An experimental proficiency test program for ability to screen 104 residual pesticides in agricultural products has been conducted. Eight Japanese laboratories joined the program. Items tested in the present study were limit of detection, internal proficiency test (self spike) and external proficiency test (blind spike). All 104 pesticides were well detected and recovered from agricultural foods in the internal proficiency test. However, the results of the external proficiency test did not completely agree with those of the internal proficiency tests. After 5 rounds of the blind spike test, the ratio of the number of correctly detected pesticides to that of actually contained ones (49 total) ranged from 65% to 100% among laboratories. The numbers of mistakenly detected pesticides by a laboratory were 0 to 15. Thus, there was a great difference among the laboratories in the ability to screen multiresidual pesticides.
开展了一项针对农产品中104种残留农药筛选能力的实验性能力验证测试项目。八个日本实验室参与了该项目。本研究中测试的项目包括检测限、内部能力验证测试（自我加标）和外部能力验证测试（盲样加标）。在内部能力验证测试中，所有104种农药均能从农产品中被良好地检测和回收。然而，外部能力验证测试的结果与内部能力验证测试的结果并不完全一致。经过5轮盲样加标测试后，各实验室中正确检测出的农药数量与实际含有的农药数量（共49种）之比在65%至100%之间。一个实验室误检出的农药数量为0至15种。因此，各实验室在多残留农药筛选能力方面存在很大差异。
