Accurately Quantify PAHs Down to 5 pg On-Column: GC/MS Sim Analysis with the New Rxi®-5Sil MS Column
Polycyclic aromatic hydrocarbons (PAHs) are common environmental pollutants, affecting air, water, and soil quality.
Although naturally occurring, human impact has created a steady increase in environmental levels of PAHs and their
byproducts. PAHs are typically formed through the incomplete combustion of organic materials, such as wood, coal,
and oil, but are also used in manufacturing of some medicines, plastics, and pesticides. Many PAHs are known or
suspected carcinogens. The United States Environmental Protection Agency currently lists and mandates testing of
the 16 PAHs they deem most hazardous.
