“…The high correlation of Pb and Cd likely occurred from the manufacture of batteries (Huong et al 2007) and combustion of coal (Bac and Hien 2009) within the RRD. In addition, the significant correlations between Pb and Zn in both cores suggested that these trace elements may have originated more from atmospheric fallout (Bac and Hien 2009) or urban and agriculture surface runoff (Brack and Stevens 2001). Silver (Ag) has been used in recent years as a tracer of municipal effluents because of its low abundance in the crust and the fact that there are numerous anthropogenic sources (e.g., dentistry, photoprocessing) which are often added to wastewater discharge (Feng et al 1998;Hornberger et al 1999).…”

Historical profiles of trace element concentrations were reconstructed from two mangrove sediment cores collected within the Ba Lat Estuary (BLE), Red River, Vietnam. Chronologies of sediment cores were determined by the 210 Pb method, which showed that each respective sediment core from the south and north entrances of BLE provided a record of sediment accumulation spanning approximately 100 and 60 years. The profiles of Pb, Zn, Cu, Cr, V, Co, Sb, and Sn concentrations markedly increased from the years of the 1920s-1950s, and leveled out from 1950s-1980s, and then gradually decreased from 1980s to present. The profiles of Cd and Ag concentrations increased from 1920s-1940s, and then decreased from 1940s to present. The profile of Mo concentrations progressively increased from 1920s-1980s, then decreased to present. The Mn concentrations failed to show a clear trend in both sediment cores. Results from contamination factors, Pearson's correlation, and hierarchical cluster analysis suggest that the trace elements were likely attributed to discharge of untreated effluents from industry, domestic sewage, as well as non-point sources. Pollution Load Index (PLI) revealed levels higher than other mangrove sediment studies, and the longterm variations in PLI matched significant socioeconomic shifts and population growth in Vietnam. Geoaccumulation Index showed that mangrove sediments were moderately polluted by Pb and Ag, and from unpolluted to moderately polluted by Zn, Cu, and Sb. The concentrations of Pb, Zn, Cu, Cr, and Cd exceeded the threshold effect levels and effect range low concentrations of sediment quality guidelines, implying that the sediments may be occasionally associated with adverse biological effects to benthic organisms.

“…Göteborg harbor, located in the outlet of the Göta älv River, is the largest general oil port in Scandinavia. The harbor water and sediment are known to be contaminated with various anthropogenic substances and several toxic compounds, including PCBs, PAHs, tributyltin, dioxins, and heavy metals such as Hg . Stenungsund is located in the vicinity of the largest petrochemical industry in Sweden.…”

A broad biomarker approach was applied to study the effects of marine pollution along the Swedish west coast using the teleost eelpout (Zoarces viviparus) as the sentinel species. Measurements were performed on different biological levels, from the molecular to the organismal, including measurements of messenger RNA (mRNA), proteins, cellular and tissue changes, and reproductive success. Results revealed that eelpout captured in Stenungsund had significantly higher hepatic ethoxyresorufin O‐deethylase activity, high levels of both cytochrome P4501A and diablo homolog mRNA, and high prevalence of dead larvae and nuclear damage in erythrocytes. Eelpout collected in Göteborg harbor displayed extensive macrovesicular steatosis, whereby the majority of hepatocytes were affected throughout the liver, which could indicate an effect on lipid metabolism. Results also indicate that eelpouts collected at polluted sites might have an affected immune system, with lower mRNA expression of genes involved in the innate immune system and a higher number of lymphocytes. Biomarker assessment also was performed on livers dissected from unborn eelpout larvae collected from the ovary of the females. No significant differences were noted, which might indicate that the larvae to some extent are protected from effects of environmental pollutants. In conclusion, usage of the selected set of biological markers, covering responses from gene to organism, has demonstrated site‐specific biomarker patterns that provided a broad and comprehensive picture of the impact of environmental stressors.
