Abstract This study was conducted to investigate the speciation, bioavailability and environmental risk of heavy metals (HMs) in chicken manure (CM) water-washed swine (WSM) their biochars produced at different pyrolysis temperatures (200 800 °C). As temperature increased, remaining proportion, toxicity characteristic leaching procedure (TCLP), HCl diethylenetriamine pentaacetic acid (DTPA) HMs gradually declined. result proved that speciation (CMB) (WSMB) influenced by temperature. The...
The contamination of marine ecosystems with metal(loid)s is an increasing environmental concern, largely driven by anthropogenic activities, and poses a significant risk to the health human well-being. Geochemical background values represent typical concentrations trace elements observed in natural environment. utilization disparate gives rise evaluation outcomes. objective this study was investigate concentration profiles (Cu, Pb, Zn, Cr, Cd, As, Hg) along sediment core order obtain assess...
For the purpose of providing crucial theoretical support for guaranteeing food security and reaching low-carbon emissions, this study examines spatiotemporal evolution influencing factors eco-efficiency cultivated land use (ECLU) across 125 cities in Yangtze River Economic Belt (YREB) from 2005 to 2022. Utilizing models such as Super-SBM, spatial autocorrelation, standard deviational ellipse, regionally weighted regression, we investigate characteristics factors. The results indicate that...
The lowest concentrations, atmospheric fluxes, and enrichments of Sb in a Swiss bog were found peat samples dating from 8,020 to 5,320 14 C yr BP when inputs proportional those Sc effectively controlled by deposition soil dust. For comparison with these ancient samples, modern five rural areas Switzerland two remote Scotland Shetland are highly contaminated Sb, the order 30 80 times. “Lithogenic” concentrations calculated using background Sb/Sc ratio dwarfed at all sites “anthropogenic” Sb....
Motion-induced noise (MIN) caused by the mechanical vibration of air-core coil sensor (ACS) in geomagnetic field is an important element detection method helicopter transient electromagnetic (TEM) systems. The MIN level heavily influences result when its frequency range covers TEM signal base (25 Hz). To reduce MIN, frequencies between and signals need to be separated. Accordingly, ACS must decreased a below 25 Hz. Hence, cable parallel (CPACS), consisting structure (CPS) ACS, designed for...
Devising a low-cost and effective strategy to reduce Cd contamination of brown rice is critical achieve the safe production grain for human consumption. Accordingly, here field experiments were conducted at two sites evaluate effects applying humic acid (HA) foliage twice, booting full heading stage, on diminishing translocation cadmium (Cd) into grains. Besides measuring subcellular distribution in flag leaf polysaccharide composition cell wall, latter's types concentrations functional...
Antimony concentrations were measured in a core collected from Myrarnar, blanket bog on the Faroe Islands which has been accumulating peat for more than six thousand years. The vertical distribution of Sb indicates that it supplied to exclusively atmosphere. Despite proximity ocean, contribution marine aerosols amounts less ca. 10% natural inputs. Although contains four notable layers volcanic ash originating Iceland, these have not contributed significantly inventory. However, closely...
This study aimed to investigate the pollution of heavy metals in sediments park lakes Guangzhou, which is a large city with rapid urbanization, industrialization, and dense population South China. Thirty-two surface sediment samples were collected from seven different districts this city. The concentrations distributions Cr, Ni, Cu, Zn, Cd, Pb measured assess level enrichment toxicity sediments. factor showed that Zn severe all except for Dafu Shan Forest Park (DFS), geo-accumulation index...
The Jialing River watershed has seen substantial changes in habitat quality and land use throughout the last 20 years. It is yet unknown, however, how will react to these use. In this work, multi-scenario simulations for 2030 were carried out using PLUS InVEST models, evolution basin from 2000 2020 evaluated. study, following facts determined: (1) study area’s southern region mainly farmland, whereas northern part predominantly forestland. most significant a decrease of 1.46% grassland an...
