One paragraph, so you can see how it reads
EMT308 · UNIT 1 MOVEMENT AND ABSORPTION OF PESTICIDES IN SOIL
The conversion of a solid or liquid into a gas is called volatilization. A pesticide, once volatilized, can move in air currents away from the treated surface. An important factor that determines whether a pesticide will volatilize is vapour pressure. The higher the vapour pressure, the more volatile the pesticide.
