Japan conducts the Asia's most strict PM2, 5 emission limits

Wide network Beijing on December 6 message according to China of sound reported, near days, China multiple area suffered fog haze weather, air quality obvious fell, capital Beijing 4th, night more is reached has in the heavy of pollution, to public of life travel brings does not small of effect. people recently also total talked about a data, is PM2.5. This is may into lung particles property of numerical, and on PM2.5 numerical has directly effect of is car exhaust. 10 lawsuit was lose 1.2 billion yen in neighbours Japan, had has had car exhaust on human caused hurt of case, even for this playing has one up to 10 years of lawsuit. more situation, we now Japan observer Ye Qianrong: Ye Qianrong: Japan from 80 generation began also has been in on PM2.5 subtle particles on human of effect for had many of analysis and discussion, last expert consistent think, in large city among of PM2.5 tiny particles of main sources is car exhaust, especially
Diesel exhaust, because we know that, although the volcanic ash and dust of the ground construction it is also possible to form 2.5 micron particles, but the analysis results show that most of them were from automobile exhaust.　　Second, the automobile exhaust emission of 2.5 micron particles also have a strong carcinogen. based on the findings on these two points, in Japan there was a public report of local government and 7 diesel car production company litigation, the litigation for more than 10 years, and finally to compensation for the accused to the public end of 1.2 billion yen. Japan conducts the Asia's most strict PM2.5 emissions standards Ye Qianrong: this action indirectly touched the automobile manufacturers and local government legislation to PM2.5 particles, 2003 Tokyo launched Japan's first on PM2.5 particles, particularly diesel engine, automobile exhaust particulates emissions for legislation, I still remember the first day of implementation, all entering the Tokyo expressway into
And the entrance to the main trunk, police inspect all automobile exhaust pipe, at that time did not use many high-tech tools are using a white towel and let the car engine, and then use a white towel stuck exhaust-opened if white towels to black after it was determined that it must use a filter is not installed, prohibited in Tokyo.　　Has been almost 10 years later, now that these car manufacturers are produced only with the filter of car, at the same time, emissions standards reached European standard, which makes 2.5 grains dropped sharply in Tokyo, 2.5 is currently in Tokyo particle emissions standards are the strictest in Asia, which required does not exceed 35 µg per day, average no more than 15 micrograms. After the enactment of law enforcement in order to drive change Ye Qianrong: I think a lot of Asian cities in the future will continue to start the legislative process, I personally think that the three key, the first is the legislative, many car companies in the production design
