發布時間:2021-10-22   瀏覽:1036次

空(kong)氣(qi)污(wu)(wu)(wu)染(ran)(ran)(ran)指(zhi)(zhi)數(shu)(Air  pollution  Index,  簡稱API)就是(shi)將常規監測(ce)的(de)(de)(de)(de)幾種(zhong)空(kong)氣(qi)污(wu)(wu)(wu)染(ran)(ran)(ran)物濃(nong)度(du)(du)簡化成(cheng)為(wei)(wei)單一的(de)(de)(de)(de)概念性指(zhi)(zhi)數(shu)值(zhi)(zhi)(zhi)(zhi)形式,并分(fen)級表(biao)征空(kong)氣(qi)污(wu)(wu)(wu)染(ran)(ran)(ran)程(cheng)度(du)(du)和(he)空(kong)氣(qi)質(zhi)量(liang)(liang)狀況(kuang),適(shi)合于(yu)表(biao)示城(cheng)市的(de)(de)(de)(de)短期空(kong)氣(qi)質(zhi)量(liang)(liang)狀況(kuang)和(he)變化趨勢。空(kong)氣(qi)污(wu)(wu)(wu)染(ran)(ran)(ran)指(zhi)(zhi)數(shu)是(shi)根據空(kong)氣(qi)環(huan)(huan)境質(zhi)量(liang)(liang)標準和(he)各(ge)項污(wu)(wu)(wu)染(ran)(ran)(ran)物的(de)(de)(de)(de)生態環(huan)(huan)境效應(ying)及其對人體(ti)健康的(de)(de)(de)(de)影響來確定污(wu)(wu)(wu)染(ran)(ran)(ran)指(zhi)(zhi)數(shu)的(de)(de)(de)(de)分(fen)級數(shu)值(zhi)(zhi)(zhi)(zhi)及相應(ying)的(de)(de)(de)(de)污(wu)(wu)(wu)染(ran)(ran)(ran)物濃(nong)度(du)(du)限值(zhi)(zhi)(zhi)(zhi)。空(kong)氣(qi)質(zhi)量(liang)(liang)周報所用的(de)(de)(de)(de)空(kong)氣(qi)污(wu)(wu)(wu)染(ran)(ran)(ran)指(zhi)(zhi)數(shu)的(de)(de)(de)(de)分(fen)級標準是(shi):(1)空(kong)氣(qi)污(wu)(wu)(wu)染(ran)(ran)(ran)指(zhi)(zhi)數(shu)(API)50點(dian)(dian)  對應(ying)的(de)(de)(de)(de)污(wu)(wu)(wu)染(ran)(ran)(ran)物濃(nong)度(du)(du)為(wei)(wei)國家空(kong)氣(qi)質(zhi)量(liang)(liang)日(ri)均(jun)值(zhi)(zhi)(zhi)(zhi)一級標準;  (2)API  100點(dian)(dian)對應(ying)的(de)(de)(de)(de)污(wu)(wu)(wu)染(ran)(ran)(ran)物濃(nong)度(du)(du)為(wei)(wei)國家空(kong)氣(qi)質(zhi)量(liang)(liang)日(ri)均(jun)值(zhi)(zhi)(zhi)(zhi)二(er)級標準;(3)API  200點(dian)(dian)對應(ying)的(de)(de)(de)(de)污(wu)(wu)(wu)染(ran)(ran)(ran)物濃(nong)度(du)(du)為(wei)(wei)國家空(kong)氣(qi)質(zhi)量(liang)(liang)日(ri)均(jun)值(zhi)(zhi)(zhi)(zhi)三級標準;(4)API更高值(zhi)(zhi)(zhi)(zhi)段的(de)(de)(de)(de)分(fen)級對應(ying)于(yu)各(ge)種(zhong)污(wu)(wu)(wu)染(ran)(ran)(ran)物對人體(ti)健康產生不同影響時(shi)的(de)(de)(de)(de)濃(nong)度(du)(du)限值(zhi)(zhi)(zhi)(zhi)。

根據(ju)我(wo)國空氣(qi)污染特點和(he)污染防(fang)治重點,  目前計入(ru)空氣(qi)污染指數(shu)的(de)項(xiang)目暫定為:  二氧(yang)化(hua)硫、氮氧(yang)化(hua)物和(he)可吸入(ru)顆(ke)粒物。隨著環境保護工作的(de)深(shen)入(ru)和(he)監(jian)測技術水平的(de)提高,將調整增加其(qi)它(ta)污染項(xiang)目,以便更為客觀(guan)地反映污染狀況(kuang)。
