ABSTRACT

This study investigates the levels of pesticide residues in Cucumbers (Cucumis sativus), potatoes (Solanum tuberosum subsp. Tuberosum) and tomatoes (Lycopersicon esculentum). The samples were minced in a food processor initially subjected to extraction followed by cleanup using solid phase extraction (SPE) column. Separation was performed on a GC capillary column (Rtx-5 ms-30 m × 0.25 mm× 0.25 μm). The sample was injected by using splitless mode, helium as the carrier gas followed by quadrupole mass spectrometry detection. The mobile phase flow rates, column temperatures, and MS parameters were all optimized to reach high sensitivity and selectivity. Seven pesticides were detected in tomatoes sample, six in cucumber and four in potatoes samples. The findings indicate risks and concerns for public health.
