Metals distribution and particle size analysis in water and sediment of the Djetinja river and Dragica spring (Serbia)

Abstract

This paper reports the results on total metal concentration (Al, Fe, Cr, Cu, Ni and Zn) in water and sediment of the Djetinja river basin in the area of western Serbia. Samples were collected in spring season. Based on the comparison of the concentrations of all analyzed metals it is possible to differentiate two zones: zone I (sampling sites 1-4), affected by the discharge of the Dragića spring, and zone II (sites 5-8), affected by the confluence of the Dragića spring with the Djetinja river. The analysis of suspended solid particle size in water as well as in sediment samples was performed in size range 0.02-2000 μm and a positive corelation was found with the concentration of aluminium, zinc, iron and nickel in water samples. The study of particle size and metals distribution through the river basin of the Djetinja was a useful tool for getting information about the distribution degree of the polluting agents, and their possible evolution growth and pollution sources. The research of metals distribution and particle size analysis in water and sediment of the Djetinja river and Dragića spring (Serbia) was conducted for the first time.

Metal concentration and particle size distribution of stream and river water polluted from copper rolling mill industry

“…The seasonal variations of the chemical composition of surface water are generally influenced by water level (i.e., dilution), as well as by anthropogenic factors: mining, industrial, urban, and agricultural activities (Reza and Singh 2010; Zare Garizi et al 2011). Heavy metal concentrations for samples collected in summer 2009 were compared with the results collected during the spring season 2009, at the same sites, reported in (Kiurski et al 2010). It was observed that at sites S1-S4, Cu and Zn concentrations were approximately 10 to 50 times lower during the summer, while at sites S5-S8, the summer and spring values were on the same order of magnitude, as could be seen in Fig.…”

“…The results from this campaign (Kiurski et al 2010) showed high concentrations of Cu and Zn in both water and sediment which required further monitoring. The results from the second sampling campaign carried out during the summer of 2009 are reported in this paper.…”

Temporal and Spatial Distribution of Arsenic Speciation in Sediments of Plateau Lakeside Wetland and Their Relations to Environmental Factors

“…The lakeshore area is an important area of interception of pollutants, between lake and lake, lush vegetation. The results showed that the arsenic speciation in F1 and F2 is relative to other forms of influence is weak, and the main environmental parameters pH, OM, Eh, W-DTP, S-DTP, and Lake area is not associated with the sediment grain size, heavy metals in soil and showed obvious effect of the particle size, particle size and soil the weak correlation between heavy metals, may be due to the different particle size of sediment in different proportions to adsorption of heavy metals, less sand in soil, but soil texture in a larger proportion of heavy metal content of total contribution is large, leading to higher content of heavy metals in sediments of the study area, and on the heavy metal adsorption capacity of clay soil a large proportion of the total amount of heavy metals with smaller and smaller [35][36] . F1, F2 and weak influence itself belong to the bioavailable environment state and the Lake District, F2 (Fe/Mn oxides and hydroxides) in the presence of oxygen on the heavy metals fixation plays a leading role; in hypoxic conditions, metal sulfide plays a leading role in metal speciation, due to oxidation and reduction the rise in potential, sulfide and organic binding state of the form can be transformed into unstable F1 [37] .…”
