随着水资源危机的日益严重,地下水用于水产养殖及相应的循环水养殖模式开发将成为水产养殖领域的一个重要发展方向。然而目前中国地下水的重金属和有机物污染相当严重,利用地下水养殖可能会带来质量安全方面的风险。本文概述了地下水在水产养殖中的应用现状;详述了循环水养殖在去除重金属和有机污染物方面的优势和不足;预测已污染的地下水在用于循环水养殖后,将会产生一定的生物蓄积风险;推断地下水中主要污染物(尤其是重金属)在循环水养殖系统中的运移和归宿、系统净化单元对污染物去除的贡献以及污染物对水生态系统的影响,将是未来地下水在水产养殖中应用的重点研究内容。
With the gradual intensification of water crisis, groundwater employed in aquaculture and corresponding re- circulating aquaculture technology probably become the main concerns of aquaculture industry development in the near future. However, the current situation of groundwater contaminated by heavy metals and/or organics is rather serious in China. The present review summarizes the status of groundwater employed in aquaculture, and presents the advan- tages and disadvantages of recirculating aquaculture technology in removing heavy metals and/or organics, and espe- cially for the great advantage of recirculating technology in removing contamination from groundwater employed in aq- uaculture. It also indicates that there still exist biological accumulation risks in employing groundwater in recirculating aquaculture mode. Hence, it is conferred that the transferring and/or destination of key pollutants (especially for heavy metals) in groundwater in recirculating aquaculture mode, the contribution of systematic purifying units to pol- lutant removal, and the impact of key pollutants on ecosystem are probably the main highlights for further research on the application of groundwater in aquaculture.
