The principal loss processes will depend on local conditions but half-lives can be expected to range <br /> rom a couple of days to a few months. When adsorbed to sediment, biodegradation occurs much more rapidly than in <br /> the overlying water column. When spilled on land, naphthalene is adsorbed moderately to soil and undergoes <br /> iodegradation.
