摘 要:采用1 m^(3)气候箱模拟室内环境,在23℃和35℃条件下,便携式气质联用法和分光光度法测定并研究了两类复合木地板中甲醛和挥发性有机化合物(VOCs)的浓度及释放规律,并对污染物释放浓度进行了风险评估。结果表明:便携式气质联用能快速、准确测出VOCs的质量浓度;分光光度法测定的甲醛为复合木地板中主要污染物,其单因子影响最大。温度为35℃时,两类木地板均存在甲醛超标,超标倍数分别为1.1倍和1.3倍, 28 d后污染风险依然存在。The 1 m^(3) chamber was used to simulate the indoor environment. The concentration and release of formaldehyde and volatile organic compounds(VOCs) in two kinds of composite wood flooring were determined by portable GC-MS and spectrophotometry under both 23 ℃ and 35 ℃Conditions. Meanwhile, risk assessment of pollutant release concentration was also evaluated. The results show that the portable GC-MS is robust to quickly and accurately measure the mass concentration of VOCs. Formaldehyde determined by spectrophotometry is the main pollutant in composite wood flooring, and its single factor has the greatest impact. When the temperature is 35 ℃,the formaldehyde content of two kinds of wood floors exceed the standard 1.1 times and 1.3 times respectively. The risk of contamination remains after 28 days.
关 键 词:气候箱法 挥发性有机化合物 室内空气品质 综合评估
