Review on heavy metal pollution in major lakes of India: Remediation through plants

The historical lakes of India are getting over burdened with the loads of pollution due to the rapid growth of small scale industries, nutrient enrichment and other anthropogenic activities. The high concentrations of metals in the water bodies, their entry into ecological food chain and the resulting health effects are of great concern to the researchers in the areas of ecology. Due to the problems associated with the...

Deforestation in power line construction in the Central African Region

Power transmission lines in forest regions like the southern parts of Cameroon are subjected to numerous failures arising from natural hazards, including earth faults and line ruptures provoked by swaying or falling neighbouring trees and their branches. To pre-empt this problem, those trees which represent a potential threat to the operation of the power line must be eliminated. Deforestation during line construction...

Bioremediation of soil and water polluted by cyanide: A review

Cyanide is a chemical that is widely distributed in the environment, mainly as a result of anthropogenic activities. Only small quantities are naturally produced. Most industrial activities use this chemical compound for manufacturing a product as electroplating or for extracting gold. Exposure to cyanide results in negative health impacts to the wildlife and humans. In nature, cyanide occurs in several species and...

Seasonal macrophyte diversity and water quality in an urban wetland

The ecosystem services of encroached urban wetlands that receive wastewater and surface run-offs have become more challenging due to climate variability. Our study assessed the seasonal macrophyte diversity and water quality of the streams flowing into and out from Pece wetland in Gulu Municipality. The macrophyte species in the wetland were sampled along five transects. Water samples from the streams were also...

Using Citizen Science Approach to monitor water, sanitation and hygiene Related Risks in Karonga Town, Malawi

Relatively few studies have explored how resilience of water, sanitation and hygiene (WASH) systems to hazards can be enhanced under the current and future development and climatic challenges pressures in urban areas. This study employed the citizen science approach to build the capacity of citizens and integrate communities into scientific research on water quality and WASH related risk monitoring. Data was collected...

Geoelectrical logging for well screening in prolific aquifers in Ubima, Ikwerre Local Government Area, River State, Nigeria

Geoelectrical logging was conducted in two well locations in Ubima community, Niger Delta, Nigeria. Self-Potential (SP) and Resistivity (Short Normal and Long Normal) logs were employed. Two points each in wells 1 and 2, respectively, were tested to determine the porosity (ɸ), permeability, k and the total dissolved solids (TDS) in the aquifer by derivation from electrical conductivity (EC). The results show that for...

Impacts of bacterial pollution on hand-dug well water quality in Enugu, Enugu State, Nigeria

This study investigated the effect of bacterial pollution on ground water quality in Enugu urban areas. During the study, samples were collected from ten (10) hand-dug wells (W1-W10c). Five (5) hand dug wells out of ten (10) were used as control. All samples were taken according to methods described by Federal Ministry of Water Resources (2004). Membrane filtration (MF) method was used to enumerate total coliforms (TC),...

Kinetic analysis of anaerobic sequencing batch reactor for the treatment of tannery wastewater

A pilot scale anaerobic sequencing batch reactor (ASBR) was operated at different organic loading rate (1.03, 1.23, 1.52 and 2.21 kg.m-3.d-1) in order to determine the chemical oxygen demand (COD) removal and methane production kinetic models. The system was operated at mesophilic temperature. The wastewater was fed using submersible pump in every twenty four hours and agitated with hydraulic pump for fifteen minutes in...
