  The good news, engineers at Northwestern University now report, is
that even in heavily lead-tainted dirt, most of the metal usually
becomes trapped in the parts of plants that few people eat, such as
roots and stems. Indeed, the new data indicate that intentionally using
inedible plants to sop up lead could prove a low-cost strategy for
detoxifying backyards and school grounds, making them safer for
children.


Lawrence--  Help us out here. What are the names of some grasses that are good for sequestering heavy metals?

One fallow season growing these grasses and removing them, rather than turning them under, should clean up an urban garden and make it ready for veggies. The problem is what to do with the chaff. Take it to the landfill, if they will accept it, I suppose.
