Contamination and Spatial Distribution of Metal(loid)s in the Stream Sediment near the Greenhouse

Horticulturae, Год журнала: 2024, Номер 10(4), С. 312 - 312

Опубликована: Март 22, 2024

As greenhouse horticulture continues to increase in South Korea, the effects of metal(loid)s from wastewater discharges on stream sediments were analyzed. A total 106 samples analyzed for cadmium (Cd), boron (B), copper (Cu), nickel (Ni), lead (Pb), zinc (Zn), chromium (Cr), manganese (Mn), and iron (Fe). The coefficient variation (CV) components was 96.58% Mn, 93.40 Zn, 62.47 B, 58.90 Pb, 58.14 Cd, suggesting anthropogenic sources. Correlation analysis suggested a cumulative source Cd-Zn cluster an Cu, Mn. contamination factor (CF) need trace Pb (3.21 ± 1.89) B (1.33 0.83) EF (3.30 1.81) (1.44 0.94). analytical results identify sources Cd. high Cd suggests influence mining areas, traffic, fertilizers, pesticides, fossil fuels greenhouses, addition mines. confirmed impact facility’s vegetable further examine Fe, etc. By utilizing facility ecological restoration other agricultural uses, we aim prevent sediment pollution realize sustainable environment.

A Multivariate and Geographic-Information-System Approach to Assess Environmental and Health Hazards of Fe, Cr, Zn, Cu, and Pb in Agricultural Soils of Western Saudi Arabia

Sustainability, Год журнала: 2025, Номер 17(4), С. 1610 - 1610

Опубликована: Фев. 15, 2025

This study evaluates the environmental and health hazards associated with presence of Fe, Cr, Zn, Cu, Pb in agricultural soils from Makkah region western Saudi Arabia. Soil samples were collected 32 farms predominantly cultivating dates vegetables analyzed for heavy metals (HMs) using inductively coupled plasma-atomic emission spectrometry (ICP-AES). Multivariate statistical analysis, Geographic Information Systems (GIS), various contamination indices employed. The average HM concentrations arranged descending order as follows: Fe (35.138 mg/kg), Zn (69.59 Cu (55.13 Cr (47.88 (6.09 mg/kg). Contamination indicated considerable enrichment deficient to minimal other HMs, though a few individual showed higher factor (EF) values. Risk assessments revealed low-level risk HMs soils. analyses suggested that primarily originated natural geological processes, anthropogenic contributions particularly evident Cu. Hazard index (HI) values ranged 0.0003 0.0691 adults 0.003 0.6438 children, remaining below threshold 1.0, which indicates no significant non-carcinogenic risk. Lifetime cancer estimates 1 × 10−6, while those 10−6 10−4, indicating tolerable carcinogenic levels exceptions children. is it provides critical baseline data on region, offering insights into soil pollution. findings contribute broader understanding serve foundation developing sustainable practices targeted mitigation strategies minimize risks regions similar conditions.

Heavy Metal Accumulation in Maize and Wheat in Acidic Soil: A Comparative Study

Sustainability, Год журнала: 2025, Номер 17(5), С. 2084 - 2084

Опубликована: Фев. 28, 2025

Maize and wheat grains are at significant risk of accumulating excessive heavy metals in acidic soils, but relatively few comparative studies have been conducted on the two. This study employed Spearman correlation analysis, random forest modeling, structural equation modeling to systematically investigate interdependences between soil properties metal accumulation (Cd, Cr, As, Pb, Hg) cereal grains. The results revealed distinct patterns content sequences maize grains: exhibited Cr > Pb As Cd Hg, while followed Hg. Bioconcentration factor (BCF) differed significantly, showing Hg versus wheat. Soil cation exchange capacity demonstrated strongest influence both crops. Arsenic mechanisms displayed species-specific dependencies, with primarily regulated by organic matter clay content. Notably, a positive (p ≤ 0.05) concentrations was observed crops, suggesting potential homologous pollution sources. These findings elucidate crop-specific governed physicochemical properties. demonstrates that under similar growing conditions, (BCF = 0.068) exhibits weaker ability accumulate compared 0.467). Moreover, showed responses properties, particularly their Cd. By addressing contamination this work supports development safer agricultural practices improved crop quality control.

Geo-Spatial Insights into Heavy Metal Contamination and Ecological Implications in River Sediments: Identifying Agrochemical Impacts Through Pollution Indices in Morocco’s Sidi Allal Tazi Region, Sebou Basin

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Апрель 18, 2025

Sediments in agricultural ecosystems serve as critical indicators of environmental pollution, particularly regions subjected to intensive practices. This research evaluates the hazards and implications heavy metal (HM) contamination river sediments from Sidi Allal Tazi area within Morocco’s Sebou basin. Twenty sediment samples were extracted strategically designated locations, levels analyzed using a multi-index integration approach, multi-statistical analyses (MSA), Geographic Information Systems (GIS). The results revealed considerable spatial variability HM concentrations, with Cd As displaying highest levels. Statistical analysis, incorporating Principal Component Analysis (PCA), identified anthropogenic activities primary contributors contamination. Hierarchical Cluster (HCA) categorized metals based on common pollution pathways, while GIS mapping distribution across vulnerable areas. Pollution like Geo-accumulation Index (I_geo) well Load (PLI). that 75% sites under “very high pollution”, emphasizing severity Contamination Factor (CF) classified 90% 100% contamination”. Risk indices indicated significant ecological threats, contributing an RI exceeding 600 many areas, signifying risk”. These findings highlight urgent need for targeted mitigation strategies sustainable methodologies provides comprehensive framework assessing managing contamination, offering insights policymakers managers.

Heavy Metal Content in Substrates in Agricultural Biogas Plants

Agricultural Engineering/Inżynieria Rolnicza, Год журнала: 2023, Номер 27(1), С. 315 - 329

Опубликована: Янв. 1, 2023

Abstract The content of heavy metals in soil should be continuously monitored, especially organic crops. Exceeding the permissible concentrations these elements may lead not only to inhibition plant growth but also ingestion into organisms animals that feed on plants. Heavy usually enter via precipitation or manure. There is a noticeable increase interest digestate for fields fertilization. Therefore, authors decided test metal substrates (slurry and solid input) digestate. 15x3 samples tested showed trace amounts were present. study shows sum supplied digester with substrates. In most tested, did exceed 5 mg‧kg −1 . lowest cadmium (an average 0.28 ) observed slurry, highest 0.34 substrate fed digester. Slurry had mercury contents (average 0.012 5.8 ). concentration chromium was registered 3 this 0.3 higher than feedstock 0.5 slurry
