柳州市宾馆(酒店)公共用品中荧光剂对人体健康危害的风险评价

Risk assessment of human health hazards caused by fluorescent agents in public goods in hotels of Liuzhou City

目的了解柳州市宾馆(酒店)公共用品中荧光增白剂对人体健康危害的风险状况。方法随机采集柳州市宾馆(酒店)的公共用品,检测pH值和7种荧光剂含量,分析pH值与荧光剂的相关性,评价荧光剂对人体健康危害的风险性。结果公共用品中检出3种荧光剂FWA71、FWA85和FWA351,荧光剂FWA71检出率为100.0%,FWA85和FWA351检出率分别为30.3%和60.2%;一件样品可同时含有至少2种荧光增白剂。公共用品中残留的荧光剂含量大小与pH值高低无相关性;每位旅客每次入住酒店,公共用品中的荧光剂对人体健康的危害存在中等风险等级。结论柳州市宾馆(酒店)公共用品中荧光剂对人体健康危害存在中等风险等级。在洗涤过程减少洗涤剂的使用量,软化、过滤洗涤用水,控制洗涤温度,可以有效增加用品的白度和洁净感,减少荧光剂的残留量,降低荧光增白剂对人体健康危害的风险性。

Objective To understand the risk status of human health hazards caused by fluorescent agents in public goods in hotels of Liuzhou City.Methods The public goods in hotels of Liuzhou City were randomly collected,to measure the pH value and the contents of seven kinds of fluorescent agents.The correlation between pH value and fluorescent agents was analyzed,and the risk of fluorescent agents to human health hazards was evaluated.Results Three kinds of fluorescent agents,including FWA71,FWA85 and FWA351,were detected in public goods.The detection rate of fluorescent agent FWA71 was 100.0%,and the detection rates of FWA85 and FWA351 were 30.3%and 60.2%,respectively.One sample could contain two or more fluorescent whitening agents at the same time.There was no correlation between the amount of residual fluorescent agents in public goods and the pH value.While each passenger stayed in the hotel,the hazard of fluorescent agents in public goods to human health was at a medium risk level.Conclusion There is a moderate risk level of fluorescent agents in public goods of hotels to human health in Liuzhou City.Reducing the use of detergent in the washing process,softening and filtering the washing water,and controlling the washing temperature can effectively increase the whiteness and cleanliness of the products,reduce the residual amount of fluorescent agents,and reduce the risk of fluorescent whitening agents on human health.
