不是孩子体质差容易生病,而是你家的水质影响了孩子的抵抗力


现在水质安全一直是大家所担心的问题,被污染的水中,可能会含有化合物、有机毒物等,这些物质不但会威胁水生生物的生命,也会影响饮用水源,影响人类的饮水健康,尤其是对孩子的伤害更大!


1、为什么污染水对孩子的伤害更大?

孩子属高风险人群,或称敏感人群。儿童体内含水量高于成水机会多,一旦水受到污染,接触水中化学污染物机会多,对化学污染物的吸收率高;而组织器官又处于快速生长发育过程中,对化学污染物毒性作用特别敏感,同样暴露水平可能对成年人不产生影响,但却可能导致儿年人,单位体重接触童的健康损害。

2、了解一下现在的水里还有什么

目前为止,自来水依然是我国城市居民最主要的生活用水来源。只要稍微了解一下自来水工艺:沉淀、过滤、消毒、出厂、通过管网送到千家万户。

这种近百年来没有改变的工艺,已经处理不了现在水中由工业、农业、养殖、生活方式等产生的污染物。

这种状况只相当于对原水进行了一定程度的预处理,更多的有害物质还在自来水中,我们就不能不为水污染引起的健康问题而揪心。


3、威胁儿童健康的主要水污染

国内外大量流行病学调查研究表明,水中一些敏感指标已对儿童健康构成潜在威胁。如,铅、镉、锰、铝、硝酸盐氮。

①铅

国际癌症研究中心列为致癌物2B组。

水中铅污染,儿童摄入铅后,有40%被吸收,而成人只吸收10%;铅污染影响儿童发育,尤其影响脑发育,使儿童智商下降,对儿童发育产生不可逆损害。

 

②镉

国际癌症研究中心列为致癌物2A组。

长期低水平镉污染影响肾脏及骨骼、免疫的正常功能发育,对儿童少年高级神经活动如学习、记忆造成损害。


③锰

水中锰污染致儿童体内锰含量的增加,影响其注意力和反应速度,降低儿童的学习记忆能力和手部运动的协调性。


④铝

损害中枢神经系统降低认知能力,导致老年痴呆。


⑤硝酸盐氮

婴儿高铁血红蛋白症,儿童智力下降,听力视觉迟钝。


4、喝热水是不是就安全放心了呢?

①水烧开只能杀死细菌

很久以前喝凉水是常事儿,爸妈总会说“这样不行,肚子里会生虫的”!而一般的卫生常识也说:自来水要烧开了经过消毒才能喝。

那个时候的水源只是有些细菌污染。

所以说,把自来水烧开,就可以把水中的细菌杀死,水喝到肚子里就不会拉稀,这就是喝开水的基本原理。

②水中的农药、激素是无法用烧开来处理的

现在,水里面含有更多的污染,而这些污染靠把水烧开是处理不了的。


5、我国与发达国家饮用水标准的差异

以美国为例,美国国家饮用水水质标准依据包括儿童等敏感人群在内的所有人群每人每天饮用2升水,70年终生安全这一重要因素而制订。

我国GB5749-2006生活饮用水卫生标准由于水处理技术、经济等国情,在考虑敏感人群这一重要因素方面宽于美国要求,对儿童健康存在不安全隐患。

作为芸芸众生中的一员,除了我们自己和家人孩子、孩子的健康是重要,没有人会更关心我们的健康了,用净水器就是对自己和家人的健康负责。
