There has been a class action lawsuit filed in California against the people who bag the Ironite. Seems that it contains a bunch of heavy metals that are not listed. Here is a link that you can check out. Here are some figures for you. Note that these are levels that Ironite claims it contains: Arsenic4380 ppm
Lead 2910 ppm

Also check out this page for more info

Have fun.
