“…The study areas with high EF values of Cu such as South Busan Port, North Busan Port, Tongyeoung Port, HaengamMan and Incheon Port have relatively long history for opening port with high traffic in South Korea. Therefore, it is considered that the anthropogenic sources of Cu and Zn were derived from antifouling paint of vessels, storm water drains and sewage discharges and also those of Cd and Pb caused by storm water drains and sewage discharges (Förstner 1979;Bothner et al 1998;Orlic and Tang 1999;Zago et al 2001;Turner 2010). And, the average EF values of Cr and Ni (0.99 and 1.05, respectively) represented relatively uncontaminated metals in the study areas.…”

Total concentrations of Cr, Ni, Cu, Zn, Cd and Pb in surface sediments were determined to investigate the regional trends of heavy metal contamination in 11 coastal areas in Korea. Enrichment factor (EF) of heavy metals was calculated by comparing the level of their regional background. The averages of EF values in study areas were 0.99 for Cr, 1.05 for Ni, 4.23 for Cu, 1.80 for Zn, 3.92 for Cd and 1.54 for Pb, respectively. Dilute HCl extractions were useful to deduce the anthropogenic sources of heavy metals and the 1 M HCl extractable fractions of each metal varied from 0.3 to 37.3% for Cr, 1.9 to 66.3% for Ni, 4.2 to 92.9% for Cu, 7.1 to 99.7% for Zn, 10.9 to 98.9% for Cd and 15.0 to 99.1% for Pb. Comparing 1 M HCl extractable fraction to total concentration, large portions of Cu, Zn, Cd and Pb were present as potentially bioavailable fractions from anthropogenic input and were significantly correlated with their EF values showing r [ 0.68.

“…3 for As, Cr, Hg, Ni, Pb and Zn in surficial samples of the lagoons. Reference data were separated into three major groups, to account for different anthropogenic pressures and environmental settings: industrial/urban areas (Tanner et al, 2000;Zago et al, 2001;Berg et al, 2001;Bellucci et al, 2002;Bertolotto et al, 2003;Adamo et al, 2005;Ferraro et al, 2006;McCready et al, 2006;Marmolejo-Rodriguez et al, 2007;Harikumar and Nasir, 2010;Nikolaidis et al, 2010), coastal areas (Taher and Soliman, 1999;Dauvalter and Rognerud, 2001;Zabetoglou et al, 2002;Sericano et al, 2001;Preda and Cox, 2002;Bertolotto et al, 2003;Kishe and Machida, 2003;Cuong and Obbard, 2006;Farkas et al, 2007;Nobi et al, 2007;Romano et al, 2010) and lagoons (Bellucci et al, 2002). The values measured in Vietnamese lagoons are by far among the lowest (up to one order of magnitude) of the entire set for all elements considered, being lower but comparable to other coastal systems.…”

Problem statement: After being dramatically hit by war events, Vietnam is presently experiencing a huge economical and social development. However, very few data, relative to pollution levels and trends, are available for the correct management of critical areas such as coastal lagoons, where many economical activities are linked to high value environmental features. Approach: A set of sediment cores from nine coastal lagoons of central Vietnam (Lang Co, Truong Giang, An Khe, Nuoc Man, Nuoc Ngot, Thi Nai, O Loan, Thuy Trieu and Dam Nai) were sampled in 2008 and analyzed to assess metal and (Al, Cd, Cr, Cu, Fe, Hg, Li, Mn, Ni, Pb, V, U and Zn) and As levels and historical trends. Results: Concentrations are generally low, with the exception of As, which often exceeds ERL guidelines and Ni that does the same at O Loan. In some cases, concentrations-depth profiles account for recent increasing trends but surficial values are still low when compared to both international guidelines and polluted sediments all around the world. Sediment grain size seems to affect the depth distribution of a number of metals and when normalized to the content of silt and clay, values are particularly high at Dam Nai and Thi Nai, due to the very coarse composition of surficial sediments. Conclusion: Metal concentrations in lagoon sediments derive from the composition of rocks and soils in the watersheds. However, recent increasing trends need for further monitoring.

Contents of Zn, Cd, Ni, Mn, Cu, Pb and Fe in 36 samples of Scots pine collected in 9 sites located in the Upper Silesia Province have been determined using AAS technique. The samples were digested before the analysis. On the basis of cluster analysis the existence of links between the quantitative composition, the sampling sites and the type of the matrix have been found. The coexistence of certain groups of elements was found and described.
