央视暗访学校跑道施工队:三无塑胶颗粒加三无胶水

2016-06-23 09:37:28   澎湃新闻网

校长:验收是由他们专门机构来验收,跟校方。

记者:你来参与吗?

校长:我们副校长跟着参与。

记者:教委有没有参加到最后跑道的验收工作?

张子连:应该参加了。

记者:那有没有一些验收签字报告等等这一系列手续?

张子连:这都有。

记者:我在哪里能看到验收的报告?

张子连:验收报告应该能够看到。一会咱们可以看看,应该在我们贾老师手上。他一会要是过来就能给您看到。

但是,记者在平谷区教委等待了5个小时之后,直到离开也没有见到这位新闻发言人所提到的贾老师。在记者的再三要求之下,平谷区第六小学向记者出示了一份中国检验检疫科学研究院综合检测中心的检测报告,检测项目包括苯、甲苯、二甲苯、铬、汞、铅、镉。该中心的检测结论显示:第一,经现场验收,施工内容、工程量符合设计及施工质量验收规范,第二、验收过程中发现塑胶面层有气味,已现场取样送检,检测结果未出。

“毒跑道”黑色产业链:视国家标准如“空气”昧着良心坑孩子!

虽然塑胶跑道目前暂时得出了这样的监测结论,但在平谷区第六小学的操场改造工程合同上,记者始终没有看到跑道使用的塑胶材料究竟是什么,为什么塑胶跑道会散发刺鼻的气味呢?记者带着问题找到了中国聚氨酯工业协会异氰酸酯专业委员会,秘书长李建波给出了他的答案。

中国聚氨酯工业协会副秘书长李建波:塑胶跑道用的比较多的有甲苯,有二甲苯,还有一些乙酸乙酯,那么这些溶剂它的危害性是有大有小。其中甲苯的危害性可能是最大的,二甲苯是次之,乙酸乙酯这些溶剂相对来说危害性就要小一些。所以,如果它使用的这些原料各方面质量不是很好的时候,所以对于溶剂的添加量,可能就会比正常的溶剂添加量要多。那么在这种情况下,跑道的气味,包括它的危害性要比正常的情况大。

李建波告诉记者,塑胶跑道铺设之后,各种有毒有害物质一旦超标,将会导致头晕、恶心、呕吐、呼吸困难等症状。所以,早在1993年我国就出台了相关的标准,2011年又将旧标准进行了完善。郭龙,《合成材料跑道面层》GB/T14833-2011第一起草人,他告诉记者,2011年中国标准化委员会和国家体育总局同时出台的标准,都在内容上有了新变化,其中重要的一项就是增加了环保性能要求及测定方法,并对有毒有害物质进行了具体的规定。其中,苯,每千克小于等于0.05克,甲苯和二甲苯总和,每千克小于等于0.05克,游离甲苯二异氰酸酯,每千克小于等于0.2克,重金属可溶性铅,每千克小于等于90毫克;可溶性镉,每千克小于等于10毫克,可溶性铬,每千克小于等于10毫克,可溶性汞,每千克小于等于2毫克。
