摘　　要：用氟离子选择电极法按照国家标准GB7484—87《水质氟化物的测定》对570个稻谷样本进行含氟量的测定,计算重庆市每个区县的稻谷氟含量平均值并作曲线图;以稻谷氟污染与地域的关系、稻谷氟污染与水氟污染的关系及稻谷与玉米、小麦之间氟污染差异性进行t检验和方差分析。结果在重庆市38个区县中,平均含氟量超标的为15个,占39.47%,不超标的为23个,占60.53%;所采集样品氟含量全部超标的有铜梁、潼南、梁平、万州及沙坪坝5个区县,占13.16%,部分超标的有15个,占39.47%,不超标的有18个,占47.3%。其中,潼南氟污染较重,样品氟含量达1.96mg/kg,为辖区所有区县中最高。渝西各区县及主城区的稻谷氟含量较高,不同程度超过国家标准。The fluorine contents of 570 paddy samples were determined by electrode method for fluorine selection in accordance with the National Standard GB7484-87 'Water Quality Determination for Fluorine Content', on the basis of which the average value of the fluorine contained in the paddy grains produced in every district and county of Chongqing City was calculated and diagrammed. T's check and variance analysis were done to study the relationship between the fluorine pollution of paddy and the production origin, the relationship between the fluorine pollution of paddy and water pollution, and the difference between the fluorine pollution of paddy and that of corn and wheat. The results showed that in the 38 districts and counties of Chongqing City, 15 had an average fluorine content of paddy exceeding the standard, accounting for 39.47%, the rest 23 not exceeding the national standard, making up 60.53%; All the samples collected in such 5 districts and counties as Tongliang, Tongnan, Liangping, Wanzhou and Shapingba exceed the national standard. 15 districts and counties had part of their sample exceeding the standard, accounting for 39.47%. While the rest 18 not exceeding, making up 47.3%. In all the districts and counties Tongnan was the most serious one in fluorine pollution of paddy, the fluorine content reached up to 1.96 mg/kg. The districts and counties to the west of and adjacent to the city were serious, exceeded the national standard in varying degrees.
