The disposition of 14C-labelled hexachlorobenzene (HCB) and 2,4',5-trichlorobiphenyl (triCB) was studied in cod (Gadus morhua) and rainbow trout (Oncorhynchus mykiss). For both compounds tape section autoradiography revealed substantial amounts of radiolabelled material in the central nervous system (CNS) of cod

Folia microbiologica, 43(1), 79-84 (1998-05-07)
Degradation of lower-chlorinated and higher-chlorinated PCB congeners (Delor 103 and Delor 105 as equivalents of Aroclor 1242 and Aroclor 1254, respectively) by the white-rot fungus Phanerochoete chrysosporium was investigated in N-limited and non-limited media. No degradation of either Delor 103
