The predominance of angiosperm and generic plant constituents in clams from Kildala Arm is consistent with typical diagenetic processes in natural sedimentary environments where the fragile leaves of deciduous trees and other
Doxorubicin are rapidly degraded, leading to incorporation of plant waxes, sterols and terpenoids into sediments and the diagenic production of sterenes and aromatised triterpenoids (Gagosian and Farrington, 1978, Otto and Simoneit, 2001, Otto et al., 2005, Wakeham et al., 1980b and Yunker and Macdonald, 2003). In contrast, the diterpenoids are largely contained in the resinous
tissues of conifers, producing substantially less exposure to reworking by physical processes and bacteria in sediments, and a substantially longer preservation in woody tissues (Otto and Simoneit, 2001 and Otto et al., 2005). Accordingly, the dramatic differences in diterpene bioavailability for beaches in Kitimat Arm can be attributed to exposure to Eurocan effluent where the conifer diterpenes have been released from the resinous tissues during pulp production and are much more bioavailable than is usual for conifer plant detritus (average BSAFs up to 125; Fig. 6a–f).
