Abstract/ Executive Summary:

Results of the present study indicated that iodine content of soil and drinking water of a sea side area are respectively 99.4 µg per 100g and 29.1 µg per litre. In the case of soil and water samples from plain lands, the iodine contents are one third to one fourth than that of sea side area samples, In the sea side area almost all category of foodstuffs were found to contain higher amount of iodine than that of plain lands. Irrespective of their origin the range of iodine content in Bangladeshi foodstuffs were, cereal: 2.5-4.3, vegetables: 0.7-17.2; fruits: 0.1-10.0 µg/100 gm. Fresh marine fishes were found to contain iodine in the range of 55.4-16S.0 µg/100 gm (mean 104.5 µg/100 gm). On the other hand, range of iodine content of fresh water fishes was only 1.7-22.4 µg/100 gm (mean 11. 2 µg/100 gm).

Objectives:

This study was the first attempt to compare the iodine content in the foodstuffs, soil and water from topographically two different areas, sea side area and plain land.

Methodology:

Teknaf is a peninsula, situated to the south eastern tip of Bangladesh was selected as the sea side area. Marine fishes were purchased in fresh condition from Teknaf local market and were brought to the Institute of Nutrition and Food Science, Dhaka University on the same day in a cold carrier. Other food items were also procured in fresh condition from local households and market of Teknaf. Soil and water samples of sea side area were also collected from Teknaf. All the samples were kept in- 20⁰C till laboratory analysis. Plain land foods were purchased from different local markets of Dhaka city. Soil and water samples of plain land were collected from Dholaikhal area of Dhaka city. Small amounts of tolune was added to every water sample to form a thin layer, which protected the samples from the formation of microorganisms. In all cases, the samples were analyzed in the laboratory as early as possible after collection. Iodine in soil and foodstuffs were determined following the procedure described by He nry+. Iodine estimation in water was done following the method described by Karrnarkar et. al.
