Heavy metal(loid) (HM) contamination in soils from smelting activities poses significant environmental and public health risks, as well disruptions microbial community dynamics HM resistance gene profiles. This study investigates the diversity, resistome, physicochemical properties of abandoned Avalos smelter Chihuahua, Mexico. Through soil analyses, we identified elevated concentrations certain HMs, which pose serious hazards. The metagenomic analysis community, composed bacteria, archaea, fungi, was dominated by genera such Streptomyces, Bradyrhizobium, Halobaculum, Nitrosocosmicus, Fusarium, Aspergillus rhizospheric soil. Furthermore, a diverse array metal genes (MRGs) were detected, associated with copper, arsenic, iron, lead, cadmium, zinc, other HMs. Additionally, metagenome-assembled genomes (MAGs) revealed presence functional linked to resistance, providing deeper insights into ecological roles metabolic capabilities taxa. These findings highlight impact smelting-derived on diversity potential, offering valuable for development bioremediation strategies HM-contaminated environments.

The application of nitrification inhibitors (NIs) is an effective way to reduce soil nitrogen (N) losses and increase crop N uptake. Yet, the efficacy NIs commonly varies with dosages, systems environmental conditions. Hence, clarifying suitable type dosage extremely important for structuring best management regime at a regional scale. Here, based on microcosm experiments, we evaluated influence three widely used [Dicyandiamide, DCD; 3,4-Dimethylpyrazole phosphate, DMPP; 2-chloro-6-(trichloromethyl) pyridine, Nitrapyrin] activity intensively cultivated greenhouse soil. results showed that both DCD DMPP imposed transient inhibition (less than five days) regardless dosages applied, and, contrary, Nitrapyrin presented persistent suppression, longer duration action by higher dosage. Accordingly, incorporation 2% applied rate (w/w) recommendable local intensive production. Further, assessed various (0%, 0.25%, 0.5%, 5%) abundance community groups ammonia oxidizers [i.e., ammonia-oxidizing archaea (AOA), bacteria (AOB) completely (Comammox Nitrospira)] qPCR high-throughput amplicon sequencing. strongly lowered AOB Comammox Nitrospira abundances their richness even lowest also significantly altered structure all tested oxidizers, average relative some major members (i.e., Nitrososphaerales Clade Nitrososphaera, A, Nitrosospira briensis Clade, multiformis A.2 A-associated) obviously responded incorporation. Overall, our findings indicated were more sensitive as compared AOA. obtained here highlight importance optimizing fertilization in vegetable inhibits probably suppressing level herein.
