【摘要】：[目的]探討裝修居室室內(nèi)空氣揮發(fā)性有機物污染狀況及其健康危害。[方法]選擇唐山市市區(qū)在2001～2006年裝修的152戶裝修居室,進行室內(nèi)空氣甲醛、苯、甲苯和二甲苯濃度的檢測,并對留居者進行自覺癥狀問卷調查。[結果]裝修后時間在半年內(nèi)的居室室內(nèi)甲醛濃度為0.098mg/m3,超標率為47.06%,隨著裝修時間的延長甲醛濃度有下降的趨勢,裝修后不同時間組的甲醛濃度差異有統(tǒng)計學意義(P=0.0076)。裝修時間≤1年的和�e1年的居室苯超標率分別為88.89%和30.77%,而甲苯和二甲苯濃度均無超標,兩組苯和二甲苯濃度差異均有統(tǒng)計學意義(P值分別為0.0009和0.0302)�？刂颇挲g、性別和吸煙等混雜因素后,甲醛和苯濃度超標組和不超標組的留居者上呼吸道黏膜、皮膚黏膜刺激癥狀、眼睛刺激癥狀和神經(jīng)衰弱癥狀的發(fā)生率差異均無統(tǒng)計學意義。每日居室停留時間�e12h的40歲以上年齡的留居者的皮膚刺激癥狀發(fā)生率較高,差異有統(tǒng)計學意義(χ2=4.7303,P=0.0296)。[結論]唐山市居室室內(nèi)裝修所致?lián)]發(fā)性有機物污染狀況不容忽視。留居者長時間暴露VOCs,皮膚刺激癥狀的發(fā)生率較高。
[Abstract]:[objective] to study the pollution of indoor air volatile organic compounds (VOCs) and its health hazard. [methods] 152 decorated rooms in Tangshan city from 2001 to 2006 were selected to detect the concentrations of formaldehyde, benzene, toluene and xylene in indoor air. [results] the indoor formaldehyde concentration was 0.098 mg / m ~ (3) and the rate of exceeding the standard was 47.06. With the prolongation of decoration time, the concentration of formaldehyde decreased, and the difference of formaldehyde concentration in different time groups after decoration was statistically significant (P _ (0.0076). The rates of benzene exceeding the standard were 88.89% and 30.77% in the rooms with decoration time 鈮，
