Atmospheric Deposition of Benzo[a]pyrene: Developing a Spatial Pattern at a National Scale

Benzo[a]pyrene (BaP), an indicator of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere, is important ambient air pollutant with significant human health and environmental effects. In Czech Republic (CR), BaP, together aerosol ozone, ranks (with respect to limit value exceedances resulting population exposure) among most problematic pollutants. The aim this study develop atmospheric deposition patterns BaP three years, namely 2012, 2015 2019, reflecting different levels. With available measurements, we accounted for dry fluxes, neglecting wet contribution. We assumed, nevertheless, that real dominated by pathways our conditions, which supported measurements from rural site Košetice. spatial pattern was constructed using inferential approach, two input layers, i.e., annual mean concentrations, velocity 0.89 cm·s?1. Though results show overall decrease loads over particular broader Ostrava region, remain very high. presented maps can be considered acceptable approximation total are useful further detailed analysis airborne impacts on environment.
