Metal pollution is a global problem which represents a growing threat to the environment. Because of bioaccumulation and negative effects of heavy metals, their bioavailability needs to be monitored. Many studies showed accumulation of metals in crayfish tissues as dose-and time-dependent without significant differences in tissue concentration levels comparing males and females. Muscles and exoskeleton were considered as specific for accumulation of mercury and nickel, respectively. Cadmium, zinc, copper, lead, and chromium accumulated mainly in hepatopancreas. By analyzing these specific tissues, it is possible to deduce the bioavailability and, by presumption, the level of environmental pollution by specific metals. However, in the case of zinc and copper, their utility is limited to assessing bioavailability because rapid depuration of these metals renders them less useful for long-term environmental monitoring programs. The literature reporting heavy metal impacts on freshwater crayfish, with reference to accumulation levels, is reviewed and summarized with respect to their suitability as bioindicators. Summarized published data from unpolluted or control localities can be used as referential values in crayfish, and consequently help with evaluation of monitored sites.

“…The Mekong River Delta (MRD), a major agricultural region of Vietnam in which large amounts of chemical fertilizers are used, is a diffuse source of contaminants and nutrients which are added to the MRD waters. In addition, industrial activity in the area contributes organic matter, trace elements, and organic pollutants to the MRD waters; these pollutants may affect water quality [2] and are likely to be the source of the high levels of trace elements in the biota [3,4]. A large shipbuilding company located on Van Phong Bay (VP), Khanh Hoa Province, in the Central Coastal Zone (CCZ), one of the less densely populated areas in Vietnam, is reported to be one of the contamination hot spots in the country, causing pollution by trace elements [1,5].…”

Concentrations of trace elements in Meretrix spp. (Mollusca: Bivalva) along the coasts of Vietnam

The dominant coastal bivalve in Vietnam, hard clams Meretrix spp., collected from the South Key Economic Zone (SKEZ), the Mekong River Delta, and the Central Coastal Zone (CCZ) were analyzed for 21 trace elements. Comparison of the results from the three regions indicated that levels of most of the trace elements, especially As, Mo, Sn, and Pb, were highest in the samples collected from the CCZ, whereas most of the trace elements were found to be present at relatively low levels in samples from the SKEZ. The high concentrations of these trace elements in the CCZ, a sparsely populated region with less human activity than the other two regions, were believed to have originated from industrial waste produced in a shipyard. Although the trace element concentrations in the bivalves were within safe levels for human-consumption criteria reported by the United State Food and Drug Administration and the European Commission, estimation of cancer risk based on As concentration indicates that the hard clams from the CCZ pose a high risk to consumers.Thus, the industrial waste produced in the less densely populated region might increase the health risk to consumers via the contamination of bivalves commonly used as food.

“…Ikemoto et al (2008) reported high Mn, As and Ba in crustaceans from the Mekong River Delta, South Vietnam. Our previous studies on black tiger shrimp and giant river prawn from South Vietnam also found a high accumulation of Mn and Ba in the exoskeletons (Tu et al, 2008a;2008b).…”

“…Trace elements have been detected in various biota and environmental samples across this region and there has been concern about sources and concentrations in food items that are frequently consumed by humans and wildlife (Phuong et al, 1998;Anh et al, 2003;Ikemoto et al, 2008;Tu et al, 2008a;2008b;Agusa et al, 2009). However, little is known about the behaviors of trace elements within Vietnamese estuarine ecosystems, particularly with respect to biomagnification.…”

Problem statement: Ba Ria Vung Tau (BRVT), a Vietnamese province with one of the fastest growing economies in the country, faces significant environmental challenges, including increased contamination of rivers and estuaries with urban and industrial wastes. Approach: Concentrations of 23 trace elements and stable isotope ratios (δ 13 C and δ 15 N) were analyzed in suspended particulate matter, one species of peanut worm, one species of octopus, six species of crustaceans and 13 species of fish collected from an integrated shrimp mangrove farm in the BRVT. Results: Concentrations of Cu, Zn, Se, Mo, Ag, Cd, Sb and Bi in octopus, Mn, Sr and Ba in crustaceans and Hg in fish were the highest among organisms analyzed. Using δ 15 N values to identify trophic positions, we found that Zn, Se and Hg biomagnified through the food web. The slope for Hg (0.048) was remarkably lower than those reported for other aquatic food webs. In contrast, the concentrations of most trace elements followed reverse trends (i.e., decreasing concentrations with increasing trophic level). Trace element concentrations we measured in organisms were within safe levels for human consumption according to criteria established by the Ministry of Agriculture, Fisheries and Food (MAFF) in the UK. However, concentrations of Cu in black tiger shrimps and octopus and Zn in Commerson's glassy fish were higher than the MAFF guidelines. Conclusion: The results of this study highlight the usefulness of δ 13 C and δ 15 N as a tool not only for elucidating the trophic position of biota, but also for tracing contaminants within food webs.
