重庆市畜禽饮用水氟含量测定分析

DETERMINATION AND ANALYSIS ON THE CONTENTS OF FLUORINE IN DRINKING WATER FOR ANIMAL AND POULTRY ABOUT CHONGQING

为了全面了解重庆市畜禽饮用水氟含量分布状况,应用离子选择电极法对重庆市38个农业区县的570个畜禽饮用水样品进行了测定分析。结果表明,①重庆各区县畜禽饮用水中氟含量均未出现超标(国标1mg/L)现象,秀山、城口等13个地区畜禽饮用水甚至有严重低氟现象(<0.05mg/L);②重庆3大经济发展区其各区的整体均值均低于0.1mg/L,且三峡库区生态经济区平均含氟量显著低于都市发达经济区和渝西经济走廊(P<0.05)。

In order to investigate the contents of fluorine in drinking water for animal and poultry about Chongqing ,the 570 samples from 38 agricultural area were determined by fluorine selectrode analysis.The results showed that① The contents of fluorine in drinking water everwhere did not overtop the standard (GB:1 mg/L); thereinto,13 areas, such as Xiushan、Chengkou et.c, were lower (<0.05 mg/L).②Average contents of fluorine in dinking water for animal and poultry about three economy regions of Chongqing are under 0.1mg/L,and in which significantly lower than in metropolis flourishing economic districts and YUXI economic corridor ( P <0.05).
