>I recently purchased the iron chelate mix from Homegrown Hydroponics and as
>the ingredients weren't listed on the container, I called them. It has the
>same ingredients and amounts that were in the Chelated Trace Element Mix
>that was mentioned on pg.9 of the Sears-Conlin report in the Krib at
>http://www.thekrib.com/Plants/Fertilizer/sears-conlin.html#pmdd  In addition
>to the EDTA as a chelator, it contains 0.5 -1.5% nitrilotriacetic. I have
>not heard this component mentioned before in the PMDD discussions before so
>I checked it out on the net. All references to it say that it is an iron
>chelate that is very carcinogenic to animals and humans causing kidney
>failures and other nasty conditions.One example of the sites I found is:
>http://ntpserver.niehs.nih.gov/htdocs/Levels/Tr006levels.Html There are many
>others stating the dangers of nitrilotriacetic acid. I'd be very grateful to
>hear from those who could tell me more on this.
