[Rockhounds] Natural asbestos minerals found in Las Vegas region's dust

[DON HALTERMAN]

Brenda Buck and Rodney Metcalf are alarmists who have been told that they are wrong, yet they still persist.  I gave an interview discrediting their findings and only one sentence from my interview appeared in the article (that was several years ago).  I have also given a number of presentations refuting their work.  FYI, a mineral is either asbestos or it isn't.  Saying something is "asbestos-like" doesn't accomplish anything because it doesn't speak to the possible health effects of a non-asbestos mineral.  Palygorskite is a clay mineral but Brenda Buck continuously uses the term asbestos to refer to it.  

My associates who have analyzed the material have found some genuine asbestos minerals, but not as much as Buck and Metcalf claim.  Neither Buck nor Metcalf are trained or certified asbestos analysts, or at least they weren't the last time I checked. 

File this one under the heading of "don't believe everything you read."  There is some truth in it, but also a lot of distortion.
