DMPS chelates both mercury and lead

I am a bit confused now. I did see that DMPS chelates Lead but in other messages I read that it doesn't in any effective amount.

Then I read that DMSA also does very little for Lead when using the standard low dose. I can vouch for that, have been spiking to as high as 3mg/lbs every 8-12 hours to effectively remove lead.

NOTE: Also one really needs to sort on date when searching for stuff, some later message (2006): http://onibasu.com/archives/am/171043.html
