Methods of analysis for polynuclear aromatic hydrocarbons in environmental samples

摘要: For many years industry, academia, and the federal government have been involved in development of methods for analysis polynuclear aromatic hydrocarbons (PNA's) environment. This concern measurement PNA's has arisen because some these materials are known carcinogens. The presence compounds environment is well established. In particular, found sediments marine organisms. They can enter ocean by routes, including petroleum spills, runoff from roads, sewage, effluents industrial processes, fallout atmosphere. order to obtain baseline data on this subject, several ago API initiated a project which continuing effort was made measure petroleum, fish, foodstuffs. question origin, distribution, fate keen interest years. Data obtained program tend support earlier conclusions drawn Blumer Youngblood Hites that present most likely derived high temperature combustion sources. conclusion based distribution alkyl substituted measured relative parent PNA's.
