“…Nitrogen and phosphorus (P) are essential nutrients for aquatic organisms for primary production in lake ecosystems. The excessive of nitrogen (N) and phosphorus (P) is a key factor for eutrophication (Wan et al, 2020). Lake sediment plays an important role in water quality by acting as a nutrient source and sink (Lee et al, 2019).…”

The occurrence of cyanobacterial blooms (CYBs) associated with cyanotoxins has been reported worldwide. While planktonic cyanobacteria and the contamination of microcystin (MC) in the water column have been the subject of many investigations, little attention is paid to the benthic cyanobacterial communities and MC concentration in the benthic environment. This study aimed to investigate the benthic cyanobacterial composition and MC concentration accumulated in sediment from the Tri An Reservoir (TAR), Dong Nai province. Benthic cyanobacterial communities and sediment were collected at five sites in dry and rainy seasons. The benthic cyanobacterial communities were morphological observation and identification. Different nitrogen, phosphorus species, and chlorophyll-a (Chl-a) in sediment were analyzed. MCs concentration in sediment was quantified by High-Performance Liquid Chromatography (HPLC). Results indicated that the sediment from the TAR was contaminated with nitrogen. A total of 19 species belonging to 12 genera, 3 orders of cyanobacteria were identified. In which, Anabaena, Oscillatoria, and Microcystis were the three most commonly found in the samples. Surface sediment samples contained high densities of colonial Microcystis. The Chl-a concentration in sediment in dry and rainy seasons ranged from 1.96–3.45 and 0.71–3.15 µg/g fresh weight (FW), respectively. MC was detected in sediment at all sites in both dry and rainy seasons with a concentration up to 191.4±14.2 ng/g FW. The outcome of this study provides basic knowledge on MC and potential MC-producing cyanobacteria in a drinking water supply. Further investigation on the toxic producing ability of the benthic cyanobacteria species from the Tri An Reservoir is required.

Studies on phosphate levels (total, polyphosphate, and orthophosphate) have been carried out in the Lamat Muntilan watershed. A detergent is an approach to the amount of waste disposal of various types of phosphate in the Lamat river. High levels of phosphorus cause eutrophication, which can cause various human health problems. This study aims to determine the levels (total, polyphosphate, and orthophosphate) and compared rain and dry season with water quality standards that have been agreed upon nationally as well as theoretical studies on eutrophication pollution. This research uses the UV-Vis Spectrophotometer method by utilizing the interaction of ammonium tartrate and potassium antimonyl tartrate on orthophosphate ions to form phosphomolybdic acid which is then reduced by ascorbic acid to a modern blue color which is proportional to the number of orthophosphate ions. This modern blue color is measured at a wavelength of 880 nm. The result data showed that the average total phosphate levels of river water of 0.240 ppm in the rainy season and 0.204 ppm in the dry season, for polyphosphates were found at 0.032 ppm in the rainy season and 0.064 ppm in the dry season, while orthophosphate 0.051 ppm in the rainy season and 0.101 ppm in the dry season. In the dry and rainy seasons, there were specific differences between them. This level surpassed Peraturan Pemerintah Republik Indonesia Nomor 82 Tahun 2001 about concerning Management of Water Quality and Control of Pollution Water, was not suitable for consumption directly or indirectly specifically for human needs, but if it was used for animals and plants it is still feasible. The level of all phosphate species triggered the formation of eutrophication.

“…In XW Reservoir, the content of four metal elements gradually decreased from the main stream to the dam front and then increased to the tributary, while in NZD Reservoir, the content of metal elements in the transition region were higher than that of the dam front and the main stream. The change of metal elements in sediment of the two reservoirs might be related to different sedimentary environments and land use patterns (Wan et al 2020).…”

The influence of cascade reservoirs construction on labile phosphorus (P) is an important scientific problem in the Lancang River. The concentration of labile P in cascade deep-water reservoirs were determined, and the influence of cascade reservoirs construction on the DGT-labile P was analyzed. The construction of cascade reservoirs led to significant differences in concentrations of DGT-labile P, which in the upstream of Xiaowan (XW) Reservoir were differences from that in the downstream Nuozhadu (NZD) Reservoir. The P diffusion fluxes in XW Reservoir were − 8.59–250.50 ng·cm− 2·d− 1, and that in NZD Reservoir were 3.82–24.80 ng·cm− 2·d− 1. The P pollution of XW Reservoir was higher, highlighting the importance of controlling P pollution of XW Reservoir. The construction of cascade reservoirs had made the release of DGT-labile P more dependent on the reductive dissolution of Mn oxides. The early diagenesis transformed bio-availability P (BAP) remobilization into DGT-labile P that made the increase of DGT-labile P/BAP with depth. However, the DGT-labile P/BAP of upstream XW Reservoir was 7.8 times larger than that of downstream NZD Reservoir, which indicated that the construction of cascade reservoirs weakened the remobilization of P in sediment.
