2013年1月至2014年3月,在长江中游江汉平原的39口威尔斯监测井中,每月采集1年零3个月的地下水样品,研究了地下水中As等组分的时间变异性。地下水中的K,Na,Ca,Mg的浓度一般变化小于30%,而氧化还原敏感组分(Fe,NH 4-N,S和As)的浓度随时间变化较大。在25 m以下承压含水层的威尔斯井中,地下水As浓度较高,季节性变化范围达760 ±320 μg/L。较高的As浓度与增加的百分比As(III)在雨季和减少对旱季结束,表明减少动员响应地下水位波动。
Samples were collected every month from 39 monitoring wells over a period of 1 year and three months (from Jan 2013 to Mar 2014) in the Jianghan alluvial plain in the middle reaches of the Yangtze river, central China, to evaluate the temporal variability of groundwater composition for As and other constituents. The concentrations of K,Na,Ca,Mg in groundwater generally varied less than 30%, whereas concentrations of the redox-sensitive components (Fe,NH4-N,S and As) varied greater over time. In wells tapping the confined aquifers with depth of 25m, concentrations of groundwater As were much higher and ranged up to760 ±320 μg/L seasonally. Higher As concentration were associated with an increasing percentage of As(III) in rainy season and a decrease towards the end of dry season, indicating a reductive mobilization responding to groundwater level fluctuation.
