Biochar impacts on carbon dioxide, methane emission, and cadmium accumulation in rice from Cd-contaminated soils; A meta-analysis

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 274, P. 116204 - 116204

Published: March 14, 2024

Climate change and cadmium (Cd) contamination pose severe threats to rice production food security. Biochar (BC) has emerged as a promising soil amendment for mitigating these challenges. To investigate the BC effects on paddy upon GHG emissions, Cd bioavailability, its accumulation, meta-analysis of published data from 2000 2023 was performed. Data Manager 5.3 GetData plot Digitizer software were used obtain process selected parameters. Our results showed significant increase 18% in pH with sewage sludge application, while 9% organic carbon (SOC) using bamboo chips BC. There reduction bulk density (8%), but no observed porosity, except wheat straw which reduced porosity by 6%. Sewage significantly dioxide (CO2) 7–8% municipal biowaste methane (CH4) emissions 2%. In case heavy metals, sunflower seedshells-derived materials husk bioavailable soils 24% 12%, respectively. uptake roots lowered considerably addition kitchen waste (22%), peanut hulls (21%), corn cob (15%) based Similarly, cotton sticks, waste, hulls, restricted translocation shoots 22%, 27%, 20%, 19%, respectively, sawdust husk-based effective reducing accumulation grains 25% 13%. Regarding yield, sticks-based increased yield 37% Cd-contaminated soil. The demonstrated that is an multi-pronged strategy sustainable resilient cultivation lowering greenhouse gas improving yields under increasing threat climate change.

IAA is more effective than EDTA in enhancing phytoremediation potential for cadmium and copper contaminated soils

BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Published: Aug. 29, 2024

Enhanced phytoremediation offers a rapid and eco-friendly approach for cleaning agricultural soil contaminated with copper cadmium which pose direct threat to food scarcity security. The current study aimed compare the effectiveness of two commonly used additives, IAA EDTA, remediation (Cu) (Cd) soils using sunflower maize. plants were cultivated in pots under controlled conditions four sets treatments: control (0), Cu50/Cd50, Cu50/Cd50 + IAA. results showed that mg/kg drastically compromised potential both plants, as evident by reduced shoot root length, lower biomass. However, augmentation EDTA or improved tested parameters. In sunflower, enhanced accumulation Cu Cd 58% 21%, respectively, plant biomass 41%, compared treatment. exhibited higher 64% 25%, 43%. case maize, was superior 87% 32% increased 57%, Our findings demonstrate foliar is more effective than enhancing maize Cd.

Physicochemical and Spatial Distributions of Trace Elements and Organochlorine Compounds in Lake Idku Water, Egypt

Water Air & Soil Pollution, Journal Year: 2025, Volume and Issue: 236(2)

Published: Jan. 23, 2025

Abstract This study aimed to characterize the water quality of 4 sites in Lake Idku, third largest wetland region Egypt regarding physicochemical indicators, spatial distributions certain trace elements and organochlorine compounds (OCs). Most tested indicators were above permissible limits River Nile except nitrate was lower than limits. The distribution concentrations Fe, Cu, Zn, Mn, Pb, Cd significantly differed (p > 0.05) among sampling sites, where mean these all ranged from 0.0226–0.0392, 0.010–0.098, 0.3570–1.0160, 0.084–0.942, 0.015–0.024, 0.011–0.023 mg/L, respectively. west site lake contained highest contents elements, followed by east, north, then south sites. Water collected had Fe while those Cd, samples east Mn. Mn which exceeded Egyptian regulations, levels that met regulations. Regarding residues OCs, ∑OCs can be grouped descending order as follows: north site, with values 5.632, 5.230, 4.731, 4.650 µg/L, All detected OCs maximum acceptable compared WHO standards 0.1 μg/L, for p,p'-DDT, p,p'-DDD, p,p'-DDE at levels. In conclusion, Idku may risk biota humans, monitoring, management, mitigation strategies are urgently required prevent further pollution restricting discharge industrial agricultural wastewater into Idku.

Heavy Metal Contamination in Arenillas Ecological Reserve Soils: Correlation and Conservation Impact

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

Published: March 12, 2025

ABSTRACT This study addresses the critical knowledge gap regarding heavy metal contamination in soils of Arenillas Ecological Reserve (AERv), located on southwest coast Ecuador. Despite being a fragile and highly biodiverse ecosystem, little is known about magnitude, spatial distribution, drivers this reserve. Soil samples were collected at depth 0 to 10 cm from mangrove areas (MANg), salt marshes (SMe), dry forests (Df) assess concentrations copper (Cu), manganese (Mn), iron (Fe), zinc (Zn), lead (Pb), chromium (Cr) their correlation with physicochemical properties. Analytical methods included one‐way ANOVA, Pearson correlation, cluster analysis (CA), application geo‐accumulation index ( Igeo ) pollution load PLI quantify levels. The results reveal elevated metals MANg, SMe, southern forest (Df‐S5), exceeding thresholds reported previous studies. Notably, Zn Pb levels range high very across reserve, MANg most impacted by all studied. accumulation patterns are closely linked soil properties such as silt clay content, porosity, pH, organic matter, which influence retention mobility. primarily attributed anthropogenic activities, including shrimp farming, conventional agriculture, pollutants originating mining, domestic, industrial discharges nearby urban areas. These findings underscore urgent need for targeted restoration conservation measures safeguard reserve's biodiversity ecosystem services. They also highlight necessity updated regulations mitigation strategies manage effectively, offering foundation sustainable management practices AERv other protected
