摘要
为探讨儿童地垫产品中不同挥发性有机物(VOCs)的浓度及对健康的影响,通过顶空-气相色谱质谱仪对儿童地垫中挥发性有机物进行筛查,采用气袋法研究不同材质、不同温度对儿童地垫中挥发性有机物释放浓度的影响,并运用蒙特卡洛模拟的方法对其进行健康风险评估.结果表明,地垫中含有多种具有一定毒性的VOCs,这些有机物的释放与材质关系不大,但是与温度有着显著的相关性,温度越高,释放浓度越大.当运用蒙特卡洛方法对儿童地垫中甲苯、二甲苯、正丁醇、丙酮、2-丁酮5种物质进行吸入性风险评估时,在95%的置信区间范围内,正丁醇的风险值为1.65,超过了风险值,其他物质的风险值均<1,健康风险较小.
Abstract
To study the concentrations of different volatile organic compounds(VOCs)in children's play mats and their effects on health,the headspace-gas chromatography mass spectrometer was used to identify unknown chemi-cals in the play mats,and the gas sample bag method was used to study the concentrations of different chemicals released under different temperatures and materials.Furthermore,a risk assessment of the various VOCs in children's play mats was conducted using the Monte Carlo simulation method.The results showed that a variety of VOCs with various toxicities were present in play mats.The release of VOCs was not affected greatly by the material,but it was significantly influenced by the temperature.The concentrations of the chemicals increased as the temperature rose.The Monte Carlo method was used to assess the inhalation risks of toluene,xylene,n-butanol,acetone,and 2-butanone from children's play mats.The risk value of n-butanol was 1.65,which exceeds the ac-ceptable risk threshold within the 95%confidence interval.The risk values of other substances were less than 1,in-dicating a low level of health risks.
