Geospatial Analysis, Source Apportionment, and Ecological–Health Risks Assessment of Topsoil Heavy Metal(loid)s in a Typical Agricultural Area

Agriculture, Journal Year: 2025, Volume and Issue: 15(9), P. 913 - 913

Soil environmental protection has become a pressing issue for sustainable development. This study collected 153 topsoil samples from typical agricultural area to evaluate the contamination characteristics of heavy metal(loid)s (HMs), identify their potential sources, and assess associated ecological human health risks. The results showed that mean concentration HMs was in order Zn > Cr Ni Pb Cu As Cd Hg; all were below background levels, except Cd. geo-accumulation index (Igeo) improved Nemerow (INI) revealed overall pollution level considered as no or slight contamination, while posed low risk according hazard factor (Ei) (PERI). In addition, three main sources identified through positive matrix factorization (PMF) model: natural source (48.2%; contributed As, Ni, Cu, Pb, Zn), coal burning waste disposal (24%; Hg Cd), activities (27.8%; Cr). (HHR) assessment model Monte Carlo simulation applied risks, suggested children faced higher risks than adults, with 45.83% exceeding non-carcinogenic acceptable limit. contributors carcinogenic respectively. findings local management development agriculture.

Source-Oriented Health Risks and Distribution of BTEXS in Urban Shallow Lake Sediment: Application of the Positive Matrix Factorization Model

Water, Journal Year: 2024, Volume and Issue: 16(16), P. 2302 - 2302

Published: Aug. 15, 2024

The degradation of sediments in urban environments worldwide is driven by population growth, urbanization, and industrialization, highlighting the need for thorough quality assessment management strategies. As a result these anthropogenic activities, benzene, toluene, ethylbenzene, xylenes, styrene (BTEXS) are persistently released into environment, polluting sediment. This study employed self-organizing maps (SOMs), positive matrix factorization (PMF), Monte Carlo simulation source-oriented health risks to comprehensively investigate sediment an shallow lake mid-sized city central Serbia. results indicated mean ∑BTEXS concentration 225 µg/kg, with toluene as dominant congener, followed m,p-xylene, o-xylene, styrene. Three contamination sources were identified: waste solvents plastic due intensive recreational vehicle exhaust from heavy traffic surrounding lake. Both non-carcinogenic carcinogenic below permissible limits. However, children more susceptible risks. Benzene most responsible both groups. this can help researchers find suitable perspective on dynamics impacts BTEXS sediments.
