抄録/ポイント： 人工ナノ材料(ENMs)の環境運命とリスクの信頼できる予測は,慢性低濃度曝露シナリオのための複雑な生物学的に活性なシステムにおけるENM反応性のより良い理解を必要とする。ここでは,シミュレートされた淡水湿地メソコスムをENMsで処理し,環境パラメータにおけるそれらの反応性と季節的変化が水生系におけるENM運命にどのように影響するかを評価した。水に溶解することが知られている銅ベースのENMs(Kocide)と特定のリガンドの不在下での溶解に対して安定な金ナノ粒子(AuNP)を9か月間メソコスム水に毎週添加した。異なる環境区画における金属蓄積とスペシエーション変化を経時的に評価した。Kocideからの銅は水カラムにおける有機物と会合する可能性があり,陸生土壌に輸送され,それが有機あるいは硫化物相と関連する深い堆積物に輸送された。対照的に,Auは,表層堆積物に時間をかけて酸化し,移動した大型植物に蓄積した。動的な季節的蓄積と金属酸化還元循環が,AuNPの大型植物と表層堆積物の間に見出された。これらの結果は,環境の生物学的及び化学的複雑性が季節的変動と結合して,準安定ENMsの運命を駆動する方法の実験的定量化の必要性を示した。Copyright 2020 American Chemical Society All rights reserved.
