The residue levels of trichlorfon, fenthion and its metabolites were determined in olives, olive oil and vegetation water after treatment of olive trees at different times before harvest. The highest residues of fenthion were detected in oil, while the highest level of trichlorfon was found in vegetation water. The time gap between treatment and harvest strongly influences the residue levels of fenthion in olives and olive products. The levels of fenthion, which were lower than the maximum residue level (MRL) established by the Italian regulations, were obtained only when the treatment was carried out 60 days before harvest, so it may be necessary to use the insecticide trichlorfon 30 or 10 days before harvest since it leaves low residue levels in oils.
在收获前不同时间对橄榄树进行处理后,测定了橄榄、橄榄油和植被水中敌百虫、倍硫磷及其代谢物的残留水平。在油中检测到倍硫磷的残留量最高,而在植被水中发现敌百虫的含量最高。处理与收获之间的时间间隔对橄榄和橄榄产品中倍硫磷的残留水平有很大影响。只有在收获前60天进行处理时,倍硫磷的含量才低于意大利法规规定的最大残留限量(MRL),因此可能有必要在收获前30天或10天使用杀虫剂敌百虫,因为它在油中的残留量较低。
