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.

Human activities have caused different degrees of land-use change on topographic gradients, with impacts the landscape and ecosystem. Effectively preventing addressing ecological risk (ER) achieving harmonious coexistence between humans nature are important aspects sustainable development. In this study, we used Gansu Province as an example, adopted five periods data in 1980, 1990, 2000, 2010 2020, geoinformatic Tupu method terrain distribution index to study changes under then constructed assessment (LERA) model based pattern analyze (LER) spatiotemporal finally explored LER driving factors using geodetector model. The results showed that (1) dominant types were unused land grassland, accounting for approximately 74% land. situation transferring changing each type was more drastic. cropland built-up easily found low gradient areas elevations small slopes; woodland, grassland water high large slopes. (2) (LERI) 0.018, 0.019, 0.019 0.020, respectively, spatial expressions northwest southeast. Low concentrated reserves; human interference natural environmental complex areas. (3) Natural mainly acted moderate position gradients; socioeconomic gradients. interacted than alone LER. This can provide a scientific basis ensuring security development topography geomorphology.
