摘要
采用顶空-气相色谱法对40批次塑料包书皮中的17种挥发性有机物进行检测,有23批次样品被检出含有挥发性有机物,其中13批次检出甲苯,5批次检出1,2-二氯乙烷。根据塑料包书皮中甲苯和1,2-二氯乙烷对人体的伤害特点,建立了经呼吸和皮肤接触两种暴露途径下的暴露量计算模型,并对其潜在的健康风险进行初步评价。
Forty kinds of dust jackets have been collected, and the concentrations of seventeen kinds of volatile organic compounds have been determinated by headspace-gas chromatography. As a result, volatile organic compounds were found in 23 samples. Among them, toluene was found in 13 samples, and 1,2-dichloroethane was found in 5 samples. According to the exposure characteristics of toluene and 1,2-dichloromethane contained in the dust jackets, the calculation model was established, which can be used to calculate the toluene and 1,2-dichloromethane exposure levels from dust jacket via inhalation and skin exposure routes. At last, the potential health risks were evaluated preliminarily.
