中文摘要：

目的了解我国西南地区新鲜辣椒中含氟量的分布规律，为确定新鲜辣椒中氟的污染判别值提供本底数据。方法自西南76个县市采集新鲜辣椒175个，按照《食品中氟的测定》（GB／T 5009．18-2003）方法进行含氟量测定，根据地区及辣椒品种，对辣椒中含氟量进行统计分析。结果新鲜辣椒干重含氟几何均数为8．9mg／kg。有95．54％的新鲜辣椒干重含氟量低于24．7ms／kg。结论我国现行的食品中氟限量低于1．0mg／kg的标准（GB2762—2005）可能不适用于辣椒，需要确定新鲜辣椒中氟的污染判别标准。

英文摘要：

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.
