Both zebra mussels and round gobies can transfer Polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes (PCNs) in the food chain from lower- to higher-trophic level organisms. However, no significant biomagnification occurred between these two species.

The levels of polynuclear aromatic hydrocarbons in benthic fish was not attributed to the ingestion of contaminated biota such as zebra mussels.

Zebra mussels were predicted to bioaccumulate PCBs. As a result many other organisms were predicted to have increased PCB levels as well.

Zebra mussels showed significantly higher levels of PCB contamination than native mussels. Zebra mussels are capable of altering contaminant dynamics of the benthos.

"Dreissena represents a much larger contaminant pool than native mussels. The studies suggest that Dreissena, where it has become a dominant part of the benthos will substantially alter contaminant dynamics.

Biomagnification of polychlorinated biphenyls (PCBs) was observed in Gammarus amphipods associated with zebra mussels (Dreissena polymorpha), indicating concentration of pollutants in zebra mussel feces or pseudofeces can transfer to other trophic levels.

Biomagnification of toxic contaminants through the food web is another concern of zebra mussel invasion, especially because mussel predation by round goby (Neogobius melanostomus) has provided a link between Dreissena and higher trophic levels.

Declines in Diporeia spp., another benthic invertebrate, have been highly correlated with dreissenid expansion, potentially due to reductions in phytoplankton abundance (an important food source) or through the introduction of toxins and pathogens associated with dreissenids and their waste products.

Like other mollusks, Dreissena polymorpha is capable of hosting a variety of parasites, although the parasite load varies across its introduced range and appears to be lower in North America.

In particular, Dreissena polymorpha acts as an intermediate host of the trematode Bucephalus polymorphus, which has caused pathologies and mortalities in cyprinids across parts of Europe.
