Abstract
It is not so easy to predict the toxicity of metals such as copper (Cu) and zinc (Zn) in the soil, due to the high number of factors which can affect their toxic effects. However, it can be said, that these effects constantly grows with increasing metals contents in soils, which is a common consequence of growing anthropogenic contamination. Nowadays, for the sake of minimization of the present contamination (eventual remediation of contaminated areas) and prevention of any possible contamination in the future, many countries across the World sated some regulations which limit even the contents of essential elements such as Cu and Zn. In their regulations, they incorporated the results of those topical scientific knowledge and methodologies which provide the most accurate insight into the effects of different metal concentrations on different living organisms in the circumstances of different soil conditions. In this paper, a survey of maximum allowable concentrations (MAC) in the domestic and foreign legislative is given, as well as the list of the main parameters which can affect the toxicity of metals in soils.Toksičnost metala kao što su bakar (Cu) i cink (Zn) prisutnih u zemljištu, nije lako prevideti zbog velikog broja faktora koji utiču na ispoljavanje njihovih toksičnih efekata. Ipak, može se reći da se ovi efekti sve više uvećavaju sa povećanjem sadržaja ovih metala u zemljištima koje pre svega nastaje kao posledica sve izraženijih zagađenja antropogenog porekla. Kako bi se umanjili efekti već nastalih zagađenja (eventualna remedijacija zagađenih terena), ali i prevenirale moguće buduće kontaminacije, mnoge zemlje širom sveta danas uvode propise koji ograničavaju sadržaj čak i esencijalnih elemenata Cu i Zn, ugrađujući u svoja zakonodavstva pre svega one rezultate najnovijih naučnih saznanja i metodologija koji obezbeđuju što tačniji uvid u delovanje različitih koncentracija metala na različite žive organizme i to u različitim zemljišnim uslovima. U ovom radu je dat ne samo pregled podataka za maksimalno dozvoljene koncentracije (MAK) u domaćoj i stranoj legislativi, već su navedeni i objašnjeni svi glavni parametri koji mogu da utiču na stepen ispoljavanja toksičnosti metala u zemljištima.
