This study presents an analysis of soil contamination caused by Ni, Zn, Cd, Cu, and Pb at municipal solid waste (MSW) landfills, with a focus on ecological risk assessment. The approach aims to assess how different landfill practices environmental conditions affect potentially toxic elements (PTEs) associated risks. Soil samples were collected from MSW landfills in Poland the Czech Republic. research included comprehensive assessment PTEs soils context global regulations. degree was assessed using indices: Geoaccumulation Index (I geo ), Single Pollution (Pi), Nemerow (PN), Load Capacity Pollutant (PLI). determined Risk (ERi) Sum Individual Potential Factors (ERI). maximum values indicators observed for Radiowo as follows: I = 4.04 P i 24.80 PN 18.22 PLI 2.66, ER 744 ERI 771.80.

Impact of soil physicochemical factors and heavy metals on co-occurrence pattern of bacterial in rural simple garbage dumping site

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 280, P. 116476 - 116476

Published: May 31, 2024

Rural waste accumulation leads to heavy metal soil pollution, impacting microbial communities. However, knowledge gaps exist regarding the distribution and occurrence patterns of bacterial communities in multi-metal contaminated profiles. In this study, high-throughput 16 S rRNA gene sequencing technology was used explore response various pollution rural simple dumps karst areas Southwest China. The study selected three habitats center, edge, uncontaminated dump evaluate main factors driving change community composition. Pollution indices reveal severe contamination across all elements, except for moderately polluted lead (Pb); severity ranks as follows: Mn > Cd Zn Cr Sb V Cu As Pb. Proteobacteria, Actinobacteria, Chloroflexi, Acidobacteriota predominate, collectively constituting over 60% relative abundance. Analysis Chao Shannon demonstrated that center boasted greatest richness diversity. Correlation data indicated a predominant synergistic interaction among landfill's community, with higher number positive associations (76.4%) compared negative ones (26.3%). Network complexity minimal at dump's edge. RDA analysis showed Pb(explained:46%) Mn(explained:21%) were key causing difference composition edge area dump, AK(explained:42.1%) Cd(explained:35.2%) dump. This provides important information understanding patterns, co-occurrence networks, environmental mechanisms landfill soils under stress, which helps guide formulation treatment remediation strategies.

Systematic and scientific assessments on heavy metal pollution are greatly important to protecting the coastal eco-environment. In this paper, spatial distribution, degree, ecological toxicity possible sources of eight elements collected from 126 marine 715 terrestrial surface sediments surrounding Dingzi Bay were analyzed by obtaining concentration measurements. The results revealed that concentrations metals followed a pattern: inner bay > areas outer bay. Cr, Ni, Cu, Zn, Cd, Pb, Hg found accumulate in fine particles (<0.063 mm), while As showed an association with specific (>0.25 mm <0.016 mm).
