全球83%饮用水遭污染!科学家:水中含有塑料纤维

2017-09-06 17:21:49   中国青年网

据台湾“联合新闻网”9月6报道,科学家为非营利媒体“Orb Media”检测了全球10多个国家的饮用水,结果发现,83%的样本中发现塑料纤维,显示全球数十亿人的饮用水遭塑料分子污染。

研究人员在2017年的1-3月期间,取得美国、英国、印度等国的饮用水,并加以分析。结果表明,美国塑料污染率最高,高达94%,样本取自美国国会大厦、美国国家环境保护署总部和纽约特朗普大厦。黎巴嫩和印度污染率则次之。英国、德国、法国等欧洲国家污染率最低,但仍达72%。

美国纽约州立大学弗雷多尼尔分校微型塑料专家雪莉?梅森表示:“如果塑料影响野生动物,那么我们怎么会觉得塑料不会影响人类呢?” 爱尔兰高威梅努斯理工学院安妮玛丽?马宏表示,目前还不清楚塑料会对健康有何影响,但有两大顾虑,分别是小型塑料分子,以及窝藏在微型塑料上的化学分子与病源体,“奈米级的纤维可能穿透细胞,代表也可能穿透器官,这令人担忧。”微型塑料会携带和吸收化学物质,野生动物进行的研究显示,动物体内含有微型塑料。

报道称,微型塑料如何进入饮用水仍是个谜团,不过大气显然是一大原因。塑料纤维可能随着大气循环流入水系统中,雨水中携带塑料分子,并一路流入湖泊,也许这可以解释印度尼西亚家用井水以及黎巴嫩的天然泉水中何以出现微型塑料。目前标准的净水系统无法过滤所有的微型塑料分子。
