I assume bio accumulation would be a larger factor. Especially for compounds containing Hg.

I requested and received a chemical and metals analysis from our local water association about 4 years ago. I was surprised to find trace levels, (ppm) of chromium, lead, mercury, molybdenum, arsenic and other chemicals in our drinking water. Several of these chemicals are water treatment chemicals and are definitely harmful at some level. I called the Association to ask how chromium was in our drinking water but no one seemed to know much. We drink a lot of bottled water now.

Mercury and PCB's are the most concerning but if you look at a list of the highest level of those you will not see catfish there. The larger fish (I.e. tuna) are of greater concern due to bioaccumulation. Basically, the larger fish eat smaller fish and contaminates become concentrated in the larger fish. Also, while pesticides are concerning, the mississippi river simply has a tremendous volume of flow and dilutes whatever contaminates there may be. Here is a list LINK
