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.

Road dust carries various contaminants and causes urban non-point source pollution in waterbodies through runoff. samples were collected each month two years then sieved into five particle size fractions. The concentrations of ten heavy metals (As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Zn, Fe) fraction measured. load index, coefficient divergence, Nemerow integrated risk index used to analyze the temporal variation ecological different advanced three-way model wavelet analysis quantitative identification time-series sources. Results showed that both most a decreasing trend from finest (P1) coarsest (P5). frequency P1 posing extreme was about times P5. Main types metal sources similar among fractions, whereas impact intensity these varied Traffic exhaust tended accumulate finer particles, its contribution Cu P5 only 35-55% other Construction contributed more coarser Pb increased 45.34% 65.35% Wavelet indicated traffic periodicities 5-8 10-13 months. Fuel combustion displayed strongest periodicity 12-15 months, peaking winter.

Tailings resulting from mining and smelting activities may cause soil heavy-metal pollution harm human health. To evaluate the environmental impact of heavy metals tailings on farmland soils in surrounding area, (As, Cd, Cr, Cu, Ni, Pb, Zn) vicinity a typical copper pond were analyzed. Contamination status, potential sources, health risks for investigated. The results showed that contained high concentration Cu (1136.23 mg/kg). concentrations Cd exceeded quality standard. geoaccumulation index (Igeo) indicated moderately polluted by slightly Zn. absolute principal component scores-multiple linear regression (APCS-MLR) model was applied source apportionment. release is main heavy-metals contamination, accounting 35.81%, followed agricultural (19.41%) traffic emission (16.31%). risk assessment suggested children study region exposed to non-carcinogenic caused As, while adults carcinogenic both at acceptable levels. It necessary take effective measures control contamination releases protect humans, especially children, adverse risks.

Excessive accumulation of heavy metals (HMs) in sediments poses significant threats to the aquatic ecosystems. This study comprehensively determined spatial distribution, sources, and ecological risks eight HMs 85 surface lower reach estuary Yangtze River (YR), third longest river world. Our results revealed that mean concentrations As, Cd, Cr, Cu, Hg, Ni, Pb, Zn were 11.32, 0.57, 87.31, 37.39, 0.10, 34.97, 32.27, 108.38 mg kg −1, respectively. The contamination assessment Cd Hg significantly higher than other HMs. had a variation, with concentration riverine estuarine sediments. source apportionment anthropogenic activities highest contribution occurrence (78.53%), including industrial activities, shipping transportation, agricultural production. area risk because its dense industrialization. Besides, large diffusion into ocean also substantially reduced Altogether, our findings provide better understanding causes sediment HM contamination. Hence, this work can be used as guide help government efficiently prevent control similar areas.
