Mercury poisoning

UWorld says that CaEDTA is the treatment of choice for lead and mercury poisoning.

I would have thought dimercaprol would be > CaEDTA for Hg-poisoning though, especially since FA, on p. 270, lists the Tx for hydrargyria as dimercaprol.

Any thoughts?

Chelation therapy for acute inorganic mercury poisoning can be done with DMSA, 2,3-dimercapto-1-propanesulfonic acid (DMPS), D-penicillamine (DPCN), or dimercaprol (BAL).[1] Only DMSA is FDA-approved for use in children for treating mercury poisoning. However, several studies found no clear clinical benefit from DMSA treatment for poisoning due to mercury vapor.[38] No chelator for methylmercury or ethylmercury is approved by the FDA; DMSA is the most frequently used for severe methylmercury poisoning, as it is given orally, has fewer side-effects, and has been found to be superior to BAL, DPCN, and DMPS.[1
