From memory, it depends on the toxin.

Heavy metals or things that aren't biologically eliminated accumulate as you go up the food chain.

That is true. The heavy metal parts was a miss recollection. Toxins from run-offs, contaminated water, and algal blooms are the main problems.

Because filter feeders are generally low on the food chain, they are actually a food type which is very low on heavy metals. Thanks for correcting me.
