Forensic, Occupational and Environmental Health Sciences are identification sciences dealing with criminal and delicate societal problems for which scanning electron microscopy (SEM) with energy dispersive x-rays (EDAX) and analytical transmission electron microscopy (TEM) are providing increasingly definitive solutions. This is particularly true in the area of particulates. However, electron microscopists working independently in these three related fields are often called upon to identify particulates which have been well characterized by microscopists in one of the other fields of study....
