Unanswered questions : iodine in agricultural crops

Iodine in fruit and vegetables contributes to the total iodine intake of the population. While iodine is not an essential element for plant growth and does not contribute to plant functioning, it can be taken up by plants from the soil environment and accumulates in plant tissue. The concentration of iodine in common fruit and vegetable crops in Tasmania has not been examined, so the contribution to dietary intake while likely to be small is unknown. The ability to accumulate nutrients varies between plant species, so we would expect differences in iodine concentration to exist between the various fruit and vegetables grown in Tasmania.
