During a 3-year monitoring survey (April 2002-March 2005) of pesticide residues in agricultural products, 592 samples (324 domestic; 268 imported) collected in Hyogo prefecture, Japan were analyzed. The number of pesticides tested increased from 232 in FY 2002 to 323 in FY 2004. The purpose of the study was to clarify the residue status by accumulating information about pesticides detected frequently, to allow effective and efficient regulation under the new "Positive List" legislation to be implemented in FY 2006. Overall, 47% of domestic and 61% of imported samples contained detectable residues and ca. 60% of positive samples contained multiple residues. The limit of quantitation was set at 0.01 microg/g and the limit of detection was 0.001-0.003 microg/ g. Most of the residues were present at low concentrations: 80% of the detections in samples excluding imported citrus fruits were < 0.05 microg/g. More than 5 different pesticides (> 0.01 microg/g) were detected simultaneously in 13 samples. The sum of the ratios of residues to MRLs was calculated as one of the indexes to represent the risk of multiple residues, and they exceeded 100% in 3 imported frozen vegetables; baby kidney bean, spinach, Welsh onion. Samples in violation of the Food Sanitation Law were not found in our survey, but 1.9% of the samples might be in conflict with the new "Positive List" legislation.
在一项针对农产品农药残留的为期3年的监测调查（2002年4月 - 2005年3月）中，对在日本兵库县采集的592个样本（324个国产；268个进口）进行了分析。所检测的农药数量从2002财年的232种增加到2004财年的323种。该研究的目的是通过积累有关频繁检测到的农药的信息来阐明残留状况，以便在2006财年实施新的“肯定列表”法规时进行有效且高效的监管。总体而言，47%的国产样本和61%的进口样本含有可检测到的残留，约60%的阳性样本含有多种残留。定量限设定为0.01微克/克，检测限为0.001 - 0.003微克/克。大多数残留以低浓度存在：在不包括进口柑橘类水果的样本中，80%的检测值<0.05微克/克。在13个样本中同时检测到5种以上不同的农药（>0.01微克/克）。计算残留量与最大残留限量（MRL）的比率之和作为表示多种残留风险的指标之一，在3种进口冷冻蔬菜；嫩菜豆（四季豆）、菠菜、大葱中该指标超过了100%。在我们的调查中未发现违反《食品卫生法》的样本，但1.9%的样本可能与新的“肯定列表”法规存在冲突。
