Other Pb-chelating agents [Ca[Na.sub.2]EDTA, citrate, penicillamine, and 2,3-dimercapto-1-propanol, also known as
British AntiLewisite (BAL)] have been shown to increase GI Pb absorption, and in some cases (citrate, penicillamine, and BAL) this has resulted in an increase in body Pb burden (11).
Despite chelation therapy with
British antilewisite and calcium disodium edetate (CaNa[sub.2]-EDTA), the child developed seizures, became comatose, and died 26 hours after admission.
