Study of Selected Physicochemical Characteristics and Content of Macro– And Microelements in the Lake Gruža Water

Abstract

Water is one of the most precious natural resources. The downtrend in the quality of lake water and pollution with heavy metals cause serious threats to the environment in last decades. Particularly vulnerable are the lakes that are located near towns and villages. The aim of this study was to investigate the physicochemical parameters and levels of macro– and microelements in order to determine the water quality of Lake Gruža in the summer period. The results showed that the studied parameters were within the permissible levels, except of concentrations of iron, cobalt and vanadium.

Voda predstavlja jedan od najdragocenijih prirodnih resursa. Opadanje kvaliteta jezerskih voda i zagađenje teškim metalima, predstavljaju ozbiljne pretnje za životnu sredinu u poslednjih nekoliko decenija. Posebno su ugrožena jezera koja se nalaze u blizini gradova i naselja. Cilj rada bio je ispitivanje osnovnih fizičko–hemijskih parametara i sadržaja makro– i mikroelemenata kako bi se utvrdio kvalitet vode jezera Gruža u letnjem periodu. Rezultati su pokazali da su ispitivani parametri u vodi bili u okviru dozvoljenih vrednosti, osim sadržaja gvožđa, kobalta i vanadijuma.
