    As I recall, a recent PBS special (maybe the one on poisons) indicated that bird eggs in contaminated areas contained up to fifty times the "lethal" human dose quantities of certain toxic chemicals (such as PCBs).

    And think of all the areas where health departments and other authorities discourage human consumption of fish.

      The damage from toxic spills and dumping can last a very long time --- and are very expensive to mitigate.

        to eradicate many toxins such as PCBs, dioxins and heavy metals like mercury and arsenic from soil or large volumes of water (lakes and oceans) because they filter out and sink to the bottom where they accumulate in the sediments. You would have to dredge the entire lake bottom, or ocean bottom to get rid of these toxins, and once they are dredged up, what do you do with the contaminated soil or sediment?  Persistent pesticides and other chemicals, especially petrochemicals are really impossible to get rid of. Once introduced into the environment, they remain forever.
