“…Their study asserted that bioaccumulation factors (BAF) signify different rates of bioconcentrations for various aquatic organisms in Baiyangdian Lake. In addition, Rashleigh et al (2009) applied AQUATOX to better characterize food web dynamics, which led to PCB biomagnification in Lake Hartwell. Their study reported on a dominant PCB pathway that led from detritus to daphnia to shad to largemouth bass.…”

“…The model has been widely applied by researchers. It has been used to ecologically assess pesticides in an Iowa reservoir (Mauriello and Park, 2002); fish dynamics in a North Carolina stream (Rashleigh, 2003); nutrients and suspended sediments in a Minnesota river (Carleton et al, 2005;Park et al, 2005); polychlorinated biphenyl (PCB) contamination in a Georgia reservoir (Rashleigh et al, 2005;Rashleigh, 2007); dynamic calibration and validation related to periphyton and zoobenthos in experimental streams in France (Sourisseau et al, 2008); nitrobenzene content in Songhua River (Lei et al, 2008;Wang et al, 2012); PCB contamination in Lake Hartwell (Rashleigh et al, 2009); TCE risk in a stream in Lille Skensved, Denmark (McKnight et al, 2010); and nutrient content in Lake Erhai (Chen et al, 2012). AQUATOX has been applied to streams, ponds, lakes, estuaries, reservoirs, and experimental enclosures.…”

Ecological production functions (EPFs) link ecosystems, stressors, and management actions to ecosystem services (ES) production. Although EPFs are acknowledged as being essential to improve environmental management, their use in ecological risk assessment has received relatively little attention. Ecological production functions may be defined as usable expressions (i.e., models) of the processes by which ecosystems produce ES, often including external influences on those processes. We identify key attributes of EPFs and discuss both actual and idealized examples of their use to inform decision making. Whenever possible, EPFs should estimate final, rather than intermediate, ES. Although various types of EPFs have been developed, we suggest that EPFs are more useful for decision making if they quantify ES outcomes, respond to ecosystem condition, respond to stressor levels or management scenarios, reflect ecological complexity, rely on data with broad coverage, have performed well previously, are practical to use, and are open and transparent. In an example using pesticides, we illustrate how EPFs with these attributes could enable the inclusion of ES in ecological risk assessment. The biggest challenges to ES inclusion are limited data sets that are easily adapted for use in modeling EPFs and generally poor understanding of linkages among ecological components and the processes that ultimately deliver the ES. We conclude by advocating for the incorporation into EPFs of added ecological complexity and greater ability to represent the trade-offs among ES.

“…The number of possible interactions and the level of detail in those, results in more than 450 equations that are implemented in the model source code. Applications of AQUATOX to case studies do exist in literature (Rashleigh ; Sourisseau et al ; Rashleigh et al ) but the effort for the definition of state variables, parameter calibration, and model analysis appears large in comparison with the precision of the outcome. The use of AQUATOX results for the ERA of chemicals is especially impaired by the uncertainty associated with model extrapolations.…”

This article presents a framework to diagnose and predict the effects of chemicals, integrating 2 promising tools to incorporate more ecology into ecological risk assessment, namely traits-based approaches and ecological modeling. Traits-based approaches are used increasingly to derive correlations between the occurrence of species traits and chemical exposure from biological and chemical monitoring data. This assessment can also be used in a diagnostic way, i.e., to identify the chemicals probably posing the highest risks to the aquatic ecosystems. The article also describes how ecological models can be used to explore how traits govern the species-substance interactions and to predict effects at the individual, population, and community and ecosystem level, i.e., from the receptor to the landscape level. This can be done by developing models describing the toxicokinetics and toxicodynamics of the chemical in the individual, the life-history of species and the connectivity of populations, determining their recovery, and the food web relations at the community and ecosystem level that determine the indirect effects. Special attention is given on how spatial aspects can be included in the ecological risk assessments using ecological models. The components of the framework are introduced and critically discussed. We describe how the different tools and data generated through experimentation (laboratory and semifield) and biomonitoring can be integrated. The article uses examples from the aquatic compartment, but the concepts that are used, and their integration within the framework, can be generalized to other environmental compartments.
