“…Kelly and Whitton (1995) suggested the diatom index (Diatomeae) was an excellent indicator for eutrophic monitoring in river. Phytoplankton morphological classification was considered as a good tool to reflect the water quality from Nile River (Saad and El-Karim 2015).…”

In this study we investigated the variation of phytoplankton and the water quality in Vam Co River, Southern Vietnam. Phytoplankton were bi-monthly monitored in 2011 at 12 sampling sites in the river. Some basic environmental parameters were also monitored including temperature, pH, turbidity, inorganic nitrogen and dissolved phosphorus. The phytoplankton biodiversity and Diatomeae indices were applied for environmental quality evaluation. The results showed that temperature ranged from 28.7 – 31.9 °C during the monitoring. The pH and turbidity were in between 3.9 – 7.0 and 2 – 64 NTU, respectively. The nitrate and ammonium concentrations were from 0.06 – 1.21 and 0.03 – 1.15 mg/L, respectively. The phosphate concentration was between 0.02 and 0.37 mg/L. The environmental parameters were favorable for phytoplankton development. The phytoplankton analyses showed that there were 290 species of diatoms, green algae, golden algae, yellow algae, euglenoids, dinoflagellates and cyanobacteria of which green algae and diatoms were dominant in species number. Phytoplankton density ranged from 920 – 383 600 individuals/L with the main dominant species of diatoms. The biodiversity index values during the monitoring were from 0.15 – 3.80 characterized for oligotrophic to eutrophic conditions whereas the Diatomeae index values were more than 0.2 indicating for the eutrophic characteristic of the aquatic environment. Besides, phytoplankton species number positively correlated with temperature but negatively correlated with nitrate concentration. Additionally, the biodiversity positively correlated with temperature and species number, but negatively correlated with nitrate and phytoplankton abundance. The results confirmed the advantage of using phytoplankton and their indices for environmental monitoring and water quality assessment.

“…Dünya nüfusunun hızlı artışı sonucu artan su ihtiyacı ve su kalitesinin bozulması nedeniyle dünya çapında tatlı su ekosistemlerinin ekolojik durumlarının tayini önemli derecede artmıştır (Çelekli ve Lekesiz, 2021). Son on yılda birçok ülkede su kalitesini belirlemek için sadece fiziksel ve kimyasal parametreler değil, aynı zamanda biyolojik veriler de kullanılmaktadır (Abd El-Karim, 2015;Toudjani ve ark., 2018) Ülkemizde alglerin gösterge olarak kullanıldığı biyolojik izleme çalışmaları hızla artmaktadır (Atıcı ve Ahıska, 2005;Varol ve Şen, 2014;Tezel Ersanlı ve Öztürk, 2017;Morkoyunlu Yüce ve ark., 2018).

Akarsu ve durgun suların su kalitesinin belirlemesinde algler büyük önem arz ederler. Kille Çayı’nın planktonik alglerinin ekolojisini incelemek amacıyla Nisan ve Ekim 2019 tarihlerinde 2 istasyonda örnekleme gerçekleştirilmiştir. Yapılan bu araştırmada, Bacillariophytadan 32, Chlrophytadan 16 ve Cyanobacteriadan 6 olmak üzere toplamda 54 fitoplankton türü tespit edilmiştir. Su sıcaklığı (T) 13 ile 25°C, çözünmüş oksijen (ÇÖ) 3.55 ile 7.85 mgl-1, elektriksel iletkenlik (Eİ) 1346 ile 1631 μScm-1, pH 6.75 ile 7.84, nitrat azotu (NO3) 0.43 ile 0.86 mgl-1, toplam azot (TN) 1.9 ile 5.85 mgl-1, fosfat (PO4) 0.06 ile 0.08 mgl-1 ve toplam fosfor (TP) 0.06 ile 0.15 mgl-1 aralıklarında ölçülmüşlerdir. Bacillariophytadan Fragilaria capucina, Cymbella silesiaca, Gomphonema parvulum, Navicula subrhyncocephala, Navicula veneta, Chlorophytadan Cosmarium vexatum, Dictyosphaerium pulchellum, Tetrastrum komarekii, Cyanobacteriadan Aphanothece clathrata ve Chroococcus turgidus baskın türler olarak belirlenmiştir. Tespit edilen baskın fitoplankton türlerine göre Kille Çayı ötrofik karakterli bir su kütlesidir.

Analysis of water such as river and lakes can provide an insight into their composition and potential impact on the environment. Nsit Ubium River is a fresh water body that flows through urban areas in Akwa Ibom state. The locals attached a lot of socio-economic importance to the river, as a result of this a lot of humans generated pollutants find their way into it. Researching on the autecology of microalgae in the river, water and algae sample were collected from the river for the period of four months (October 2021 to January 2022) and analyzed for physiochemical parameters and species diversity using standard procedures. Water samples were collected using 1 litre transparent bottle while microalgae samples were collected by scrapping the attached plants on the river bank into a transparent bottle and preserved with a drop of a mixture of formaldehyde and lugol iodine. pH ranged between (4.1 and 5.8), conductivity between (15 and 153), alkalinity between (5.0 and 5.8), Nitrate between (0.5 and 0.80Mg/L), phosphate between (5.01 and 7.8Mg/L) and dissolve oxygen between (6.27 and 9.22mg/l) were determined. Five divisions of algae comprising of 92 taxa were identified during this study. The division, Bacillariophyta was the most represented division accounting for 80% occurrence and a total of 72 species, this was followed by Chlorophyta with 10%, Euglenophyta (7%), Cyanophyta (2%) which were accounted for 9, 6 and 2 taxa respectively. Dinophyta was the least represented with (1%) and contributed only one taxon. The month of November has the highest number of species with total of 54 taxa while December has the least occurrence (31 taxa). The composition of microalgae in Nsit Ubium River were dominated by diatoms (Bacillariophyta) which are good pollution bio-indicators. The Cyanophyta indicates higher nutrient enrichment which could have been due to runoff from agricultural land or waste water discharge. Therefore, the documented algae in the river could be usedful as a pollutant indicator in assessing pollution status of rivers.
