Measured data are not available for photodegradation for any of the
HABs. A photodegradation study for the base material, LAB, resulted in
less than 1% degradation in 14 days, although sensitized photolysis
could not be ruled out as a possible transformation process.
Photodegradation was estimated with EPI Suite (USEPA 2000) using the
same four representative constituents used to estimate log Kow and water
solubility, p-bis (1-methylundecyl) benzene, 2,11-diphenyldodecane,
1,4-dihydro-1,4-dipropyl-6-(1-methylundecyl)-naphthalene, plus a
representative trialkylbenzene with similar molecular weight
(1-methyl-5-(1-methylundecyl)-2-(1-pentyl) benzene). These materials
were also used in the fugacity modelling. Results indicate that in the
presence of OH radicals at 25 °C, half-lives of these representative
constituents would range from approximately 1.3 to 10 hours (based on
1.5 x 106 OH radicals/cm3). The rate constants ranged from 25.95 x 10-12
to 96.42 x 10-12 cm3/molecules-sec for the five materials. However,
relative to the aerobic biodegradation, photolysis would be too slow to
significantly alter the environmental levels of LAB. Therefore, based
on the similarity of chemical structure, and the low volatility of these
compounds, photodegradation would not be expected to be a significant
mechanism for degradation of the HABs.
