Adsorption of organic pollutants and metals on micro/nanoplastics in the aquatic environment
AI summary Read the abstract
This Croatian thesis reviews how microplastics and nanoplastics adsorb organic pollutants and metals in aquatic environments, acting as vectors for combined contamination. The author examines the physicochemical interactions between plastic surfaces and various environmental contaminants.
Onečišćenje okoliša uzrokuju ljudi koji stvaraju, gomilaju i nepropisno odlažu kruti, tekući i plinoviti otpad. Pri tome se mijenja izgled okoliša. Sva onečišćenja okoliša imaju utjecaj na floru i faunu, a posredno i neposredno na čovjeka. Sveprisutni onečišćivači okoliša su različiti plastični ostaci, većinom nerazgradivi materijali, koji stupaju u različite fizikalno – kemijske interakcije s drugim toksičnim tvarima te uzrokuju ekološku krizu današnjice. U grupu toksičnih tvari ubrajaju se teški metali, pesticidi, farmaceutici, različiti aditivi koji se koriste u prehrambenoj i kozmetičkoj industriji te emisije otpadnih plinova iznad velikih gradova i industrijskih zona. U ekološkoj krizi s kojom se današnje društvo mora suočavati upitna je sposobnost Zemlje da održi razvijene forme života. U ovom radu prikazan je pregled učinaka okolišnih čimbenika na svojstva i adsorpcijske karakteristike mikro i nanoplastike. Farmaceutici i teški metali predstavljaju grupu onečišćivača koji se mogu adsorbirati na čestice mikro i nanoplastike te istovremeno s plastikom ulaze u biogeokemijski ciklus i hranidbeni lanac raznih organizama što predstavlja veliki globalni problem koji se sve više istražuje. Od velike je važnosti procijeniti potencijalne rizike koje mikroplastika predstavlja za živu i neživu prirodu.

Adsorption of pollutants on microplastics
AI summary Read the abstract
This Croatian-language review examines how microplastics in aquatic environments adsorb chemical pollutants onto their surfaces, effectively concentrating toxins that are then ingested by marine organisms and passed up the food chain to humans. The review covers both organic and inorganic contaminants and their interactions with different plastic types.
Adsorption behavior of organic pollutants and metals on micro/nanoplastics in the aquatic environment
AI summary Read the abstract
This review examines how micro- and nanoplastics in aquatic environments adsorb organic pollutants and metals onto their surfaces, effectively acting as carriers for other contaminants. Researchers found that environmental factors like pH, salinity, and aging of the plastic significantly influence this sorption behavior. The findings raise concerns that microplastics may increase the bioavailability and toxicity of chemical pollutants in waterways.
Adsorption behaviour and interaction of organic micropollutants with nano and microplastics – A review
AI summary Read the abstract
This review analyzed the adsorption behavior of organic micropollutants — including pharmaceuticals, pesticides, and industrial chemicals — onto nano- and microplastics, finding that adsorption is governed by pollutant hydrophobicity, particle surface area, and aging state, and that microplastics can act as vectors delivering co-contaminants to aquatic organisms.
Adsorption Behavior and Interaction of Micro-Nanoplastics in Soils and Aquatic Environment
AI summary Read the abstract
This review examined how micro- and nanoplastics adsorb environmental pollutants in soil and aquatic environments, acting as vectors that transfer and enhance the bioavailability of contaminants. Aging and weathering processes that alter plastic surface properties were identified as key factors influencing adsorption capacity and pollutant interactions.
The chemical behaviors of microplastics in marine environment: A review
AI summary Read the abstract
This review summarized interactions between microplastics and organic pollutants and metals in the marine environment, covering sorption behavior across polymer types, the role of degradation in altering sorption capacity, and global monitoring data on pollutant concentrations on marine plastics. The authors conclude that microplastic type, pollutant properties, and environmental conditions all strongly influence chemical accumulation on plastic surfaces.
