Abstract Microplastics (MPs) are a class of emerging contaminants that have gained significant attention in recent years. The presence MPs the aquatic environment is reported to serious potential environmental and health impacts. Therefore, it essential develop efficient sustainable strategies for remediation from aqueous environment. Traditional techniques an limitations, including high costs production secondary pollutants. In this scenario, bioremediation offers several advantages has emerged as cost‐effective, eco‐friendly, strategy removal water. This article critically reviews progress applications different effects key factors such characteristics MPs, conditions, types microorganisms on elaborated detail. underlying mechanisms involved by also discussed comprehensively. Major technological challenges identified, recommendations future research provided. Despite challenges, promising approach can revolutionize MP process if major addressed.

Coagulation is a widely employed technique for removing suspended particles from water and wastewater, recently, it has gotten attention as popular method the removal of microplastics (MPs). Studies on coagulation-based MPs are still in their infancy, few findings available about this treatment approach, its mechanism, efficiency. Given these gaps, study was designed to comprehensively investigate recent advances via coagulation. The influence various experimental factors such coagulant type, dose coagulant, pH solution, shape critically reviewed. showed that optimizing environmental conditions during coagulation process crucial improving reducing energy costs. efficiency depends optimal reaction conditions, which may vary depending type concentration characteristics or wastewater being treated. Optimizing is, therefore, critical achieving maximum More extensive research required reveal mechanisms controlling floc density pollutants effluent. Consequently, current review aims highlight gaps challenges associated with techniques treatment. Current advancements synthesis chemical modification bio-based coagulants performance could constitute paradigm shift ecosystem protection sustainability. use eco-friendly combining other suggested increase efficacy viability method. This will provide significant insights field researchers, guiding future investigations contributing advancement knowledge.

Abstract The current study focuses on the sources and formations of microplastics (MPs) in receiving environments, addressing various analytical methods used for detection characterization MPs water wastewater, including particle size distribution analysis, FTIR, Raman, SEM‐EDS, thermo (Pyro GC‐MS, TGA‐MS, TED‐GC‐MS, TGA‐SPE/TDS‐GC‐MS) combine techniques (Tagging method, Liquid chromatography, SEM dispersive X‐ray spectrometer). fills a gap literature by evaluating advantages limitations advanced methods, addition to commonly like SEM, providing perspective other significant approaches. By examining comparing different identify detect wastewater research guides scientists making informed choices when selecting specific method. A better understanding these will inform future facilitate more effective management potential environmental impacts human health risks. This also contributes significantly preserving resources, health, establishing sustainable environment encouraging generation actionable information assess risks develop strategies reducing their presence.

Abstract The sand‐dust weather and storms have become a serious environmental disaster worldwide. It is an important challenge to develop technologies for desert sand solidification in order prevent control weather. biomineralization technology solidifying sands has been novel method reinforced soils recent years. field tests are completed at the Wuma Highway section Tengger Desert. superiority of verified by measuring water storage capacity different reinforcement zones including bare zone, plant combined zone. Simultaneously, molecular dynamics calculation analysis used verify role preventing storms. All results demonstrate that effective controlling sandstorm disasters.

Highlights•Indoor dust all around Dhaka contained a high abundance of microplastics.•Fiber's length in the range 50–250 μm were predominant.•Deposition rates microplastics varied based on different indoor factors.•Various polymers identified atmospheric Dhaka.AbstractMicroplastic (MP) contamination has become concern due to its ubiquitous presence. Recent studies have found MPs be present multiple human organs. This study was carried out evaluate presence and characterize deposition. Deposited collected from fifteen households city. The samples underwent quantification using stereomicroscopy. Fourier Transform Infrared (FTIR) spectroscopy performed understand polymer composition. size group ranging 50 250 most dominant. deposition 7.52 × 10³ MPs/m2/day 66.29 MPs/m2/day, with mean rate being 34 MPs/m2/day. Notably, number occupants height sampling location above ground level influence rates. Various polymers, including polyester (PET), polyethylene (PE), Nylon, polypropylene (PP), identified. estimated inhalation exposure 2986 ± 1035 MPs/kg-BW/day. work highlights need for additional research explore microplastic potential effect health densely inhabited severely polluted megapolis Dhaka, Bangladesh.Graphical abstract

Recent research has highlighted the potential of honeybees and bee products as biological samplers for monitoring xenobiotic pollutants. However, effectiveness these in tracking microplastics (MPs) not yet been explored. This study evaluates several methods sampling MPs, using honeybees, pollen, a novel in-hive passive sampler named APITrap. The collected samples were characterized stereomicroscopy to count categorise MPs by morphology, colour, type. To chemical identification, micro-Fourier transform-infrared (FTIR) spectroscopy was employed determine polymer types. conducted across four consecutive surveillance programmes, five different apiaries Denmark. Our findings indicated that APITrap demonstrated better reproducibility, with lower variation results 39%, compared 111% honeybee 97% pollen samples. Furthermore, use no negative impact on bees can be easily applied successive samplings. average number detected studies ranged from 39 67 APITrap, 6 9 samples, 11 Fibres most frequently found, accounting an 91% total similar values fragments (5%) films (4%). predominantly coloured black, blue, green red. Spectroscopy analysis confirmed presence up synthetic polymers. Polyethylene terephthalate (PET) common case fibres similarly polypropylene (PP), polyethylene (PE), polyacrylonitrile (PAN) polyamide (PA) non fibrous MPs. study, based citizen science supported beekeepers, highlights potencial accumulate beehives. It also shows provides highly reliable comprehensive approach large-scale studies.
