ABSTRACT
Objective To evaluate the effect of endemic disease prevention in Shaanxi province caused by earthquake and supply a scientific basis for making decision regarding restoration and reconstruction after the earthquake.Methods Forty different drinking water samples were collected respectively from Mianxian county and Chencang district the earthquakes'most severely hit areas in Shaanxi province with drinking-water-borne fluorosis.The contents of fluorine and arsenic in the water was detected by Fluoride ion-selective electrode and hydride generation atomic fluorescence spectrometry,respectively.Two hundreds iodized salt and urine samples were collected from affected household women aged 18-45 in severely hit Ningqiang and Lveyang countie with iodine deficiency disorders.The contents of iodine in the salt was detected by semi-quantitative and of urinary iodine of household women was determined by AsⅢ-Ce4+ catalytic spectrophotometry.Two hundred children aged 7-12 were detected by clinical and X-ray examination from Ningqiang and Lveyang counties of Kashin-Beck disease prevailing areas.Hair and food samples from 20 children were collected.The contents of selenium were determined by 2,3-Diamino naphthalene fluorescence spectrophotometry and of T-2 toxin in the food was detected by ELISA.Results No incidents of serious hydrologieM or geological damage were found.Fluoride content in one of eighty water samples was beyond 1.5 mg/L,accounting for 1.25%;five samples were between 1.0 mg/L and 1.5 mg/L,accounting for 6.25%the arsenic content of all samples were below 0.01 mg/L;all the salt samples from the home of household aged 18-45 were iodine salt,the median of urine iodine of household wonlen Was 303.03μg/L (21.40-1133.54 μg/L) and 325.21 μg/L(27.61 - 1191.46 μg,/L) in Ningqiang and Lveyang counties, respectively.No clinical and X-ray patients were found in the children aged 7 - 12, the average content of selenium in hair was (0.2638 ± 0.0875)mg/kg; the content of T-2 toxin in the forty food samples was below 100 μg/kg. Conclusions The prevention of the endemic disease in the four counties has been moderately affected by the earthquake, but the situation of endemic disease is stable and there is no evidence of the endemic disease.
