目的:了解家具城室内环境游离性甲醛暴露情况。方法:对大理市2家家具城室内游离性甲醛含量进行检测,同时对家具城从业人员与消费者的装修污染认知水平及主观感觉、呼吸道症状发生率进行调查。结果:家具城内环境游离性甲醛平均浓度为(0·082±0·026)mg/m3,超出国家规定的居室内空气中甲醛最高容许浓度标准(0·08mg/m3),样品超标率为31·25%;游离性甲醛暴露水平,家具城内环境4个角落检测数据显著高于正厅和室外对照(P<0·05);家具城从业人员与消费者对装修污染的认识存在偏差,甚至误解;从业人员主观感受、呼吸症状发生率与消费者相比,差异无统计学意义(P>0·05)。结论:加强家具城室内环境卫生监督与监测,通风排毒减少甲醛污染;改进家具加工木制板材工艺,减少甲醛释放;做好职业环境健康促进,增强从业人员与消费者的装修污染意识。
