A Critical Review on the Impacts of Nanoplastics and Microplastics on Aquatic and Terrestrial Photosynthetic Organisms

Small, Journal Year: 2021, Volume and Issue: 17(20)

Published: April 2, 2021

Abstract Microplastic and nanoplastic contamination is widespread affects aquatic terrestrial ecosystems. Photosynthetic organisms are present in both media, they primary producers, sink for CO 2 , represent a major point of entry the food chain. Here, current knowledge on fate impacts microplastics nanoplastics interaction with these reviewed. As general trend, plastic characteristics (smaller size positive charge) play crucial role their toxicity toward photosynthetic organisms. Plastic leachates (containing additives) also source toxicity, some harmful compounds such as phthalate esters shown to accumulate plants generate risk consumers. Adsorption particles evidenced each type organism, uptake translocation nanoplastics, leading concerns trophic chain contamination. The available techniques detection secondary products biological samples media listed. Finally, gaps knowledge, specific challenges, future research directions discussed.

Plastic Waste Degradation in Landfill Conditions: The Problem with Microplastics, and Their Direct and Indirect Environmental Effects

International Journal of Environmental Research and Public Health, Journal Year: 2022, Volume and Issue: 19(20), P. 13223 - 13223

As landfilling is a common method for utilizing plastic waste at its end-of-life, it important to present knowledge about the environmental and technical complications encountered during disposal, formation spread of microplastics (MPs) from landfills, better understand direct indirect effects MPs on pollution. Plastic around active former landfills remains source MPs. The landfill output consists leachate gases created by combined biological, chemical, physical processes. Thus, small particles and/or fibers, including MPs, are transported surroundings air leachate. In this study, special focus was given potential migration release toxic substances as aging debris leads harmful volatile organic compounds via oxidative photodegradation. generally seen key vehicles accumulators non-biodegradable pollutants. Because their size, quickly over long distances throughout surroundings. With large specific surface areas, they have ability absorb pollutants, monomers additives can be leached out MPs; thus, act both vectors carriers pollutants in environment.

Plasticizer Degradation by Marine Bacterial Isolates: A Proteogenomic and Metabolomic Characterization

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(4), P. 2244 - 2256

Many commercial plasticizers are toxic endocrine-disrupting chemicals that added to plastics during manufacturing and may leach out once they reach the environment. Traditional phthalic acid ester (PAEs), such as dibutyl phthalate (DBP) bis(2-ethyl hexyl) (DEHP), now increasingly being replaced with more environmentally friendly alternatives, acetyl tributyl citrate (ATBC). While metabolic pathways for PAE degradation have been established in terrestrial environment, our knowledge, mechanisms ATBC biodegradation not identified previously plasticizer marine environment remains underexplored. From plastic debris, we enriched isolated microbes able grow using a range of and, first time, used by two phylogenetically distinct bacteria degrade three different (i.e., DBP, DEHP, ATBC) via comprehensive proteogenomic metabolomic approach. This integrated multi-OMIC study also revealed side-chain removal from (esterases enzymes involved β-oxidation pathway) well molecular response deal intermediates, is, phthalate, lower biodegrading potential detected than plasticizers. highlights exists biofilms colonize plastics-the Plastisphere-to effectively biodegrade additives flags inherent importance reducing toxicity
