Bioaccumulation of Atmospherically Deposited Cadmium in Soybean: Three-Year Field Experiment Combined with Cadmium Isotopes

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 24, 2024

Atmospheric deposition plays a significant role in introducing cadmium (Cd) into agroecological systems; however, accurately determining its accumulation crops through foliar and root uptake presents challenges. This study investigated the bioaccumulation of atmospherically deposited Cd soybean using three-year fully factorial atmospheric exposure experiment incorporating isotope analysis. Results shown that accounted for 1-13% soil pools, yet contributed 11-72% to tissues during growing seasons. Over course ranging from 1 3 years, no notable variations were observed concentrations solutions tissues, nor ratios. Newly was major source plants, bioavailability rapidly aged soils. enriched lighter isotopes induced negative shifts plants. By employing an optimized mixing model conjunction with mass balance approach, 13-51%, 16-45%, 21-56% stem, leaf, seed, respectively. highlights substantial contribution levels controlling as potential strategy systems experiencing high deposition.

CaO-modified hydrochar reduces soil cadmium bioavailability by altering soil properties, shifting bacterial community, and promoting microbial metabolisms

Environmental Technology & Innovation, Journal Year: 2024, Volume and Issue: 35, P. 103698 - 103698

Published: May 27, 2024

The efficient remediation of cadmium (Cd)-contaminated soil is great significance for reducing the threats to ecosystem and human health. At present, carbon-rich hydrochar with abundant oxygen-containing functional groups as environmental material gains numerous attention due its cost-effectiveness sustainability. A pot experiment was performed investigate Cd immobilization efficiency microbial response in presence pristine corn stalk CaO-modified hydrochars. Results showed that compared hydrochar, fresh biomass plant shoot promoted by 0.904-15.6% amendment, bioavailable content correspoding uptake were decreased 8.19-16.2% 4.18-17.0%, respectively. Additionally, relative abundance Actinobacteriota benefiting elevated from 30.3% 34.4-44.6% after amendment. metabolisms (e.g., carbohydrate metabolism, amino acid citrate cycle) also enhanced contributing reduce bioavailability. Redundancy analysis revealed bacterial community structure rhizosphere significantly influenced dissolved organic carbon electric conductivity (p<0.05). Overall, cost-effective reduced phytotoxicity a promising metal-contaminated soil.

The long-term use of copper (Cu)-based fungicide sprays in orchards is associated with changes soil Cu levels. However, there a gap knowledge regarding the potential accumulation and impacts on microbial structure. This study assessed possibility different avocado orchard farms further evaluated effect activities. Soil levels were quantified Tauranga Northland, three analysed each experimental location. All both sites received Cu-based for over eight years. samples collected at 0–20 cm depth from all six orchards. total bioavailable Cu, chemical properties, biomass, dehydrogenase activity, alkaline phosphatase acid activity measured. results revealed that concentrations 81.3 0.32, 196.7 0.82, 33.6 0.31 mg kg−1 Farms 1, 2, 3, respectively.
