any of these samples contained hazardous and toxic elements including cadmium, mercury and lead – in some cases in 「very high concentrations」, as outlined in a 2018 paper in the journal Frontiers of Environmental Science. A large proportion of these toxic elements are now banned or restricted. This 「reflected the age and residence time of the plastic stock in the lake,」 says Filella: the plastic waste has been building up over several decades. And as we know, plastic can take hundreds of years to degrade. 據2018年《環境科學前沿》(Frontiers of Environmental Science)的一篇論文概述，許多樣本含有有害及有du元素，包含鎘、汞和鉛——這些元素在部分樣本中的 '濃度十分高'。這些dunature元素中很大一部分現在現已被制止運用，或許約束運用。這'反映了塑料物在淡水湖中産生的時刻以及存留時刻，'菲萊利亞說：這些塑料廢物累積了數十年。眾所周知，塑料需求數百年時刻才幹降解。免費閱讀 計劃外完整版 These types of plastics are in line with what washes up on many beaches. But there was one major difference. The hazardous elements the team found 「appear to occur in higher abundance in the plastics retrieved from Lake Geneva」 than in samples from the ocean, says Filella. 正因為此，塑料對於野生生物的影響成為了人們重視的焦點。塑料許多存在於水中、海邊、湖岸以及河灘，或許會被野生動物攝入體內，而這種狀況常常髮生。假如動物將塑料吞食，其體內的胃酸或許會加快降解塑料，而這將導致塑料更快地開釋有害元素，而且對動物本身也會形成影響。因為缺少研討，人們至今沒有徹底清楚淡水生物怎樣處理攝入體內的塑料廢物。 I！（逍遙戰神江策免費閱讀、逍遙戰神江策丁夢妍免費閱讀、逍遙戰神江策最新章節、逍遙戰神江策筆趣閣）、（江策丁夢妍免費小說、江策丁夢妍閱讀全文免費、江策江陌免費閱讀、江策江陌筆趣閣）、（修羅戰神江策免費閱讀、修羅戰神江策丁夢妍、修羅戰神小說、修羅戰神txt全集下）
