Dietary exposure to pesticide residues was assessed in Yaoundé, Cameroon, using the total diet study (TDS) method. Sixty-three composite samples, representative of the foods as consumed in Yaoundé, were collected, prepared, and analysed for residues of pesticides including organochlorine, organophosphorous, and pyrethroids. A multi-residue method was used with a limit of detection (LOD) of 0.005 mg kg(-1). Additional analyses were performed for dithiocarbamates (LOD=0.050 mg kg(-1)), glyphosate (LOD=0.005 mg kg(-1)) and chlordecone (LOD=0.0008 mg kg(-1)) on certain composites samples. The overall contamination was low with 37 out of 46 pesticides below the LOD in all samples. The estimated upper bound (for values less than the LOD equal the LOD; and values less than the LOQ equal the LOQ) of the mean dietary exposures ranged from 0.24% (cypermethrin) to 3.03% (pirimiphos-methyl) of the acceptable daily intakes (ADIs) for pesticides for which at least one analysis was greater than the LOD. This study suggests a low dietary exposure to pesticide residues in Yaoundé.
在喀麦隆雅温得，采用总膳食研究（TDS）方法评估了膳食中农药残留的暴露情况。采集了63个能代表雅温得市消费食品的混合样本，进行制备并分析其中有机氯、有机磷和拟除虫菊酯等农药的残留。采用多残留方法，检测限（LOD）为0.005 mg kg⁻¹。对某些混合样本还进行了二硫代氨基甲酸盐（LOD = 0.050 mg kg⁻¹）、草甘膦（LOD = 0.005 mg kg⁻¹）和十氯酮（LOD = 0.0008 mg kg⁻¹）的额外分析。总体污染程度较低，所有样本中46种农药中有37种低于检测限。对于至少有一次分析结果高于检测限的农药，估计的平均膳食暴露上限（低于检测限的值等于检测限；低于定量限的值等于定量限）占农药每日允许摄入量（ADI）的0.24%（氯氰菊酯）至3.03%（甲基嘧啶磷）。该研究表明，雅温得市膳食中农药残留的暴露水平较低。
