Chemical modifications of granular activated carbon (GAC) and powdered (PAC) are necessary for enhanced removal perfluoroalkyl polyfluoroalkyl substances (PFAS) in water. Herein, we synthesized tested goethite (α-FeOOH)-coated GAC PAC the adsorption mixtures 13 PFAS (9 short- long-chain PFAAs, GenX, 3 precursors) from water at an initial concentration 10 μg/L each. Among sorbents tested, modified (MPAC) had excellent compared to pristine (MGAC). Based on isotherms, maximum capacity MPAC toward total was 234 mg/g. Detailed characterizations revealed that performance due its nature, which enabled a shorter diffusion path rapid mass transfer internal pores this sorbent addition electrostatic hydrophobic interactions. Results obtained study provide valuable insights knowledge properly modifying address critical challenges associated with PFAS, especially those short-chain compounds.

Seasonal changes in N-cycling functional genes in sediments and their influencing factors in a typical eutrophic shallow lake, China

Frontiers in Microbiology, Год журнала: 2024, Номер 15

N-cycling processes mediated by microorganisms are directly linked to the eutrophication of lakes and ecosystem health. Exploring variation influencing factors N-cycling-related genes is great significance for controlling lakes. However, seasonal dynamics genomic information encoding nitrogen (N) cycling in sediments eutrophic have not yet been clearly addressed. We collected Baiyangdian (BYD) Lake four seasons explore dynamic functional based on a shotgun metagenome sequencing approach reveal their key factors. Our results showed that dissimilatory nitrate reduction (DNRA), assimilatory (ANRA), denitrification were dominant processes, abundance nirS amoC higher than other at least one order magnitude. Functional genes, such as , nirK generally consistent decreasing trend from warming season (i.e., spring, summer, fall) cold winter). Furthermore, significantly nitrification (e.g., amoB, hao ) spring nirS, norC nosZ fall observed. influenced different environmental Generally, dissolved organic carbon (DOC) or sediment matter (SOM), water temperature (T) antibiotics Norfloxacin ofloxacin) correlated with processes. The findings imply may be potentially lake ecosystems, which will provide reference management
