Sources and Health Effects of Arsenic, Fluoride, and Nitrate in Water
Abstract: Arsenic, fluoride, and nitrate are major inorganic contaminants in water that pose significant risks to human health. These contaminants are introduced into water sources through both natural geological processes and human activities. Arsenic is primarily released from arsenic-bearing minerals through weathering, dissolution, and erosion, while human activities such as agriculture, mining, and fossil fuel combustion further enhance its presence in water. Fluoride contamination mainly results from the dissolution of fluoride-bearing …

Physicochemical Analysis of Groundwater Quality In Owerri Municipal, Imo State, Nigeria Using MATLAB and ANN Models.
Abstract: The physicochemical analysis of groundwater quality in Owerri Municipal council, Imo state, Nigeria was carried out. Fifteen water samples were randomly selected from the five villages that make up Owerri municipal council were anlayzed for physicochemical parameters using standard methods. The results from the study area showed that the temperature ranged between 26.5-28.0oC; рH ranged between 4.80-5.32. Electrical conductivity ranged between 77-166 µЅ/cm. The total dissolved solids were between 35.4-168.4mg/l; …

Assessment of Water Quality Deterioration in Sacred Ponds of Varanasi: Impact of Urbanization, and Pollution
Abstract: Water scarcity, pollution, political unrest, and population growth have made it imperative to manage water resources, including surface water, responsibly in the twenty-first century. The ponds deteriorate due to development, urbanization, and the burden of many polluting sources. Varanasi had roughly 110 pounds and kunds in the 1980s; today, there are only 56. The physical and chemical quality parameters of five significant sacred ponds that have existed in Varanasi from …

Phytoremediation of Aquaculture Wastewater: Duckweed (Lemna minor L.) as a Phytoremediator
Abstract: Aquaculture systems discharge huge quantities of waste into the aquatic ecosystem, in the form of excretory products and excess feed. These have grave implications on physicochemical and biological quality of the receiving environment. The study aimed to determine potential of duckweed (Lemna minor L.) for phytoremediation of aquaculture effluent. Hundred grams (100 g) of duckweed was grown in 10 L aquaculture effluent for 7-, 14-, 21-, and 28-day retention period …

Nitrate/Nitrite in The Lotic System of Yamuna and Gang
Abstract: The pollution of the Ganges River and Yamuna River has become a serious environmental challenge in India. Despite the implementation of several government initiatives aimed at river conservation, these rivers continue to receive large quantities of untreated industrial effluents, municipal sewage, and agricultural runoff. Such contamination has resulted in the degradation of aquatic ecosystems and poses significant health risks to millions of people who depend on these rivers for drinking …

Performance Evaluation of Eichhornia crassipes and Pista Stratiotes for Treatment of Aquaculture Wastewater
Abstract: The significance of wastewater management and disposal in aquaculture is growing steadily as a result of strict water regulations pertaining to the release of waste into natural water systems. The conventional methods are expensive to manage and thus, it is not sustainable especially in the developing countries. Therefore, the objective of this research is to utilize Eichhornia crassipes (Water hyacinth) and Pistia stratiotes (Water lettuce) in phytoremediation techniques as an …

Investigation of Pollution Status in River No. 2, Freetown, Sierra Leone, Using Physicochemical and Bacterial Indicators
Abstract: This study assessed the physicochemical and bacteriological quality of surface water in the River No. 2 watershed, Sierra Leone, through monthly sampling from March–August 2024 at upstream, midstream, and downstream sites. Analyses included temperature, turbidity, pH, electrical conductivity, total dissolved solids, ammonia, fluoride, sulfite, nitrate, lead, arsenic, chromium, and microbial indicators (Escherichia coli, fecal and non-fecal coliforms). Most physicochemical parameters met WHO drinking-water guidelines. pH (7.0–7.3), TDS (7–17 mg/L), turbidity …

Impact of Groundwater Pollution on Carcinogenic and Non-Carcinogenic Health Effects: A Review
Abstract: Groundwater is a critical source of drinking water in many regions worldwide, particularly in South and Southeast Asia, where dependence on untreated groundwater remains high. However, increasing groundwater contamination poses serious risks to human health. This review synthesizes recent peer-reviewed studies to examine the sources, distribution, and health impacts of major groundwater contaminants, with a focus on both carcinogenic and non-carcinogenic risks. Emphasis is placed on fluoride, nitrate, chromium, and …

Polymer Chemistry Perspectives: Applying the Water Quality Index (WQI) for Groundwater Quality Assessment
Abstract: Through the utilization of polymers' special qualities, such as their capacity to concentrate analytes and their affinity for particular pollutants, we establish a strong framework for assessing groundwater quality. A more thorough understanding of groundwater contamination is made possible by the integration of polymer-based techniques with the WQI, empowering stakeholders to decide on remediation and water resource management strategies with knowledge. The quality of groundwater, especially shallow groundwater, is being …

Water Hyacinth (Eichhornia crassipes) as Phytoremediator of Abattoir Contaminated Effluents
Abstract: The abattoir industry provided meat for more than 170 million Nigerians and job opportunities for teeming population. It has also been categorized as one of the industries responsible for major pollution of soil and water resources. The aim of this study was to analyze the pollutants present in the effluents from the selected abattoir and evaluate the effectiveness of water hyacinth (Eichhornia crassipes) in removing these pollutants. The experiment was …

The Effects of Physiochemical Parameters and Microbial Counts on Metal Coupons Corrosions in Freshwater Environment at Different Water Depths
Abstract: The effect of water quality on metal coupon corrosion was investigated at the New Calabar River in Choba. The study examined metal corrosion rates at five different depths: 30 cm, 60 cm, 90 cm, 120 cm, and 150 cm in a freshwater environment. Water samples were collected at each depth and analyzed for physicochemical and microbial parameters to understand their impact on metal degradation. Key parameters measured included pH, Electrical …
