“…Although sediment lead concentrations at the location are not reported, the assumption is that there is significant influence from lead mine waste. We have previously observed generally low bioavailability of sediment bound lead to bivalves in both marine [9,41] and freshwater [8] lead bioaccumulation studies. The lead exposure sediment concentrations were 84.7 AE 14.2 mg/g, and water lead concentrations were 4.2 AE 0.1 mg/L, at base flow and 20.4 AE 0.6 mg/L, at high flow, similar to the lead concentrations at the Railway location of the Molonglo River ( Table 2).…”

“…The results of both studies with C. fluminea demonstrate relatively low lead accumulation relative to exposure concentrations in Corbicula. We have previously observed generally low bioavailability of sediment bound lead to bivalves in both marine [9,41] and freshwater [8] lead bioaccumulation studies. Although the tissue lead concentrations of C. australis in the present study are below the highly elevated sediment concentrations, it is important to note that any accumulation of lead is of concern, as it is a highly toxic metal with no known biological role.…”

A weight of evidence approach in environmental assessment includes the use of biomonitor organisms to measure biologically available contaminant concentrations and lethal and sublethal responses in an exposure, dose, and response framework. Corbicula australis was assessed as a test species for metal toxicity using in situ river sediment exposures at 4 locations in the Molonglo River (New South Wales, Australia), which has a legacy of sediment metal contamination, following 8 decades of mining in its upper reaches. A sediment metal contamination gradient was evident from 12.5 km to 47 km downstream of the mine, as follows: zinc (851-130 mg/kg) > lead (104-7 mg/kg) > copper (31-5 mg/kg) > cadmium (2-0.3 mg/kg). Exposed C. australis accumulated the following metals in tissue: zinc (1358-236 μg/g) > copper (24-20 μg/g) > cadmium (4.7-0.7 μg/g) = lead (4.2-1.8 μg/g). Biomarker responses showed increased sublethal impairment with increased tissue metal concentrations. Total antioxidant capacity was mildly impaired, with corresponding increased lipid peroxidation and lysosomal membrane destabilization at the higher tissue metal concentrations. Corbicula australis proved to be an effective biomonitor organism for sediment metal assessment, as it is able to accumulate metals relative to sediment concentrations and showed a pattern of increased sublethal impairment with increased tissue metal concentration. It is recommended as a suitable species for incorporation into local freshwater monitoring and assessment programs. Environ Toxicol Chem 2017;36:709-719. © 2016 SETAC.

“…Previous studies in bivalve molluscs have linked LD to oxidative stress and the breakdown of lipid membranes through LP (e.g. Marasinghe Wadige et al 2014 ; Taylor et al 2016 ). In the current study, there is no correlation between LD and either TAOC or LP.…”

The effects of multigenerational Cu exposure on the freshwater gastropod Isidorella newcombi were investigated. Snails were exposed to a range of treatment-specific Cu concentrations in the parental to F2 generations, and a common Cu concentration in the F3 generation. In the parental to F2 generations, some general responses to 3 days Cu exposures included reduced survival and feeding in snails exposed to higher Cu concentrations. This suggested that the snails exposed to the high Cu concentration were experiencing Cu-induced stress that may apply selection pressure. In the F3 generation, when all treatments were exposed to a common Cu concentration, increased survival was correlated with the pre-exposure Cu concentration history. Snails that had been pre-exposed to Cu also displayed reduced stress at a sub-lethal level, indicated by lower lysosomal destabilisation (LD). Mortality and LD responses in the F3 generation were not related to Cu tissue concentrations, indicating increased tolerance and reduced stress were not related to changes in Cu bioaccumulation. Total antioxidant capacity increased in the higher Cu concentration pre-exposure treatments which could be associated with lower Cu-induced stress, however, this is not supported by the oxidative damage marker lipid peroxidation, which also increased. While Cu tissue concentrations and oxidative stress markers were assessed to determine underlying reasons for increased tolerance in snails from a population with a multi-generational exposure history to Cu, the results were not conclusive. Despite this, it was demonstrated through increased survival and reduced LD that Cu tolerance can develop over a short evolutionary time scale.

“…This result was in agreement with those of Yap et al [50] who found that the Pb in the TST of Perna viridis had positive correlation (p < 0.05) with the Pb in the sediment. Marasinghe Wadige et al [51] studied the effect of Pb-spiked sediments on the freshwater bivalve, Hyridella australis. They found that a spike in Pb concentration in the sediments in laboratory conditions was able to cause an increase of Pb concentration in the soft tissues of H. australis.…”

This study aimed to analyse ten trace metal concentrations in the edible part of the freshwater clam Corbicula javanica and to provide a critical assessment of the potential risks to human health through consumption of this clam as food based on well-established indices and food safety guidelines. The clams were captured from a pristine original site and transplanted to other sites with different environmental qualities. The trace metal levels in the edible total soft tissue (TST) of the clam were below those of the food safety guidelines referred to except for Pb, which exceeded the permissible limit set by the European Commission (2006) and the US Food and Drug Administration/ Center for Food Safety and Applied Nutrition); Interstate Shellfish Sanitation Conference. (USFDA/CFSAN; ISSC) (2007). The estimated daily intake (EDI) values of the clam were found to be lower than the oral reference dose and the calculated target hazard quotient (THQ) and total THQ were found to be less than 1. Therefore, in conclusion, the human health risk for consumption of TST of C. javanica at both average and high-level were insignificant regardless of the environment it was exposed to.
