TK interactions between metals and organic compounds are also possible phenan-threne appears to enhance the uptake of cadmium from sediment in the amphipod Hyalella azteca (Gust and Fleeger 2005). In the same species, chlorpyrifos enhances the accumulation of methyl mercury, but methyl mercury reduces acetylcholinesterase inhibition caused by chlorpyrifos, presumably due to the formation of a chlor-pyrifos-MeHg complex (Steevens and Benson 1999).

Acute toxicity values (LC50) for freshwater organisms ranged from 55.7pgH for the amphipod Hyalella azteca) to 774 pgH for the snail Phy-sella virgata). No relationships have been demonstrated between water quality characteristics (such as hardness and pH) and toxicity. The freshwater final acute value (FAV) for NP is 55.7pgl which is equal to the LC50 for the most sensitive tested... 

Although the toxicity of DDT to the amphipod Hyalella azteca decreased with increasing carbon content of the sediment, this was not the case for endrin (Nebeker et al. 1989) so that specific mechanisms of interaction even between neutral xenobiotics and the organic carbon in the sediment phase may be of determinative significance. The results with DDT are, in fact, consistent with evidence from equilibrium dialysis experiments of its association with dissolved humic material (Carter and Suffet 1982).
