英文摘要The basic water quality data and concentration data of As and Sb in the sluice controlled river section of Xiaoqing river in three different water conditions in 2015 were obtained. The spatial and temporal distribution characteristics of As and Sb in the river section were analyzed, and we estimated their land-toocean fluxes. The results show that the spatial distribution of pH, salinity and temperature in the sluice controlled river section of the Xiaoqing river is closely related to the water situation. The topography of the Xiaoqing river estuary is also an important factor affecting the exchange of water from the upper reaches to the lower reaches. The concentration of As and Sb in water bodies decreased gradually along the reach from Wangdao sluice to the estuary in dry period and flat period, while the concentration of As and Sb in wet period was significantly lower than that in dry and flat periods. The release of As in sediment increased the concentration of As in the pore water, with a maximum value of 24.9 mug/L. In 2015, the land-to-ocean fluxes of As and Sb were about 2618 and 2677 kg, respectively.
中文摘要获取了2015年3个不同水情时期小清河闸控感潮河段水体的基本水质指标数据以及As和Sb的浓度数据,分析了该河段As和Sb的时空分布特征,并对其入海通量进行了估算。结果表明,小清河闸控感潮河段pH、盐度和温度的空间分布与小清河水情密切相关,小清河口地形地貌也是影响上游河水与下游海水交换的一个重要因素。枯水期和平水期水体中As和Sb的浓度沿王道闸到河口明显呈现逐渐降低的趋势,丰水期As和Sb的浓度值明显小于枯水期和平水期。沉积物中As的释放增大了孔隙水中As的浓度,最高达到24.9 mug/L。2015年小清河As的入海通量约为2618 kg,Sb的入海通量约为2677 kg。
