In China, the risk of getting lung cancer from inhaled polycyclic aromatic hydrocarbons (PAHs) is higher in eastern portions of the country, and greater in major cities than in rural areas, researchers have found. Yanxu Zhang et al. modeled the amount of PAH emissions nationwide and characteristics of Chinese populations to determine their risk for lung cancer. Variation in genetic susceptibility was taken into consideration in the risk assessment.
