In recent years, pesticides were used heavily in Palestine, which led to the contamination of soil and water and causing many diseases. Many studies focused on the impact of pollutants such as pesticides and oil on soil, humans, animals, plants and the environment in general.
Using column study the amount of glyphosate in soil decreases with increasing depth of soil, where it is for 0-30cm(11ppm) > 30-60cm(6ppm) > 60-100cm(2ppm) due to organic content and metal oxides founded in soil that can form stable complexes with glyphosate.
When we increased the concentration of glyphosate, the amount of glyphosate (contaminant) in leachate where found to be 25x (15.96ppm) >15x (3.91) > 5x (3ppm) column.
The behavior of glyphosate leachate fits the first order reaction and the isotherm is in according with the Freundlich adsorption equation with R2 value 0.98, k value 6.4 and n value 1.07 which indicates good adsorption to soil.
