对新疆重点加碘企业的盐碘质量进行了现况调查，在１６个盐厂中加碘浓度在５０ｍｇ／ｋｇ以上的企业有３个（１８．７５％），４０～４９ｍｇ／ｋｇ的有８个（５０．００％），３９ｍｇ／ｋｇ以下的有５个（３１．２５％）；加入不同浓度碘的均值水平比较有显著性差异（Ｐ＜０．０１）；在本次抽检的４５０份样品中，合格的（＞４０ｍｇ／ｋｇ）２０５份（４５．５６％），不合格的２４５份（５４．４４％），其碘盐合格率随碘的加入量增大而增高，按５０、４０～４９和＜３９ｍｇ／ｋｇ３个浓度级加入碘的合格率依次为６７．００％、５４．２２％、１２．８０％，碘盐合格率与加碘浓度呈正相关（ｒ＝０．９７０５）。并对今后如何提高新疆碘盐生产的质量提出了建议和意见。
Salt iodine quality in key iodized enterprises in Xinjiang was investigated. Three companies (18.75%) with iodine concentration above 50 mg / kg in 16 salt factories and 8 (40-49 mg / kg) (50.00%), 5 (31.25%) under 39mg / kg; the average level of iodine added with different concentrations was significantly different (P <0.01); in the sampling of 450 Among the samples, 205 (45.56%) of qualified (> 40mg / kg) and 245 (54.44%) of unqualified ones had the qualification rate of iodized salt increasing with the increasing of iodine. The pass rates of adding iodine in 40 ~ 49 and <39mg / kg concentration levels were 67.00%, 54.22% and 12.80%, respectively. The passing rate of iodized salt was positively correlated with iodine concentration (r = 0.9705) . And put forward suggestions and opinions on how to improve the quality of iodized salt production in Xinjiang in the future.
