Consumption rates and total mercury concentration of food items and consumers collected at six sites on the Colorado River in the Grand Canyon, USA, 2007-2009

Mercury flux and fate (whether mercury was retained in the aquatic ecosystem or exported to the riparian ecosystem via blackfly emergence) was calculated based on...汞通量及其归趋（即汞是留存于水生生态系统（aquatic ecosystem），还是通过黑蝇羽化作用输出至河岸生态系统（riparian ecosystem））基于……完成了计算。
