"As we began to prepare the book," Halden explains, "the scope increased from just pharmaceuticals and personal care products to other chemicals, for example flame retardants, compounds used in electronics and in sofas for preventing house fires, and so forth. The book closely examines chemicals that are now on the radar screen for having potential risksthese we call contaminants of emerging concern or CECs."
Following the American Chemical Society symposium, presenters were asked to write a chapter for the forthcoming book. Subsequently, a great deal of additional material was requested from scientific authorities in government and academia worldwide, with each chapter in the 600-page text receiving careful peer review. "We compile a lot of information on chemicals that had previously been discussed and also look at chemicals that have not received much scrutiny," Halden says, adding that the comprehensive treatise will likely remain relevant for many years to come.
The book is organized into three major sections: 1) environmental sources, occurrences and fates of CECs; 2) exotoxicological and human health risks of CECs; and 3) modeling tools, research needs and policy options for managing CECs.
In the years leading up to the ACS symposium, media attention had been gathering around the issue of chemicals of concern, including pharmaceuticals and person
