本文报道,用亚砷酸铈比色计对1993年罗马某犊牛暴发先天性甲状腺肿地区的井水和饮水作了进二步探讨。发现水的含碘量低于5μg/Litre。该地区约40％的儿童发生碘缺乏症,一些成人罹患甲状腺肿。经改善供水系统后,该地区的发病率有所下降。
This paper reports the use of a cerium arsenite colorimeter to investigate the well and drinking water of a congenital goiter outbreak in a Roman calf in 1993. The iodine content of the water was found to be below 5 μg / Liter. About 40% of children in the area develop iodine deficiency and some adults have goitre. After the improvement of the water supply system, the incidence of the area has declined.
