Results and discussion
Any other information on results incl. tables
A calculated overall OH reaction rate of 38.1498×10-12 cm3/molecule-sec is obtained by addition reactions to aromatic rings. Based on this OH rate constant and using a 24-hrs day with 0.5×106 OH radicals/cm3, a half life of triflumuron in air of 0.421 days, corresponding to a chemical lifetime of 0.61 days was assessed. Employing a conservative approach, using only half of the estimated overall OH reaction rate (19 ×10-12 cm3/molecules-sec), a maximum chemical lifetime of triflumuron in air of 1.2 days is to be expected.
On the account of the chemical lifetime of triflumuron in the air (at the most 1.2 days) it is to be expected that the active substance can not be transported in the gaseous phase over large distances and can not accumulate in the air. Thus, no difference in the behaviour between triflumuron and other organic substances emitted into the air from natural sources (e.g. plants, soil) is indicated.
Applicant's summary and conclusion
- Conclusions:
- Atkinson calculation of a DT50 of 0.421 days from the EFSA Conclusion corresponds to lifetime of 0.61 days.
The chemical stability of Triflumuron in air is not determined by an attack at one single site, but at different parts of the molecule. This should result in the formation of various primary radicals leading to secondary oxidation products, which can be eliminated from the air by wet and/or dry deposition.
On account of the chemical lifetime of Triflumuron in the air of at the most 1.2 days it is to be expected that the active ingredient can not be transported in gaseous phase over large distances and can not accumulate in the air. Thus, no difference in the behaviour between Triflumuron and other organic substances emitted into the air from natural sources (e.g. from plants, soil) is indicated. - Executive summary:
Based on the calculation according to Atkinson the chemical lifetime of the parent compound Triflumuron in the air is assessed by AOPWIN (version 1.90). A value (τ) of at the most 1.2 days results, with respect to the OH radical reaction, only.
