The impact of pesticides use on newly reclaimed soils
Abstract
Pesticides that have become essential elements of modern agriculture, are considered major sources of diffuse pollutants that cause health implications upon living organisms. The objective of this research was to study the impact of Imidacloprid on the physical and chemical characteristics of newly reclaimed soil in Toshka area. Water and soil (successive depths 0-25, 25-50 cm) samples were collected from Nasser Lake and Toshka area. Before any addition, complete analyses of soil and water were carried out. The experiment was carried out using PVC columns filled with the soil samples. Three cylinders were used for the different concentrations of Imidacloprid prepared in the lab 1/2X, X, and 2X. Three volumes were added weekly and drained water was subjected to complete analysis. The results showed that Imidacloprid percentage in leachate increased gradually after the 5th addition.
[...]
The rate of Imidacloprid adsorption decreased while degradation percent increased with soil depth.
