Determination Of Iodine Content Of Household Salts In The Area Of Srimangal In Bangladesh

Abstract

IDD (Iodine deficiency disorders) are recognized as a major global public health problem. Insufficient iodine intake was observed in about 2.5 billion people worldwide. Among them 313 million are from South-eastern Asian region including Bangladesh. Many people suffers from IDD in Bangladesh. To ensure adequate iodine intake, salt iodinization is an effective strategy which is safe, sustainable and cost-effective as well. The objective of the study was to determine the iodine concentration of household salts collected from 20 households of tea plantation worker from Srimangal area of Bangladesh. Concentration of iodine in salt was determined by iodometric titration method. Reagent was K2Cr2O7, standardized Na2S2O3, KI, NaHCO3, starch, concentrated HCl, H2SO4. According to WHO guidline the acceptable range of iodine content of salt is 20-50 ppm. Out of 20 samples, 7 did not show the iodine content within the standard range. Evidence is now available from both controlled trials and successful iodization programs that IDD disorders can be successfully prevented by correction of iodine deficiency. Inadequate iodine fortification in correcting & preventing IDD still persists in household in Srimangal area. Appropiate measurement should be taken in salt iodinization in commercially available salts in Bangladesh.
