To elucidate the structure of potentially pathogenic bacterial communities and their spatio-temporal patterns, a two-year study examined four contrasting land-use/land-cover types (urban, industrial, agricultural, natural forest) in a hypereutrophic urban river network of eastern China. Three predominant potentially pathogenic species appeared in both the particle-attached (PA) and free-living (FL) bacterial communities: Flavobacterium succinicans, Arcobacter cryaerophilus, and Aeromonas hydrophila. The richness, relative abundances, community complexity and stability of potentially pathogenic bacteria were generally higher in the PA fraction than those in the FL fraction. Moreover, higher concentrations of suspended particles appeared to increase the similarity in potentially pathogenic bacterial community composition between PA and FL assemblages. Redundancy analysis demonstrated that water temperature was the most influential water quality variable shaping the seasonal changes of potentially pathogenic bacterial community. The relative abundance of potentially pathogenic bacterial species in the urban river environment showed marked changes related to seasons, with its relative abundance appreciably higher in the winter dry season (January). Although the assembly mechanisms of potentially pathogenic bacterial communities were more stochastic than deterministic, those in the river surrounded by agricultural land were more deterministic compared to with other land-use/land-cover types. Potentially pathogenic bacterial communities with a high proportion of positive correlations might have weak stability.

MPs were measured in sediment, water, and tissues (intestines and gills), while oxidative stress and detoxification biomarkers (CAT, SOD, GSH, GSSG, GST), along with MDA (lipid peroxidation indicator) and PCC (protein oxidation indicator), were analysed across three zones (internal, middle, and external) with different invasion levels.

Despite extensive regional Pb pollution investigations, the long-term global spatiotemporal evolution and health impacts of particle-bound Pb during 2000-2019 remain insufficiently clarified. Here, we constructed a refined global Pb emission inventory and adopted the GEOS-Chem model to comprehensively simulate global Pb spatiotemporal variations across eight typical regions for the first time, followed by a quantitative assessment of Pb-related carcinogenic and non-carcinogenic health risks for adults and children. The correlation of simulations and observations reaches 0.82, indicating the robust modelling results. The results exhibited profoundly uneven global Pb distributions, with China dominating the highest pollution levels (15.3 ± 11.7 ng/m³), while developed and low-industrialized regions maintained relatively low concentrations. Distinct hemispheric seasonal discrepancies were identified: Northern Hemisphere regions peaked in boreal winter due to heating emissions and stable boundary layer trapping, whereas Southern Hemisphere Pb maxima occurred in austral autumn derived from biomass burning. A universal global Pb turning point emerged in 2013, with concentrations rising during 2000-2013 and declining afterward. Strict emission controls reversed China's growing Pb pollution, while continuous increases prevailed in India, Sub-Sahara Africa (SSA) and South America (SA), revealing a clear pollution shift from developed to emerging industrial regions.

In cities, air pollution mitigation depends on curbing emissions and fostering ecosystem services, particularly through tree planting. Whereas the role of urban trees in air pollution mitigation is well established, trees' responses to reduced air pollution stress remain poorly quantified. Air pollution can limit trees' benefits by constraining stomatal conductance, photosynthesis, and xylogenesis. This study assessed the impacts of acute air pollution reduction during the COVID-19 lockdowns on Tipuana tipu trees growing in a park and on a main avenue in São Paulo, Brazil. To test whether air pollution-driven physiological and structural limitations were reduced during the lockdowns, we assessed high-resolution tree-ring stable carbon isotope composition (δ¹³C) and wood density (WD) across 15 evenly-spaced intra-annual segments from 2018 to 2021. Avenue trees exhibited lower δ¹³C values than park trees, indicating greater exposure to fossil-fuel CO₂ emissions, and the higher WD was consistent with water stress. The most restrictive lockdown (based on pollution and CO₂ concentration data) at the end of the 2020/2021 growing season coincided with a shift in the typical decreasing intra-annual δ¹³C trend in the avenue trees to an increasing trend at the end of the tree ring, a pattern not observed in the park trees. This increasing shift was not readily explained by improved weather conditions or leaf-physiology responses. Instead, the δ¹³C fractionation model simulations suggest a strong source signal, reflecting an increase in the atmospheric δ¹³C signature during the lockdown, more so than the reduction in CO₂ concentration. Although the intra-annual WD trends remained consistent, increasing from earlywood to latewood, avenue trees displayed a steeper increase in WD across the 2020/2021 tree ring, possibly associated with increased stomatal conductance.
