An initial research of fluoride content distribution in fresh chilies in the southwest of China / 中国地方病学杂志

ABSTRACT

Objective To investigate the distribution of fluoride content in fresh chili in southwestern China and provide the fluoride background content for the confirming fluoride contamination discrimination value for fresh chili.Methods The method of analyzing fluoride in food as stipulated in GB/T 5009.18-2003 was adopted to determinate fluoride content in chilies.175 fresh chili samples were collected from 76 counties in southwestern China.Based on the origin and types of the chilies,we systemically analyzed the fluoride content in fresh chilies.Results In fresh chilies directly sampled from farms,the averaging content was up to 8.9 mg/kg(dry weight)and the fluoride content in more than 95.54% of fresh chili samples was less than 24.7 mg/kg(dry weight).Conclusions The current fluoride content standard for vegetables as stipulated in GB 2762-2005(≤1.0 mg/kg)is unsuitable for chili,therefore it is essential to draw a new value for discriminating fluoride contamination in fresh chili.
