空气质量指数(Air Quality Index,简称AQI)是定量描述空气质量状况的指数,其数值越大说明空气污染状况越严重,对人体健康的危害也就越大.根据国家标准,指数在0-50之间时,空气质量为优;在51-100之间时,空气质量为良;在101-150之间时,空气质量为轻度污染;在151-200之间时,空气质量为中度污染;在大于200时,空气质量为...
approximately 267 million, according to a census conducted in 2018. In 2019 it ranked as the 6thmost polluted country out of 98 contenders worldwide. The average US AQI figure for this year was 141 with levels of PM2.5 being 5 times over the World Health Organisation’s (WHO) exposure ...
as it is better known when it gathers in large accumulations. Whilst this a vital part of the upper atmosphere, on ground level it can prove to have very negative health effects, hence why it is counted amongst the several pollutants that go into calculating the AQI, or air quality index...
空气质量指数(Air Quality Index,AQI)是空气质量的评价指标,取值范围定为0～500,其中0～50、51～100、101～200、201～300和大于300,分别对应Ⅰ级、Ⅱ级、Ⅲ级、Ⅳ级和Ⅴ级标准的污染物浓度限定数值。Ⅰ级,空气质量评估为优,对人体健康无影响;Ⅱ级,空气质量评估为良,对人体健康无显著影响;Ⅱ级,为轻度污染,健...
