The interaction between antibiotics and antibiotic resistance genes (ARGs) in freshwater ecosystems has become a critical environmental concern. This study investigates seasonal variations of sulfonamide tetracycline their relationship with ARGs three urban reservoirs Nanjing, China: Pingshan Forest Park, Shanhu Lake Wetland Zhaoqiao Reservoir. Sampling was conducted May September 2023 to assess water quality, concentrations, ARG abundance. A total 30 samples were analyzed regard physicochemical parameters, heavy metals, antibiotics. quantitative PCR assay used measure the abundance relative 16S rRNA gene. Sulfonamide concentrations ranged from 120 ng/L, while tetracyclines 50–160 ng/L. Notably, sulfamethazine decreased significantly two (Shanhu Zhaoqiao, p < 0.05), other showed minimal variation, indicating persistent contamination agricultural runoff wastewater discharge. lower than September, being cumulatively genes. Strong correlations (r > 0.7) observed parameters like dissolved oxygen pH. High levels areas without nearby hospitals or pharmaceutical companies, implicating agriculture as major pollution source. By analyzing across eutrophic China, we highlight drivers proliferation propose targeted mitigation strategies.

The molecular insights of cyanobacterial bioremediations of heavy metals: the current and the future challenges

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Опубликована: Окт. 11, 2024

In recent years, overexplorations of ore and the growth industries are prime factors in release heavy metals environments. As a result, food crops water bodies contaminated with which may have several adverse effects on health humans other living species. These metalloids, such as Zn, Cu, Mn, Ni, Cr, Pb, Cd, As, upset biochemical pathways metabolite synthesis organisms contribute to etiology different diseases. Microorganisms include bacteria, archaea, viruses, many unicellular eukaryotes, can span three domains life—Archaea, Bacteria, Eukarya—and some microorganisms, cyanobacteria, shown high efficiency biosorption rate metals. Cyanobacteria suitable for bioremediation they grow environments, less negative impact surrounding environment, relatively cheaper manage. The structure cyanobacteria has no extensive internal-bound membranes, so it directly employ physiological mechanisms uptake from contamination sites. Such makeups managing bioremediating metal concentrations polluted This review aims explore potential metalloids bodies. Additionally, we identified prospects enhancing effectiveness.

Cyperus esculentus var. sativus Adapts to Multiple Heavy Metal Stresses Through the Assembly of Endophytic Microbial Communities

Biology, Год журнала: 2025, Номер 14(1), С. 83 - 83

Опубликована: Янв. 16, 2025

Interactions between plants and their endophytes alter metabolic functions ability to cope with abiotic stresses. In this study, high-throughput sequencing was used analyze the species diversity of in Cyperus esculentus var. sativus (CES) tubers under different heavy metal stress conditions. The results indicated that number observed endophytic increased (p < 0.05), leading changes composition. response tuber concentrations varied, certain bacteria fungi, such as Pseudomonas, Novosphingobium, Fusarium, showing abundance becoming dominant tubers. Additionally, new genera, Actinophytocola Monosporascus, emerged at specific 0.05). Fatty acid salvage enriched CES, which may play an important role assisting CES responding multiple These findings showed undergo adaptive support stress.

Mineral Composition and Elemental Oxide Changes in Heat-Affected Soils and the Implications on Heavy Metal Immobilization by Sewage Sludge

Minerals, Год журнала: 2025, Номер 15(2), С. 143 - 143

Опубликована: Янв. 31, 2025

This paper investigated how increased soil temperatures affect mineralogy and major trace element oxide concentrations the implications of these effects on mobility potentially toxic elements (PTEs) in heat-affected soils amended with sewage sludge. The aim was to determine efficiency sludge as an immobilizer PTEs PTE-contaminated soils. Soil samples were heated 150 °C, 300 500 750 °C later stabilized at different rates. arsenic (As), chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), nickel (Ni), zinc (Zn) geochemical fractions determined before heating, after application. Increased affected mineral assemblage some oxides degree weathering These changes were, however, insignificant. segregation into heating varied. High resulted increase PTE non-residual (F1, F2, F3) a consequent their mobility. application unheated reduced F1 F2 both soils, whereas it F3 F4 by up 30% for As Cu, 20% Cd, 25% Co, 60% Cr Ni, 50% Pb, 55% Zn. Significant immobilization observed that received higher amount Fire events could but still effectively immobilize PTEs, although needs be applied

Опубликована: Апрель 18, 2025

Heavy metal contamination in marine ecosystems poses a critical environmental challenge, with significant implications for biodiversity, trophic dynamics, and human health. Marine fish are key bioindicators of heavy pollution because their role food webs capacity bioaccumulation transfer. This review synthesizes current knowledge on the pathways mechanisms accumulation fish, focusing factors that influence uptake, retention, tissue distribution. We explore processes governing transfer biomagnification, highlighting species-specific patterns risks posed to apex predators, including humans. Additionally, we assess ecological consequences at population, community, ecosystem levels, emphasizing its effects reproduction, community structure, interactions. By integrating recent findings, this highlights gaps suggests future research directions improve monitoring risk assessment. Given persistence bioavailability metals environments, effective control strategies sustainable fisheries management imperative mitigate long-term public health risks.
