亥姆霍兹极地海洋研究中心的科学家们宣布了一项惊人的发现,北极海洋中的已经发现大量塑料微粒,而且已经达到了一个创纪录水平!
经过分析后大家发现,每升海冰中发现了超过12000个塑料粒子,比此前科学家们预计的水平高出三倍。在海冰样本中,科学家们找到了大量的微小的碎片包装、油漆、尼龙、聚酯和醋酸纤维素,这些是人类日常生活中最常见的几类物质。
科学家们对北极海冰中如此高水平的塑料污染表示担忧,他们警称,这种级别的塑料污染对海洋生物和人类健康的影响仍然是未知的。
一些研究显示,微小的塑料微粒可以在海洋生物的消化道内停留,这意味着它们有被人类吃下去的可能性。此外,还有研究显示有的塑料微粒含有毒化学物质,当它们进入动物的内脏,就会将毒素释放。总而言之,如果它们能够毒害海洋生物,那么最终也将会危及人类。
