Larger systems of benzene ring structure fused together is called PAH
Chemistry of the structures is the same but usually more reactive then benzene
dynamics and trends of these compounds
GENERAL INFORMATION hydrocarbons ( PAHs) in a tropical rain forest
by examining their distribution and relating PAHs concentrations in air to those in external plant parts.
For separation of volatile organic compounds
Octanol-air coef. = [K]octanol/[K]air
Log KOA : octanol-air coefficient
Log KLA : avge. concentration in air
The octanol-air partition coefficient is a measure of chemical partitioning between the atmosphere and the organic matter in the environment.
Log KOWA ( outer wall-air ) vs Log KOA
Regression line only for log KA < 7.5
