Not really. You probably should avoid putting heavily polluted water through them though. They are the oceans waste buckets for poo water.
One of many reasons I don't eat shellfish.
Pollution easily kills shellfish. If anything, that’s an indication that they are clean and from clean places. Oysters feed of phytoplankton, not waste/garbage and pollution.

Shell fish is not to be harvested after storm water events due to the increased fecal matter/particulate content of rivers.
So I should be good.
