【摘要】：目的调查分析华中某省农村重金属污染区域妇女膳食中的镉暴露水平。方法在华中某省16个农村重金属污染区域采集当地产的大米及其制品、叶菜类蔬菜、块根类蔬菜、瓜果类蔬菜、鲜豆类蔬菜、茄果类蔬菜、猪肉和鱼8类食物共384份样品,采用石墨炉原子吸收光谱法测定食物中的镉含量;采用半定量食物频率问卷获得当地妇女这8类食物的消费量,比照镉的暂定每月可耐受摄入量(PTMI),初步评估当地妇女膳食中的镉暴露的安全性。结果 8类食物中,大米及其制品的镉的平均含量最高(86.784μg/kg),其次为茄果类蔬菜(64.060μg/kg),猪肉的镉平均含量最低(4.862μg/kg)。当地妇女镉的平均每月暴露量为22.394μg/kg BW,占PTMI的89.18%,膳食中的镉每月暴露量的P90为53.929μg/kg BW,占PTMI的224.27%。大米及其制品对膳食中的镉暴露量的贡献率最高(67.52%)。结论该省农村重金属污染区域妇女膳食中的镉暴露量处于较高水平,且有一定比例的个体镉暴露量超标,食物中大米及其制品对镉暴露的贡献率最高。
[Abstract]:Objective to investigate and analyze the level of cadmium exposure in diet of women in a rural heavy metal polluted area in central China. Methods Rice and its products and vegetables were collected from 16 rural heavy metal polluted areas in central China province. There were 384 samples of root vegetable, melon and fruit vegetable, fresh bean vegetable, eggplant vegetable, pork and fish. The content of cadmium in food was determined by graphite furnace atomic absorption spectrometry (GFAAS). A semi-quantitative food frequency questionnaire was used to obtain the consumption of the 8 kinds of food in local women, and compared with the tentative monthly tolerable intake of cadmium (PTMII). Results the average content of cadmium in rice and its products was the highest (86.784 渭 g / kg). The next was eggplant vegetables (64.060 渭 g / kg). The average cadmium content of pork was the lowest (4.862 渭 g / kg 路kg ~ (-1)). The average monthly exposure of cadmium in local women was 22.394 渭 g / kg BW, accounting for 89.18% of PTMI. The monthly exposure P90 of cadmium in diet was 53.929 渭 g / kg BW. The contribution of rice and its products to cadmium exposure in diet is the highest (67.52%). Conclusion the level of cadmium exposure in the diet of women in the rural areas contaminated by heavy metals in this province is at a high level. A certain proportion of individual cadmium exposure exceeded the standard, and the contribution rate of rice and its products to cadmium exposure was the highest.
