Little is known, however, about risk assessment for groundwater As contamination of fish in the polyculture systems. In this study, we assess milkfish and tilapia exposure risks to waterborne As in the polyculture ponds using a model-based risk assessment framework.he essential toxicokinetic parameter estimates for milkfish and tilapia were listed in Table 1. A first-order kinetic model was used to optimally fit the published data to obtain the exchange rates between water and sediment of k w and k s (Table 1; Fig. 2 A and B).
