  • Title: PAHs, PCDD/Fs, PCBs and HCB in leaves from Brisbane, Australia.
    Author: Müller JF, Hawker DW, McLachlan MS, Connell DW.
    Journal: Chemosphere; 2001; 43(4-7):507-15. PubMed ID: 11372834.
    Abstract:
    The concentrations of SOCs in leaves of an evergreen Australian native tree (Melaleuca leucadendra) and grass collected in Brisbane, Australia were determined. The concentrations of PCDD/Fs and PAHs in the leaf tissue were comparable to those reported for urbanised areas in other industrialised countries. A distinct difference in the compound profiles between the leaves of the two species was observed, with higher concentrations of the lower molecular mass PAHs and PCDD/Fs and lower concentrations of the higher molecular mass PAHs and PCDD/Fs in the Melaleuca leaves relative to the grass leaves. The interspecies differences are explained on the basis of the larger size of the lipophilic compartment (for compounds with low K(OA)) and the lower ratio of surface area to volume in the Melaleuca leaves.
