AB  - Plant available arsenic (As) is not defined by its total content but by the various forms in soil. The aims of this study were to determine the amounts of As phases in soils extracted in the vicinity of the antimony mines; to study soil surface processes affecting formation of most mobile phases of As and the identification of sources of As phases in C soil horizon. Five fractions of soil As were determined by sequential extraction analyses (As F1, As F 2, As F 3, As F 4 and As F 5) in A and C horizons. The identification of the origin of As fractions were made by mean of principal component analyses (PCA) including Pearson correlations. The amount of the most mobile forms of As (As F1 and F2) was below 1%. The content of As F1, As F2 and As F4 decrease with soil depth, while aqua regia As and phases F3 and F5 increase with depth. Principal component analyses (PCA) showed that the content of As F2 is affected by anthropogenic factor and the content of As F4 by biological factor. In C horizon, As F2 and F4 are influenced by the leaching processes in soil. Arsenic F5 is bound to sediment rocks. The soil surface processes increases the availability of As in soil. The most mobile forms of As were found in deeper soil horizon that is due to the leaching of As with water from biological sources. The content of semi available phase of As F3 increases with depth, with stronger bounds due to the linkage to the amorphous Fe hydroxides.

AB  - Biodegradation of phenol in four natural soils (loamy sand, sandy loam, sandy clay loam and loam) by indigenous microorganisms and in soils augmented by the Bacillus sp. PS11 was studied. During the laboratory soil microcosm experiments, the total removal of 2 g of phenol per kg of soil was achieved in all soil types in between 6 and 21 days. All biodegradation data was found to fit very well to saturation kinetics. The most efficient phenol removal was observed in the loamy woodland soil that contained the least amount of sand (42.5%) and the most silt and clay fraction (57.5%) in comparison to other three soil samples. However, amending sandy loam sample to contain more clay (from 13.5% to 30%) negatively affected the phenol removal rate, while increasing sand content (from 74.4% to 90%) resulted in the two times faster phenol removal in comparison to natural soil type. Bacillus sp. PS11 performed well in both pure culture and in the presence of soil microorganisms. Indigenous bacteria from sandy clay loam soil type possessed the ability of phenol bioremediation and almost whole amount of added phenol (2 g kg soil(-1)) was degraded within 9 days, whereas augmentation by Bacillus sp. PS11 improved the phenol removal by 20%. Carrying out small scale soil model experiments and amending soil granulometric properties by addition of clay or sand minerals is suggested as an effective and economically interesting way of enhancing bacterial soil bioremediation.

AB  - The changes in inorganic and organic phosphorus (P) fractions of soil resulting from long-term fertilization (40 years) were investigated. In order to improve understanding of the sink and sources of phosphorus, P-fractions were extracted from soil samples from depths of 0-30 and 30-60 cm with different amounts of monoammonium-phosphate (MAP) and then determined. The studied soil was of the Stagnosol type. Phosphate fertilizer was applied in 26, 39 and 52 kg P ha(-1) amounts during a period of 40 years. Samples were subjected to sequential extraction according to a modified Chang and Jackson method and the Community Bureau of Reference (BCR) sequential extraction procedure in order to extract different forms of phosphorus. The certified reference material CRM 684 (river sediment extractable phosphorus) was used to confirm the accuracy of the instrument and of both employed methods. Furthermore, the association of phosphorus with substrates was provided by comparison of the results of sequential methods of phosphorus species with the sequential extraction of metals (Fe, Al, Mn and Ca). The results of continuous fertilization during 40 years indicated increases of all forms phosphorus in the soil except of phosphorus bound to calcium and organic phosphorus. Application of higher amounts of P-fertilizer resulted in the dominance of the Al P fraction in the studied soil, which indicated that this fraction was the most responsible for the migration of phosphorus along the soil profile.
AB  - U ovom radu ispitivane su promene u frakcijama neorganskog i organskog fosfora (P) u zemljištu koje su izazvane 40 godišnjim đubrenjem amonijum-fosfatom (MAR). Đubrivo je dodavano u količinama od 26, 39 i 52 kg P po hektaru zemljišta. U cilju praćenja mobilnosti fosfora, ekstrahovane su fosforne frakcije sa dve različite dubine zemljišta: površinski sloj od 0-30 cm i dubina od 30-60 cm. Tip ispitivanog zemljišta je Stagnosol. Uzorci su u cilju ekstrahovanja različitih oblika fosfora podvrgnuti sekvencijalnoj ekstrakciji i to na dva načina: prema modifikovanoj Chang i Jackson metodi i BCR metodi. Sertifikovani referentni materijal CRM 684 (rečni sediment) je korišćen za praćenje tačnosti obe korišćene metode. Osim toga je proučeno vezivanje fosfora sa supstratima (Fe, Al, Mn i Ca) koji su ekstrahovani sekvencijalnom ekstrakcijom metala. Rezultati ukazuju da kontinualno 40 godišnje đubrenje dovodi do povećanja sadržaja svih oblika fosfora u zemljištu osim fosfora koji je vezan za kalcijum i organskog fosfora. Primenom veće količine fosfornog đubriva dolazi do dominacije frakcije fosfora vezanog za aluminijum u ispitivanom zemljištu što ukazuje da je ta frakcija najodgovornija za migraciju fosfora kroz zemljište.
