The coprecipitation of heavy metals (HMs) with Fe(III) in the presence dissolved organic matter (DOM) is a crucial process to control mobility HMs environment, but its underlying immobilization mechanisms are unclear. In this study, Cr(III) by straw-derived DOMs under different Fe/C molar ratios, pHs, and ionic strengths was investigated using scanning transmission X-ray microscopy (STXM) ptychography absorption near-edge structure (XANES) spectroscopy. results showed that retention enhanced...

Heavy metals of sort Pb and Cd are utmost importance significantly in Nigerian public health. Others such as Fe Zn available the environment typically contribute to sustenance ecosystem. The present study determined bioaccumulation health risks some heavy which include Zinc (Zn), Cadmium (Cd), Iron (Fe) Lead (Pb) Fish (Oreochromis niloticus) with their levels sediment water Challawa River, Kano, Nigeria. were measured using atomic absorption spectrophotometry. water, fish samples analysed...

Phase transformation of ferrihydrite to more stable Fe (oxyhydr)oxides, catalyzed by iron(II) [Fe(II)], significantly influences the mobility heavy metals [e.g., chromium (Cr)] associated with ferrihydrite. However, impact organic matter (OM) on behavior Cr(III) in Fe(II)-catalyzed and underlying mechanisms are unclear. Here, coprecipitates Fe(III), Cr(III), or rice straw-derived OM was studied at nanoscale molecular levels using Cr K-edge X-ray absorption spectroscopy spherical aberration...

Heavy metals are widespread in all parts of the environments, thereby polluting soil, water, and biota finally causing harm to human health. However, humans prone a mixture elements other than single element. Thus, study was aimed at determining hematological indices oxidative response from exposure multi-elements mice. Twenty-five (25) male mice were grouped into 5 groups 1mg Cd (Group I), Pb II), 2mg Cd+1mg III), Pb+1mg IV) /kg b.w amended mouse chows control V), administered. Following...

Abstract Background Artisanal gold mining has been one of the major contributors to soil pollution. These types have potential environmental implications and varying degrees health risk due agricultural product cultivation. The contamination level Pb in soils under cultivation by maize spinach from mines Abare, Dareta Bagega Anka local government Zamfara state was examined. Three levels depths (0–21, 21–40 41–60 cm) study sites were considered for vertical distributions Pb. samples digested...

Mercury (Hg) is a highly toxic contaminant posing serious ecological and human health risks. This study investigates the Hg transfer characteristics prediction models in soil–lettuce system, employing bioconcentration factors (BCF), path analysis (PA), Freundlich-type functions. A pot experiment was conducted greenhouse, where lettuce grown range of Chinese agricultural soils (n = 21) deliberately spiked with using Hg(NO3)2 solution. The results indicated that Hg-spiked acidic (pH < 6.5)...

Under the current context of reducing chemical N input in agriculture, it is important to investigate better allocation different growth stages crops. The plants were subjected sufficient and reduced soil water regimes interaction with two application proportions applied at vegetative reproductive tomato plants, respectively. In terms impact, across proportion treatments, treatments significantly decreased leaf biomass by 33% meanwhile remarkably stomatal conductance leaves, which...

Illegitimate artisanal gold mining quite often results in elevated lead (Pb) concentrations and residential areas close to ore sites, which exposes the communities varying degrees of health environmental challenges.Here,mining soils from Abare, Dareta Bagega, Anka local government,Zamfara state's exposed communities, were examined for total Pb concentration.Three replicates soil four different fields carefully selected sampling surface layer 0 21 cm.All thesoil samples digested analysed...

Plastic pollution is one of today's most serious global issues in the aquatic environment and organisms, including entanglements, ingestion, possible toxicity. The study was carried out to screen identify microplastics some tissues fish species from Sallari Hauren Shanu burrow pits Kano metropolis. A total 60 samples comprising two species; Oreochromis niloticus (n = 30) Tilapia zilli 30), were collected sampling sites (Sallari Shanu). fishes' gastrointestinal tract, gills muscle collected,...

The discharge of industrial wastewater represents a significant source environmental pollution, particularly in developing regions where regulatory enforcement is often insufficient. This study examined the chemical characteristics effluent discharged from three locations (LA, LB, and LC) close to Challawa Industrial Area Kano, Nigeria, determined their effects on nearby soil. Effluent samples were analysed for pH, biochemical oxygen demand (BOD), phosphates (PO), nitrates (NO-N) critical...

Heavy metals contamination of soil is a recurrent issue in terrestrial ecosystems that are polluted by consequences process particles augmented and metalloids, including industrial activities. Consequently, we investigated the distribution between levels heavy soils tissues earthworm species from metal-related occupational sites. Texturally, were classified as sandy-loam, while, level across different sampling locations followed decreasing trend; Zn > Cr Cu Fe Pb Ni Cd found above threshold...

Accumulating evidence points to the multidimensional role of ultraviolet radiation in plant growth and development. Ultraviolet-A (UV-A), as main component UV nature, has a wide range effects on plants. As there is some its positive effect regulator controlled environment, long been interest use UV-A agriculture. However, remains largely unknown number studies looking at environment still too small. The review carried out here also includes other components growth, morphology physiology,...
