Although resistance genes are a global concern in ecosystems, the underlying factors responsible for their worldwide dissemination, especially urban greenspaces, poorly known. To investigate metal and (MRGs) accumulation parks, we used ICP-MS to analyze concentrations GeoChip functional gene arrays MRGs abundances vegetation types with labile recalcitrant litter across parks non-urban reference sites three distinct climatic regions: Boreal (Finland), Temperate (Baltimore, USA), Tropical (Singapore). Our results indicate that park soils increase age zones, so dominant metals - Fe Al accounting more than 90% of total content, others, e.g., Mn, Zn, Pb. Correspondingly, were most abundant MRGs, representing 23% all detected MRGs. Vegetation type affected only boreal region, not temperate or tropical regions, suggesting context is generalizable zones. analyses also distribution weakly by soil properties, but largely associated from traffic industrial sources. data further antibiotic (ARGs) co-selected accumulation. The pattern MRG abundance between old young similar ARGs, indicating potential risk human health parks. findings emphasize importance corresponding cumulative effects anthropogenic activities as driver dynamics globally.

Heavy metals (HMs) significantly affect the anaerobic fermentation of coal slime (CS), while sawdust serves as a promising substrate for methane bioconversion and an effective adsorbent HMs. To explore migration HMs improve conversion efficiency CS to biomethane, experiments were conducted on co-fermentation with different mass ratios. FT-IR, ICP-MS, SEM-EDS, metagenomic sequencing employed elucidate regulation mechanism microorganisms after adding in altering toxicological environment. The results revealed that optimum ratio was 2:1. Oxygen-containing functional groups removed, fatty structure degraded. Addition promoted further degradation various Metal elements such Fe, Mg, Co, Cd had also been detected its surface. Bacillota (39.05%) enriched, which effectively improved microbial community structure. abundance species metal detoxification functions increased. types transporters related toxic ions increased families ATP-binding Cassette Superfamily (ABC) Resistance-Nodulation-Cell Division (RND), would aid cellular homeostasis. Moreover, addition expression resistance genes (MRGs). Multi-MRGs primarily linked Cu, As, Zn, bacterial contributing key MRGs copA, ziaA, actP. These findings offer valuable insights support clean efficient utilization sawdust.

ABSTRACT Global urbanization accelerates pollution challenges in urban rivers, including increased transmission of bacterial antibiotic resistance genes (ARGs), severely threatening the health aquatic ecosystems and human health. Yet, systematic knowledge differences distribution community assembly patterns across rivers at a continental scale is still insufficient. In this study, we conducted extensive sampling nine representative China. We used amplicon shotgun metagenomic sequencing, state‐of‐the‐art bioinformatics, multivariate statistics to investigate mechanisms planktonic microbiomes (i.e., bacterioplankton microeukaryotes), their resistomes, i.e., ARGs metal (MRGs). Geographical environmental factors played pivotal role shaping vs. resistomes studied rivers. Phylogenetic‐bin‐based null model analysis (iCAMP) indicated that microbiomes, dominated by dispersal limitation drift, tend toward spatial heterogeneity. contrast, driven deterministic processes, display more similar patterns. Cross‐validated Mantel tests revealed geographical geographic distance) were primary regulators microbial assembly, while temperature) control processes resistomes. Our findings provide crucial insights into driving biogeographical entities scale, offering valuable implications for mitigating managing spread from environment humans.
