中證網訊（記(ji)者(zhe) 劉楊）生態環(huan)(huan)境部官微(wei)2月(yue)12日消息(xi)，最近，正值(zhi)湖北(bei)省武(wu)漢市(shi)應對新型冠(guan)狀(zhuang)病毒感染肺炎(yan)疫情的關鍵時(shi)刻(ke)，有(you)國外網站(zhan)報(bao)道，武(wu)漢市(shi)空(kong)氣(qi)中的SO2指標(biao)濃度(du)上升明顯，引發了人們的關注。中國環(huan)(huan)境監測(ce)總站(zhan)有(you)關負責同志就武(wu)漢市(shi)近期環(huan)(huan)境空(kong)氣(qi)質量相關問題(ti)回答(da)了記(ji)者(zhe)提問。

　　上(shang)(shang)述負責同志表(biao)示，自(zi)(zi)新冠肺炎(yan)疫(yi)情發(fa)生(sheng)以來(lai)，生(sheng)態(tai)環境部高度重視疫(yi)情地區(qu)環境監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)工(gong)作，印發(fa)《關(guan)于做好應(ying)(ying)對(dui)新型(xing)(xing)冠狀(zhuang)病毒感(gan)染(ran)(ran)肺炎(yan)疫(yi)情生(sheng)態(tai)環境應(ying)(ying)急監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)工(gong)作的通知(zhi)》和《應(ying)(ying)對(dui)新型(xing)(xing)冠狀(zhuang)病毒感(gan)染(ran)(ran)肺炎(yan)疫(yi)情應(ying)(ying)急監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)方(fang)案》。環境監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)系統克(ke)服困難(nan)，積極(ji)開(kai)展環境空(kong)氣(qi)(qi)、地表(biao)水和飲用水源(yuan)地的監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)工(gong)作，最大(da)限(xian)度保(bao)障空(kong)氣(qi)(qi)質(zhi)(zhi)量(liang)(liang)(liang)自(zi)(zi)動監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)站、地表(biao)水環境質(zhi)(zhi)量(liang)(liang)(liang)自(zi)(zi)動監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)站的正常(chang)運行(xing)，全(quan)力保(bao)障環境質(zhi)(zhi)量(liang)(liang)(liang)安(an)全(quan)。武(wu)漢(han)市(shi)共布設有(you)10個國控(kong)空(kong)氣(qi)(qi)質(zhi)(zhi)量(liang)(liang)(liang)監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)點位，按照《環境空(kong)氣(qi)(qi)質(zhi)(zhi)量(liang)(liang)(liang)標準》（GB 3095-2012），開(kai)展SO2、NO2、PM2.5、PM10、CO、O3?六項指標自(zi)(zi)動監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)。除夕至正月(yue)十(shi)七，武(wu)漢(han)市(shi)10個國控(kong)空(kong)氣(qi)(qi)質(zhi)(zhi)量(liang)(liang)(liang)監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)點位6項污(wu)染(ran)(ran)物(wu)的有(you)效小時數據(ju)獲(huo)取率達(da)99%以上(shang)(shang)。監(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)數據(ju)通過“全(quan)國城市(shi)空(kong)氣(qi)(qi)質(zhi)(zhi)量(liang)(liang)(liang)實時發(fa)布平臺”公開(kai)發(fa)布。

　　監(jian)測(ce)(ce)(ce)結果顯示，2020年春節以來，武(wu)漢(han)市環境(jing)空(kong)氣(qi)質量狀況(kuang)總(zong)體(ti)(ti)穩定，除2月(yue)5日(ri)輕度(du)(du)污染（首要污染物(wu)PM2.5）外，空(kong)氣(qi)質量均為優良(liang)。除夕至正(zheng)月(yue)十(shi)七(qi)，PM2.5平均濃(nong)度(du)(du)為?50μg/m3?，同(tong)比下(xia)降(jiang)38%，PM10?平均濃(nong)度(du)(du)為?56μg/m3?，同(tong)比下(xia)降(jiang)42%，SO2平均濃(nong)度(du)(du)為?7μg/m3?，同(tong)比下(xia)降(jiang)22%，NO2平均濃(nong)度(du)(du)為?22μg/m3?，同(tong)比下(xia)降(jiang)45%，CO?濃(nong)度(du)(du)為?1.0mg/m3?，同(tong)比下(xia)降(jiang)29%，均顯著(zhu)好(hao)于去(qu)年同(tong)期，空(kong)氣(qi)質量總(zong)體(ti)(ti)較好(hao)。中國環境(jing)監(jian)測(ce)(ce)(ce)總(zong)站(zhan)還對比了武(wu)漢(han)市市控監(jian)測(ce)(ce)(ce)點位(wei)的情況(kuang)，與國控點位(wei)濃(nong)度(du)(du)監(jian)測(ce)(ce)(ce)結果基本吻合。
