Sixty-four table grape samples from different regions of Tunisia were collected during three consecutive years (2015–2017). The presence of 96 pesticides, including dithiocarbamates, was assessed. Pesticides identification and quantification were performed by liquid or gas chromatography, coupled to tandem mass spectrometry. All samples contained multiple residues (4 to 24 residues), with an average of 11.6 residues per sample. Individual concentrations of pesticides in grapes ranged from 0.01 to 5.86 mg kg⁻¹. For at least one chemical compound, exceedances of the European Maximum Residue Limits were found in 94% of the samples. To assess the potential risk of pesticides through consumption of grapes, the acute exposure was estimated by the determination of predicted short term intake which is expressed as a percentage of Acute Reference Dose (ARfD), for non-compliances of pesticides. The exceedance of ARfD was associated with carbofuran, carbendazim, chlorpyrifos, deltamethrin, dimethoate and omethoate. Consequently, these pesticides could present a risk for consumer’s health.

连续三年（2015-2017年）收集了来自突尼斯不同地区的64杯葡萄样本。评估了包括二硫代氨基甲酸酯在内的96种农药的存在。农药的鉴定和定量是通过液相色谱或气相色谱联用质谱仪进行的。所有样品均含有多个残基（4至24个残基），每个样品平均含有11.6个残基。葡萄中农药的单独浓度范围为0.01至5.86 mg kg ^-1。对于至少一种化合物，在94％的样品中发现超过了欧洲最大残留限量。为了评估通过食用葡萄引起的农药潜在风险，通过确定预计短期摄入量来估计急性暴露量，该摄入量以不符合农药标准的急性参考剂量（ARfD）的百分比表示。超过ARfD的原因与呋喃丹，多菌灵，毒死rif，溴氰菊酯，乐果和氧化乐果有关。因此，这些农药可能会危害消费者的健康。
