This innovative study was carried out to determine the presence of the mineral oil Arbofine in apple and soil at four locations. Arbofine kills the vast majority of dormant insects and mites (mite and asphid eggs, scales and psyllids) on fruit trees (cherry, apple, plum and peach) and thus reduces the plant diseases in summer. In this study, the mineral oil was sprayed at recommended doses of 2.0 and 0.75%, and the doses were doubled to 4.0 and 1.5% in dormant and summer seasons, respectively. The soil samples were taken for observation during the dormant season, whereas both soil and apple samples were taken during the summer season after treatment for 0, 1, 3 and 5 days. The recovery study of all the 11 paraffinic constituents (n-pentane, n-hexane, n-heptane, n-octane, n-nonane, n-decane, n-undecane, n-dodecane, n-tridecane, n-tetradecane and n-pentadecane) in soil and apple samples which constitutes 60% of mineral oil in soil and apple was carried out at the fortification level of 1.0 μg/ml, which was found to be between 72.1% and 99.0%. No residue of all the 11 paraffinic compounds of Arbofine mineral oil was detected in soil and apple samples at day 0 after the recommended doses, and the recommended doses were doubled in both seasons at four locations. Therefore, mineral oil can be used on apples without any risk.
本创新性研究旨在确定矿物油 Arbofine 在四个地点的苹果和土壤中的存在情况。Arbofine 可杀死绝大多数休眠期的昆虫和螨虫（螨和 asp 卵、鳞片和木虱），从而减少夏季果树（樱桃、苹果、李子和桃子）的植物病害。在这项研究中，矿物油按推荐剂量 2.0 和 0.75%喷洒，在休眠期和夏季，剂量分别加倍至 4.0 和 1.5%。在休眠期采集土壤样本进行观察，而在夏季处理后 0、1、3 和 5 天，分别采集土壤和苹果样本。对土壤和苹果样本中所有 11 种石蜡成分（正戊烷、正己烷、正庚烷、正辛烷、正壬烷、正癸烷、正十一烷、正十二烷、正十三烷、正十四烷和正十五烷）的回收研究，这些成分构成土壤和苹果中矿物油的 60%，在加标水平为 1.0μg/ml 时进行，结果发现回收率在 72.1%至 99.0%之间。在推荐剂量下，在推荐剂量下，在四个地点的两个季节中，土壤和苹果样本中均未检测到 Arbofine 矿物油的所有 11 种石蜡化合物的残留。因此，矿物油可安全地用于苹果。
