Assessment of land-use and land-cover (LULC) change any region is one the prominent features used in environmental resource management its overall sustainable development. This study analyzed LULC changes Ngorongoro Conservation Area (NCA) surroundings using Remote Sensing Geographical Information System integrated with Cellular Automata-Markov model. The maps for years 1995, 2005, 2016 were classified unsupervised supervised classification procedure, projected 2025 2035 under...
Desorption and adsorbent regeneration are imperative factors that required to be taken into account when designing the adsorption system. From environmental, economic, practical points of view, is necessary for evaluating efficiency sustainability synthesized adsorbents. However, no study has investigated optimization arsenic species desorption from spent adsorbents their ability reuse as well safe disposal. This aims investigate ions adsorbed on hybrid granular activated carbon independent...
Abstract Textile wastewater from wet processing units is a major environmental problem. Most chemicals, including dyes, are only partly consumed, resulting in highly colored containing variety of chemicals released into the environment. This paper gives information on current management textile Tanzania. A semiquantitative analysis was done to identify main types used units, characteristics and existing treatment methods industry. The performance evaluation plants also discussed. advantages...
Abstract This study investigated the levels of Pb, Hg, Cr, Cd, and As in water sediments from tributaries Mara River, Tanzania. Pollution risk was using seven indices five metals. During dry period, highest concentration 17.45 ± 1.22, 0.01, 1.56 0.5, 1.3 0.09, 30.81 0.02 mg/kg, respectively. wet 4.37 0.28, 0.012, 2.58 0.57, 2.25 0.35, 53 For surface water, respective concentrations were 0.76 0.04, 0.68 0.74 0.1, 0.47 0.06 mg/L for period. The period max 0.56, 0.03, 0.55 0.48 0.4 0.03 mg/L,...
Treatment of textile wastewater with domestic as co-substrate was investigated in this study. Combined and at different mixing ratios (100:0, 80:20, 60:40) treated under anaerobic reactor. The influence residence time, fraction initial pH were determined view COD color removal. Response Surface methodology (RSM) Box–Behnken design (BBD) employed to determine conditions for higher simultaneous removal color. highest satisfied 8.6, time 9 days while ratio 77:23. efficiencies realized 70% 72%...
Antiviral drugs such as lamivudine have been globally identified in the environment and marked emerging pollutants of concern due to their bioactive extremity. Following therapeutic uses, approximately 70% oral dose is eliminated renally parent drug. Concerns has raised for neighbouring aquatic bodies effluent produced from production plants containing high concentrations antiviral drugs. drugs, lamivudine, are extremely bioactive, prompting interest urgent removal environment. The purpose...
Microplastic pollution (MPs) emerged as a significant environmental concern due to its persistent nature. These MPs particles endure in waters, soils, and even the atmosphere, posing potential threats entire ecosystem. Aquatic organisms are at risk of ingesting MPs, leading accumulation tissues, ultimately affecting food chain. This study aims provide an overview sources distribution, impacts. have been documented various substances such bottled water, salts, seafood, air. However, full...
Abstract The quest to synthesize safe, non-hazardous Ag–ZnO nanoomposites (NCs) with improved physical and chemical properties has necessitated green synthesis approaches. In this research, Launaea cornuta leaf extract was proposed for the of NCs, wherein used as a reducing capping agent. antibacterial activity prepared investigated against Escherichia coli Staphylococcus aureus through disc diffusion method. influence temperature, pH, precursor concentration on NCs antimicrobial efficacy...
Scientific interest in antimicrobial pollutants, such as ciprofloxacin, has increased. Due to spread of antibiotic-resistant bacteria, resistance genes, and their dissemination the environment. Therefore, remediation is necessary ensure ecological sustainability. The current study aimed optimise removal ciprofloxacin from synthetic water using jamun seed (JS) (Syzygium cumini) biochar a response surface methodology (RSM). Result indicates elimination efficiency ranged between 32.46 94.95%,...
This study aimed to identify and quantify the total dust exposure underground miners in Mererani, Tanzania, its composition generate evidence for informed decision- policy-making. The Analytical Air Monitoring System (AMS) was used collection, analysis conducted gravimetrically. analysed using Inductively Coupled Plasma Optical Emission Spectroscopy. results showed significant variation levels across different mining zones, with inhaling up 1859 mg of over an 8-hour period drilling zones...
