Question

What factor significantly influences the volatilization of pesticides?

1. The vapor pressure of the pesticide compounds is a key determinant of volatilization.
2. The color of the pesticide does not affect its volatilization rate.
3. The solubility of the pesticide in water is the primary factor influencing volatilization.
4. The density of the pesticide is the main driver of volatilization.

• A. i only
• B. i, iii
• C. iii, iv
• D. None of these

Answer 1

Answer:

A. i only

• Transfer of pesticides either from plants surface, water or soil to air - Volatilization

• Volatilization depends on the vapour pressure of the pesticide compounds.

• The pesticides maybe carried to long distances as particles as they get adsorbed onto the dust particles.

• Physical transport of pesticides over the ground surface by rainwater - Runoff
