1999
Carnol, Monique | Cudlin, Pavel | Ineson, Phil
peer reviewed | The effects of enhanced (NH4)(2)SO4 (NS) deposition on Norway spruce (Picea abies [L.] Karst) fine root biomass, vitality and chemistry were investigated using root-free in-growth cores reproducing native organic and mineral soil horizons. The cores were covered and watered every 2 weeks with native throughfall or throughfall supplemented with NS to increase deposition by 75 kg ha(-1) a(-1) NH4+-N (86 kg ha(-1) a(-1) SO42--S). The in-growth cores were sampled after 19 months and assessed for root biomass, necromass, length, tip number, tip vitality and fine root chemistry. Root biomass and fine root aluminium (Al) concentration were negatively correlated, but NS deposition had no effect on root growth or root tip vitality. NS deposition caused increased fine root nitrogen (N) concentrations in the organic horizon and increased Calcium (Ca) concentrations in the mineral horizon. Fine root biomass was higher in the organic horizon, where fine root Al and potassium (K) concentrations were lower and Ca concentrations higher than in the mineral horizon. Results highlighted the importance of soil stratification on fine root growth and chemical composition.
Afficher plus [+] Moins [-]The importance of total organic carbon and trihalomethane formation potential in monitoring of groundwater and surface water quality
1999
Ivancev-Tumbas, I. | Dalmacija, B. (Prirodno-matematicki fakultet, Novi Sad (Yugoslavia). Institut za hemiju)
Determination of total organic carbon content (TOC) and trihalomethane formation potential (THMFP) as well as correlation of those two parameters is recommended for monitoring of water bodies which are considered as drinking water resources. Those parameters would enable a categorization of water bodies from the protection point of view as well as from view of their usage as drinking water sources. Relationship between TOC and THMFP is dependent on the origin and the structure of organic matter in water. In this paper the correlation of TOC and THMFP is given for different kind of resources.
Afficher plus [+] Moins [-]The bottom fauna as an indicator of the eutrophication level in some [water] reservoirs in Serbia [Yugoslavia]
1999
Simic, V. | Simic, S. (Prirodno-matematicki fakultet, Kragujevac (Yugoslavia). Institut za biologiju)
Important differences in the structure of fauna communities of their deepest parts of benthos were found in the investigation of several water reservoirs (Gruza, Grosnica, Barije, Bor, Vlasina and Medjuvrsje) on the territory of Serbia (Yugoslavia) lasting several years. The pronounced alterations of the structure are in the correlation to the pronounced degree of eutrofication was also established according to other indicators, above all according to the concentration of biogenic salts and the amount of organic substances. Characteristic group and taxa of the fauna of benthos which point to certain level of eutrophications were separated.
Afficher plus [+] Moins [-]Metal-pollution index (MPI) - proposal for freshwater monitoring
1999
Teodorovic, I. (Univerzitet u Novom Sadu, Novi Sad (Yugoslavia). Prirodno-matematicki fakultet, Institut za biologiju) | Djukic, N. | Maletin, S. | Miljanovic, B.
MPI - Metal Pollution Index is being proposed with an aim improving the freshwater pollution control, monitoring and classification based on fish metal body burden. This is a simple mathematical model which enables presentation of Cd, Pb, Cu, Zn and Al fish liver concentration as a single value. After thorough studies of bioaccumulation, biomagnification and tissue distribution patterns, liver of Carassius auratus gibelio has been chosen as sentinel organ. Normal distribution and biological variation assessment is being achieved by using normalizers - reference values (liver concentrations of selected elements in fish from reference sites Vruje and Moharac micro water reservoirs, Serbia (Yugoslavia)). Selected representative sites have been evaluated according to new classification of freshwater ecosystem based on MPI values.
Afficher plus [+] Moins [-]Oxygen aspect of water quality of Skadar lake [Montenegro, Yugoslavia]
1999
Djuraskovic, P.N. | Sabotic, R. (Hidrometeoroloski zavod Crne Gore, Podgorica (Yugoslavia))
Oxygen aspect of water pollution of Skadar lake, Montenegro (Yugoslavia) is considered in this paper. Water analysis data in the period of 1991-1998 were used to establish relevant parameters, oxygen saturation (%O2), and five day biochemical demind (BPK5). Those data were supplied by Hydrometeorological Institute in Podgorica, Montenegro (Yugoslavia). Measurements were taken from three places in northern part of Skadar lake, where the increased water pollution is expected, and from southeastern part of the lake, out of source of pollution directly influence. According to results from this research, there is close relation between water pollution and oxygen water balance. Parts of the Skadar lake with low water circulation are especialy susceptible (place Kamenik). In the 1991-1995 period, this phenomena is manifested with variation depending of the chosen area and year. After some improvement of water quality in the 1996-1997 period, there is noticeable increase of water pollution in 1998 at all places. Supersaturation was identified by the percentage of O2 in Skadar lake area at whole.
Afficher plus [+] Moins [-]Some aspects of the effects of lindane to the nutrition of Serranus scriba in the sea water
1999
Kovacevic, A. (Institut za biologiju mora, Kotor (Yugoslavia))
The experiment was performed on marine Teleost Serranus scriba with lower concentrations of lindane then MPC (due to our valid law). The aim of this study was to find the effects of lindane to fish activities connected with nutrition. This motive is among the strongest. It includes parameters as: number of fish movements in the presence of prey or without it and the number of onslaughts to the prey during one hour. The results have shown that the increasing of lindane concentration caused considerable decreasing and even complete cessation of activity. Interest for prey and decreasing activity of predators in the presence of prey (typical for Serranus - as a fish of prey and the hunter) endures till the moment of convulsion.
