摘要
以PU漆、水性漆涂饰的薄木贴面刨花板和刨花板素板3种板材为研究对象,使用GC-MS对板材释放的苯系物进行检测,分析苯系物的浓度水平、组成特征和变化规律,并依据美国环保署的健康风险模型对两种(康风险模型对两种)油漆涂饰的板材释放的BTEX(苯、甲苯、乙苯、对二甲苯)和苯乙烯的人体健康风险进行评价。结果表明:PU漆饰刨花板释放的15种苯系物总质量浓度为125.18μg·m^-3,其中BTEX质量浓度为45.27μg·m^-3,约占总质量浓度的36.16%,BTEX和苯乙烯对人体的非致癌风险商值在2.51E-04至5.35E-01,危害指数为5.90E-01,对暴露人群尚无明显非致癌风险,苯的致癌风险值为1.25E-04,超过致癌风险值上限,对暴露人群具有显著的致癌风险。水性漆饰刨花板释放的12种苯系物总质量浓度为58.8μg·m^-3,其中BTEX质量浓度为38.16μg·m^-3,约占总质量浓度的64.81%,BTEX和苯乙烯对人体的非致癌风险商值在3.53E-03至4.29E-01,危害指数为4.80E-01,对暴露人群无明显非致癌风险,苯的致癌风险值为1E-04,达致癌风险值上限,对暴露人群具有显著的致癌风险。因此,应提高对室内漆饰板式家具苯系物致癌风险的监控与评估。
Two kinds of paint lacquered veneer decorating particleboard and normal particleboard were used as the research object. The benzene series released from the lacquered board was detected by GC-MS. The concentration level, composition characteristics and change characteristics of benzene series were studied, and the health risk in accordance with documents of the environmental protection agency, US was analyzed. The model evaluates the human health risks of BTEX(benzene, toluene, ethylbenzene, p-xylene) and styrene released from two kinds of paint lacquered particalboard. The results showed that the total concentration of 15 benzene series released from PU lacquer particleboard was 125.18 μg·m^-3, and the mass concentration of BTEX was 45.27 μg·m^-3, accounting for 36.16% of the total mass concentration. BTEX and styrene has non-carcinogenic risk for human body. The non-carcinogenic risk value is 2.51 E-04 to5.35 E-01, the hazard index is 5.90 E-01, there is no obvious non-carcinogenic risk to the exposed population, and the carcinogenic risk value of benzene is 1.25 E-04, which exceeds the upper limit of carcinogenic risk. It has a significant cancer risk to exposed populations.The total concentration of 12 benzene series released from water-based paint particleboard was 58.8 μg·m^-3, and the mass concentration of BTEX was 38.16 μg·m^-3, accounting for 64.81% of the total mass concentration. BTEX and styrene has non-carcinogenic risk for human body. The non-carcinogenic risk value is between 3.53 E-03 and 4.29 E-01, and the hazard index is 4.80 E-01. There is no obvious non-carcinogenic risk to the exposed population. The carcinogenic risk value of benzene is 1 E-04, which reaches the upper limit of carcinogenic risk. It has a significant cancer risk to exposed populations. The monitoring and evaluation of the carcinogenic risk of benzene series in indoor lacquered plate-type furniture should be improved.
