Once in the ocean, plastics are rapidly colonized by complex microbial communities. Factors affecting development and composition of these communities still poorly understood. Additionally, whether there plastic-type specific developing on different remains enigmatic. We determined succession bacterial under ambient dim light conditions coastal Northern Adriatic over course two months using scanning electron microscopy 16S rRNA gene analyses. Plastics used were low- high-density polyethylene (LDPE HDPE, respectively), polypropylene (PP) polyvinyl chloride with typical additives (PVC DEHP PVC DINP). The clustered groups; one group was found other all glass, which as an inert control. Specific taxa surfaces essentially stages biofilm both conditions. Differences community between exposures stronger after incubation period week than at later incubation. Under conditions, part common plastic types, especially development, families such Flavobacteriaceae, Rhodobacteraceae, Planctomycetaceae Phyllobacteriaceae presenting relatively high relative abundances surfaces. Another specific. fraction variable among types more abundant succession.

Physisorption and Chemisorption Mechanisms Influencing Micro (Nano) Plastics-Organic Chemical Contaminants Interactions: A Review

Frontiers in Environmental Science, Journal Year: 2021, Volume and Issue: 9

Published: May 28, 2021

Microplastics, which serve as sources and vector transport of organic contaminants in both terrestrial marine environments, are emerging micropollutants increasing concerns due to their potential harmful impacts on the environment, biota human health. Microplastic particles have a higher affinity for hydrophobic high surface area-to-volume ratio, particularly aqueous conditions. However, recent findings shown that concentrations adsorbed microplastic surfaces, well fate through distribution ecological risks, largely influenced by prevailing environmental factors physicochemical properties aquatic environment. Therefore, this review article draws scientific literature discuss inherent polymers typically used plastics different contaminants, compositions, factors, polymeric influence variability sorption capacities. Some specific points discussed (a) an appraisal types, composition environment; (b) critical assessment mechanisms major influencing contaminants-micro (nano) (MNPs) interactions; (c) evaluation capacities chemical MNPs terms characteristics including hydrophobicity, Van der Waals forces, π–π bond, electrostatic, hydrogen bond (d) overview dynamics behind microplastics-organic interactions using kinetic isothermal models. Furthermore, insights into future areas research gaps been highlighted.

The amount of plastic waste and microplastics released into marine environments has increased rapidly in recent decades. durability materials results major problems following their release the environment. This study provides an overview findings on issues related to degradation, accumulation mussels fishes, toxicological effects associated with ingestion microplastics. These confirm serious problem slowly degrading plastics (which rarely degrade fully) natural environments. Microplastics have become widespread pollutants been detected fish around world. Microplastic particles, whether virgin or adsorbed surfaces, pose a health after being ingested by organisms. paper ends highlighting need for certain improvements studies these phenomena.

Organotin Release from Polyvinyl Chloride Microplastics and Concurrent Photodegradation in Water: Impacts from Salinity, Dissolved Organic Matter, and Light Exposure

Environmental Science & Technology, Journal Year: 2019, Volume and Issue: 53(18), P. 10741 - 10752

Published: Aug. 12, 2019

Photochemical weathering leads to degradation of microplastics and releases chemical additives, polymeric fragments, and/or byproducts. This study evaluated the release kinetics organotin compounds (OTCs) from three different sized (10-300 μm) polyvinyl chloride (PVC) under UV- visible light irradiation. Four OTCs, dimethyltin (DMT), monomethyltin (MMT), dibutyltin (DBT), monobutyltin (MBT), were found PVC particles after 24 h leaching in darkness ranging 2 20 μg·g-PVC-1. Under UV/visible irradiation, only DMT DBT detectable, whereas MMT MBT not detected due rapid photodegradation. The total tin concentrations (including organic inorganic tins) aqueous phase monotonically increased exposure. By contrast, they reached plateaus darkness, confirming photodegradation OTCs. A model was established correctly interpreted size effect on OTC process. Finally, impacts salinity dissolved matter (DOM) investigated. OTCs both inhibited at high conditions, probably enhanced readsorption formation halogen radicals that less reactive toward neutral presence DOM, however, because excited state triplet DOM (3DOM*) formed reacted with microplastics.
