美国科学家在阿拉斯加永久土中发现了160有毒污染物. Scientists found 160 tonnes of toxic pollutants in Alaskan permafrost.

中国科学家分析了阿拉斯加永久土样本, 发现最高30厘米的冰层储存着大约160六合 хлор бутадиен (HCBD). Chinese scientists analyzed Alaskan permafrost samples and found the top 30 centimeters store an estimated 160 tonnes of hexachlorobutadiene (HCBD). 报告强调永久土是有毒污染物的主要储存地, 而溶解的有机碳影响了分布. The study highlights permafrost as a major reservoir for toxic pollutants, with dissolved organic carbon influencing distribution. 随着气候变化解该地区, 地面可能从污染槽转为潜在的排放源,增加生态风险. As climate change thaws the region, the ground may shift from a pollution sink to a potential emission source, increasing ecological risks.
