北京清华附中丰台学校小学部疑现毒跑道

2015-12-13 10:03:05   中国新闻网

据中国之声《新闻晚高峰》报道,近日,清华大学附属中学丰台学校小学部多位家长向中国之声反映称,至少有38名学生近期出现头晕、恶心等身体异常,不少学生血液和尿液中的毒物分析检测出苯甲酸。家长因此怀疑这和学校前不久刚铺设完成的塑胶跑道有关,要求学校铲除跑道。但校方称,跑道各项指标检测合格,没有确切证据下不能铲除跑道。目前家长和学校双方僵持不下。

杨女士的儿子今年7岁,在清华附中丰台学校小学部上一年级。今年十月以来,她的儿子身体状况就不断出现异常。在接受采访时,杨女士哽咽着告诉记者,现在孩子还这么小,每个家庭都有一个孩子,作为父母心里肯定接受不了,教室是新装修的,操场是新铺的,现在问题已经出现了,校方还不积极去解决这些事情。

杨女士带孩子到军事医学科学院附属307医院做了检查,医院毒检室检测报告显示,经过毒物分析,孩子的血液和尿液中均检测到了苯甲酸。孩子血液当中含苯甲酸是0.07微克每毫升,尿液含0.2微克每毫升。杨女士说孩子以前也没有这样的症状,而且前段时间头晕头痛,恶心胸闷气短,以前孩子的心电图是正常的,北大妇儿做的时候,就窦性心律不齐,ST段改变,那边医生说可能是空气污染。

和杨女士的孩子一样,其他家长也陆续发现孩子近期身体不舒服。

有家长向记者反映异常出现在十月份左右,症状是经常头疼,肚子疼,去做检查,结果是血液和尿液中含苯甲酸。

还有家长反映说施工那段时间孩子经常会流鼻血,头晕,这很反常,因为之前几乎没流过鼻血。当时特别担心,检查发现是有苯甲酸。

苯甲酸是一种化学物质,多用于医药、染料载体、增塑剂、香料和食品防腐剂等的生产,也用于醇酸树脂涂料的性能改进。对微生物有毒性。

根据学生家长的统计,目前至少有38名学生身体出现了异常。在学校门口,多位家长向记者提供了307医院毒检室的检测报告,以及检验科的血液检测报告单。检测报告显示,除了孩子的血液和尿液中含有苯甲酸,其他肌酐和二氧化碳结合力数值呈现下降态势,尿潜血定性呈弱阳。

这些检测结果意味着什么?截至记者发稿前,记者未能就此结果,采访到307医院的儿科专家发表意见。

不过,郑州大学公共卫生学院教授、博士生导师崔留欣指出,苯甲酸是集体代谢当中好多东西的产物,不一定是跑道弄的。膳食当中的或者药物都可以,没有必然的因果联系。苯甲酸对肝肾功能,少量的没有关系,大量的有关系。绝对不可以盲目地武断地把操场上测到的,和人体内的挂上钩,这个问题很复杂。要做的工作太多,不是说仅凭一个数据就能把跑道和人体联系起来的。

记者也采访了多位血液科专家。中国医师协会输血科医师分会常委吕毅说,虽然检测结果并不能说明孩子的肝肾脏受到了损伤,但造成身体异常的现象应该引起重视和关注。但是他这种亚健康,自己感到不舒服。这种雾霾天气,你能查出来每一天对我们的肺功能受到了多大影响吗?这是检测不出来的。”

北京中医药大学东方医院检验科主任寿好长认为,苯甲酸,包括甲醛,它是一个累积效应,在人体里面,中毒不一定从化验指标中能分析出来。
