A study examined the partitioning of polycyclic aromatic hydrocarbons between vegetation and the atmosphere throughout the growing season and under natural conditions. Evidence indicates that atmospheric semivolatile organic compounds undergo an annual partitioning cycle with the surface of the eart...
