Scenario outcomes for January 1–February 28, 2010. The red star indicates the Beijing city center. (A) BASE scenario distribution of mean PM2.5 concentrations. (A′) Chemical composition of PM2.5 in the BTH region in the BASE scenario. (B) Mean PM2.5 concentration decrease in the BJR scenario (BJR minus BASE). (B′) Chemical composition of the eliminated PM2.5 over the BTH region in the BJR scenario (BJR minus BASE). (C) Mean PM2.5 concentration decreases in the BTHR scenario (BTHR minus BASE). (C′) Chemical composition of the eliminated PM2.5 over the BTH region in the BTHR scenario (BTHR minus BASE). The region surrounded by the thicker line in A–C is the BTH region. The provinces in eastern China are marked in B. AH, Anhui; HB, Hebei; HN, Henan; IM, Inner Mongolia; JS, Jiangsu; LN, Liaoning; SD, Shandong; SX, Shanxi; TJ, Tianjin.
