Abstract:
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 .
