AIA_NOV2015_ Arson and petroleum forensics

525 views

Published on

Introduction to talk to be presented on Nov 17, 2015. The introduction shows the multiple compounds that are present in crude oil and refined products which can be used to determine sources of releases and identify products used in arson cases. Such compounds include polycyclic aromatic hydrocarbons, alkylated benzenes, and petroleum biomarkers.
