今天,空氣過濾網的專業人(ren)士為我們分析五月(yue)空氣(qi)質量情(qing)(qing)況(kuang)(kuang),全(quan)國各地的空氣(qi)情(qing)(qing)況(kuang)(kuang)有著(zhu)怎樣的變(bian)化(hua)呢?哪些城市(shi)的污染情(qing)(qing)況(kuang)(kuang)有所改善(shan)?哪些地區又(you)會加(jia)重呢?
環(huan)境(jing)保護部(bu)有關負責人近日向媒(mei)體發(fa)布(bu)了2013年5月份京津冀(ji)、長三角(jiao)、珠三角(jiao)區域及直轄市、省會城(cheng)市和(he)計(ji)劃(hua)單列市等(deng)74個(ge)(ge)城(cheng)市空氣質量狀況。結果顯示(shi),5月份,74個(ge)(ge)城(cheng)市平均達標天數(shu)(shu)比(bi)例為60.1%,超標天數(shu)(shu)比(bi)例為39.9%,其中輕度污染(ran)占(zhan)29.4%,中度污染(ran)占(zhan)8.3%,重度污染(ran)占(zhan)2.1%,嚴(yan)重污染(ran)占(zhan)0.1%。
其中,海口、珠海、深(shen)圳和(he)福州的達標(biao)(biao)天(tian)數(shu)比(bi)例為100%,14個(ge)城市達標(biao)(biao)天(tian)數(shu)在(zai)80%-100%之(zhi)(zhi)間,34個(ge)城市達標(biao)(biao)天(tian)數(shu)在(zai)50%-80%之(zhi)(zhi)間,22個(ge)城市達標(biao)(biao)天(tian)數(shu)不(bu)足50%,首要污染物為O3和(he)PM2.5。與(yu)(yu)上(shang)(shang)月(yue)相(xiang)比(bi),74個(ge)城市達標(biao)(biao)天(tian)數(shu)比(bi)例降低3.4個(ge)百分(fen)點,重度污染和(he)嚴(yan)重污染比(bi)例增加0.2個(ge)百分(fen)點。按照《環(huan)境空(kong)氣質(zhi)量標(biao)(biao)準》(GB3095-2012)評價(jia),與(yu)(yu)上(shang)(shang)月(yue)相(xiang)比(bi),74個(ge)城市5月(yue)份 PM2.5、PM10、SO2和(he)NO2月(yue)均濃度均下(xia)降,CO超標(biao)(biao)率(lv)基(ji)本(ben)持平(ping),但隨著(zhu)光照增強和(he)氣溫上(shang)(shang)升(sheng),O3平(ping)均超標(biao)(biao)率(lv)明顯上(shang)(shang)升(sheng)。
PM2.5平(ping)(ping)(ping)均(jun)超(chao)(chao)標(biao)(biao)率(lv)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)20.3%,合肥(fei)市(shi)大(da)(da)(da)日(ri)(ri)均(jun)值(zhi)(zhi)(zhi)(zhi)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)296μg/m3,大(da)(da)(da)超(chao)(chao)標(biao)(biao)倍數為(wei)(wei)(wei)(wei)(wei)(wei)(wei)2.9。PM2.5月(yue)均(jun)濃度(du)(du)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)55μg/m3,石家莊(zhuang)(zhuang)市(shi)大(da)(da)(da)值(zhi)(zhi)(zhi)(zhi)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)113μg/m3。PM10平(ping)(ping)(ping)均(jun)超(chao)(chao)標(biao)(biao)率(lv)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)17.5%,呼和(he)(he)(he)浩特(te)市(shi)大(da)(da)(da)日(ri)(ri)均(jun)值(zhi)(zhi)(zhi)(zhi)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)591μg/m3,大(da)(da)(da)超(chao)(chao)標(biao)(biao)倍數為(wei)(wei)(wei)(wei)(wei)(wei)(wei)2.9。PM10月(yue)均(jun)濃度(du)(du)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)101μg/m3,石家莊(zhuang)(zhuang)市(shi)大(da)(da)(da)值(zhi)(zhi)(zhi)(zhi)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)289μg/m3。NO2平(ping)(ping)(ping)均(jun)超(chao)(chao)標(biao)(biao)率(lv)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)1.5%,唐(tang)山(shan)(shan)市(shi)大(da)(da)(da)日(ri)(ri)均(jun)值(zhi)(zhi)(zhi)(zhi)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)109μg/m3,大(da)(da)(da)超(chao)(chao)標(biao)(biao)倍數為(wei)(wei)(wei)(wei)(wei)(wei)(wei)0.4。NO2月(yue)均(jun)濃度(du)(du)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)37μg/m3,唐(tang)山(shan)(shan)市(shi)大(da)(da)(da)值(zhi)(zhi)(zhi)(zhi)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)80μg/m3。SO2平(ping)(ping)(ping)均(jun)超(chao)(chao)標(biao)(biao)率(lv)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)0.9%,唐(tang)山(shan)(shan)市(shi)大(da)(da)(da)日(ri)(ri)均(jun)值(zhi)(zhi)(zhi)(zhi)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)260μg/m3,大(da)(da)(da)超(chao)(chao)標(biao)(biao)倍數為(wei)(wei)(wei)(wei)(wei)(wei)(wei)0.7。SO2月(yue)均(jun)濃度(du)(du)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)29μg/m3,唐(tang)山(shan)(shan)市(shi)大(da)(da)(da)值(zhi)(zhi)(zhi)(zhi)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)141μg/ m3。CO平(ping)(ping)(ping)均(jun)超(chao)(chao)標(biao)(biao)率(lv)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)0.2%,唐(tang)山(shan)(shan)市(shi)大(da)(da)(da)日(ri)(ri)均(jun)值(zhi)(zhi)(zhi)(zhi)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)4.1 mg/ m3,大(da)(da)(da)超(chao)(chao)標(biao)(biao)倍數為(wei)(wei)(wei)(wei)(wei)(wei)(wei)0.03。O3日(ri)(ri)大(da)(da)(da)8小時均(jun)值(zhi)(zhi)(zhi)(zhi)的(de)平(ping)(ping)(ping)均(jun)超(chao)(chao)標(biao)(biao)率(lv)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)26.9%,邯鄲市(shi)大(da)(da)(da)值(zhi)(zhi)(zhi)(zhi)為(wei)(wei)(wei)(wei)(wei)(wei)(wei)430μg/ m3,大(da)(da)(da)超(chao)(chao)標(biao)(biao)倍數為(wei)(wei)(wei)(wei)(wei)(wei)(wei)1.7。按照城市(shi)空氣(qi)質量(liang)綜合指數進行評價,石家莊(zhuang)(zhuang)、唐(tang)山(shan)(shan)、邢臺、邯鄲、濟南、保(bao)定、鄭州、北京(jing)、衡水和(he)(he)(he)天津的(de)空氣(qi)質量(liang)較差;海(hai)口、惠州、福州、珠海(hai)、舟山(shan)(shan)、中山(shan)(shan)、深圳、江門、東莞和(he)(he)(he)廈門的(de)空氣(qi)質量(liang)相對較好(hao)。

關于五月空氣質量情況我們就選擇(ze)其(qi)中的(de)(de)部分城(cheng)市為(wei)例為(wei)您做出介紹,尤其(qi)是在(zai)我們生(sheng)活的(de)(de)城(cheng)市上海,以(yi)及一些污染(ran)較(jiao)為(wei)嚴重的(de)(de)城(cheng)市,這些數據都是大家需要去了解的(de)(de)。
