Adsorption of pollutants on microplastics
Original title: 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.
Ogromne količine plastike i mikroplastike se svakodnevno proizvedu diljem svijeta te je količina mikroplastike u okolišu u konstantom porastu. Kada se ona nađe u vodenom okolišu organizmi je često znaju zamijeniti s hranom ili je slučajno progutati i tako se ona akumulira preko hranidbenog lanca te u konačnici dolazi do ljudi ingestijom morskih plodova i riba. Dodatan problem predstavljaju onečišćujuće tvari, poput farmaceutika i pesticida, koje se mogu adsorbirati na sitne čestice mikroplastike i tako se prenositi kroz čitav ekosustav. Kada mikroplastika s adsorbiranim tvarima završi u organizmu, adsorbirane tvari se tamo mogu desorbirati i dalje prouzrokovati štetu po organizmu. Brojna istraživanja pokazuju da takav kombinirani učinak adsorbiranih tvari i mikroplastike može predstavljati velik rizik na cjelokupne sustave. U ovom radu dati će se literaturni pregled dosadašnjih istraživanja vezanih uz adsorpciju ksenobiotika na mikroplastiku te utjecaj različitih parametara poput veličine i vrste mikroplastike, temperature, pH-vrijednosti, ionske jakosti i starenja plastike na adsorpciju ksenobiotika. Naposljetku, dati će se pregled vezan uz zajednički učinak adsorbiranih tvari (ksenobiotika) i mikroplastike na organizme.

This paper reviews how microplastics act as effective adsorbents for toxic substances including persistent organic pollutants, heavy metals, and pharmaceuticals in freshwater, marine, and urban environments. The ability of microplastics to concentrate and transport hazardous chemicals amplifies their potential harm to ecosystems and human health.
The bioaccumulation effects of microplastics and associated organic pollutants in the aquatic environment

This review examined how microplastics in aquatic environments interact with organic pollutants through adsorption, affecting the bioaccumulation and toxicity of those pollutants in aquatic organisms due to the high hydrophobicity of microplastic surfaces.
Partitioning of chemical contaminants to microplastics: Sorption mechanisms, environmental distribution and effects on toxicity and bioaccumulation
AI summary Read the abstract
This review critically examines how chemical contaminants like persistent organic pollutants and heavy metals sorb onto microplastic surfaces in the environment. Researchers found that while microplastics can concentrate pollutants at levels far above surrounding water, the actual contribution of microplastics to contaminant transfer into organisms may be less significant than direct exposure from water and food. The study calls for more realistic experimental designs to clarify the true risk.
