“…The mean concentrations in soft Tivela mactroides tissue found in Playa Chocolate are within the range of values determined in previous works for the same species of bivalve at the same sampling area (LaBrecque et al 2004a, Alfonso et al 2005. No known values have been reported for trace metals for Crassostrea rhizophorae and Thalassia testudinum in Venezuela.…”

“…Tivela mactroides and Crassostrea rhizophorae are two species of bivalves abundant along the Venezuelan coast and widely consumed by local populations. The clam Tivela mactroides has been considered to be a potential biomonitor of trace metals in Venezuelan marine ecosystems (LaBrecque et al 2004a, Alfonso et al 2005, Jaffe et al 1995. It is well known that seagrasses are critical to the structure and function of many marine ecosystems (Klumpp et al 1989).…”

The bivalve mollusks Tivela mactroides and Crassostrea rhizophorae are abundant along the Venezuelan coast and are widely consumed as seafood. The globally important seagrass Thalassia testudinum is also abundant in Venezuelan. We report the concentrations of Cd, Cr, Cu, Ni, V and Zn in the soft parts of Tivela mactroides and Thalassia testudinum, and the concentrations of Cd, Cr, Cu and Ni in the soft parts of Crassostrea rhizophorae, in seven Venezuelan coastal sites. Metal concentrations were determined by Inductively Coupled Plasma Optical Emission Spectroscopy. Statistical analysis (one-way ANOVA) indicated that the organisms had different levels of metal bioaccumulation, and might be used as biomonitors for trace metals. Significant site-specific differences were found for the elements Cd, Cr, Ni and V in Tivela mactroides;

“…El ingreso y absorción de Cu tiene clara relación con su biocinética, la eficacia de asimilación, la tasa de alimentación de los organismos o la entrada de estos metales provenientes de efluentes (Pan y Wang 2009). Algunos investigadores como Bonilla et al (1995) y LaBrecque et al (2004 han reportado altos niveles de este metal en sedimentos superficiales, lo que permite la disponibilidad en el medio. Según Fernández et al (2007), las concentraciones de Cu en este bivalvo en costas venezolanas varían de 58.9 a 152 µg/g de masa seca, y sus promedios son similares a los encontrados en esta investigación.…”

“…Sediments were stored in polyethylene containers and transported to the laboratory. Clams were collected manually, and the exterior (shells) of the clams were well rinsed with seawater to eliminate marine sediments before being transferred to the bottles filled with distilled deionized water (LaBrecque et al, 2004). After the bottles were closed, they were placed in an iced cooler, for transportation to the laboratory.…”

“…Marine bivalves, including clams, mussels and oysters, can be employed as bioindicators to assess the marine environment, since they can accumulate (concentrate) trace elements and other substances (LaBrecque et al, 2004). In addition to using bivalve molluscs as bio-indicator organisms of coastal contamination, it is also recognized that they can be important links for contaminants between sediments and higher organisms, including man, that consume them.…”

Suspended particulate matter (SPM), sediments and clams were collected at three sites in Jiaozhou Bay to assess the magnitude of trace metal pollution in the area. Metal concentrations in SPM (Cu: 40.11-203; Zn: 118-447; Pb: 50.1-132; Cd: 0.55-4.39; Cr: 147.6-288; Mn: 762-1670 microg/g), sediments (Cu: 17.64-34.26; Zn: 80.79-110; Pb: 24.57-49.59; Cd: 0.099-0.324; Cr: 41.6-88.1; Mn: 343-520 microg/g) and bivalves (Cu: 6.41-19.76; Zn: 35.5-85.5; Pb: 0.31-1.01; Cd: 0.51-0.67; Mn: 27.45-67.6 microg/g) are comparable to those reported for other moderately polluted world environments. SPM showed a less clear pattern. Metal concentrations in sediments displayed a clear geographical trend with values increasing with proximity to major urban centers. The clams (on dry weight) showed a complex pattern due to the variability introduced by age-related factors. Cd showed an apparent reverse industrial trend with higher concentrations in clams collected at distant stations. Zn, Pb and Mn showed no clear geographical pattern, whereas Cu increased in the clams collected in the most industrialized area. In addition, the bioaccumulation factors (BAF) were calculated. The result indicated that the studied Ruditapes philippinarum in Jiaozhou Bay possessed different bioaccumulation capacities for Cd, Zn, Cu, Pb and Mn, and Cd, Zn had a relatively high assimilation of those metals from sediment particles. A significant relationship with clam age was observed for Zn (positive) and Cu (negative) suggesting different physiological requirements for both metals with age. Trace metal concentrations measured in the tissue of the investigated clam were in the range considered safe by the WHO for human use.
