Determination of Bifenthrin Residues on the Eggplant’s Soil, Leaf and Fruits

The determination of Bifenthrin residues considered one of the most significant aspect, especially in the environmental pollution. The estimation of Bifenthrin residues in leaves, soil, and the eggplant fruits revealed that the residues can be decreased faster in the soil and the fruits compared to the leaves. The dissipation period in terms of soil and fruits was 7 days, while in the case of the leaves was 10 days for the both concentrations 1 and 1.5 mL L-1. As the results also confirmed that the dissipation of Bifenthrin residues are subjected to the first-order kinetic reaction. All residues demonstrated that the rates of dissipation almost resemble for both used concentrations. In the soil, leaves, and fruits for 1 and 1.5 mL L-1 were 0.303, 0.403, 0.374, 0.380, 0.469, and 0.463 day-1 respectively. As this kinetic reaction conducted to the half-life of Bifenthrin residues on leaves, soil, and fruits for both concentrations as following: 1.8, 1.8, 2.2, 1.7, 1.4, and 1.4 days respectively. The study also showed the lack of importance of food processes in reducing Bifenthrin residues, suggesting that the consumption of the eggplant depends on the safety removing Bifenthrin residues compared to conducting food operations.
