Several models have been developed for a kinetic approach to bioaccumulation that would model the trophic transfer of contaminant in animals from ingested food. A first-order kinetic model has been proposed, which considers uptake from both dissolved and particulate phases [95], A particular application of that model is to separate the pathways for metal uptake in marine suspension and deposit feeders since ... 

The marine amphipod Ampelisca abdita is a suspension and deposit feeder and it often occurs as a numerically dominant member of benthic communities (Fay et al., 2000). It can also serve as an important food source for bottom-feeding fish. 4-nonylphenol is a degradation product from detergents (see Fig. 2.16). Its relevant physical-chemical properties are given in Appendix C.

Discrepancies between the types of MAAs found in algae (or other food sources such as sediments for deposit feeders) and animals from the same region have been observed in a number of studies.104 107 112 123 130 154 156 Even when the MAAs in primary producers and consumers are the same, the relative concentrations often are not. At present, the commonly accepted explanation for such differences is that intestinal microflora or animal enzymes are facilitating interconversions among various MAAs.14 101 -103-156...
