  1. You state that the worms are effective at removing the heavy metals, I can see that is good for the sale and use of the compost for growing purposes.
    I assume that the worms have to be removed from the substrate for this to be effective? However, what is the impact on the subsequent food chain if the worms are utilized for feeding to other creatures?

    1. The food chain will not be affected as such because the worms when consumed by the other creatures will still add nutrient to the ecosystem when the creature removes waste products or dies

    The article indicates that the worms must be removed from the compost given that the toxic metals are bioaccumulated in their tissues. The worms cannot be consumed by other organisms otherwise they will suffer the fate of toxic metal poisoning.
    As someone who has done vermicomposting (I have had upwards of 20 compost bins working at one time), its a tedious task to separate the worms from the compost completely. I’d also like to know IF the young of these worms will be toxic prior to them leaving the egg? I’m guessing they will however given we haven’t a link to the research doc, we don’t know if this was looked at.

  3. @ Kathleen yeah i have noted your point and the angle you are coming from. sincerely i have looked at the possibility of the worms reproducing their first offsprings before taking part in bioremediation.
