摘　　要：为了阐明包装材料溶剂残留物的暴露水平及对人产生的潜在健康风险,从市场上采集了3种包装纸,采用气相顶空色谱-质谱联用(HS/GC-MS)法对样本中溶剂残留物的质量进行测定;根据包装纸中溶剂物残留物对人体的伤害特点,建立了经呼吸和经皮肤途径下的暴露量计算模型和风险表征模型,研究包装纸中溶剂残留物的暴露水平,并对其潜在健康风险进行评价。结果表明:该方法的回收率在84.8%~107.0%之间,检出限在0.001~0.258 mg/m^(2)之间,相对标准偏差(RSD)小于5%;样品1包装纸中丁酮的残留量为0.4543 mg/kg;样品2包装纸中乙酸乙酯的残留量为0.5074 mg/kg;样品3包装纸中丙酮的残留量为0.0975 mg/kg;经皮肤暴露是有机残留物voc对人体产生健康危害的主要途径;本次监测的纸包装纸中有机挥发物为“可容许风险”。In order to clarify the exposure levels of solvent residues in wrapping materials and the potential health risks to humans,three types of wrapping paper was collected from the market,and the solvent residues in the samples were analyzed by headspace gas chromatography-mass spectrometry(HS/GC-MS).The quality of the substance was measured.Based on the damage characteristics of solvent residues in wrapping paper to humans,a respiratory and transdermal exposure calculation model and risk characterization model were established to study the exposure levels of solvent residues in packaging paper and evaluate their potential health risks.The results showed that,the recovery rate of this method was between 84.8%and 107.0%,the detection limit was between 0.001 mg·m-2 and 0.258 mg·m-2,and the relative standard deviation(RSD)was less than 5%;The residual amount of ketone was 0.4543 mg·kg-1;the residual amount of ethyl acetate in the wrapping paper of sample was 0.5074 mg·kg-1;The residual amount of acetone in the wrapping paper of sample 3 was 0.0975 mg·kg-1;The organic residue was exposed through skin exposure;The organic volatiles in the paper wrapping paper monitored this time were"allowable risks".
