Abstract

BACKGROUND AND OBJECTIVES: Dissolved organic matter has a fundamental role in supporting phytoplankton abundance and growth in aquatic environments. However, these organisms produce dissolved organic matter with varied quantities or characteristics depending on the nutrient availability and the species composition. Therefore, this study aims to assess the characteristic of dissolved organic matter on surface water and its correlation with phytoplankton abundance for monitoring water quality.METHODS: The sample was obtained at four Kali Surabaya River stations for further dissolved organic matter analysis and phytoplankton species analysis. The analysis was presented through bulk parameters of total organic, ultraviolet at 254 nm wavelength (UV254), specific ultraviolet absorbance value, and fluorescence spectroscopy using excitation-emission matrices with fluorescence regional integration analysis.FINDINGS: The results showed the bulk parameters of dissolved organic matter at all stations were significantly different, as Station 1 and 2 were higher, while 3 and 4 had a lower concentration. Furthermore, the fluorescence spectroscopy identified four components of dissolved organic matter at all stations, namely aromatic proteins-like (AP-like), humic acid-like (HA-like), soluble microbial by-products-like (SMPs-like), and fulvic acid-like (FA-like). Also, stations 1 and 2 were grouped in the high percentage FRI of humic substance (FA-like and HA-like), while 3 and 4 were classified in the high percentage FRI of non-humic substances (AP-like and SMPs-like).CONCLUSION: The main phytoplankton species, namely Plectonema sp., Pinularia sp., Nitzchia sp., Navicula sp., had the highest abundance at Stations 1, 3, and 4, respectively. A strong correlation between dissolved organic matter analysis and phytoplankton abundance led to the usage of these methods for monitoring surface water quality.
地表水水质监测中溶解有机质及其与浮游植物丰度的相关性
背景与目的:溶解有机物在支持水生环境中浮游植物的丰度和生长方面具有重要作用。然而,这些生物产生溶解的有机物,其数量或特征取决于养分有效性和物种组成。因此,本研究旨在研究地表水溶解有机质特征及其与浮游植物丰度的相关性,为水质监测提供依据。方法:在泗水河四个站点采集样品,进行溶解有机质分析和浮游植物种类分析。利用激发-发射矩阵结合荧光区域积分分析,通过总有机组分、254 nm紫外(UV254)、比紫外吸收值和荧光光谱等参数进行分析。结果:各监测站溶解有机质的体积参数存在显著差异,监测站1、2浓度较高,监测站3、4浓度较低;此外,荧光光谱鉴定了所有站点溶解有机物的四种成分,即芳香蛋白样(AP-like),腐植酸样(HA-like),可溶性微生物副产物样(SMPs-like)和黄腐酸样(FA-like)。另外,站点1和2被划分为腐殖质高百分比FRI (FA-like和HA-like),而站点3和4被划分为非腐殖质高百分比FRI (AP-like和SMPs-like)。结论:1、3、4站浮游植物丰度最高的分别是Plectonema sp.、Pinularia sp.、Nitzchia sp.和Navicula sp.。溶解有机物分析与浮游植物丰度之间的强相关性导致使用这些方法监测地表水质量。
