Abstract

The rise in human population densities and the pace of development had intensified the depletion of the water quality. This study aimed to analyze the concentration of dissolved oxygen (DO), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) during wet season and dry season at Terengganu River in 2016. A total of 29 monitoring stations in the study area were selected and three water quality parameters were analyzed using descriptive statistics and the correlation matrix methods. The DO ranged from 2.11 to 8.07 mg L-1, COD from 2.24 to 39 mg L-1 and BOD from 0.67 to 6.52 mg L-1 for the wet season while in dry season, DO ranged from 2.30 to 6.05 mg L-1, COD from 1.9 to 20.48 mg L-1 and BOD from 0.04 to 13.99 mg L-1. Spearman’s correlation test shows there was a weak correlation between DO and COD during wet season, while in the dry season, there was a weak correlation between DO-COD and DO-BOD. This study also found out that urbanization and anthropogenic activities in the area can gave the more impact towards seasons and water quality deterioration in Terengganu River, Malaysia.

马来西亚登嘉奴河流域溶解氧、生化需氧量和化学需氧量的季节变化

人口密度的增加和发展速度的加快加剧了水质的枯竭。本研究旨在分析2016年登嘉楼河干湿季节溶解氧(DO)、生化需氧量(BOD)和化学需氧量(COD)浓度。选取研究区29个监测站，采用描述性统计和相关矩阵法对3个水质参数进行分析。丰水期DO为2.11 ~ 8.07 mg L-1, COD为2.24 ~ 39 mg L-1, BOD为0.67 ~ 6.52 mg L-1，枯水期DO为2.30 ~ 6.05 mg L-1, COD为1.9 ~ 20.48 mg L-1, BOD为0.04 ~ 13.99 mg L-1。Spearman相关检验表明，DO与COD在丰水期呈弱相关，DO-COD与DO- bod在枯水期呈弱相关。本研究还发现，该地区的城市化和人为活动对马来西亚丁加奴河的季节和水质恶化的影响更大。

期刊介绍： The Journal of Environmental Science and Management (JESAM) is an international scientific journal produced semi-annually by the University of the Philippines Los Baños (UPLB). JESAM gives particular premium to manuscript submissions that employ integrated methods resulting to analyses that provide new insights in environmental science, particularly in the areas of: environmental planning and management; protected areas development, planning, and management; community-based resources management; environmental chemistry and toxicology; environmental restoration; social theory and environment; and environmental security and management.
