【題目】為減少霧霾天氣的發(fā)生,下列措施可行的是

A.集中布局有污染的工業(yè)B.大力發(fā)展私家轎車

C.冬季取暖“煤改電”、“煤改氣”D.擴(kuò)大城市面積

【答案】C

【解析】

霧霾天氣是一種大氣污染狀態(tài),霧霾是對(duì)大氣中各種懸浮顆粒物含量超標(biāo)的籠統(tǒng)表述,尤其是PM2.5(空氣動(dòng)力學(xué)當(dāng)量直徑小于等于2.5微米的顆粒物)被認(rèn)為是造成霧霾天氣的"元兇"。隨著空氣質(zhì)量的惡化,陰霾天氣現(xiàn)象出現(xiàn)增多,危害加重。中國(guó)不少地區(qū)把陰霾天氣現(xiàn)象并入霧一起作為災(zāi)害性天氣預(yù)警預(yù)報(bào)。統(tǒng)稱為"霧霾天氣"

集中布局有污染的工業(yè),排放的總污染物未減少,A排除;大力發(fā)展私家轎車、擴(kuò)大城市面積會(huì)導(dǎo)致人類活動(dòng)排放的污染物增加,加重大氣污染,B、D排除;冬季取暖“煤改電”、“煤改氣”,減少了煙塵的排放,C符合題意;故選:C。
