Abstract

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.

Abstract (english)

Environmental pollution is caused by people who create, accumulate and improperly dispose solid, liquid and gaseous waste. The appearance of the environment therefore changes. All environmental pollutants have an impact on flora and fauna, and directly and indirectly on humans. Ubiquitous environmental pollutants are various plastic residues, mostly non-degradable material, which enter into various physico-chemical interactions with other toxic substances and cause the ecological crisis of today. The group of toxic substances includes heavy metals, pesticides, pharmaceuticals, various additives used in the food and cosmetics industry and waste gas emissions over large cities and industrial zones. Today, in the ecological crisis which society has to face, the ability of Earth to maintain developed life forms is questionable. This work presents an overview of the summarized effects of environmental factors on the properties and adsorption characteristics of micro and nanoplastics. Pharmaceuticals and heavy metals represents a group of pollutants that can be adsorbed on micro and nanoplastics particles. Such tiny particles of micro and nanoplastics enter the food chain of various organisms, which is a major global problem that is increasingly being explored. It is important to estimate the potential risks that microplastics pose to organisms from human beings to the entire environment.
