一项研究显示,加拿大的虎鲸面临很高的毒素水平,危及它们的健康和生殖。 A study reveals Canadian killer whales face high toxin levels, risking their health and reproduction.

麦克吉尔大学的一项研究发现,加拿大东海岸沿岸的虎鲸受到包括多氯联苯和农药在内的高浓度的持久性有机污染物的危害,大大增加了它们发生免疫和生殖问题的风险。 A McGill University study found that killer whales off Canada's East Coast are exposed to dangerously high levels of persistent organic pollutants, including PCBs and pesticides, significantly increasing their risk of immune and reproductive issues. 经分析的皮肤样本表明,虎鲸体内的毒素水平是与生殖衰竭有关的临界值的两倍。 Analyzed skin samples indicated toxin levels in killer whales are double the threshold linked to reproductive failure. 研究强调需要制定更强有力的规章,以减少水污染,保护这些脆弱的海洋哺乳动物。 The research underscores the need for stronger regulations to reduce water pollution and protect these vulnerable marine mammals.
