The phototransformation in air half-lives of the substances in the category range from 1907 to 6.3 days.
from Atkinson (1985) were available for the substances methane, ethane,
propane, butane and isobutane. Measured data from author and other
investigators were quality assessed and then used to develop rate
constants for different chemicals. Therefore, this value represents a
valid rate constant for the substances based on all valid studies at the
time of publication.
phototransformation half-life of methane is 1907 days, ethane is 59
days, propane is 14 days, butane is 6.3 days and isobutane is 6.8 days.
