After more than ten years since pesticide residues were detected in citrus-flavored soft drinks, this study reveals that the situation has not changed. A new sensitive multiresidue UHPLC-MS/MS method has been validated for 88 pesticides, which was used to analyze 200 samples manufactured in 67 countries, 80% corresponding to fruit-based soft drinks. The results show that 98% of the samples collected worldwide contained at least one pesticide, and 85% of them contained more than 4 pesticides. 40 out of 88 target compounds were quantified among the screened samples. Europe was the world region with the highest total amount of pesticides, probably due to the higher content of juice concentrate in samples, which may be the main source of the pesticide residues. Nevertheless, residues were also found in samples with no juice, so water quality also plays an important role as the main ingredient of citrus-flavored soft drinks.
在检测到柑橘味软饮料中含有农药残留的十多年后，本研究表明情况并未改变。已经验证了一种新的用于分析 67 个国家生产的 200 个样本的、针对 88 种农药的灵敏的多残留 UHPLC-MS/MS 方法，80%的样本对应的是水果味软饮料。结果表明，全球采集的 98%的样本至少含有一种农药，85%的样本含有超过 4 种农药。在所筛选的样本中，定量分析了 88 种目标化合物中的 40 种。欧洲是世界上农药总量最高的地区，这可能是由于样本中浓缩果汁含量较高，这可能是农药残留的主要来源。然而，在不含果汁的样本中也发现了残留，因此水质作为柑橘味软饮料的主要成分也起着重要作用。
