Introduction. Iodine deficiency early in life can irreversibly impair neurodevelopment and increase infant mortality (1).Iodine is needed for the production of thyroid hormone, which is essential for normal physical and neurologic growth and maturation in the first 2 y of life (2., 3., 4pared with other age groups, infants are …Web

For the same amount of iodine release, there is a higher surface deposition of elemental iodine (I 2) because it has a higher dry deposition velocity, while the air concentration of a representative organic iodide (CH 3 I) is higher due to its lower dry deposition velocity, which means a lower depletion of the air concentration. Despite ...Web
