Abstract Rapid industrial development increases soil contamination risks in suburban agricultural areas; however, the extent and sources of heavy metal(loid)s pollution during this process are not well understood. This study investigated concentrations, spatial distribution, potential (As, Hg, Cd, Cr, Pb) wheat samples from an area. The found that Cd was main pollutant with highest enrichment factor 15.9 21.6% having concentrations exceeding China's limit 0.1 mg/kg. Soil As, Pb were concentrated northwest, while Cr high southeast. is more severe than other poses a slight ecological risk. Monte Carlo simulations showed hazard quotient for all five less 1, being highest. 1.35% children 0.87% adults exceeded carcinogenic risk level 0.54% exhibited above threshold Cr. Children most sensitive to exposure contaminated areas, metal(loid)s) concentration key influencing health risks. Source apportionment via PCA-APCS-MLR model correlation analysis revealed originated activities industrial-traffic. assessed pollution, risks, sources, residents consumption, providing evidence managing food safety.

Sediments are important heavy metal sinks in lakes, crucial for ensuring water environment safety. Existing studies mainly focused on well-studied leaving gaps understanding pollution patterns specific basins and influencing factors.We compiled comprehensive sediment contamination data from literature public datasets, including hydro-geomorphological, climatic, soil, landscape, anthropogenic factors. Using advanced machine learning, we analyzed typical factors to infer potential sources migration pathways of pollutants predicted levels with limited availability. Our analysis pollutant distribution revealed that Cd had the most extensive range, severe occurring Huaihe Yangtze River basins. Furthermore, identified distinct groups driving various metals. Cd, Cr, Pb were primarily influenced by human activities, while Cu Ni affected both natural factors, Zn tended more towards sources. predictions indicated that, addition highly polluted areas, risk is higher Xinjiang, Tibet Qinghai, higher. presented lower risks, except Basins. Temperature, wind, precipitation, precipitation rate, cation exchange capacity soil significantly impacted sediments, suggesting particulate migration, rainfall runoff, erosion likely main into sediments. Considering pathways, pollutants, propose strategies such as low-impact development promoting sustainable transportation mitigate pollution. This study provides latest insights Chinese lake offering references policy-making resource management.

For the first time, different pollution indices and a receptor model have been used to quantify eco-environmental health risk assessments as well identify sources of potentially toxic elements in soil along Barapukuria Coal Mine (BCM). Individual include enrichment contamination factors showing samples are moderately highly contaminated by arsenic, cobalt, chromium, copper, lead, zinc heavily sulfur. According geo-accumulation index, there is significant with arsenic (1.24 ± 0.38), lead (1.49 0.58), cobalt sulfur (1.63 0.38). Modified hazard quotient ecological factor values also suggest low moderate environmental hazards from same elements. The nemerow load index range 1.65 3.03, 0.82-1.23, 11-26, 77-165, 6.82-11.76 pollution, among other synergistic indices. Health assessment indicates that iron poses lower cancer for children than adults, while both face unacceptable risks inhaling or arsenic. Principal component phylogenetic cluster analysis extracted multiple linear regression absolute principal score (APCS-MLR) refer fact manganese, iron, titanium, nickel originated geogenic sources, coal mine effluents enrich like zinc, uranium, sulfur, thorium, phosphorous sourced agriculture. In addition, anthropogenic including agriculture activities, could pollute ecosystem. findings crucial regional national planners devising strategies mitigate element areas.

Mangrove forests are sources and sinks for various pollutants. This study analyzed the current status of heavy metal arsenic (As) pollution in mangrove surface sediments rapidly industrializing urbanizing port cities. Surface mangroves at Wulishan Port on Leizhou Peninsula, China, were using inductively coupled plasma emission spectrometry (ICP-AES) mass (ICP-MS) presence Cr, Pb, Ni, Zn, Cd, Cu, As, Hg. The Pollution load index, Nemerow Potential ecological risk index employed to evaluate pollutant. Multivariate statistical methods applied qualitative analysis pollutant sources, APCS-MLR receptor model was used quantification. indicated following results: (1) average content eight pollutants surpassed local background level but did not exceed Marine Sediment Quality standard. levels across four sampling areas ranked as Ⅲ > Ⅳ Ⅰ Ⅱ. area Ⅱ exhibited relatively lower with grain size dominated by sand, which conducive adsorption enrichment. (2) factor cluster analyses identified three primary contamination. Pb originated from nearby industrial activities their associated wastewater, suggesting that source source. Zn stem cement columns utilized oyster farming, alongside discharges mariculture pig establishing a secondary agricultural Hg ship exhaust burning oil vehicle emissions vicinity, representing third traffic (3) results demonstrated industrial, agricultural, contributing 47.19 %, 33.13 13.03 respectively, 6.65 % attributed unidentified sources.

İzmir, Turkey's third most populous city, is in an important position terms of both agriculture and industry. The province, which contributes 9.3% to the country's industrial production, also has potential olive cultivation. However, until now, no research been undertaken analyze content trace elements (TEs) soil orchards İzmir. This study was carried out determine pollution level ecological risks TEs soils İzmir reveal their sources evaluate health risks. Among TEs, average only Ni (37.9 mg/kg) exceeded world (29 mg/kg), while Cd (0.176 upper continental crust (0.09 mg/kg). Enrichment factor revealed that there significant enrichment for 73.6%, 11.6% Cr 5.4% orchards, respectively, due polluted irrigation water agrochemicals. Similarly, risk indicated were moderate considerable 48.8% 23.3% respectively. Absolute principal component scores-multiple linear regression (APCS-MLR) model showed area are affected by agricultural sources, Al, Co, Cu, Fe, Mn, Pb Zn originate from lithogenic originates mixed sources. Based on evaluation methods, non-carcinogenic carcinogenic effects would not be expected residents. provides knowledge evaluating TE serves a source apportionment human other regions.

Source apportionment and risk assessment are critical for making effective pollution prevention control policies. The study was carried out to assess source-specific ecological human health risks associated with heavy metals in farmland soils Yingtan City based on results of receptor models. Multivariate analysis the APCS-MLR model consistently revealed that As, Ni, Cr agricultural may be mainly derived from natural sources, while contents Cu, Zn, Cd, Pb have been significantly elevated by activities. According outputs model, Cu (34.3%), Zn (67.2%), (75.1%), Cd (67.9%) primarily originated industrial activities related mineral mining non-ferrous metal smelting processes. indicated sources were primary contributor total risks, posing moderate high southern mountainous regions. Natural origins played a significant role due substantial amounts As naturally occurring soils. findings could guide development management measures
