The regional air quality model CMAQ was used to simulate and evaluate the effect of residential coal combustion emission reduction policies on atmospheric BaP pollution in Beijing-Tianjin-Hebei (BTH) region. The simulations included a base scenario (the year of 2014) and two scenarios of emission reductions. The simulation results:the annual average concentration of atmospheric BaP in BTH in the base scenario was 2.54ng/m3, which was more than twice of the national air quality standard (1ng/m3).The levels of monthly average concentration of atmospheric BaP were in the order:January, April, October, July, reflecting the impact of coal for heating in winter on atmospheric BaP concentration. The atmospheric BaP concentration of southern BTH region was higher than that of the northern region over BTH region, the reason was probably the higher BaP emissions in the south of BTH than in the north. The emissions reduction of rediential coal in January has the most significant effect on reducing concentration of atmospheric BaP and depotion.The concentrations of atmospheric BaP in January over Beijing, Baoding and Langfang in low (scenario1) and high (scenario2) were reduced by 30% and 40% respectively compared with the base scenario.The emissions reduction of rediential coal combustion in April, July and October had little effect on the changes of atmospheric BaP concentration and depotion. Taking control measures of residential coal consumption in all BTH region could more effectively reduce the concentration of atmospheric BaP concentration in this area.
