Urine samples were collected from 1,064 pupils aged 8 to 10 in primary school in Urumqi, urinary iodine was determined by arsenic and cerium catalytic spectrophotometry. Results A total of 1 064 urine samples were detected during 1999-2004. The median urinary iodine was 242.94 μg / L, with a median of 284.18 μg / L in 1999 and a median of 232.63 μg / L in 2002. The median was 212.02 μg / L.
