Several mechanisms for degradation of chemicals bound to particles in air or in
gas phase are known. Following the physical and chemical properties and the
structure of Piperonyl butoxide it is assumed that degradation and persistence of
the active substance mainly depends on reaction with hydroxyl radicals. The
photochemical degradation of Piperonyl butoxide in air was estimated using the
model AOPWIN (version 1.80). The constants for reaction on different adsorption
systems and mechanisms of binding to hydroxyl radicals were estimated to be
51.273x 10-12 cm³/molec. sec for hydrogen abstraction and 56.3119 x 10-12 cm³/molec.
sec for addition to aromatic rings.Half-life in the troposphere was calculated to
be 3.579 hours for overall OH rate constant.
Rate constant (for indirect photolysis): = 0.0000000001075849 cm³/(molecule*sec)
Degradation in % (for indirect photolysis): = 50 after 3.6 hour(s)
Applicant's summary and conclusion
- Conclusions:
- Rate constant (for indirect photolysis): = 0.0000000001075849 cm³/(molecule*sec) Degradation in % (for indirect photolysis): = 50 after 3.6 hour(s)
