秦皇岛臭氧污染现状分析

The Analysis of Ozone Pollution in Qinhuangdao Area

根据秦皇岛生态环境局官方臭氧监测数据,分析2014—2020年秦皇岛地区臭氧1 h平均浓度的分布规律。分析结果表明,臭氧浓度总体呈逐年增长趋势,臭氧浓度超标日趋严重,其7 a平均值为61μg/m^(3)。超标时数沿海地带为839 h,北部县区为1402 h,沿海地带臭氧1 h均值为57.6μg/m^(3),北部县区为65.8μg/m^(3),2017年超标最多,为1728 h。

Based on official data of the ozone monitoring that came from Qinhuangdao Ecological and Environment Bureau,the distribution characteristic about the 1-hour average concentration of ozone was analyzed in Qinhuangdao area from 2014 to 2020.The result shows that the ozone concentration has been increasing year by year,and over-standard of ozone concentration is becoming more and more serious,its 7-year average of ozone concentration is 61μg/m^(3).Ozone concentration exceeds the national standard for 839 hours in coastal area,and 1402 hours in northern area.1-hour average of ozone concentration is 57.6μg/m^(3)in coastal areas and 65.8μg/m^(3)in northern area.In 2017,there is 1278 hours in which ozone concentration exceeded the national standard,and it was the most in 7-year.
