Heavy metal pollution is a serious problem worldwide. In this study, 41 soil samples and 32 cabbage were collected from the area surrounding Jinsha coal-fired power plant (JCFP Plant) in Guizhou Province, southwest China. Pb, Cd, Hg, As, Cu Cr concentrations analysed to study sources risks of heavy metals around plant. The results indicate that JCFP Plant contributes Cu, nearby soils, particularly Hg pollution. soils both croplands forestlands derive mainly crustal materials or natural...
The speciation and activity of heavy metals in farmland were changed with the different soil properties flooded environment, especially complex rainy environment Guizhou Province. objective this study was to explore concentrations a variety metal those rhizosphere at growth stages Brassica campestris L. Karst mountainous area. Tessier's five-stage sequential extraction procedure, potential ecological risk index, Bayesian network, accumulation factors, translocation factors laboratory...
The content of heavy metals in the soil Guizhou Province, which is a high-risk area for metal exposure, significantly higher than that other areas China. Therefore, objective this study was to evaluate ability CaCO3 and clay accumulate topsoil sample collected from Lixisol using method indoor simulation. results showed contents Cu, Zn, Cd, Cr, Pb, Hg As were 10.8 mg/kg, 125 0.489 23.5 22.7 58.3 mg/kg 45.4 respectively. pH values increased with concentration soil, fluctuation weak after...
Abstract Agricultural soil serves as a crucial reservoir for microplastics (MPs), necessitating an understanding of their global‐scale environmental impacts and potential risks that they pose to agricultural crops. Little is known about the impact MPs in soils, compared with aquatic sediments, especially effects on crop traits. The purpose our study was explore whether different types, concentrations, sizes, exposure time MPs, well conditions (such pH or organic matter concentration), have...
The migration and driving factors of microplastics (MPs), as an emerging pollutant, have been reported in plateau lakes. However, whether MPs can accumulate to extreme degree the local aquatic organisms lakes remains unclear. Therefore, present study mainly aims investigate accumulated tissues grass carp well reveal their processes Caohai watershed, a typical lake southwest China. Density flotation (saturated NaCl solution) laser direct infrared imaging spectrometry were used analyze...
The Wanshan mercury (Hg) mine in Guizhou Province is one of the main Hg-producing mines China, resulting serious Hg pollution soil and wastewater. Therefore, present study mainly aimed to investigate current degree heavy metal compared microbial diversity its surrounding environment. results showed distribution load index values was low west high east. northwestern (Aozhai River), northern (Meizi Stream), southwestern parts area Erkeng did not reach moderate pollution. Mercury accounted for...
The concentrations of the heavy metals Pb, Cd, Cr, Hg, As, Cu and Zn in soil locally produced grain (rice) were determined paddy rice around an abandoned high-arsenic coal mine area Xingren county, southwest China. health risk assessment was used to assess multimedia multipathway risks HM exposure study area. results showed that Pb Cd all higher than corresponding limits for HMs In terms accumulation transfer capacity, more likely from roots rice, its strong mobility may pose potential local...
Highly promising artificial intelligence tools, including neural network (ANN), genetic algorithm (GA) and particle swarm optimization (PSO), were applied in the present study to develop an approach for evaluation of Se(IV) removal from aqueous solutions by reduced graphene oxide-supported nanoscale zero-valent iron (nZVI/rGO) composites. Both GA PSO used optimize parameters ANN. The effect operational (i.e., initial pH, temperature, contact time concentration) on efficiency was examined...
The aim of this study was to understand the C:N:P stoichiometry three rare tree species that grow at different elevations Mount Fanjing Nature Reserve in Guizhou Province, China. We analyzed C, N and P new stems, leaves soil two coniferous species, Abies fanjingshanensis Taxus chinensis var. mairei, hardwood Davidia involucrata. total-C, total-N, hydrolyzed-N available-P contents forest soils were higher altitudes, with median values for A. > T. mairei D. involucrata soil. C:N, C:P N:P...
This study aims to investigate the impact of diverse forest stand types and soil depths on ecological stoichiometry characteristics, shedding light nutrient limitations cycling patterns within mid-subtropical ecosystem in southwest China during spring. The research focused four representative stands situated Fanjing Mountain: Castanopsis fargesii (C. fargesii), Cyclobalanopsis multiervis multiervis), argyrotricha argyrotricha), Rhododendron argyrophyllum Franch (R. argyrophyllum).
