“…It thus would be useful to link valve daily activity in C. fluminea for arsenic bioavailability and bioaccumulation directly. It suggests that valve daily rhythm-based biomonitoring linking with toxicokinetics and BLM is a useful tool to describe arsenic-gill binding interactions and to predict arsenic burden of soft tissue in the field situations (Liao et al 2007;Jou et al 2009). Gerhardt et al (2005) suggested that it is urgently needed to define daily rhythm changes as a new behavioral test parameter to provide a candidate factor for biomonitoring the aquatic contaminants.…”

The objective of this study was to use a quantitative process-based damage assessment model (DAM) associated with biotic ligand model (BLM) to examine the ecophysiological responses of freshwater clam Corbicula fluminea to waterborne arsenic. We carried out a 14-day exposure experiment to obtain bioaccumulation parameters and a 7-day acute toxicity bioassay to obtain survival data. To investigate the survival dynamics, we examined 2 key parameters characterizing bioaccumulation and damage regulation: capacity to eliminate body arsenic burden and reversible ability to recover the damage. Results show that uptake rate constant of 2.075 + or - 0.442 (mean + or - SE) ml g(-1) d(-1) during uptake phase and elimination rate constant was estimated to be 0.1995 + or - 0.022 d(-1). The derived bioconcentration factor of 10.401 ml g(-1) suggests that arsenic has a high potential for bioaccumulation in C. fluminea. Our results show that a negative association between bioaccumulation and the fraction of arsenic binding in biotic ligand at 50% mortality, indicating that C. fluminea with higher arsenic binding in gill biotic ligand at 50% mortality level gives a lower capacity to accumulate bioavailable arsenic. We found a linearly positive correlation between elimination rate and recovery rate constants. Yet, a potential tradeoff between ability to eliminate arsenic and ability to recover the damage is not found. We showed that an ecophysiological significance of C. fluminea exposed to arsenic can be revealed by the elimination-recovery regime. This research may also provide mechanistic insights into the development of biomonitoring organism such as C. fluminea mimicking metal bioaccumulation in a real situation.

“…For example, a mechanistic model to describe a "fluxbiological response" approach based on biotic ligand model (BLM) and Michaelis-Menten (M-M) kinetics to allow the linkage between valve closure behavior and sodium transport mechanism in freshwater clam C. fluminea in response to waterborne copper was developed. The M-M maximum Cu internalization flux in C. fluminea, a half-saturation affinity constant, dynamics of Na uptake and valve closure daily rhythm driven by external Cu could be predicted based on this "Na transport-valve closure behavior" approach, thus providing the basis of a future design of biomonitoring tool [116]. The proposed Cu-BLM-Corbicula model showed that free ionic form of waterborne Cu binding specifically to clam gill impaired normal valve closure behavior.…”

“…The LOEC of cadmium was 6.53 g L −1 for both species [115]. Based on the closure daily rhythm and the corresponding dose-response profiles, the valve closure behavior in the clam such as C. fluminea can be also used as a toxicity endpoint for the biomonitoring of the aquatic heavy metals [116].…”

“…Third, a statistical approach was developed, and it demonstrated its ability to use bivalves' closure response as a method for detecting trace amounts of metals (Tran et al 2003(Tran et al , 2007Fournier et al 2004). It is noteworthy that from our results and observations, Liao et al (2005Liao et al ( , 2006 and Jou et al (2009) developed mathematical models that describe the interaction between spontaneous valve daily rhythms and various valve response characteristics. In this study, we established two field stations, the first in the Bay of Arcachon, France, in February 2006 and the second one in the Havannah channel, New Caledonia, in August 2007.…”

The high-frequency measurements of valve activity in bivalves (e.g., valvometry) over a long period of time and in various environmental conditions allow a very accurate study of their behaviors as well as a global analysis of possible perturbations due to the environment. Valvometry uses the bivalve's ability to close its shell when exposed to a contaminant or other abnormal environmental conditions as an alarm to indicate possible perturbations in the environment. The modeling of such high-frequency serial valvometry data is statistically challenging, and here, a nonparametric approach based on kernel estimation is proposed. This method has the advantage of summarizing complex data into a simple density profile obtained from each animal at every 24-h period to ultimately make inference about time effect and external conditions on this profile. The statistical properties of the estimator are presented. Through an application to a sample of 16 oysters living in the Bay of Arcachon (France), we demonstrate that this method can be used to first estimate the normal biological rhythms of permanently immersed oysters and second to detect perturbations of these rhythms due to changes in their environment. We anticipate that this approach could have an important contribution to the survey of aquatic systems.
