A Water Quality Index (WQI) is a tool that describes the overall water quality by combining complex and technical information into single meaningful unitless numerical value. WQIs predict since they reflect impact of multiple Parameters (WQPs) allow for spatial-temporal comparison status. Most African countries employ adapted modifying original index (or indices) propose their concepts evaluating surface groundwater, which normally accompanied irregularities. The current review examined...
Mercury (Hg) pollution remains an environmental global concern due to its non-degradable and toxic nature. Natural anthropogenic sources of Hg adversely affect the functioning aquatic ecosystems biological processes. In sub-Saharan Africa (SSA), unregulated artisanal small-scale gold mining (ASGM) contributes up 20% production uses 205–496 tonnes/yr Hg. Despite being a vital economic driver for 20–30 million people, ASGM threatens health systems from pollution, presenting complex challenge...
ABSTRACT Anthropogenically accelerated metal pollution of lotic systems draining mining landscapes remains a global concern due to its non‐degradability and ecotoxic nature. Nevertheless, the efficacy macrophytes as indicators remediators metal(loid) pollutants in aquatic ecosystems regions is recognised globally. However, mineral‐rich Central African Copperbelt (CACB), there limited research on effectiveness for management. Therefore, this study investigated phytopotential Typha domingensis...
A study of macroinvertebrate distribution in relation to different levels human and animal physical disturbance the sediments Njoro (highly disturbed) Ellegirini (less rivers was conducted from October 2001 June 2002, again 2012 only River. The have similar climate land-use characteristics but differ frequency intensity their sediment surfaces. Benthic macroinvertebrates were sampled during both low discharge, when disturbances high, high low. Macroinvertebrate abundance diversity higher...
The study was conducted at two sites in Sondu-Miriu basin between November 2010 and May 2011, using runoff plots to determine the temporal variation of sediments, organic matter, solids surface from agricultural land uses. At Kabianga, lower sediment values were observed natural vegetation while generally higher April-May 2011 wet season. While there significantly concentrations volumes, content 2011. Principal Components Analysis correlated erosion seasonal use activities particularly...
Invertebrate drift is one of several fundamental ecological processes in streams. However, little known about the dynamics invertebrate Kenyan In this study, we assessed two rivers, i.e. Njoro and Kamweti, that differ level anthropogenic disturbances, between February March, 2016. The aim was to evaluate effect river sampling duration (5, 10, 15, 20 25 min) period (day or night) on densities. 5-minute resulted significantly higher mean densities than other time intervals both rivers. highest...
