Abstract

Atrazin je herbicid iz skupine koja inhibira proces fotosinteze te ometa i ostale fiziološke procese u biljci. Triazini su desetljećima bili najkorištenija skupina herbicida širom svijeta koja se koristila u poljoprivredne svrhe, ali i pri suzbijanju korova na željeznicama i urbanim područjima. Zbog takve dugotrajne, česte i raznolike upotrebe pojavila se rezistentnost korova te ogromno zagađenje okoliša, pogotovo podzemnih i površinskih voda. Također, dovela se u pitanje sigurnost živih organizama koji žive u zagađenim medijima kao i sigurnost ljudi. Iz navedenih razloga je u većini država EU zabranjena njihova primjena 2003. godine, a toj odluci su prethodila mnoga istraživanja samih herbicida te skupine kao i istraživanja njihovih metabolita. Cilj ovoga rada je prikazati medije u kojima se pronalaze rezidue atrazina, negativne utjecaje herbicida i rezidua na okoliš te organizme, utvrditi metabolite razgradnje herbicida kao i metode kojima se iste mogu dokazati.

Abstract (english)

Atrazine is a herbicide from the group that inhibits the process of photosynthesis and interferes with other physiological processes in the plant. For decades, triazines were the most widely used group of herbicides worldwide, used for agricultural purposes, but also for controlling weeds on railways and urban areas. Due to such long-term, frequent and varied use, weed resistance and enormous pollution of the environment, especially underground and surface water, appeared. Also, the safety of living organisms living in polluted media, as well as the safety of people, was called into question. For the above reasons, their use is prohibited in most EU countries in 2003 and this decision was preceded by many researches on the herbicides of this group as well as researchers on their metabolites. The aim of this paper is to show the media in which atrazine residues are found, the negative effects of herbicides and residues on the environment and organisms, to determine the metabolites of herbicide decomposition, as well as the methods by which they can be proven.
