通过田间试验研究了乙酰甲胺磷和噻嗪酮在橄榄上的残留。两个品种，pizz'e carroga和pendolino，分别与非常大和小的水果。处理后，没有发现两种农药沉积在橄榄上的差异。两种农药的消失率（以假一级动力学计算）相似（平均12天）。所有橄榄中都含有乙酰甲胺磷的代谢物甲胺磷，在一些pendolino样本中，甲胺磷的残留量高于最大残留限量。在橄榄加工的第一步清洗过程中，橄榄上两种农药的残留量并没有减少。在橄榄加工成油后，在橄榄油中没有发现乙酰甲胺磷或甲胺磷的残留物，而噻嗪酮的残留物平均比橄榄高四倍。
Field trials were carried out to study the persistence of acephate and buprofezin on olives. Two cultivars, pizz'e carroga and pendolino, with very large and small fruits respectively were used. After treatment, no difference was found between the two pesticide deposits on the olives. The disappearance rates, calculated as pseudo first order kinetics, were similar for both pesticides (on average 12 days). Methamidophos, the acephate metabolite, was always present on all olives, and in some pendolino samples it showed higher residues than the maximum residue limit (MRL). During washing, the first step of olive processing, the residue level of both pesticides on the olives did not decrease. After processing of the olives into oil, no residues of acephate or methamidophos were found in the olive oil, while the residues of buprofezin were on average four times higher than on olives.
