The property of being stubborn and degradation resistant makes nanoplastic (NP) pollution a long-standing remaining challenge. Here, we apply designed top-down strategy to leverage the natural hierarchical structure waste crayfish shells with exposed functional groups for efficient NP capture. shell-based organic skeleton improved flexibility, strength (14.37 60.13 MPa), toughness (24.61 278.98 MJ m–3) was prepared by purposefully removing inorganic components through simple two-step acid–alkali treatment. Due activated (e.g., -NH2, −CONH−, −OH) ordered architectures macropores nanofibers, this porous shell exhibited effective removal capability NPs (72.92 mg g–1) physical interception hydrogen bond/electrostatic interactions. Moreover, sustainability stability were demonstrated maintained high-capture performance after five cycles. Finally, provided postprocessing approach that could convert both into tough flat sheet. Thus, our feasible engineering combined promising posttreatment is powerful contender recycling broad application scenarios clear economic advantages simultaneously addressing biomass pollutants.

Abstract Previous studies reported microplastics (MPs), antibiotics, and antibiotic resistance genes (ARGs) in wastewater treatment plants (WWTPs). There is still a lack of research progress on the origin, fate, impact hazards MPs ARGs WWTPs. This paper fills gap this regard. In our search, we used “microplastics”, “antibiotic genes”, “wastewater plant” as topic terms Web Science, checking returned results for relevance by examining titles abstracts. study mainly explores following points: (1) origins fate MPs, antibiotics WWTPs; (2) mechanisms action sludge biochemical pools; (3) impacts WWTPs spread ARGs; (4) harm inflicted environment human body. Contaminants sewage such ARGs, antibiotic-resistant bacteria enter soil water. can travel through food chain thus reach humans, leading to increased illness, hospitalization, even mortality. will enhance understanding among they inflict

Microplastics in the environment can be colonized by microbes capable of forming biofilms, which may act as reactive coatings to affect bioaccessibility pollutants organisms. This study investigated dynamic evolution biofilm colonization on microplastics and its impacts mechanisms microplastic-associated sulfamethazine (SMT) via microcosm incubation surface water sediment. After 60 days incubation, microbial communities formed were distinct more diverse than those untethered surroundings, photoaging treatment decreased affinity biofilms due hydrophobicity. Biofilm formation further enhanced desorption microplastic-sorbed SMT In vitro experiments indicated that critical effects mainly related stronger interaction gastrointestinal components (i.e., pepsin, bovine serum albumin (BSA), NaT) with (e.g., extracellular polymer substances) pure microplastics, competed for binding sites significantly. Photoaging enhancing their lower accumulation aged microplastics. is first attempt reveal role associated antibiotics provide insights into combined risk environment.

Microplastics (MPs) are small plastic pieces less than 5 mm in size. Previous studies have focused on the sources, transports, and fates of MPs marine or sediment environments. However, limited attention has been given to role land as primary source MPs, how polymers transformed into through biological abiotic effects during transport process remains unclear. Here, we focus exploration main sources soil, highlighting that MP generation is not solely a byproduct production but can also result from impact factors transport. This review presents new perspective understanding degradation considering soil distinct fluid suggesting transformation change mediated by occur surface, while biodegradation occurs interior. viewpoint suggested because some becomes obvious interior, whose surface expected colonize microorganisms, gradually considered carbon independent photosynthesis net production. emphasizes need understand basic information for rational evaluation its environmental toxicity. Such enables better control pollution affected areas prevents contamination unaffected regions. Finally, knowledge gaps future research directions necessary advancements this field provided.
