“…Slightly acidic pH of Ugandan springs were previously thought to be induced by carbon dioxide saturation in the ground water [15,20,40]. It is important to note that even within the acceptable pH range, slightly high pH causes water to have a slippery feel whereas slightly low pH may cause water to have a bitter or metallic taste [15,30,41].…”

In the current study, water from Chuho springs used as the main water source in Kisoro municipality, Uganda were assessed for their suitability as drinking water. The temperature, turbidity, conductivity, total dissolved solids, dissolved oxygen, biological oxygen demand, total hardness, total alkalinity, calcium, magnesium, phosphates, iron, copper, arsenic, chlorides and the fluoride content of the water samples were determined. Not all the parameters met World Health Organizations’ guidelines for drinking water. Temperature, dissolved oxygen and fluorides were outside the recommended limits of 15 ℃, 10-12 mg/L and 1.5 mg/L, respectively. Further studies should assess the microbiological and sanitary profile of the springs.

Aim: The use of copper-based preservatives such as chromated copper arsenate (CCA) and creosote to prolong the life of lumber present environmental concerns because they contain heavy metals and polycyclic aromatic hydrocarbons which are toxic to humans. The aim of this study was to investigate the effects of sewage sludge biosolid amendment on the distribution and mobility of chromium, copper and arsenic in chromated copper arsenate contaminated soils subjected to phytoremediation using maize (Zea mays L.). Place and Duration of the Study: Random composite soil samples from Kitetika wood factory, Wakiso, Uganda and sewage sludge biosolid from National Water and Sewerage Corporation plant in Bugolobi, Kampala, Uganda were collected and prepared. Maize grains were obtained from FICA Seeds Limited (Uganda). The pot experiments and analysis of samples were done at Mbarara University of Science and Technology (Mbarara) and Directorate of Government Analytical Laboratory, Kampala (Uganda), respectively. Methodology: The fresh CCA contaminated soils and sewage sludge biosolid were analyzed for physicochemical parameters and heavy metals (chromium, copper and arsenic). Sewage sludge biosolid was added to 1 kg of the contaminated soils at 5-25% (w/w) in 2 L plastic containers, watered and maintained at 25 ℃ for 14 days to stabilize. Controls were set up with unamended soils. Thereafter, maize was planted in the potted soils for 40 days. The concentrations of the trace metals in the soils were determined after 20 and 40 days of maize growth by atomic absorption spectroscopy. Results: The concentrations of chromium, copper and arsenic in fresh CCA contaminated soils were 365.8 ± 6.18 mg/kg, 109.72 ± 14.04 mg/kg and 28.22 ± 3.8 mg/kg, respectively. Basing on mobility factor, bioavailability of the trace metals followed the chemical sequence copper (8.9%) < chromium (17.1%) < arsenic (30.2%). Conclusion: The maize variety experimented could be used to phytoextract or phytostabilize the trace metals in the CCA contaminated soils without or with 5-25% amendment. Amendment with sewage sludge biosolid improved the phytoremediation potential of maize. Arsenic was the most mobile and bioavailable metal in CCA contaminated soils. Further studies should use other local maize varieties such as Longe series.

“…The industrial effluents, domestic wastes, urban and agriculture runoff are full of suspended solids, colored wastes, toxic substances and organic matter (Kaushik et al, 2009: Suthar et al, 2010Mishra et al, 2014;Rout, 2017;Mishra et al, 2021). The organic pollutants from industrial waste water from pulp and paper mills, textiles and leather factories, steel foundries and petrochemical refineries are the major cause of illness to aquatic flora and fauna, societies dependent on the same, where regulations do not necessarily protect the people from such industrial outflows (Chaterjee et al, 2002;Chatterjee et al, 2010;Agarwal and Saxena, 2011;Chaurasia and Tiwari, 2011;Jena et al, 2013;Angiro et al, 2020). The investigation was aimed to evaluate selected water quality attributes of the Yamuna river along the Baghpat district of Uttar Pradesh, India; which may directly or indirectly influence the biodiversity of aquatic vertebrates and parasitic infracommunities associ-ated to them.…”

Water is the main source of life. The natural aquatic resources are the major habitat for a large group ofindividuals including nonchordates to chordates. As water are the most abundantly available and occupying2/3 of the Earth and required by all kinds of life. Therefore, quality of water is of vital concern for mankindsince it is directly linked with living beings in term of habitat, sustainability, economy and human welfare.The current study is designed to work out the quality characteristics and their oscillations in physico-chemicalattributes of river Yamuna water in the district Bhaghpat, Uttar Pradesh, India. The investigation wasconducted during July, 2019 to June, 2021 and the sample was analysed in the Bioanalytical Laboratory,Department of Biotechnology, MM (DU), Mullana-Ambala (HR), India. The effects of monthly and seasonalpossible attributes including discharge of industrial effluents and natural calamities for the spatialfluctuations in the hydrobiological parameters of river Yamuna water was assessed through the advancednumerical tools. The monthly physicochemical attributes showed the seasonality biased trends during thestudy. The mean value Â± SE of water temperature (oC), dissolved oxygen (mg/l), alkalinity (mg/l), acidity(mg/l) and hardness (mg/l) was recorded as 23.7Â±1.3 oC, 4.2Â±0.22 mg/l, 100.09Â±4.8 mg/l, 44.55Â±4.38 mg/l and 550.8Â±30.3 mg/l respectively during July 2019 to June, 2020. However, the physicochemical attributesduring July 2020 to June, 2021 reflected augmented trends for water temperature (24.2Â±1.27 oC), dissolvedoxygen (5.1Â±0.16 mg/l), alkalinity (103.95Â±5.25 mg/l). On the contrary, acidity (39.92Â±2.63 mg/l) andhardness (522.48Â±39.82 mg/l) recorded decline. The observation reflected the requirement of urgent andsystematic management strategies to overcome these invisible scarce and conserve the natural quality ofthese water resources.
