Abstract (en)
The aim of this PhD thesis was the determination of physicochemical
and microbiological parameters in water from artesian
wells in the region of Semberija. The study also included analysis of
factors which affect the mobility of chemical contaminants. Water
samples were taken in the period between February 2011 and
January 2012, with monthly sampling frequency. Artesian wells are
located in the north Semberija along the Sava River. Electrical
conductivity, pH value and temperature were determined in situ.
Orthophosphates, ammonium, nitrate and nitrite nitrogen were
determined spectrophotometrically, while chlorides and sulphates by
ion chromatography. Metals were determined by EAAS, EAAS and
ICP-OES techniques. Microbiological parameters were determined
using the pour plate technique, the method of membrane filtration
and the most probable number method. Obtained results have
shown that the water from artesian wells has a weak alkaline
character with a high salt content. The concentration of ammonia
nitrogen, orthophosphate, arsenic and manganese exceed the
exposure limits. Water from artesian wells is microbiologically safe,
except at one site (AB9). The presence of intestinal (faecal)
streptococci and sulfite-reducing clostridia, whose values exceed the
exposure limits, was detected in water from artesian well AB9.
Multivariate analysis of metals showed three clearly separated
clusters. In the first cluster are artesian wells AB1, AB2, AB3, AB4
and AB5, in the second cluster are AB6, AB7 and AB8, and in the
third cluster are AB9 and AB10. Obtained results have also shown
that the artesian wells are protected from human influence, and that
high levels of ammonia nitrogen, orthophosphate, arsenic and
manganese are the result of the geological composition of the soil.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
