“…The age profile of this study population (mean age = 64 years ) would suggest that hand to mouth activity was not a significant exposure route. However, it has been reported that there was a direct link between soil metal levels and indoor dust levels (Fergusson and Kim, 1991 ) and since the levels of arsenic in dusts were correlated with those in soils it suggests that there may be an exposure pathway linking garden soil to urinary arsenic levels. Body burden has been seen to be raised in results of a locally run study.…”

A coal -burning power station in the Nitra Valley in central Slovakia annually emitted large quantities of arsenic ( up to 200 tonnes ) between 1953 and 1989. Since then, pollution -control measures have reduced arsenic emissions to less than 2 tonnes a year. However, the power station was still a source of airborne arsenic pollution. As part of an EU -funded study on exposure to arsenic and cancer risk in central and Eastern Europe we carried out a study of environmental levels of arsenic in the homes and gardens of residents of the district. Garden soil samples ( n = 210 ), house dust samples ( n = 210 ) and composite house dust samples ( n = 109 ) were collected and analysed using inductively coupled plasma atomic absorption spectroscopy ( ICP -AES ) at Imperial College. The mean arsenic content of coal and ash in samples taken from the plant was 519 g / g ( n = 19 ) and 863 g / g ( n = 22 ), respectively. The geometric mean ( GM ) arsenic concentration of garden soils was 26 g / g ( range 8.8 -139.0 g / g ), for house dust 11.6 g / g ( range 2.1 -170 g / g ) and for composite house dust 9.4 g / g ( range 2.3 -61.5 g / g ). The correlation between the arsenic levels in soil and in house dust was 0.3 ( P < 0.01 ), in soil and composite house dust 0.4 and house dust and composite house dust 0.4 ( P < 0.01 for both ), i.e., were moderate. Arsenic levels in both house dust and soil decreased with distance from the power station. Overall, levels in both fell by half 5 km from the point source. Weak correlations were seen between the total urinary arsenic concentrations and arsenic concentrations in composite house dust.

“…Approximately 75 % of Pb contained in leaded gasoline gets emitted directly into the atmosphere. Only 25 % of Pb released by vehicles being in coarse fraction gets deposited close on roads, and the remaining fine fraction remains airborne contaminating areas more remote from the point of its emission (Fergusson and Kim 1991). Lead deposited in the road dust and vehicular traffic in urban soils having less mobility stays on the surface soil.…”

The present study was conducted along three major highways namely State Highway (SH49), National Highway (NH66 and 45A) connecting Puducherry (India) for assessing heavy metals and total petroleum hydrocarbon contamination from surface soils in close proximity at a depth of 0-15 cm into automobile repair workshops and agricultural fields located beside the highways. Contamination levels of copper, lead, zinc, manganese, cadmium and chromium were assessed in the surface sediments soil on the basis of geoaccumulation index, contamination factors and spatial variability. The results revealed that sampling sites in the proximity to automobile workshops were moderately to considerably pollution impacted as compared to soil from agricultural fields along highways suggesting a direct influence of anthropogenic activities on levels of contamination. Pearson correlation indicated a strong association of total petroleum hydrocarbon with copper, lead and zinc suggesting that the metal contaminants from roadside surface soil had emanated from a common source.

IntroductionSoils are the major sink for heavy metals released into the environment by anthropogenic activities; most metals released to the environment do not undergo microbial or chemical degradation, Earthworm casts as a sampling medium -a case study from highly contaminated Hg roasting site P�enk (Idrija area, Slovenia) AbstractIn this study an interesting sampling medium -earthworm casts was examined in a highly Hg contaminated area. Enrichment factor (EF) has been applied to assess elevated concentrations of analyzed elements in earthworm casts and to determine elevated concentrations of these elements in soils and casts with regard to European average concentrations in topsoil. In a previous study (TeR�i~ & gosaR, 2012) it was shown that Hg contents and dispersion in casts from studied roasting site are comparable to those in soil, which indicates that soil contamination is substantially reflected in contamination of earthworm casts. Therefore the comparison between elemental concentrations in earthworm casts and soil was investigated with the intention to assess the reflection of possible soil contamination in casts. Besides Hg contamination, elevated concentrations of As, Ca, Cd, Mo, Pb and U were also determined in earthworm casts. The calculated EFs show moderate enrichment of casts with Ca, Sr and P and minimal enrichment with Mg, Zn and Cu. Cast, SOM (surface organic matter rich soil layer) and soil enrichments with regard to the European averages show extreme enrichment of all studied media with Hg, followed by significant enrichment with Mo and Cd and moderate enrichment with As. Spatial distributions of analyzed elements in casts mostly show similar pattern as in soil, however, because of the different nature of different earthworm species and specific properties of different elements, the data about cast contamination can only serve as an approximate prediction about the dispersion and distribution of contaminant in soil. Izvle~ekNa mo~no obremenjenem okolju živosrebrne žgalnice v okolici Idrije smo raziskovali zanimiv vzor~ni medijdeževnikove iztrebke. Faktor obogatitve (EF) smo uporabili za oceno povi�anih vsebnosti analiziranih elementov v deževnikovih iztrebkih in tleh ter za primerjavo s povpre~nimi vsebnostmi v tleh Evrope. Predhodna (TeR�i~ & Gosar, 2012) in ta �tudija sta pokazali, da so Hg vsebnosti in prostorska porazdelitev v deževnikovih iztrebkih dobro primerljive z vsebnostmi in porazdelitvijo v tleh na raziskovanem ozemlju, kar kaže da se onesnaženje tal dobro odraža v vsebnostih v deževnikovih iztrebkih. Primerjavo med vsebnostmi kemijskih elementov v deževnikov iztrebkih in tleh smo raziskovali z namenom, da bi ocenili stopnjo ujemanja vsebnosti elementov v deževnikovih iztrebkih in tleh. Poleg povi�anega Hg smo dolo~ili tudi povi�ane koncentracije As, Ca, Cd, Mo, Pb in U v deževnikovih iztrebkih. Izra~unani faktorji obogatitve (EF) so pokazali zmerno obogatitev v iztrebkih z Ca, Sr in P ter rahlo obogatitev z Mg, Zn in Cu. Vsebnosti v deževnikovih iztrebkih, vrhnjem z organsko...
