Shanghai reduce air pollution warning threshold weight

  ■ Wang Jintao has increased during the new plan after lowering the threshold, heavy air pollution warning the number of starts will implement than the old version of the plan: drawing. But this does not mean a deterioration in air quality, but the districts, departments and relevant units in the degree of pollution has not arrived yet severe, has carried out ahead of emergency mitigation, efforts to alleviate air pollution, is actually a more sophisticated management tools yesterday Shanghai Environmental Protection Bureau released "Shanghai air heavily polluted specific contingency plans (2018 Edition)", implemented from now on.

And two years ago, compared to the old version of the plan, the new plan to launch heavy air pollution warning conditions were optimal adjustment to reduce the threshold to start the next warning will be issued timely and more frequent.

The new version of the heavy air pollution warnings and special emergency plan to start standard has been the Yangtze River Delta is the lowest.

So self-pressurized, in addition to heavy air pollution warning closer to real life needs of the people, but also to let the new plan to become Shanghai’s Yangtze River Delta region to promote the implementation of early-warning criteria with a heavy air pollution, air pollution in unison in the face. How light pollution plus short-term heavy pollution started warning warning start threshold specific reduced? First of all, and compared to the old version, the new forecast as a result of plans to start conditions, increase the amount of air pollution heavy advance warning when there is heavy pollution forecasting, early warning will start at least one day in advance.

The original, in order to ensure scientific rigor, monitoring will consume a long time to make predictions, and start the appropriate level of warning.

Available to the public, such a warning is often too late, and even some surprise. Secondly, the old version of the four threshold has been lowered in the new version three years.

Blue warning from the original "One heavily polluted, moderately polluted or a day and may appear short heavy pollution" adjusted "One day short mild or moderate pollution and severe pollution that may arise."

Yellow warning from the original "two days of severe pollution" adjusted "One day heavily polluted." Orange alert from the original "One serious pollution, or severe pollution than three days" adjusted "One serious pollution, or two or more heavily polluted." Red alert starting condition remains unchanged, "the next day or Ambient Air Quality Index (AQI) is greater than 400." Why lower the threshold? Municipal Environmental Protection Bureau chief engineer Bai Guoqiang said that the first is based on the actual situation of the current air quality in Shanghai, the original threshold appear too "high."

Shanghai’s emergence last day of air pollution, heavy pollution mainly for a short time, a day or two or persistent mild or moderate pollution, basically there have been no cases of serious pollution or three day that are heavily contaminated and therefore orange and higher levels of heavy air pollution warning has not been activated, blue, yellow warning number of starts are also numbered. Followed by fully consider the feelings of the public. Although last year a lot of time and did not release heavy air pollution warning, and regulators insist on continued control air, but some lesser degree of contamination of the day, the public senses still relatively poor, warning does not start, did not take special emergency measures will Some people mistakenly think that regulators’ inaction. "

Municipal Environmental Protection Bureau said the increase in the period after lowering the threshold, heavy air pollution warning launch the new plan frequency plan will be implemented than the old version.

But this does not mean a deterioration in air quality, but the districts, departments and relevant units in the degree of pollution has not arrived yet severe, has carried out ahead of emergency mitigation, efforts to alleviate air pollution, is actually a more sophisticated management tools.

If you frequently start early warning, alert level corresponding to the relevant emergency measures will also be implemented frequently. For example, the yellow warning starts, schools and preschools to stop all outdoor physical education and outdoor activities, major mass outdoor sports also recommend the suspension, they may have life and public travel inconvenience. However, the fundamental purpose of this is to protect the health of everyone on the public understanding and support.

Yangtze River Delta will start in early warning unison Bai Guoqiang frankly, with the implementation of the new plan of Shanghai, the Yangtze River Delta provinces and cities with high and low threshold to start out on the heavy air pollution warning.

This step with direct impact Yangtze linkage effects of air pollution.

However, the Yangtze River Delta has recently been reached on the "lockstep" consensus, will jointly develop early warning emergency response plan heavy air pollution in Yangtze River Delta, with a threshold to start early warning, emergency response and to take similar measures. Ecological Environment Ministry also see the problem "out of step" in some areas, will soon introduce relevant guidance.

Municipal Environmental Protection Bureau said the opinion, once introduced, the Yangtze River Delta will immediately start the preparation of the relevant plans. According to reports, the Ministry of Ecology air environment relevant guidance given heavy pollution warning threshold may be lower than in Shanghai to start the new plan, Forced area more solidarity in the face of heavy air pollution.

Bai Guoqiang said, according to the scheduled time node, starting next year the second stage of the Yangtze River Delta region from ship emission control, emission control plan must be implemented within a certain port and the surrounding waters emission control areas of the ship, but taking into account the protection of Chinese international import Expo and other factors, the Yangtze River Delta is planning to enter the second phase of time in advance to October this year. Cross-regional joint disciplinary mechanisms dishonesty serious environmental businesses this year there has been progress. Yangtze River Delta in what promises to be a serious, serious dishonesty judge how unity, discipline and other aspects of how the joint agreement. At present, the Yangtze River Delta has a preliminary list of 14 categories of environmental situation of serious dishonesty, until the final standard came out, around the Yangtze River Delta will each match generates a "blacklist", uploaded to the Yangtze River Delta unified credit platform, a unified standard promises discipline who promises to achieve a straitjacket imposed. To achieve precise haze rule, the Yangtze River Delta will also enhance air quality monitoring station data, sharing information sources on-line monitoring data, atmospheric super station data and source emission inventory, etc., to provide a more accurate basis for decision making for regional haze rule.
