甲醛超标校方发风扇 规范作业甲醛何来?

2016-09-25 09:02:09   中国网

8月29日,学校将家具样品送至国家家具产品质量监督检验中心(广东)进行检测。9月9日,家具质量检测报告出来,结果显示甲醛释放量为1.1毫克每升,低于1.5毫克每升的国家标准。

9月1日,学校邀请广州质量监督检测研究院进行现场检测,三位学生代表参与了检测的全过程。9月12日检测报告出来,随机抽样的四间宿舍中,苯含量均低于国家标准,TVOC(总挥发性有机物)含量总体低于国家标准,而游离甲醛的含量分别为0.15、0.20、0.21、0.34,高于每立方米0.08毫克的国家标准。

广州质量监督检测研究院专家认为,游离甲醛的来源很多,如家具、墙面漆甚至衣服等都会产生游离甲醛,造成学生宿舍游离甲醛超标的主要原因是学生宿舍的承载量有限。专家建议,一是通风,这是最有效的解决办法;二是聘请专业公司处理游离甲醛。

为解决这栋学生宿舍空气质量问题,学校持续采取多种举措,如为每间宿舍配发绿植、茶叶、活性炭,减免10月1日前的电费等。9月19日,学校聘请了广州叶子环保科技有限公司采取光触媒技术处理游离甲醛。为了让同学们尽快安心入住,将拟三天完成的工期压减为一天。由于对作业困难、复杂程度等预判不足,原本预计20点处理完毕的工作延迟到了23时40分,致使学生们在楼外等候。

9月22日,在发生甲醛超标的广东财经大学“30栋”学生宿舍楼前,大量落地电风扇等待被发放,用以帮助宿舍内通风。

妥善安置更要找出源头

广东省室内环境卫生行业协会执行会长顾士明表示,光触媒是一种技术手段,是采用喷洒等方式,将一种名叫纳米二氧化碳的材料喷射在含甲醛的物质上,在光的作用下,确实能起到分解甲醛的作用。

但是,顾士明认为,除了通风措施外,当前最关键的是要找出甲醛超标的源头,因为有些材料甲醛的释放期可以长达20年。找出源头采取针对性措施才有利于保障学生健康。

目前,广东财经大学方面在尽力挖掘全校图书馆、学院教师工作室、校内空置宿舍等可住宿资源,为有需求的学生安排住宿,并向第30栋学生宿舍每名学生发放500元补助。

同时,学校将加快除甲醛和空气质量检测工作进度,督促专业公司和检测机构尽快做好相关工作,在权威检测报告出来之前,每天实时动态监测。另一方面,学校尚未接到有学生因为甲醛不适住院就医的报告,但学校门诊部将加强24小时值班,为有不适症状的学生及时就诊提供便利和医疗保障。
