1 Average chlorine content, chlorine atoms per 

 molecule, and molecular weight of selected 

 Aroclor and Kanechlor PCB formulations (after 



Roberts et al . 1978) 6 



2 PCB concentrations in field collections of 

 selected species of flora and fauna. Values 

 shown are in mg/kg (ppm) fresh weight (FW), 



dry weight (DW), or lipid weight (LW) 11 



3 Acute toxicities of Aroclor PCBs to selected 



aquatic species 37 



4 Toxicities of Aroclor PCBs to selected species 

 of birds and mammals administered via dietary, 



oral, dermal, or intraperitoneal routes 40 



5 Aroclor 1254 bioconcentration factors (BCF) 



for selected species of whole aquatic organisms 45 



6 Maximum acceptable toxicant concentration (MATC) 

 values for Aroclor PCBs and selected species of 

 aquatic organisms, based on exposure for life 

 cycle, partial life cycle, or early life stage 



(from EPA 1980) 51

various resources and human health 58
