【摘要】：[目的]比較仙游縣胃癌高、低發(fā)地區(qū)土壤、飲用水及大米中環(huán)境化學元素含量,了解它們的分布特征。[方法]課題組于2014年隨機抽取有代表性的胃癌高發(fā)鄉(xiāng)鎮(zhèn)7個,低發(fā)鄉(xiāng)鎮(zhèn)5個,每個鄉(xiāng)鎮(zhèn)各抽取2~3個村,進行土壤(99份樣本)、飲用水(99份樣本)、大米(53份樣本)的采樣,運用原子熒光光譜法測定各樣本的硒、砷、汞元素,采用電感耦合等離子體質譜法測定各樣本的鈣、鐵、鎂、錳、鈷、鎳、銅、鋅、鉬、鎘、鋇、鉛元素含量。分析胃癌高、低發(fā)地區(qū)土壤、飲用水、大米中化學元素的含量差異及其意義。[結果]胃癌高發(fā)區(qū)土壤中鈣、鎂含量中位數水平低于低發(fā)區(qū)(P0.05);飲用水中硒和砷未檢出,胃癌高發(fā)區(qū)飲用水中鈣、鎂、錳、鈷、鎳、鋇及鉛的質量濃度中位數水平低于低發(fā)區(qū)(P0.05);胃癌高發(fā)區(qū)大米中鉬含量的中位數水平和鋅銅比低于低發(fā)區(qū),而鎂、錳含量的中位數水平高于低發(fā)區(qū)(P0.05)。[結論]仙游縣胃癌高、低發(fā)區(qū)土壤、飲用水及大米中鈣、鎂等元素存在一定差異。
[Abstract]:[objective] to compare the contents of environmental chemical elements in soil, drinking water and rice in high and low incidence areas of gastric cancer in Xianyou County, and to understand their distribution characteristics. [methods] A sample of 99 soil samples, 99 samples of drinking water and 53 samples of rice were collected randomly from 7 representative towns with high incidence of gastric cancer and 5 villages with low incidence of gastric cancer in 2014. The elements of selenium, arsenic and mercury were determined by atomic fluorescence spectrometry. The contents of calcium, iron, magnesium, manganese, cobalt, nickel, copper, zinc, molybdenum, cadmium, barium and lead were determined by inductively coupled plasma mass spectrometry. The difference and significance of chemical elements in soil, drinking water and rice in high and low incidence areas of gastric cancer were analyzed. [results] the median level of calcium and magnesium in the soil of the high incidence area of gastric cancer was lower than that in the low incidence area (P 0.05), the selenium and arsenic in drinking water were not detected, and the contents of calcium, magnesium, manganese, cobalt, nickel in drinking water of the high incidence area of gastric cancer were not detected. The median level of mass concentration of barium and lead was lower than that of low incidence area (P 0.05), the median level of Mo content and Zn / Cu ratio of rice in high incidence area of gastric cancer was lower than that of low incidence area, while the median level of magnesium and manganese content was higher than that of low incidence area (P 0.05). [conclusion] there are some differences in calcium and magnesium in soil, drinking water and rice in Xianyou County.
