Perhaps due to occupational habits, Wen Xiangcai, the chairman of the Central Committee of the Revolutionary Committee and the researcher of the China Environmental Monitoring Center, was almost eager to explain to reporters clearly about the ins and outs of PM2.5.

"Why PM2.5 will burst into the red overnight, the reason is that compared with the past, people's requirements for quality of life have been greatly improved. The environmental protection department has never published monitoring data before, so that everyone has accumulated dissatisfaction." Wen Xiangcai believes that after the “swine science” of hazy days last year at the end of last year, people’s attention to the urban environment and the public’s own environmental awareness have been greatly improved, and the government has also passed the “Ambient Air Quality Standard” and “Environmental Air Quality. Quality Control Index (AQI) Technical Regulations (Trial) and other laws. The question that deserves the most attention now is how to make China's PM2.5 monitoring use "Chinese-made" high-efficiency instruments.

In this year's “Government Work Report”, the report clearly points out that the PM2.5 governance work will be promoted in three steps: The first step is to implement PM2 in “Three Districts and Nine Groups” and 31 provincial capital cities in 2012. 5. The second step is to carry out the inspection of PM2.5 in 113 key cities, and to cover full coverage above the prefecture level by 2015.

“According to the estimation, the total value of the equipment purchased by the entire nationwide monitoring network is estimated to be nearly 2.8 billion yuan. However, from the perspective of the current level of development of the Chinese environmental protection industry, there are not many domestically produced products that meet the standards and requirements for use.” Wen Xiangcai said that this means that once the construction of the monitoring network is started, 70% of the 2.8 billion yuan investment will flow into the pockets of foreign instrument manufacturers.

"China's environmental protection industry started relatively late. Previously, investment in equipment and equipment has not been large." Wen Xiangcai said that now facing the development opportunities brought about by PM2.5, the entire industry is obviously inadequately prepared.

“From our monitoring department, it is natural that we want to be able to use more domestically produced monitoring equipment.” Wen Xiangcai pointed out that at present, there are some high-end environmental testing equipment manufacturers that have developed relatively rapidly. However, if the entire industry is to be upgraded, the country Give enough policy and financial support. In addition, the development of domestic equipment and instruments should also have a set of advanced environmental air monitoring technology system with independent intellectual property rights and environmental air quality assessment technology method system. According to Wen Xiangcai, the China Environmental Monitoring Center and other departments have already stepped up efforts in this area.

"Of course, we should understand that monitoring data becomes more accurate and not a goal. Only improvement is fundamental." Wen Xiangcai said.
