摘要 目的以低浓度苯系物职业接触人群为研究对象,分析低浓度苯接触剂量与尿中反一反式黏糠酸(ttMA)、苯巯基尿酸(S-PMA)、8-羟基脱氧鸟苷(8-OHdG)水平关系。方法以7家企业120名苯系物接触工人为研究对象(接触组),对照组为同企业共84名不接触苯系物的行政和后勤工作人员。热解析气相色谱法测定工作环境中苯、甲苯和二甲苯浓度,高效液相色谱三重串联四级杆质谱(HPLC—MS—MS)测定职业接触人群尿中ttMA、S—PMA和8-OHdG含量,并进行统计分析。结果在作业场所苯平均加权浓度(C_TWA)0.25~5.98mg/m3时,尿中ttMA、S—PMA与空气中苯浓度均呈相关性(r2=0.8759,r2=0.7497)。低浓度苯系物(C_TWA〈6mg/m3)、甚至低于3.25mg/m。的苯也对职业苯接触人员造成遗传损伤,且损伤程度有随苯浓度的增高而增强的趋势;尿中8-OHdG含量与苯接触浓度呈一定的剂量一反应关系(r2=0.181、P〈0.01)。结论尿中ttMA、S-PMA与空气中苯浓度均具有较高的相关性,可作为低浓度苯职业性接触生物监测的接触标记物;低浓度苯具有遗传损伤效应,尿中8-OHdG可作为苯致遗传损伤的效应标志物。未发现混杂接触限值以内的甲苯、二甲苯(C_TWA〈50mg/m3)对苯遗传损伤产生协同或拮抗作用。
