AB  - Geochemical investigations in order to identify the mineral deposits, as well as the sources of water supply of rural settlements included in the area of Bela Crkva, between the Nera and the Karaš rivers, draining the Neogene and Quaternary sediments. During the prospecting, water samples were collected from surface water streams, springs, wells, drills, water reservoirs, as well as the samples of stream sediments and rocks. Hydrogeochemical investigations are of significance, where, in the water of Vrsac hills, elevated levels of radionuclides U, Ra and Rn, and other toxic elements were detected with values above maximum allowed concentrations for drinking water. The wells of rural households had increased levels of Fe and Mn, as well as the increased mineralization, conductivity, and nitrogen cycle. The concentration of heavy metals in water wells was increased in the most settlements around Bela Crkva, as well as in Češko Selo, Banatska Subotica, Kuštilj, Jablanka and Karaš river. From the water accumulations formed in the Quaternary sediments southwest from Bela Crkva, samples of water, mud, overbank sediments, and A-horizon were collected. The water samles were determined on: Na, K, Ca, Mg, Fe, Mn, Al, NH4, NO3, SO4, HCO3, Cl, F, Ep, Eh, pH value, mineralization, Pb, Cd, Co, Ni, Cr, Cu, Zn, H2S, O2, CO2, U, Ra, Rn, As, Hg, Br. In the solid samples, Au, Ag, Pb, Zn, and other elements, as well as the content of 238U, 232Th and 40K were determined. Test results are presented in tables, diagrams, and hydrogeochemical maps.
AB  - Geološko-geohemijska istraživanja u cilju identifikacije ležišta mineralnih sirovina, kao i izvorišta za vodosnabdevanje ruralnih naselja obuhvatila su područje Bele Crkve, između reka Nere i Karaša, koje dreniraju sedimente Neogena i Kvartara. U toku prospekcije, prikupljeni su uzorci voda iz površinskih tokova, izvora, bunara, bušotina, vodenih akumulacija, potočnih sedimenata i uzorci stena. Značajna su hidrogeohemijska ispitivanja, u kojima su u vodama otkriveni povišeni sadržaji radionuklida U, Ra i Rn u području Vršačkih brda, kao i drugih toksičnih elemenata, čije su vrednosti iznad maksimalno dozvoljenih u vodi za piće. U bunarima seoskih domaćinstava povećani su sadržaji Fe, Mn, a povećani su i mineralizacija, provodljivost i azotni ciklus. Koncentracija teških metala u bunarskim vodama je povećana u većini naselja oko Bele Crkve kao i u naseljima Češko selo, Banatska Subotica, Kuštilj, Jablanka kao i reka Karaš. Od vodenih akumulacija nastalih u kvartarnim sedimentima JZ od Bele Crkve; prikupljeni su uzorci voda muljevite komponente s dna jezera, overbank sedimenata i A-horizonta. U uzorcima voda određivani su : Na, K, Ca, Mg, Fe, Mn, Al, NH4, NO3, SO4, HCO3, Cl, F, Ep, Eh, pH, mineralizacija, Pb, Cd, Co, Ni, Cr, Cu, Zn, H2S, O2, CO2, U, Ra, Rn, As, Hg, Br, u čvrstim uzorcima Au, Ag, Pb, Zn, U i dr. elementi, kao i sadržaji U, Th i 40K. Rezultati ispitivanja prikazani su: tabelama dijagramima i hidrogeohemijskim kartama.

AB  - Continuous long-term monitoring of aquatic systems is important for understanding their complete
evolution in order to monitor changes in the trophic status and water quality. The continuous
monitoring during a period of 20 years, by sampling once a month at two locations, the water
quality of reservoir “Grlište”, which is used for the water supplying town Zaječar (Eastern Serbia),
is observed and developmental stages in the life of the reservoir were determinated. It
should be noted that the obtained results were used also in the purpose of finding a cause of cyanobacteria
bloom, as a consequence of algal production. Limiting factors of algal production usually
were nitrogen and phosphorus, however, in this study, obtained results of subtraction between
trophic state index, calculated through total chlorophyll a (TSIChl-a) and trophic state index, calculated
through total phosphorus (TSITP), indicated that limiting factor of algal production was light.
On the basis of the concentrations of dissolved oxygen (DO), total phosphorus (TP) and chlorophyll
a (Chl-a) in the surface and in the bottom, it was concluded that the reservoir passed through
four development phases during the examined period. Results of long-term monitoring showed
that in the first years after the formation of the reservoir, the highest trophicity was detected (hypereutrophic
status), but later the reservoir mostly maintained eutrophic status.

AB  - In the purpose of monitoring the change of trophic status and water quality in the reservoir Grlište, in the period of 20 years, once a month sampling of water was conducted at two places. The obtained results were used in the purpose of finding a cause of cyanobacteria bloom which appeared in the dry years in the time of critically low water level in the reservoir. On the basis of the obtained results of analyzed parameters, the trophic state indexes of Carlson (TSIChl-a, TSITP and TSISD) were calculated and difference between TSIChl-a and TSITP showed that phosphorus was not a limiting factor of algal production. Content of nitrogen in tributaries of the reservoir was in creased in the examined period, but research results indicated that limiting factor of algal production was light, not nitrogen and phosphorus. On the basis of the concentrations of dissolved oxygen, total phosphorus and chlorophyll a in the surface and in the bottom, it was concluded that the reservoir went through four development phases during the examined period.

AB  - U cilju praćenja promene trofičkog statusa i kvaliteta vode u akumulaciji Grlište, u periodu od 20 godina, jednom mesečno je vršeno uzorkovanje vode i to na dva mesta. Dobijeni rezultati su korišćeni u svrhu pronalaženja uzroka cijanobakterijskog cvetanja, koje se javljalo u sušnim godinama u vreme kritično niskog nivoa vode u akumulaciji. Sadržaj azota u pritokama akumulacije je bio u trendu porasta u ispitivanom periodu, ali rezultati istraživanja su ukazali da je limitirajući faktor algalne produkcije bila svetlost a ne azot i fosfor. Na osnovu dobijenih rezultata analiziranih parametara, izračunati su Carlson-ovi indeksi trofičnosti (TSIChl-a,TSITP i TSISD-a) a razlika TSIChl-a i TSITP je ukazala da fosfor nije bio ograničavajući faktor algalne produkcije. Na osnovu koncentracija rastvorenog kiseonika, ukupnog fosfora i hlorofila a na površini i na dnu, zapaženo je da je akumulacija tokom ispitivanog perioda prošla kroz četiri razvojne faze. Uočeno je da je u prvim godinama nakon formiranja akumulacije trofičnost bila najizraženija (hipereutrofan status), da bi u daljem periodu zadržala uglavnom eutrofan status.
