[PW] PCB migration map

A Toxic Journey

High above the Arctic Circle, polar bears inhabit some of the most 
remote and seemingly pristine territory on earth. Yet, scientists have 
discovered that these bears are highly contaminated with industrial 
chemicals, including toxic, long-lived PCBs. There is no way to discover 
exactly how the PCBs made their way to the Arctic. But drawing from 
historical accounts and scientific studies it is possible to imagine the 
path of an individual PCB molecule. Though the specific route and events 
in this journey are hypothetical, the plot is scientifically plausible...

Based on the chapter "To the Ends of the Earth," from Our Stolen Future 
by Theo Colborn, Dianne Dumanoski and John Peterson Myers
