There are no heavy metals detectable in commercial fish oils (for an example of such analysis, you can go to www.consumerlab.com).
The reason has nothing to do with cheap, or purification. It's a purely physico-chemical outome; metal ions are not fat-soluble. The contaminants in fish oil are likely to be the fat-soluble organic chemicals, like DDT and PCBs. There's already a thread on that topic.
Mercury, lead, and other heavy metals bind powerfully to protein. That's one of the reasons they're so toxic. Enzymes are protein structures, and they don't work well (or at all) if they're associated with heavy metals.
Fish meat has heavy metals in it (but so does cow). Fish oil has none.
