BACKGROUND: The objective of this study was to determine the residual concentrations of @entity21097 and @entity5051 in @entity9688 grown in greenhouse. The effect of some simple processing procedures on both @entity21097 and @entity5051 residues were also studied. METHODS: Ten active greenhouses that produce @entity9688 were randomly selected. @entity21097 and @entity5051 as the most widely used pesticides were measured in @entity9688 samples of studied greenhouses. Moreover, the effect of storing, washing, and peeling as simple processing procedures on both @entity21097 and @entity5051 residues were investigated. RESULTS: One hour after pesticide application; the maximum residue levels (MRLs) of @entity21097 and @entity5051 were higher than that of Codex standard level. One day after pesticide application, the levels of pesticides were decreased about 35 and 31% for @entity21097 and @entity5051 , respectively, which still were higher than the MRL. Washing procedure led to about 51 and 42.5% loss in @entity21097 and @entity5051 residues, respectively. Peeling procedure also led to highest loss of 93.4 and 63.7% in @entity21097 and @entity5051 residues, respectively. The recovery for both target analytes was in the range between 88 and 102%. CONCLUSION: The residue values in collected samples one hour after pesticides application were higher than standard value. The storing, washing, and peeling procedures lead to the decrease of pesticide residues in greenhouse @entity9688 . Among them, the peeling procedure has the greatest impact on residual reduction. Therefore, these procedures can be used as simple and effective processing techniques for reducing and removing pesticides from greenhouse products before their consumption.
