"The authors have put an enormous effort into acquiring the data in this book and... it is a very interesting and stimulating read." (Chromatographia, June 2010) “The authors should be commended for providing all of the facts of the controversy in one place. Their call for both sides to get together to study the health issues with reason and respect is also a worthwhile goal because, as they point out; perhaps then ‘this long-standing and somewhat silly dispute could finally he laid to rest.’” (Chemical and Engineering News, September 2009)
