It is hoped that the information in Herbal Products Toxicology and Clinical Pharmacology, Second Edition will be used to solve clinical or forensic problems involving dietary supplements, promote dialogue between health care professionals and patients, and stimulate intellectual curiosity about these products, fostering further research into their therapeutic and adverse effects. 

How do we understand the special difficulties of obtaining analysis data relating to forensic problems. 

When matter is excited to high energy levels, by flame, electric arc or spark, it generally decomposes into atomic ions. The dissociation of electrons is reversed as the ion leaves the high-energy zone and results in emission which is characteristic of each ion present. Transitions include those in which electrons drop from outer to inner orbits as well. These phenomena are responsible for the application of emission spectrometry to elemental analysis over wide concentration ranges in the steel, aluminum, and other industries as well as a popular technique fw environmental and forensic problems. 

Co, and the density) were needed to identify 16 of 19 papers correctly. The classification of paper samples by pattern recognition methods may be useful in forensic problems.
