Hydrophilic Fraction of Dissolved Organic Matter Largely Facilitated Microplastics Photoaging: Insights from Redox Properties and Reactive Oxygen Species

Environmental Science & Technology, Год журнала: 2024, Номер 58(26), С. 11625 - 11636

Опубликована: Июнь 7, 2024

Dissolved organic matter (DOM) exists widely in natural water, which inevitably influences microplastic (MP) photoaging. Nevertheless, the impacts of DOM fractions with diverse molecular structures on MP photoaging remain to be elucidated. This study explored mechanisms polylactic acid (PLA)-MPs and polystyrene (PS)-MPs presence its subfractions (hydrophobic (HPOA), hydrophobic neutral (HPON), hydrophilic (HPI)). Across fractions, HPI exhibited highest electron accepting capacity (23 μmol e

Occurrence of antibiotics and antibiotic resistance genes at various stages of different aquaculture modes surrounding Tai Lake, China

Frontiers in Microbiology, Год журнала: 2025, Номер 16

Опубликована: Янв. 31, 2025

Aquaculture is an important source of antibiotics and ARGs in environmental waters. However, the occurrence under different modes stages aquaculture has rarely been systematically studied. This paper uses qPCR, LC-MS, High-Throughput sequencing across culture to investigate antibiotics, resistance genes, microbial communities water bodies, analyze contamination differences between these modes. The quinolone chloramphenicol were main highest absolute abundance genes (qnrB) (sul1), with mobile genetic element (MGE) intI1, both which exhibited a gradual seasonal increase. Microbial diversity also varies seasonally, especially increase some pathogenic bacteria (Flavobacterium). Antibiotics found at higher levels fish ponds compared shrimp crab ponds, while they lower that utilized ecological mode than traditional ponds. Our study presents comprehensive characterization waters from various perspectives. Ecological contribute reducing antibiotic gene pollution bodies. These findings will support optimization usage green sustainable development finally.
