Benzo[e]pyrene in leaves of poplars from the Saartal

Decreasing contamination since the early 1990s

Benzo[e]pyrene is a product of combustion of fossil fuels and other organic material. It is environmentally persistent and accumulates in organisms.
Concentrations of benzo[e]pyrene in and on leaves of lombardy poplars from the Saartal have declined significantly since the early 1990s. This indicates that atmospheric benzo[e]pyrene pollution has decreased due to improved emission protection.
