摘要
经过对湖北省宜昌市近三年的空气质量监测结果的分析,发现污染物全年的日浓度变化区间较大,细颗粒物PM_(2.5)、可吸入颗粒物PM_(10)和O_(3)仍然是影响宜昌市空气质量的主要污染物。相比于2019年和2020年,2021年PM_(2.5)最大日均值浓度降低,全年日均值达标天数显著提高,且PM_(2.5)年均值浓度超标倍数在减小。O_(3)在夏季温度较高时达到全年最高的浓度,NO_(2)、SO_(2)的日均值浓度在每年的11月—次年2月相对较高。空气质量的变化与人类的生产生活是密不可分的。
After analyzing the air quality monitoring results of Yichang City,Hubei Province for the past three years,it is found that the daily concentrations of pollutants vary in a wide range throughout the year,with fine particulate matter PM_(2.5),respirable particulate matter PM_(10) and O_(3) still being the main pollutants affecting air quality in Yichang City.2021 shows a decrease in the maximum daily average concentration of PM_(2.5) compared to 2019 and 2020,with the annual daily average O_(3) reaches its highest concentration throughout the year in summer when temperatures are high,and NO_(2) and SO_(2) are relatively high in November-February of the next year.The changes in air quality are inseparable from human production and life.
