Simulation and quantification of the natural decay of a typical endocrine disrupting chemical Atrazine in an aquatic system

- Degradation of Atrazine (ATZ) in an outdoor environment was investigated.
- The overall decay rate constant of ATZ in outdoor is slower in neutral pH and faster at extreme pH levels.
- Hydrolysis was found to be a slow but continuous process.
- A model incorporating ATZ decay rate constants, pH levels and temperature was proposed.
- Photolysis is a non-continuous but fast and dominant process.
