Dioxin and Willamette River Pollution: A First Step Into the Toxic Waters

This post provides some preliminary research and analysis on dioxin pollution in the Willamette Watershed connected to pulp and paper mill effluents.

I was recently at an environmental history conference and found myself in a discussion with someone doing research on dioxin pollution from pulp and paper mill effluents. As we were sharing stories, I realized that I had not seen a single reference to the word “dioxin” in any of the government reports, newspaper articles, professional journals, letters, or other primary sources from the 1900s into the 1960s that I have consulted thus far. Over the past few weeks, I’ve searched various primary and secondary sources, with the goal of determining just when dioxins became a known toxin, and when they were linked empirically with pulp and paper mill effluents, to determine if I had inadvertently missed something very important (and would have to re-write my thesis), or if this type of pollution hadn’t been discovered until after the 1960s (and I was OK).

Here is what I have found thus far . . . Read the rest of this entry »
