ABSTRACT: Abstract: The amount of eroded material in the Republic of Serbia has decreased in the last few decades. The aim of this research is to analyse changes in soil erosion intensity in the Rasina watershed from 1971-2011 caused by factors including changes in land use, the population and number of households, migrations, and erosion control works. Due to changes in the intensity of erosion processes, the annual gross erosion in the study area decreased by 116140.2 m3year-1, while the sediment yield decreased by 52727.2 m3year-1. The value of the erosion coefficient was reduced from Z=0.39 in 1971 to Z=0.30 in 2011. In this 40 year period, there were no significant changes in natural conditions, and the anthropogenic influences were responsible for the reduced erosion intensity. In the Rasina watershed, almost 8.500 ha upstream from “Ćelije” dam were treated by bioengineering works. Since 1961, a decrease in the population was typical for all of the valley and mountain settlements in the Rasina watershed. The percentage of the population engaging in agriculture also decreased during this period, as did the general activity of the population. The analysis shows that the most significant reduction in livestock occurred in the mountain region, which has the best conditions for animal husbandry, followed by the hill region and finally the valley region. These results are the basis for water management projects, soil and environmental protection, spatial planning, agriculture and other human activities. Key words: soil erosion, demographic and land use changes, erosion control works, Serbia.Fresenius Environmental Bulletin 01/2014; 23(1a):254-263.

ABSTRACT: Dental unit water lines (DUWLs) provide a favorable environment for microbial biofilm formation due to the high surface in the tubing and the character of fluid dynamics in narrow, smooth-walled waterlines. In this study the level of microbial contamination of municipal water and DUWLs in 26 dental units including 16 private and 10 governmental dental units were measured in Bushehr. All steps for heterotrophic bacteria, total coliform and E.coli tests including sampling, preservation and laboratory examinations were performed according to the standard methods for water and wastewater examination. All high speed handpiece (ranged 2100-9600 CFU ml-1) and air-water syringe (ranged 1900-8500 CFU ml-1) samples for total heterotrophic bacteria exceed American Dental Association (ADA) standard for dental unit water. Total coliform tests were negative in all municipal water samples while 25% (ranged 2.2-5.1 MPN/100ml) of high speed handpiece and 25.8 percent (ranged 2.2-5.1 MPN/ 100ml) of air-water syringe samples were positive. Governmental units contamination was higher than private units and there were significant correlations between total heterotrophic bacteria count with working days per week and unit age.Fresenius Environmental Bulletin 01/2014;
