摘要
水流是河流维持生态健康状态的重要条件。研究了图拉格河的低流量及其对重金属浓度的影响。一般来说，从一月到五月，这条河的流量很少。从6月到10月，结果正好相反。考虑到这个事实，我们对八种不同的重金属进行了统计分析。在枯水期，5种重金属均超过灌溉标准限值。考虑灌溉标准，枯水期污染程度顺序为:Mn > Cd > Pb > Fe > Cr > Ni > Zn > Cu。因此，保持水系的适度流量是必要的。环绕。科学。与自然资源，10(2):177-182 2017
Impacts of Low Flows on Heavy Metal concentrations in Turag River Bangladesh
Water flow is a vital requirement of a river to secure ecological health status. We investigated the low flow of Turag River and its effect on the heavy metals concentration. Generally, the water of the river flowed very less from January to May. The reverse result was found from June to October. Keeping in mind this fact, eight different heavy metals were statistically analyzed. We observed that during low flow season five heavy metals surpass the standard limit for irrigation. Considering irrigation standard, the order of contamination level was: Mn > Cd > Pb > Fe > Cr > Ni > Zn > Cu in low flow season. Therefore, it is necessary to maintain moderate flow in the river system.J. Environ. Sci. & Natural Resources, 10(2): 177-182 2017
