This study quantitatively measured neonicotinoids in various foods that are common to human consumption. All fruit and vegetable samples (except nectarine and tomato) and 90% of honey samples were detected positive for at least one neonicotinoid; 72% of fruits, 45% of vegetables, and 50% of honey samples contained at least two different neonicotinoids in one sample, with imidacloprid having the highest detection rate among all samples. All pollen samples from New Zealand contained multiple neonicotinoids, and five of seven pollens from Massachusetts detected positive for imidacloprid. These results show the prevalence of low-level neonicotinoid residues in fruits, vegetables, and honey that are readily available in the market for human consumption and in the environment where honeybees forage. In light of new reports of toxicological effects in mammals, the results strengthen the importance of assessing dietary neonicotinoid intakes and the potential human health effects.
本研究对人类日常食用的各类食物中的新烟碱类物质进行了定量测定。所有水果和蔬菜样本（油桃和番茄除外）以及90%的蜂蜜样本至少检测出一种新烟碱类物质呈阳性；72%的水果样本、45%的蔬菜样本和50%的蜂蜜样本在一个样本中至少含有两种不同的新烟碱类物质，其中吡虫啉在所有样本中的检出率最高。来自新西兰的所有花粉样本都含有多种新烟碱类物质，来自马萨诸塞州的7份花粉样本中有5份检测出吡虫啉呈阳性。这些结果表明，在市场上供人类食用的水果、蔬菜和蜂蜜以及蜜蜂觅食的环境中，低水平新烟碱类残留物普遍存在。鉴于有关哺乳动物毒理学效应的新报告，这些结果强化了评估膳食中烟碱类物质摄入量及其对人类健康潜在影响的重要性。
