Uptake of cadmium from water by freshwater animals has been well documented. However, little attention has been given to the importance of dietary and combined exposure as the source for uptake. In the present study, we compared cadmium uptake from waterborne (water-only), dietary (food-only), and combined (water plus food) exposures on the freshwater cladoceran Ceriodaphnia dubia. Major test end points included cadmium whole-body burdens, feeding rate, and reproduction. The C. dubia three-brood reproduction tests were conducted according to U.S. Environmental Protection Agency methods. The results indicated that cadmium was accumulated from both water and diet. Whereas the results showed that uptake from water was more rapid than uptake from diet, both uptakes occurred independently, and cadmium concentrations in C. dubia were additive from both sources. Furthermore, the present study found cadmium trophic transfer between primary producers (i.e., Pseudokirchneriella subcapitata) and primary consumers (i.e., C. dubia). Feeding rate was reduced from all avenues of exposure. Feeding reduction in combined exposure was affected additively by waterborne and dietary cadmium. Also, reductions in neonate production were observed after exposure to all three exposure types. Both body burden and reduced feeding affected C. dubia reproduction. These results indicate the importance of both waterborne and dietary cadmium exposures as the sources for metal uptake and toxicity.

“…Effect of feeding rate on reduced reproduction was considered as an indirect response [35,[41][42][43][44]. It was speculated that reduction of feeding would reduce the amounts of nutrients and, subsequently, the amount of energy available for growth and reproduction.…”

“…Consequently, we believe that mixture ecotoxicological investigations on whole organism or levels beyond individuals will benefit from assessing ecotoxicological modes of action that can be easily evaluated just studying the concentration at which lethal effects on embryos, juveniles, and adults occur and food acquisition is impaired. In Daphnia, other cladoceran, copepod, and polychaete species such analysis required only short-term acute and sublethal assays. − ,− Thus future research needs should focus in extending the proposed operational phenomenological mode of action procedure to other taxa and toxicant groups.…”

When considering joint toxic apical effects at higher levels of biological organization, such as the growth of populations, the so-called pharmacological mode of action that relies on toxicological mechanistic effects on molecular target sites may not be relevant. Such effects on population growth rate will depend on the extent to which juvenile and adult survival rates and production rates (juvenile developmental rates and reproduction) are affected by toxic exposure and also by the sensitivity of population growth rates to life-history changes. In such cases, the ecotoxicological mode of action, defined as the crucial life-history trait processes and/or xenobiotic-life-history trait interactions underlying a toxicological effect on population growth rate, should be considered. Life-table response experiments with the crustacean Ceriodaphnia dubia exposed to single and ternary mixtures of nine compounds were conducted to test the hypothesis that joint effects on population growth rates could be predicted from the mixture constituent ecotoxicological mode of action. Joint effects of mixtures containing pharmacologically dissimilar compounds (cadmium, λ-cyhalothrin, and chlorpyrifos) that differentially affected life-history traits contributing to population growth rates were accurately predicted by the independent-action concept. Conversely, the concentration-addition concept accurately predicted joint effects of two different mixtures: one containing pharmacologically similar acting pyrethroids that also affected similarly life-history traits, the other one that included pharmacologically dissimilar compounds (3,4-dichloroaniline, sodium bromide, and fenoxycarb) acting mainly on reproduction rates. These results indicate that when assessing combined effects on population growth rate responses, selection of mixture toxicity conceptual models based on the ecotoxicological mode of action of mixture constituents provided more accurate predictions than those based on the pharmacological mode of action.

“…For example, such hormetic responses have been observed for cholinesterase activity in daphnids exposed to 2 organophosphorus insecticides (Li and Tan 2011), for the feeding rate and locomotion of gammarids exposed to a carbamate pesticide (Xuereb et al 2009b), and for the reproduction of daphnids exposed to cadmium and to an endocrine disruptor (Calabrese 2005). Such inductions could be explained by "compensating metabolism" or the increased need for energy for defensive metabolic function (Orchad et al 2002). Actually, we are not able to explain whether this advance in the molt cycle reflects a hormetic toxic response, and/or an effect of a specific confounding factor that is neglected, or a limit of the model due to its calibration.…”

Active biomonitoring approaches are now recognized as relevant for monitoring water contamination and toxicity. Nevertheless, due to the confounding influence of variable and uncontrolled environmental conditions such as temperature, biological markers measured on transplanted individuals to assess water quality are difficult to interpret. The purpose of the present study is to propose a methodology for adapting a laboratory test of chronic sublethal toxicity based on the molting cycle of Gammarus fossarum to in situ assays. To this end, we 1) adapted the molt cycle temperature‐dependent model developed in Part 1 (Chaumot et al. 2020, this issue) to the fluctuating temperatures measured in the field; 2) assessed the predictive power of our approach as a “reference value” from gammarids caged in 9 nonimpacted sites at different seasons; and 3) tested the relevance of our tool to interpret in situ reproductive bioassays from 5 upstream/downstream studies and a large‐scale deployment in 12 sites. Our approach based on modeling the progress of gammarid molting cycle as a function of temperature appeared to be a relevant and robust tool for interpreting in situ observations in different environmental contexts in time and space. By avoiding using a “reference” or upstream situation as a baseline from which water quality could be assessed, this approach provides a real added value to water quality diagnosis in biomonitoring programs.
