Based on weight of evidence for
representative substances, members of this category are considered to be
readily biodegradable. Structural analysis of the streams indicate that
they are not expected to undergo hydrolysis due to the lack of
hydrolysable functional groups.
Due to the low partition coefficients of the
members of this category (log Kow <3), the substances are expected to
have low potential for bioaccumulation or adsorption and therefore no
testing has been conducted on these endpoints. On the basis that members
of this category are expected to have low potential for adsorption to
soil or sediment, the biodegradation in these compartments is not considered
to be relevant.
in air data indicate that the
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.
