I understand that mustard plants can be used to soak up toxins, such as
lead, from the soil.  The plants are then destroyed and not composted of
course.  It is alo my understanding that fruit in general does not
absorb toxins readily from the soil and thus can be planted safely in
such areas.

What other plants can be used to absorb toxins, and what other plants
are safe to plant and eat from in such areas?
