“食脑虫”,又名福氏耐格里阿米巴原虫,是一种单细胞生物,通常存活于温暖的淡水中。它能通过鼻腔进入中枢神经系统,感染大脑,最终导致被感染者脑死亡。
感染“食脑虫”后,人们可能会出现严重头痛、发热、恶心和呕吐等症状。随后。人们可能还会颈部僵硬,癫痫发作,出现幻觉,甚至昏迷。据称,感染者一般在出现症状后的1至18天内死亡。
根据疾病控制与预防中心(CDC)的说法,“食脑虫”通常在土壤、温暖的湖泊、河流和温泉中被发现。它也可以在维护不善或未氯化的水池中以及从工厂排放的温水中发现。感染这种寄生虫的月份通常发生在7、8、9月份,因为那时,各处水位较低,水温较高。
CDC说,尽管食人脑的变形虫的感染很少见,但大多数是致命的。从2009年到2018年,美国仅报告了34次感染。在这些报告的病例中,有30人被娱乐设施的用水感染。
根据CDC的数据,从1962年到2018年,有145人被食人脑的变形虫感染,只有4人幸存。
另据报道,一旦确诊被食脑虫入侵引发感染,死亡率超过97%。据美国疾病预防控制中心数据,2009年至2018年之间,美国报告了34例该疾病感染。在大多数情况下,人们在娱乐用水过程中被感染,另有3例是人们在使用被污染的自来水进行鼻腔冲洗后被感染的。另1例是被在后院的滑梯上使用过被污染的自来水后感染该疾病。

密歇根州弗林特市的水危机。因为城市从休伦湖转变为弗林特河作为其水源,这座城市的饮用水被发现是铅含量高。这种水从来没有用联邦法律所要求的抗腐蚀添加剂处理过,因此腐蚀了铁水管道,并析出了铅。弗林特当然不是美国在2016年7月被污染水的唯一案例,匹兹堡的水和污水管理局通知他们,他们的自来水中含有10亿分之22的铅,这让许多匹兹堡居民感到震惊。这是法定上限的1.5倍。
生活在德克萨斯州布雷迪(Brady)的人们正在处理自来水中的镭。而不仅仅是不可接受的水平——比法律允许的水平高出9倍。铅暴露对儿童和孕妇最危险,因为它会影响大脑发育。然而,它也会损害神经、心脏和肾脏——而且每个人都很容易受到这些影响。铅中毒是渐进性的,没有明显的症状。

Calcium carbonate in human body fluids is too high (water is too hard), and will cause a large number of stone formation,
Calcium carbonate content is too low (water is too soft) will lead to the decline of human immunity, so the soft hardness of drinking water should be moderate.

对于这个现象,大多数网友的回答是“因为国外自来水干净,达到了饮用水标准,而国内水质不行“。虽然不明真相,但其实我一开始也这样认为。我国很早就出台了居民饮用水相关标准,并且在2007年7月1日,在原有标准基础上,国家标准委和卫生部联合发布了《生活饮用水卫生标准》(GB 5749-2006)(下称“新标准”),进一步修订强制性国家标准和13项生活饮用水卫生检验国家标准。
内容很多无法详述,但有几点核心内容我们可以了解。“新标准”中有一项叫做“常规指标”,能反映生活饮用水水质基本状况的水质指标。“常规指标”包含微生物、毒理指标、化学指标和放射性。简单来说,微生物指细菌;毒理指标包含重金属、无机物、有机物等等;化学指标指的是颜色、气味、pH和部分金属、溶解性固体等等,......
从这一项来看,我国饮水用标准对各项有害物质有着非常详细的定义和规定。并且“新标准”第4项“生活饮用水水质卫生要求”部分规定如下:
4.1 生活饮用水水质应符合下列基本要求,保证用户饮用安全。
4.1.1 生活饮用水中不得含有病原微生物。
4.1.2 生活饮用水中化学物质不得危害人体健康。
4.1.3 生活饮用水中放射性物质不得危害人体健康。
4.1.4生活饮用水的感官性状良好。
4.1.5 生活饮用水应经消毒处理。
从以上这些描述可以得出一个结论,如果自来水能完全符合“新标准”,直接饮用对健康没有危害。
值得一提的是,针对“国外自来水干净,饮用标准高”这种观点,我国在指定新版饮用水标准时,已经实现饮用水标准与国际接轨。新标准水质项目和指标值的选择,充分考虑了我国实际情况,并参考了世界卫生组织的《饮用水水质准则》以及欧盟、美国、俄罗斯和日本等国饮用水标准。
总之一句话,我国自来水标准也并不比发达国家低。这又不得不回到开头的疑问,为什么他们敢喝,我们不敢喝?
文化和习惯差异
先不说自来水干不干净,仅从生活习惯来看,咱们国人一直以来更喜欢喝热水,尤其是几千年的饮茶文化,让开水深深烙印在每个国人的心底。并且喝冷水闹肚子,这是中国很常见的体质。因此,即使自来水干净无害,我们也不会经常饮用。而欧美人除了咖啡是热的之外,更偏爱冷水甚至是冰水。去国外餐厅吃饭,服务生肯定会给你端来一杯冷冰冰的自来水,他们叫做“tap water”。如果你给外国人一杯热水,他反而会觉得很奇怪,难以接受。
