INDIRECT PHOTOLYSIS in airOH radical induced indirect photolysis of primary alkyl amines can be estimated with US EPA AOPWIN Program estimating low degradation half-lives (24 hour day and OH radical concentration of 500000 radicales/cm3). Mean value for half-life in air for saturated amines used (OH radical reaction).
atmosphere primary alkyl amines are likely to be degraded by reaction
with hydroxyl radicals. Degradation rates for some components were
calculated with the Atmospheric Oxidation Programme according to
Atkinson (1987). With a concentration of 500,000 OH-radicals/cm3,
degradation half-lives of 7.9 h for 1-tetradecanamine, 7.1 h for
1-octadecanamine, and 3.6 resp. 3.4 h for the cis- and trans-isomer of
oleylamine are calculated. For the exposure calculations, a mean value
for the saturated amines of 7.5 h is used.
Because there are no important releases into the atmosphere and
volatilisation is expected to be negligible, this removal mechanism is
thought to be of low relevance.
