Abstract: Aim Phytoplankton monitoring as bioindicators to assess the health of the Nasarawa reservoir and also to evaluate the relationship between phytoplankton and reservoir environmental variables. Methods Phytoplankton and water samples from Nasarawa reservoir (Nigeria) were collected and analysed for ten months (February, 2018 to November, 2018) using standard methods at five sampling sites. Results A total of 38 genera belonging to five major families such as: Bacillariophyceae (42%), Chlorophyceae (24%) Cyanophyceae (13%), Deemidiaceae (18%) and Euglenophyceae (3%) were recorded. Four Phytoplankton classes; Bacillariophyta, Chlorophyta Cyanophyta, and Desmidiaceae show positive close relation with dissolved oxygen, pH, transparency, and total dissolved solids. The overall phytoplankton density in the reservoir was higher in dry season than the wet season. Palmer pollution index was employed to study the water quality of the reservoir. The total score was calculated to be 25, showing evidence of high organic pollution. Conclusions The presence of organic pollution indicators Closterium sp, Navicula sp, Nitzschia sp, Synedra sp, Chlamydomonas sp, Cyclotella sp and Anacystis sp is a warning sign of the deteriorating condition of the water quality in the reservoir. Measures need to be enforced to reduce the rate of pollution of the reservoir arising from the human activities in the catchment of the reservoir.

Based on the water quality investigation data in December of 2010, the water environment quality of Jilongshan sea area in Zhanjiang in winter was assessed using single water quality parameter model, integrated water quality index model, organic pollution index model and eutrophication assessment model. The results show that the key pollutants are dissolved inorganic nitrogen (DIN) and chemical oxygen demand (CODmn), with their average concentrations of 1.39 and 3.74mg/L, respectively. And the averages of their single parameter pollution index are 3.48 and 0.93. Jilongshan sea area is seriously polluted by DIN. None of the sampling stations are able to meet the third-rate seawater standard in the sea area. From the evaluation results, the N/P ratio is higher than Redfield ratio. DIN is the most important contribution factor to the eutrophication. The averages of single parameter pollution index, integrated water quality index, organic pollution index and eutrophication index are 1.09, 2.58, 3.78 and 22.5, respectively. Most parts of Jilongshan sea area are polluted moderately. According to the evaluation mode of organic pollution and eutrophication index, the organic pollution degree reaches the forth level and the eutrophication degree in Jilongshan sea area is very serious.

Envirometrics and pollution indices are proxies to assess water quality of a wetland ecosystem. Hence, the present study is focused on establishing water quality and elucidating the pollution status of Karamana River (KR) in Kerala, SW coast of India. The Karamana River Basin – KRB (n=6th; L= 68 km, A=695 km2), is the main source of water for domestic and drinking purpose in Thiruvananthapuram city. The Killi River (n= 5th; L= 24 km, A= 102 km2), the largest tributary of KR, carry heavy load of pollutants mainly from city and joins KR towards its downstream side. For this study, about 12 sampling stations were selected along the KR from upstream to downstream (interval= ~3km), and water samples (n=12x2= 24) were collected during non-monsoon (NON) and monsoon (MON) of 2015 to assess the variability and sourcing of key hydrochemical variables. Environmetric methods, viz., Pearson Correlation and Principal Component Analysis (PCA) were applied for apportionment of pollution sources significantly responsible for the surface water quality. It was found that sewage effluents and seawater intrusion were the primary factors deteriorating water quality in downstream. Further, the results of water quality analyses and Pollution Indices, viz., Organic Pollution Index (OPI), Eutrophication Index (EI) and Comprehensive Pollution Index (CPI) indicate that lower reaches (L= ~4 km) of KR is seriously polluted. A distinct Zone of Pollution Influence (ZPI) has been delineated based on the indices and this attempt is first of its kind in KR. The present study provides several noteworthy contributions to the existing knowledge on the factors influencing surface water quality and serves as a baseline data for watershed managers and administrators.

Biological monitoring is a valuable method used in conservation studies to protect and preserve the biological integrity of natural ecosystems. This study was conducted to assess the water quality of the Pagbanganan River using planktonic algae as bioindicators of organic pollution. Horizontal tows were made in three selected stations (upstream, midstream & downstream) using a Wisconsin plankton net with 80pm mesh size. Collected samples were preserved with Lugol’s solution and 70% ethyl alcohol. Identified phytoplankton genera were analyzed using Palmer’s Pollution Index. Out of the 20 pollution indicator genera identified by Palmer (1969), 10 were present in Pagbanganan River, namely; Ankistrodesmus, Closterium, Cyclotella, Gomphonema, Melosira, Navicula, Nitzschia, Oscillatoria, Stigeoclonium and Synedra. Four of these were among the most abundant algae in the river. Mean Palmer’s Pollution Index Scores indicate that there is “less” organic pollution existing in the river. Results imply that the river is still relatively safe for general household use, but effective conservation measures should be done to preserve the integrity of the river ecosystem.

Abstract This work has focused on a pharmaceutical plant waters and the environmental impact of its discharges. The Water Quality Index (WQI), the Organic Pollution Index (OPI) and the Sodium Adsorption Ratio (SAR) of incoming and outgoing waters were analyzed over seasonal variations for 5 months using classical and mathematical indices. Highly significant increases were observed at the output (p < 0.001) for electrical conductivity, alkalinity, calcium and sodium; very significant (p < 0.01) for nitrites, COD and BOD5; significant (p < 0.05) for turbidity, potassium and chlorides. The sulfates, nitrates, phosphates, ammonia, TSS, magnesium, aluminum, iron and manganese showed no significant differences (p > 0.05). These parameters remained high all over the study period except for the BOD5. The WQI was reported in input waters in the range 85.9–89.5 indicating water safe for domestic use, range 42.3–60.9 (medium to bad) in output waters highlighting the water pollution. The OPI highlighted waters with low-to-moderate pollution, essentially due to high levels of nitrites. The SAR was found in “medium-to-high” salinity and “low sodium” ranges, thus precautions required in soils but without significant global effects. The COD/BOD5 ratio highlighted a wastewater sometimes difficultly biodegradable (ratio > 3). In conclusion, often throughout all the study period, the outgoing waters were found with bad quality and non-negligible risks for soils; it is thus strongly advocated that these waters must undergo appropriate treatment to improve its physicochemical quality.

The sublittoral macrobenthic invertebrate populations of the Upper Clyde Estuary are described. The estuary has a long history of organic pollution. The long term changes in species composition, faunal density and dominance patterns between 1974 and 1980 are presented. The fauna is dominated by brackish, pollution tolerant oligochaetes and polychaetes. Fluctuations in populations can be related to both seasonal variation in environmental conditions and long term improvements in water quality through a reduction in pollution loading to the estuary.

The Impact

In order to maintain the environmental carrying capacity of coastal tourism, this research was conducted to determine the condition of river water environmental pollution in the Petitenget beach area and pollutant source activities. Determination of water quality is carried out by analyzing the water quality taken at several sampling points in the four rivers that lead to the Petitenget beach. Determined the pollution index value (IP) of the physical chemical and biological pollution parameters. The results showed that the four rivers that flow into the Petitenget Beach area had been contaminated with indications of pH, BOD, COD, ammonia, Coliform and E. coli which exceeded water quality category III class quality (PerGub Bali No 16 Year 2016). The four rivers are included in the criteria of severe contamination. The four rivers have experienced physical damage or structural changes that have very high discharge fluctuations both in quantity and quality. Slimy basic structure, smelly and slum aesthetic waters. While the indication of the impact of pollution is waste water which is directly discharged into the river from hotels, restaurants, homestays, commercial centers and settlements.
