Highly viscous aerosols and cancer risk

A modeling study suggests that highly viscous organic aerosols containing toxic benzo(a)pyrene (BaP), which represents a group of pollutants from organic matter combustion referred to as polycyclic aromatic hydrocarbons (PAHs), can shield BaP from degradation, and that this shielding likely explains observed atmospheric persistence and global transport of BaP; the global lung cancer risk increased by an estimated 4-fold when PAH shielding was incorporated into a global climate model that drives a cancer risk model. - Read at PNAS.org
