Between 1978 and 1986, 305 samples of apples were monitored for the residues of a wide range of pesticides used in their production. Three (1%) contained residues above the maximum residue limits (MRL) permitted under the Canadian Food and Drug Act and regulations; two involved phosalone at 5.9 and 6.2 mg/kg respectively and one involved diphenylamine at 6.7 mg/kg when the MRL was 5.0 mg/kg for both compounds. Low residues of dicofol, endosulfan, phosalone, phosmet, captan, daminozide and diphenylamine were frequently found; however they were well below the MRLs. These residue levels were correlated with survey data on the areas of the apple crop treated with specific pesticides. Residues of carbaryl, diazinon, ethion, azinophosmethyl, parathion, and dithiocarbamate fungicides were found occasionally; all were well below the MRLs and correlated with the pattern of use. No residues of PCB were found to a limit of detection of 0.01 mg/kg.
1978年至1986年间，对305份苹果样本进行了监测，以检测其生产过程中使用的多种农药残留。其中三份（1%）样本的残留量超过了加拿大《食品和药品法》及相关规定允许的最大残留限量（MRL）；两份样本中分别含有含量为5.9毫克/千克和6.2毫克/千克的伏杀硫磷，一份样本含有含量为6.7毫克/千克的二苯胺，而这两种化合物的最大残留限量均为5.0毫克/千克。经常检测到三氯杀螨醇、硫丹、伏杀硫磷、亚胺硫磷、克菌丹、氨基丁三醇和二苯胺的低残留量；然而，这些残留量远低于最大残留限量。这些残留水平与特定农药处理过的苹果种植面积的调查数据相关。偶尔会检测到西维因、二嗪农、乙硫磷、甲基谷硫磷、对硫磷和二硫代氨基甲酸盐类杀菌剂的残留；所有残留量均远低于最大残留限量，且与使用模式相关。在检测限为0.01毫克/千克的情况下，未发现多氯联苯残留。
