October Beijing, Tianjin and particulate matter concentration increased due to the emergence of thre ravbin

In October, the Beijing Tianjin Hebei particle concentration increased due to appear three times of heavy pollution – Beijing, Beijing, November 14, the Ministry of Environmental Protection released to the media today, the 2016 1-10 and October and the 74 key areas of air quality in the city. In October, the 13 city of Beijing Tianjin Hebei region average good days proportion was 64.1%, down 6.8 percentage points, the proportion of good days in Beijing city was 54.8%, down 19.4 percentage points; in October, the Beijing Tianjin Hebei region an increase of particle concentration, expert analysis of the main reasons is the Beijing Tianjin Hebei region meteorological conditions are not conducive to the spread of pollutants in the region, the three heavy pollution. Environmental Protection Department of environmental monitoring Secretary Luo Yi introduction, Beijing, Tianjin and 13 cities in the proportion of the average number of days 1-10 was excellent, an increase of 6.9 percentage points. PM2.5 concentration of 59 micrograms cubic meters, down by; PM10 concentration of 104 micrograms cubic meters, down by; O3 concentration of 179 micrograms cubic meters, an increase of 5.9%. October, Beijing, Tianjin and 13 cities in the proportion of the average number of days of excellent was 64.1%, down by 6.8 percentage points.

According to expert analysis, the main reason is, compared with the same period last year, the Beijing Tianjin Hebei region meteorological conditions are not conducive to the spread of pollutants in the region, there were three heavy pollution, affected by the particle concentration in the region increased. During the heavy pollution process of 13-15 October in Beijing, the concentration of particulate matter was the highest in the region, which had a great influence on the average monthly concentration of PM2.5.相关的主题文章:
