Diagnostic Ratio Plot of PAH Compounds

5 Outlooks for Environmental Forensics – Part Three: Fundamentals behind Graphs and Diagnostic Ratios

There have been many publications on the use of environmental forensics on a variety of different contaminants. One of the most common good of compounds analyzed in EFIs are the polycyclic aromatic hydrocarbons (PAHs). These compounds have many ‘diagnostic ratios’ that are used to determine the different sources that generated the PAHs.

5 Outlooks for Environmental Forensics – Part Two: Regulatory Compounds

Environmental forensics investigations are many times instigated after the fact. Data may have been collected for years prior to the client suggesting or determining that an environmental forensics investigation is needed. In these cases, the environmental forensics scientist must work with the data they have. In a more idealized situation, it would be much better if those collecting the data realized that the data might some day be used in litigation to determine source.
