This paper aimed to describe the effects of sand mining on the Kelantan River with respect to physical and chemical parameter analyses. Three replicates of water samples were collected from five stations along the Kelantan River (November 2010 until February 2011). The physical parameters included water temperature, water conductivity, dissolved oxygen (DO), pH, total dissolved solids (TDS), total suspended solids (TSS) and turbidity, whereas the chemical parameters included the concentration of nitrogen nutrients such as ammonia, nitrate and nitrite. The Kelantan River case study revealed that TSS, turbidity and nitrate contents exceed the Malaysian Interim National Water Quality Standard (INWQS) range and are significantly different between Station 1 (KK) and Station 3 (TM). Station 1 has the largest variation of TDS, TSS, turbidity and nitrogen nutrients because of sand mining and upstream logging activities. The extremely high content of TSS and the turbidity have caused poor and stressful conditions for the aquatic life in the Kelantan River.
本文旨在通过物理和化学参数分析描述采砂对吉兰丹河的影响。于2010年11月至2011年2月期间，从吉兰丹河沿岸的五个站点采集了三份水样复制品。物理参数包括水温、水电导率、溶解氧（DO）、pH值、总溶解固体（TDS）、总悬浮固体（TSS）和浊度，而化学参数包括氮营养素如氨、硝酸盐和亚硝酸盐的浓度。吉兰丹河案例研究表明，总悬浮固体、浊度和硝酸盐含量超过了马来西亚国家临时水质标准（INWQS）范围，并且在1号站点（KK）和3号站点（TM）之间存在显著差异。由于采砂和上游伐木活动，1号站点的总溶解固体、总悬浮固体、浊度和氮营养素变化最大。总悬浮固体和浊度的极高含量对吉兰丹河中的水生生物造成了恶劣和压力大的生存条件。
