全國城市霧霾排行榜單-你所在城市排名多少

霧霾是霧和霾的混合物，早晚濕度大時，霧的成分多。白天濕度小時，霾占據(jù)主力，相對濕度在80%到90%之間。其中霧是自然天氣現(xiàn)象，空氣中水汽氤氳。雖然以灰塵作為凝結(jié)核，但總體無毒無害;霾的核心物質(zhì)是懸浮在空氣中的煙、灰塵等物質(zhì)，空氣相對濕度低于80%，顏色發(fā)黃。氣體能直接進入并粘附在人體下呼吸道和肺葉中，對人體健康有傷害。霧霾天氣的形成是主要是人為的環(huán)境污染，再加上氣溫低、風(fēng)小等自然條件導(dǎo)致污染物不易擴散。中國霧霾空氣質(zhì)量最差10個城市：保定、邢臺、石家莊、唐山、邯鄲、衡水、濟南、廊坊、鄭州、天津，河北省一省就占據(jù)了7席，保定、邢臺、石家莊、唐山、邯鄲、衡水、廊坊均出現(xiàn)在中國空氣質(zhì)量最差10個城市榜單中，此外山東濟南、天津為10城中的另外兩城。2016中國城市霧霾排行榜單呼吸困城市排名PM2.5年均值難指數(shù)(微克/立方米)1邢臺131.42保定127.23石家莊122.64邯鄲114.25衡水107.66德州1067菏澤100.68聊城99.89廊坊99.310唐山98.411安陽94.612淄博94.613萊蕪93.414宜昌92.115臨沂91.916濟南9117荊州88.818濟寧88.219滄州8820鄭州87.621棗莊87.622平頂山87.323壽光86.324天津85.825濱州85.426北京83.227開封82.228合肥8029武漢79.530焦作78.231濰坊78.232東營77.333泰安7734西安75.735三門峽75.536長沙7537渭南74.238南京73.739自貢73.140成都72.841洛陽72.842哈爾濱72.543江陰71.644咸陽71.645株洲71.646湘潭71.447泰州7148沈陽70.949庫爾勒70.150鞍山69.951寶雞69.552南充69.453句容68.954常德68.655陽泉68.156太原67.757宿遷67.658蕪湖67.559長治67.260馬鞍山6761徐州66.762淮安66.563銅川66.364無錫66.365常州66.266鎮(zhèn)江65.867柳州65.768宜賓65.269瀘州64.770長春64.671金華64.272蘇州64.173張家港63.574揚州63.275溧陽6376烏魯木齊62.977重慶62.878湖州62.879平度62.780膠南62.581萊州62.482日照62.283西寧62.184瓦房店6285臨汾6286錦州6287臨安6288招遠61.589桂林61.290萊西61.191諸暨6192杭州60.993紹興60.794義烏60.495連云港60.496南通60.397德陽60.398富陽60.299張家界59.8100吉林59.4101章丘59102秦皇島59103金壇58.9104蘭州58.8105吳江58.7106宜興57.7107鹽城57.5108牡丹江57.3109岳陽57.3110盤錦56.9111膠州56.9112太倉56.6113遵義56.3114本溪56.3115撫順56.2116嘉興56117綿陽54.9118葫蘆島54.5119乳山54.1120青島53.9121承德53.5122海門53.5123包頭53.4124衢州53.2125肇慶53.1126昆山53.1127大連*53128常熟52.9129上海52.2130文登51.4131即墨51132石嘴山50.1133南昌49.8134煙臺49135揭陽49136蓬萊49137延安48.7138潮州47.9139韶關(guān)47.9140南寧47.6141丹東47.6142赤峰47.5143銀川47.4144廣州47.4145臺州46.3146榮成46147寧波45.7148溫州45.7149貴陽45.5150東莞44.1151呼和浩特44152佛山44153麗水43.7154大同43.2155江門43.1156九江42.9157大慶42.9158清遠41.2159金昌41.2160威海40.7161河源40.2162營口39.4163攀枝花39164汕頭38.8165梅州38.5166克拉瑪依38.5167茂名37.9168中山37.6169齊齊哈爾37.2170廈門36.3171嘉峪關(guān)36.2172陽江36.1173曲靖34.8174惠州34.6175張家口34.3176珠海33.8177北海32.8178汕尾32.7179深圳32.5180云浮
