A total of 895 surface soil samples （0-20 cm） and five road-dust were collected in a typical vanadium-titanium magnetite mining area Hongqi-Damiao catchment the Chengde City analyzed for 12 heavy metals （Cu, Ni, Cd, Cr, Pb, Zn, Hg, V, Ti, Mn, As, Co） their chemical speciation. The accumulation ecological risk characteristics （HMs） clarified by geological accumulative index, potential index （RI）, assessment coding （RAC）, modified Nemerow integrated （mNIER）. Multiple statistical methods...
Mineral resource bases have dual properties, e.g., mineral resources and environmental pollution. The latter could be classified into natural anthropogenic pollution based on identifying the spatial distribution characteristics sources of heavy metals in soil. Hongqi vanadium titano-magnetite base Luanping County, Luanhe watershed, was taken as research object. geo-accumulation index (Igeo), Nemerow comprehensive (PN), potential ecological risk (Ei) were utilized to assess soil metal...
A total of 351 surface soil samples (0-20 cm) were collected from the Luanhe River Basin in Chengde City (a typical area concentrated mineral resources) and analyzed for 12 heavy metals (Cu, Ni, Cd, Cr, Pb, Zn, Hg, V, Ti, Mn, As, Co). The geochemical baseline values determined using reference element method cumulative frequency curve method. Furthermore, spatial structure distribution characteristics assessed based on PCA geostatistical analysis. accumulation metal pollution different types...
A total of 86 soil samples, corn kernel 50 tailings and 33 ore rock samples were collected in reclaimed land surrounding areas typical vanadium-titanium magnetite located the Chengde Central Region analyzed for 14 elements (P, Fe, Cu, Ni, Cd, Cr, Pb, Zn, Hg, Ti, Mn, Mo) speciation heavy metals. This study investigated bioaccumulation translocation characteristics metals a soil-maize system based on descriptive statistical analysis, geological accumulative index, bioconcentration factors,...
A large number of intermediate basic volcanic rocks and porphyry Cu-Mo deposits as well volcanic-hosted magnetite deposit have been recently discovered in the Xilekuduk area. However, no reports concerning petrogenesis age or their relationship with mineralization published to date. The purpose this study was make up for absence previous studies on Devonian activities area confirm between two stages so provide important theoretical basis mineral exploration. Based research results zircon...
The multi-environment media of water, surface soil and vadose zone samples were collected in the upstream Miyun Reservoir, Luanping Basin Chengde City, Hebei Province. aim was to identify pollution source, ratio, spatial distribution, migration, transformation characteristics nitrogen groundwater. Hydrogeochemistry, total nitrogen, dissolved nitrate analysis a multi isotope tracer technique δ15 N-NO3 δ18O-NO3, δ34S-SO4 δ18O-SO4, δ14 C, combined with land-use type geostatistics, used study....
Water contamination traceability is of great significance for the sustainable water resource management Chengde, which a critical conservation area in northern China. By combining geostatistical, hydrochemical analysis, multi-isotope approach and Bayesian isotope mixing (SIAR) model, this study investigated NO3— sources revealed impact soil nitrogen pool on enrichment, transformation processes rural-agricultural-mining superposition watershed. Approximately 30.50% samples exceeded WHO...
Strawberry Plant Area in Chengde is located the Jingcheng Golden Tour Corridor. The main plantings area are strawberries, however recent years, there have been problems such as insufficient supply of surrounding land and specialization pesticide formulations. In this study, through testing analysis 30 nutrients total metal elements, 7 efficient statuses pH soil organic matter surface samples, status nutrients, environment quality comprehensive evaluated region. Based on complete water...
