Improper uses of pesticides leads to occupational, environmental and food security risks. Ethyl acetate followed by GC determination for the analysis of chlorfenapyr residues in orange and tomatoes were performed. Chlorfenapyr accuracy, repeatability, linearity and specificity were investigated. Pesticide regression coefficients (R(2)) were 0.9953 and 0.9901 in orange and tomatoes, respectively. LODs were 2.3 and 2.4 ?g/kg, respectively, while LOQs were 8.0 and 7.8 ?g/kg, respectively. Recovery% was ranged from 91.12% to 96.54%. The Half-life values (t1/2) were 2.85 and 2.89 days for orange and tomato, respectively. The PHI was 21 and 10 days for orange and tomato, respectively. Detection of Chlorfenapyr PHI residues in this work highlights on the urgent needs for good implementation in Good Agriculture Practices and continuous control for these crops to minimize the health risk to consumption and improve exports.

Abstract
Improper uses of pesticides leads to occupational, environmental and food security risks. Ethyl acetate followed by GC determination for the analysis of chlorfenapyr residues in orange and tomatoes were performed. Chlorfenapyr accuracy, repeatability, linearity and specificity were investigated. Pesticide regression coefficients (R(2)) were 0.9953 and 0.9901 in orange and tomatoes, respectively. LODs were 2.3 and 2.4 ?g/kg, respectively, while LOQs were 8.0 and 7.8 ?g/kg, respectively. Recovery% was ranged from 91.12% to 96.54%. The Half-life values (t1/2) were 2.85 and 2.89 days for orange and tomato, respectively. The PHI was 21 and 10 days for orange and tomato, respectively. Detection of Chlorfenapyr PHI residues in this work highlights on the urgent needs for good implementation in Good Agriculture Practices and continuous control for these crops to minimize the health risk to consumption and improve exports.
