目的 了解焦化作业环境空气中颗粒物的污染特征,为制定焦炉逸散物职业接触限值提供科学依据.方法 选取武汉市某焦化厂的附属、炉底、炉侧和炉顶作业区,测定一氧化碳(CO)、二氧化硫(SO2)、苯可溶物(BSM)、苯系物(包括苯、甲苯和二甲苯)、PM10、PM2.5,PM10和PM2.5上16种多环芳烃(PAHs)浓度,分析颗粒物与颗粒物上载带PAHs、BSM以及焦炉逸散物其他组分的关系.结果 焦化作业区空气中CO、SO2、BSM、苯系物、PM10和PM2.5及它们载带总PAHs浓度呈现附属＜炉底＜炉侧＜炉顶的趋势,趋势有统计学意义(P趋势＜0.05).PM2.5,占PM10的比例在焦化作业区间差异无统计学意义(P＞0.05).PM10与CO、SO2、苯、苯系物和BSM呈正相关,相关系数分别为0.705、0.823、0.664、0.624和0.734(P＜0.05)；PM2.5与CO、SO2、苯、苯系物和BSM呈正相关,相关系数分别为0.635、0.916、0.680、0.553和0.726(P＜0.05);BSM与苯呈正相关,相关系数为0.698(P＜0.05).PM10和PM2.5上PAHs的环数分布在各作业区相同.各作业区空气中PM10和PM2.5上PAHs的总苯并(a)芘等当量浓度中位数的差异无统计学意义(P＞0.05).结论 焦化厂空气中颗粒物浓度与焦炉逸散物中其他组分相关,单位体积空气中PM10和PM2.5上PAHs的含量和种类相似.
目的 瞭解焦化作業環境空氣中顆粒物的汙染特徵,為製定焦爐逸散物職業接觸限值提供科學依據.方法 選取武漢市某焦化廠的附屬、爐底、爐側和爐頂作業區,測定一氧化碳(CO)、二氧化硫(SO2)、苯可溶物(BSM)、苯繫物(包括苯、甲苯和二甲苯)、PM10、PM2.5,PM10和PM2.5上16種多環芳烴(PAHs)濃度,分析顆粒物與顆粒物上載帶PAHs、BSM以及焦爐逸散物其他組分的關繫.結果 焦化作業區空氣中CO、SO2、BSM、苯繫物、PM10和PM2.5及它們載帶總PAHs濃度呈現附屬＜爐底＜爐側＜爐頂的趨勢,趨勢有統計學意義(P趨勢＜0.05).PM2.5,佔PM10的比例在焦化作業區間差異無統計學意義(P＞0.05).PM10與CO、SO2、苯、苯繫物和BSM呈正相關,相關繫數分彆為0.705、0.823、0.664、0.624和0.734(P＜0.05)；PM2.5與CO、SO2、苯、苯繫物和BSM呈正相關,相關繫數分彆為0.635、0.916、0.680、0.553和0.726(P＜0.05);BSM與苯呈正相關,相關繫數為0.698(P＜0.05).PM10和PM2.5上PAHs的環數分佈在各作業區相同.各作業區空氣中PM10和PM2.5上PAHs的總苯併(a)芘等噹量濃度中位數的差異無統計學意義(P＞0.05).結論 焦化廠空氣中顆粒物濃度與焦爐逸散物中其他組分相關,單位體積空氣中PM10和PM2.5上PAHs的含量和種類相似.

Objective To explore the characteristics of particulate matter pollution in coke oven plant,so as to provide scientific data for establishing occupational exposure limits for coke oven emissions.Methods Concentrations of CO,SO2,BSM,BTEX (concentrations of benzene,toluene and xylene were determined in this study),PM10,PM2.5,16 selected PAHs in PM10 and PM2.5 were determined in the work environment of a coke oven plant in Wuhan.The work environment was divided into the adjunct area,the bottom of,the side of and the top of coke oven.Results The concentrations of CO,SO2,BSM,BETX,PM10,PM2.5,PAHs in PM10 and PM2.5 were significantly related to working environmental categories,respectively,and were increasing as the adjunct area＜ bottom＜ side＜ top (Pmend＜0.05).PM10 was statistically significantly correlated with CO,SO2,benzene,BTEX and BSM (0.705,0.823,0.664,0.624 and 0.734,respectively).PM2.5 was statistically significantly correlated with CO,SO2,benzene,BTEX and BSM (0.635,0.916,0.680,0.553 and 0.726,respectively).BSM was statistically significantly correlated with benzene (0.689).The ratios of PM2.5 to PM10 between different work environments were not significantly different in one-way ANOVA (P＞0.05).The distribution of aromatic rings and the concentrations of total benzo[a] pyrene equivalents in PM10 and PM2.5 were not statistically different between work environments.Conclusion The concentrations of particulate matter was related with other contents of coke oven emissions in coke work environment,and the contents and types of PAHs in PM10 and PM2.5 were similar.
