目的：了解杭州市居民膳食砷摄入情况，为开展相关膳食安全性评价提供依据。方法采用多阶段分层整群随机抽样方法抽取1744名居民并采用总膳食研究方法收集其食物消费量数据，在烹调后测定代表性混合食物样品中的总砷并推算无机砷含量，计算个体摄入量，与砷原每日最高容许摄入量（TDMI）和无机砷原暂定每周可耐受摄入量（PTWI）比较，分析其摄入水平。结果杭州市居民膳食总砷每日摄入量和由此推算的无机砷每周摄入量中位数分别为1．4和3．0μg／kgBW，占原 TDMI 的2．8％和原 PTWI 的20．2％；18岁以下组总砷每日摄入量和推算的无机砷每周摄入量中位数分别为1．6和3．5μg ／kgBW，均高于其他年龄组（Z ＝－7．577～－2．917，P 均＜0．01）；谷类食物对个体膳食砷摄入贡献率最高。结论杭州市居民膳食砷摄入量低于相关限值，但未成年人摄入量高于成人，应引起重视。
目的：瞭解杭州市居民膳食砷攝入情況，為開展相關膳食安全性評價提供依據。方法採用多階段分層整群隨機抽樣方法抽取1744名居民併採用總膳食研究方法收集其食物消費量數據，在烹調後測定代錶性混閤食物樣品中的總砷併推算無機砷含量，計算箇體攝入量，與砷原每日最高容許攝入量（TDMI）和無機砷原暫定每週可耐受攝入量（PTWI）比較，分析其攝入水平。結果杭州市居民膳食總砷每日攝入量和由此推算的無機砷每週攝入量中位數分彆為1．4和3．0μg／kgBW，佔原 TDMI 的2．8％和原 PTWI 的20．2％；18歲以下組總砷每日攝入量和推算的無機砷每週攝入量中位數分彆為1．6和3．5μg ／kgBW，均高于其他年齡組（Z ＝－7．577～－2．917，P 均＜0．01）；穀類食物對箇體膳食砷攝入貢獻率最高。結論杭州市居民膳食砷攝入量低于相關限值，但未成年人攝入量高于成人，應引起重視。

Objective To evaluate the dietary arsenic intake level among residents in Hangzhou city,and to provide scientific basis for further food safety assessment.Methods A stratified multi -stage cluster sampling method was performed,and a total of 1 744 subjects were enrolled.Total diet survey was conducted to collect food consumption data through both food -weighting and recording during 3 consecutive days.Representative mixed food samples were prepared for total arsenic (tAs)detecting by using inductively coupled plasma -mass spectrometry (ICP -MS).Daily tAs and weekly presumptive inorganic arsenic (p -inAs)intakes were calculated and compared with corresponding tolerable limit values.Results The medians of dietary tAs and p -inAs intakes were 1 .4 μg/kgbw/d and 3.0 μg/kgbw/week,which accounted for 2.8% and 20.2% of corresponding former TDMI /PTWI,respectively.The tAs and p -inAs intake (1 .6 μg/kg·bw/d and 3.5 μg/kg·bw/week,respectively)in the age group of <1 8 years were significantly higher than that of other age groups (Z =-7.577 ~-2.91 7,P <0.01 ).The mainly source of individual dietary arsenic intakes was cereal foods.Conclusion The dietary intake of tAs and p -inAs are safe,but more attention should be paid to juveniles for the dietary intakes of tAs and p -inAs .
