Aetiology of endemic goitre:
iodine in Zambian waters, by J.N. Nwankwo, Zambia Journal of Science
and Technology, Vol.3, no.1, January 1978, Pg. 1-4
A detailed survey of iodine in Zambian waters revealed that most water have less
than 10 mg l-/l. This fact, together with the presence of goitrogens in the
local diet, could partially explain the prevalence of endemic goitre in Zambia.
There appears to be no established correlation between water hardness and iodine
concentration. The analytical technique used for the investigation was found to
have a recovery of 96.10% for iodine concentrations ranging from 0-50 mg/l, with
a coefficient of variation of ± 74%.
