The spontaneous discharge of pollutants or toxicants into the ecosystem as a result various anthropogenic activities is alarming, this necessitates drastic cheap, and eco-friendly clean-up approach. Out all methods, adsorption has proven to be most effective. batch adsorptive removal Thymol Blue (TB) dye from aqueous solutions examined in study utilizing calcined snail shells (CalSS). With aid SEM, EDS, XRD, FTIR, synthesized adsorbent was for different physicochemical characteristics. A...
In this study, nine PPCPs were widely detected in surface and groundwater. Ciprofloxacin methylparaben the most dominant antibiotic paraben compounds, respectively, with ciprofloxacin posing a high health risk to all population groups.
This study provides, for the first time, data on distribution and toxicity of catechol (CAT) hydroquinone (HQ) in drinking water sources from Africa.
Mycotoxins in drinking water are neglected pollutants that have serious health implications when ingested.
Improved endocrine disrupting compound (EDC) removal is desirable in municipal wastewater treatment plants (MWWTPs) although increased does not always translate into reduced biological activity. Suitable methods for determining reduction activity of effluents are needed. In order to determine which MWWTPs the most effective at removing EDC activities, we operated three configurations pilot sized reactors (conventional activated sludge, CAS; nitrifying NAS; and nutrient removal, BNR)...
Ficussur (Moraceae) is an indigenous medicinal plant with a wide distribution in Africa. In this study, the nutritional potential fruit of to meet domestic food demands and reduce insecurity KwaZulu-Natal. South Africa, was investigated. The proximate composition concentrations metals edible fruits collected from eight different sites KwaZulu-Natal were determined assess for value growth soil evaluate impact quality on elemental uptake. contained high levels moisture (88.8%) carbohydrates...
The major part of textile processes is based on chemical reactions carried out in aqueous heterogeneous systems which eventually generates effluents extremely variable composition and constitute an environmental risk concern. This study, focused investigating the characteristic effluent from industry about 1577 m3 wastes per day effectiveness wastewater treatment technique practiced. Wastewater samples were collected at four different outlets within company premises twice two months...
The efficacy of three different wastewater treatment configurations, conventional activated sludge (CAS), nitrifying (NAS) and biological nutrient removal (BNR) for selected micropollutants from authentic was investigated. processes were also characterized based on their proficiency to reduce the estrogenic activity influent using in vitro recombinant yeast assay. efficiency trimethoprim improved with complexity process configurations. Ibuprofen, androstendione, sulfamethoxazole,...
Ficus sur Forssk. (Moraceae) is a medicinal plant species found in Africa and the leaves are used traditional medicine as blood builder to boost iron levels for treatment of anaemia, skin disorders sexually transmitted diseases. In this study, phytochemical investigation was conducted on F. antioxidant properties isolates extracts were evaluated. The major secondary metabolites that isolated from fruits triterpenoid (lupeol), sterol (β-sitosterol), phaeophytin (phaeophytin a) flavonoid...
A pilot scale biological nutrient removal (BNR) process, batch experiments and modeling exercises were employed to investigate the biotransformation of trimethoprim (TMP) in a BNR activated sludge process. The concentrations active microbial groups - ammonia oxidizing bacteria (AOB), ordinary heterotrophic organisms (OHOs) polyphosphate accumulating (PAOs) bioreactor quantified through bioreactor. overall TMP efficiency for process was 64 ± 14% while efficiencies anaerobic, anoxic aerobic...
The concentrations of Cr, Cu, Fe, Mn, Pb, Ni, V and Zn in sediment, surface groundwater were determined a total 180 samples acquired bi-monthly for one year to evaluate the impact bitumen spills. Principal component analysis (PCA) cluster (CA) also used identify possible sources contamination. heavy metals groundwater, water sediment as follows: Fe > Mn Cu Pb Ni Cr respectively. average found be above World Health Organization (WHO) drinking-water quality standard 0.1, 0.003 0.4 mg L−1...
Ficus burtt-davyi (Moraceae) is a medicinal plant species indigenous to Southern Africa. In this study, phytochemical and cytotoxic investigation on F. was conducted evaluate its ethno-medicinal use. The study of the fruits yielded triterpenoids (lupeol α-amyrin). evaluation done methanolic extracts selected compounds, lupeol, α-amyrin, lupeol acetate (+)-catechin isolated from stem bark fruits. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cell viability assay carried...
