 16.7% year-on-year in the first three quarters of the year.

However, the smog returns to surround the city since last weekend, when the concentration of this type of particles has exceeded 200 micrograms per cubic meter.

The Environmental Monitoring Center forecasts that pollution in Beijing will peak on Monday due to "weather conditions that are not favorable to disperse pollutants."

In recent years, the Chinese government has launched several plans to promote cleanliness and air quality through measures such as closing factories, limiting the most polluting vehicles and replacing coal with cleaner energies for heating and cooking in homes. .
