A review on marine plastisphere: biodiversity, formation, and role in degradation

Computational and Structural Biotechnology Journal, Journal Year: 2022, Volume and Issue: 20, P. 975 - 988

Published: Jan. 1, 2022

The pollution of plastic waste has become an increasingly serious environmental crisis. Recently, been detected in various kinds environments, even human tissues, which is increasing threat to the ecosystems and humans. In ocean, eventually fragmentized into microplastics (MPs) under disruption physical chemical processes. MPs are colonized by microbial communities such as fungi, diatoms, bacteria, form biofilms on surface called "plastisphere". this review, we summarize studies related microorganisms plastisphere recent years describe species plastisphere, mainly including autotrophs. Secondly, explore interactions between plastisphere. depth ocean nutrients surrounding seawater can have a great impact community structure Finally, discuss types MP-degrading bacteria use "seed bank" theory speculate potential sources microorganisms. Challenges future research prospects also discussed.

Plastisphere community assemblage of aquatic environment: plastic-microbe interaction, role in degradation and characterization technologies

Environmental Microbiome, Journal Year: 2022, Volume and Issue: 17(1)

Published: June 24, 2022

Abstract It is undeniable that plastics are ubiquitous and a threat to global ecosystems. Plastic waste transformed into microplastics (MPs) through physical chemical disruption processes within the aquatic environment. MPs detected in almost every environment due their worldwide transportability ocean currents or wind, which allows them reach even most remote regions of our planet. colonized by biofilm-forming microbial communities known as ‘‘plastisphere”. The revelation this unique substrate can aid dispersal has piqued interest ground ecology. have synergetic effects on development, transportation, persistence, ecology microorganisms. This review summarizes studies plastisphere recent years community assemblage (viz . autotrophs, heterotrophs, predators, pathogens). We also discussed plastic-microbe interactions potential sources plastic degrading Finally, it focuses current technologies used characterize those inhabitants recommendations for further research.

Interaction and combined toxicity of microplastics and per- and polyfluoroalkyl substances in aquatic environment

Frontiers of Environmental Science & Engineering, Journal Year: 2022, Volume and Issue: 16(10)

Published: April 26, 2022

Abstract Microplastics (MPs) are recognized as vectors for the transport of organic contaminants in aquatic environments addition to their own adverse effects on organisms. Per- and polyfluoroalkyl substances (PFASs) widely present due widespread applications, thus coexist with MPs. Therefore, we focus interaction MPs PFASs related combined toxicity this work. The adsorption is critically reviewed, new mechanisms such halogen bonding, π-π interaction, cation-π interactions, micelle formation proposed. Moreover, effect transformation discussed. Based four typical organisms (shellfish, Daphnia, algae, fish), and/or at organismal or molecular levels also evaluated summarized. Finally, challenges research perspectives proposed, roles shapes aging process PFAS biogeochemical processes toxicity, especially substitutes, recommended further investigation. This review provides a better understanding interactions toxic coexisting environments.

Widespread occurrence of microplastics in marine bays with diverse drivers and environmental risk

Environment International, Journal Year: 2022, Volume and Issue: 168, P. 107483 - 107483

Published: Aug. 18, 2022

Microplastic contamination in the sediment of marine bays has attracted widespread attention, whereas distribution, sedimentation, morphology and risk microplastics at regional scale remain poorly understood. By introducing a data mining framework into microplastic research, we compiled dataset 649 samples from 24 to enhance understanding geographical difference drivers, transfer, composition profile environmental sedimental microplastics. abundance varied 0.72 1963.96 items/kg dry weight, with higher concentrations mainly occurring East Asian bays. The spatial pattern was driven by river plastic emissions, aquaculture production hydrodynamic condition. A significantly positive correlation between water found, sedimentation related polymer density, conditions properties. dominant shape were fiber polypropylene, respectively, similarity decreased increasing distance. risks partitioned three classes (Rank II-Rank IV) two-dimensional assessment system considering bioavailability toxicity microplastics, identified as potential high-risk areas. To reduce bays, priority should be given removal microfibers, control measures depend on polymers. affected methodological choices regarding sampling, pretreatment identification, suggesting unified methodology is essential further our knowledge distribution

A Novel Strategy to Directly Quantify Polyethylene Microplastics in PM_2.5 Based on Pyrolysis-Gas Chromatography–Tandem Mass Spectrometry

Analytical Chemistry, Journal Year: 2023, Volume and Issue: 95(7), P. 3556 - 3562

Published: Feb. 9, 2023

The broad application of plastic products has resulted in a considerable release microplastics (MPs) into the ecosystem. While MPs other environmental matrices (e.g., soil and water) have been studied for long time, atmospheric fine particulate matter (PM2.5)-bound are rarely investigated due to lack an appropriate analytical approach. prevalently used visual spectroscopic means optical microscopy, Fourier-transform infrared spectroscopy, Raman spectroscopy) suffer from obvious drawbacks that cannot precisely detect tiny sizes provide quantitative information. In present study, novel strategy does not require sample pretreatment was developed first effectuate accurate quantification polyethylene MP (PE-MP) PM2.5 based on pyrolysis-gas chromatography-tandem mass spectrometry (Pyr-GC-MS/MS). It featured acceptable recoveries (97%-110%), high sensitivity (LOD = 1 pg), qualified precisions (RSD 3%-13%). Employing this approach, exact concentrations PE-MPs megacities North (Zhengzhou Taiyuan) South (Guangzhou) China were obtained, relatively serious pollution found Taiyuan. 100% detection rates also suggested widespread occurrence possible human exposure risks PM2.5-bound PE-MPs. brief, new could conduct direct, sensitive, PE-MP PM2.5, favoring further studies fates, distributions, toxicities MPs.
