【Abstract】 for many years Jianjiang River and its branches have suffered from the pollution of pit 16 wastewater of coal mines,with the total iron(Fe) as the dominating pollutant.By comparing the total iron concentrations for the same seasons of 2001and 2012,we found that the overall pollution of Jianjiang River and its branches became heavier,suggesting that suitable measures,such as natural aeration and precipitation,should be taken to mitigate such pollution.更多还原
