Beijing Tianjin Hebei will unify the heavy pollution warning standard to limit the largest contribution to emission reduction original title: Beijing and Tianjin will be unified heavy pollution warning standard of Beijing daily news (reporter Jiang Mengwei) in November 2nd, announced that the day before, the revised "Tianjin third Tianjin heavy pollution weather emergency plan" and on October 31st formally implemented. So far, the city of Beijing, Tianjin, Hebei province and the cities of Henan Province, Shandong province have been determined to implement a unified emergency warning standards. The industry said that this means that in the future, Beijing, Tianjin and the surrounding area can effectively avoid the occurrence of heavy pollution weather due to the difference in response to different temporary emission reduction measures caused by the start of the problem is not timely. According to reports, the Beijing Tianjin Hebei three "line" heavy pollution emergency warning standards for air quality index is more than 200, the air quality index issued blue warning for 2 days, 200 issued a yellow warning and air quality index for 3 days, 1 days and 200 > 300, released orange signal warning of air quality index for 4 days > 200 > 300 and lasted 2 days or 1 days of air quality index reached 500 issued a red alert. According to reports, the emergency plan of the Tianjin revised air quality index also increased the average forecast of more than 500 and will last for more than 1 days, primary and secondary schools and kindergartens will be closed; stopping all outdoor activities; flexible working units. So far, many people still remember Beijing in November last year began to appear heavy pollution weather, every heating season, the daily air quality has become a data that citizens are most worried. With the emergence of heavy pollution weather, various colors are increasingly warning by the public familiar with it, especially one of the most extensive measures — red warning in Beijing under the implementation of the single motor vehicle limit line policy. There is no denying that the industry was almost the country’s most stringent heavy pollution weather warning program is indeed to improve the air quality in Beijing has made a significant contribution to Beijing. In December of last year the Beijing heavy pollution weather occurs as an example, the director of the Municipal Environmental Monitoring Center Zhang Dawei said, when the red warning implementation lasted about 90 hours, Beijing PM2.5 decreased the concentration of 20%-25%, the emission reduction measures, single and double limit line measures the maximum contribution to emission reduction. Moreover, Zhang Dawei further revealed that the Beijing heavy pollution days last year, about 80% at the same time a wide range of Tianjin and Hebei regional heavy pollution, "according to estimates, with regional transmission of Beijing annual average concentration of PM2.5 is about 28%-36%, while the specific numerical can not accurately, but around the sewage will affect the air quality the surrounding city is certain". Moreover, after the Ministry of environmental protection has also clearly pointed out after the inspection, the presence of some local governments in Beijing, Tianjin and emergency measures are not timely enough to solve the problem. Experts said that in this case, Tianjin, Hebei and Beijing in the region can occur when the heavy pollution weather emergency measures together with the start is particularly important. However, after the unification of Beijing, Tianjin and early warning standards, people are more concerned about the corresponding emission reduction measures at all levels can be raised to the same high.相关的主题文章:
