Lake sediments serve as a sink for trace elements and provide record of watershed changes resulting from anthropogenic activities natural processes. In this study, eight in the Aha, an urban lake Guiyang City, Southwest China, were investigated to reveal effects historical coal mining rapid urbanization watershed. Results showed that median contents measured order Zn (220.00 mg/kg) > Ni (98.16 Cr (70.26 Cu (66.20 As (58.14 Co (41.66 Pb (28.33 Cd (1.39 mg/kg). Except Pb, concentrations Cd, As, Zn, Ni, Co, 4.64, 2.33, 2.00, 1.92, 1.81, 1.09 times higher than regional background values respectively. Trace element center significantly rest sediment cores, relatively stable hydrodynamic processes region. Vertical variation indicated fluctuations intensity tributaries effectively tracked by variations levels middle layer Youyu River Baiyan estuaries. The elevated surface Jinzhong estuary reflected basin over past 20 years. PMF analysis demonstrated mixture activities, Cu, originated mining. This study provides important information comprehending small-scale lakes environmental changes.

Heavy metal (HM) contamination of aquatic ecosystems has increasingly posed threats to ecological balance and health. Analysis sediments determine water pollution sources is widely reported, while quantitative research about the effects environmental factors on distribution HMs relevant microbial communities limited. Here, we investigated 6 kinds HM characteristics (As, Cd, Cr, Cu, Pb, Zn) Pearl River Delta (PRD) by collecting surface sediment samples around main stream estuary explored influencing with a geographical detector method (GDM). The shifts in corresponding community was further analyzed, influence mechanism clearly elucidated using partial least squares path modeling (PLS-PM). Results showed that (i) most contents greatly exceeded local background values, wherein, Cd had highest level; (ii) temperature considered dominant natural factor distribution, except for an degree 0.68–0.97; (iii) industrial activity significant anthropogenic electroplating industry source Cu Zn; (iv) network analysis revealed As, Cr were enriched some HM-tolerant bacteria (mainly Chloroflexi, Acidobacteriota Proteobacteria), heavy induced reduction sensitive bacterial taxa; (v) PLS-PM demonstrated human activities largely affect causing pollution. This study could provide guidance better management control practices, such as specific governance layout optimization.

Heavy metal pollution in farmland soil represents a considerable risk to ecosystems and human health, constituting global concern. Focusing on key area for the cultivation of special agricultural products Cangxi County, we collected 228 surface samples. We analyzed concentration, spatial distribution, levels six heavy metals (Cr, Cu, Pb, Ni, Zn, Hg) soil. Moreover, investigated sources contribution rates these using Principal Component Analysis/Absolute Scores (PCA/APCS) Positive Matrix Factorization (PMF) models. Our findings indicate that none exceeded thresholds soils. However, mean concentrations Cr Ni surpassed background Sichuan Province. A moderate correlation existed between Pb attributable both natural anthropogenic factors, whereas Hg, displayed strong correlation, mainly due factors. The patterns Cr, were similar, with higher northern eastern regions lower centrally. Hg’s distribution differed, exhibiting broader range values. single index evaluation showed low pollution, other elements no pollution. average value comprehensive is 0.994, degree close light Predominantly, regions, around reservoirs. PCA/APCS model identified two main sources: traffic mixed source (65.2%) parent (17.2%). PMF delineated three activities (32.59%), transportation (30.64%), (36.77%). Comparatively, proved more accurate reliable, yielding aligned study area’s actual conditions.
