293. JX 4.3 Gonggu Flyover: air quality. Table VI-24 presents the predicted maximum pollutant concentrations near the Gonggu Flyover boundary, with modeling results shown in Figure VI-13. The results indicate that the maximum CO and NO2 ground-level concentration values will comply with Class II standard limits of Ambient Air Quality Standard (GB 3095-2012) during future operation.
