Hi El C - It was far too weighted to that work - would require also referencing the many works since Oberdorster refuting it, and also put it in context with previous. Therefore, reference to the overview Book chapter is okay, and also the most recent Toxicology paper would be typical. In other words, to single out one or two works from 2004 - 2005 would requre much more justification.
