Heavy metal poisoning antidote for

Detoxication of Metals. Pectins or pectin derivatives have been proposed as antidotes for heavy metal poisoning for nearly 200 years. Kertesz (9) has reviewed the early work in this area. Pectin complexes lead so strongly as to quantitatively remove it from solution. Absorption 6f lead, arsenic, and selenium by several animal species has been reduced by pectin- or apple-containing diets. Use of pectin as a prophylactic agent in lead poisoning continues to be of interest. Bondarev (88) recently reported an increase in excretion and a decrease in bone accumulation of lead when rats fed 6 mg/day of lead also received 72-432 mg/day of low ester pectin. Paskins-Hurlburt et al. (89) achieved an 87% decrease in lead absorption by pectate fed rats. These studies bear out the early observations of Fellenburg (see 9, p. 572), who concluded that pectin of decreased ester content would have an enhanced ability to complex metals.

B. The medical treatment of occupational toxic illness should follow the general principles outlined earlier in this section and in Sections I and II of this book. In particular, the use of specific antidotes should be undertaken in consultation with a regional poison control center ([800] 222-1222) or other specialists. This is particularly true before chelation therapy is initiated for heavy metal poisoning.

The first chelating agent developed as an antidote to a heavy metal poison was 2,3-dimereaptopropanol (dimercaprol, British Anti-Lewisite, BAL). Originally intended for use on victims of the arsenical vesicant poison gas Lewisite52, it has since proved efficacious in the treatment of antimony, gold and mercury poisoning as well as...
