Abstract

Cilj ovoga rada je odrediti fizikalne, kemijske i biološke pokazatelje kakvoće vode potoka Črnec– prirodnog prijemnika II. kategorije u gornjem toku i III. kategorije u donjem toku. Dobiveni rezultati pokazatelja kakvoće vode se nakon statističke obrade uspoređuju s propisanim maksimalnim dozvoljenim koncentracijama. Na temelju toga vode se svrstavaju u određenu kategoriju prema Uredbi o klasifikaciji voda. Rezultati motrenja kakvoće vode potoka Črnec za period 2005.-2007. godine odstupaju od kakvoće vode određene II. odnosno III. kategorijom prirodnog prijemnika, i to od obveznih pokazatelja za: fizikalno-kemijske pokazatelje, režim kisika, mikrobiološke pokazatelje, hranjive tvari i biološke pokazatelje. Također, i neki od određivanih pokazatelja koji daju širu ocjenu opće ekološke funkcije voda i uvjeta korištenja voda za određene namjene su neodgovarajuće kakvoće za ispust u vode prirodnog prijemnika II. odnosno III. kategorije. Po svim određivanim pokazateljima kakvoće površinske vode potok Črnec se može smatrati otpadnom vodom, zbog ispusta otpadne vode industrije i ispusta javne kanalizacije, i stoga ne bi trebalo u potoku Črnec motriti pokazatelje kakvoće površinskih voda.

Abstract (english)

The aim of this paper is to determine the physical, chemical and biological indicators of the water quality from the brook Črnec - the natural receiver of the 2nd category in the upper part of the flow and 3rd category in the lower part of the flow. After the statistical processing the obtained results of the water quality indicator are compared with the regulated maximal permitted concentrations. Based on that, the waters are grouped in the determined category according to the Direction of water classification. The monitoring results of the water quality from the brook Črnec, for the period from 2005 – 2007 deviate from the water quality determined by 2nd , i.e. 3rd category of the natural receiver from the obligatory indicators for physical – chemical indicators, oxygen regime, microbiological indicators, nutrients and biological indicators. Some of the determined indicators which give broader evaluation of the general ecological function of waters and the conditions of water usage for defined applications have inappropriate quality to be let into the waters of the 2nd receiver, 3rd receiver respectively. After all the determined indicators on surface water quality, the brook Črnec can be considered to be the waste water, because of the outlet of the industrial water as well as of the sewage system, and the indicators of the surface waters quality should not be monitored in the brook Črnec becauese of that.
