I haven't read any of the studies you refer to, but be careful about accepting studies which are sited by companies to sell their products. Studies can be manipulated to say whatever the company wants them to.
I suggest that you look around this site to see how people successfully removed metals. A lot of people have been helped by the Cutler Protocol. For me I began feeling much better after using a combination of Cilantro/Chlorella and the Cutler Protocol.
