江西省室内空气总挥发性有机物污染现状分析及变化规律研究

首次系统地分析了江西省室内空气总挥发性有机物污染现状。结果表明全省及9个设区市室内环境空气中总挥发性有机物造成一定污染，在全省抽测的456个样本中，空气总挥发性有机物范围为0．01mg／m^2-126．35mg／m^3，平均值为1．83mg／m^3,超标率为36．2％。并研究探讨了江西省室内空气总挥发性有机物变化规律为：家居卧室、家居客厅、家居厨房空气总挥发性有机物污染程度相对较高；随着装修时间的推移，空气总挥发性有机物平均浓度和超标率总体呈下降趋势，但在25个月-48个月时出现反弹；室内空气总挥发性有机物污染随着装修档次的提高而加剧。
