Abstract:
... Understanding the emission sources of volatile organic compounds (VOCs) is critical for air pollution mitigation. Continuous measurements of atmospheric VOCs were conducted from January to February in Hangzhou in 2021. The average measured concentration of total VOCs (TVOCs) was 38.2 ± 20.9 ppb, > 42% lower than that reported by previous studies at the urban center in Hangzhou. The VOC concentrati ...

However, there is a lack of information on its effectiveness. We used the Testing Re-entrained Aerosol Kinetic Emissions from Roads (TRAKER) method to monitor different types of roads in Baoding city before and within 1 hr after water-sprinkl ...

Abstract:
... The presence of nonzero conjectural variations in pollution abatement and output make emission taxes less effective with respect to reducing emissions. This has implications for the characterization of the optimal emission tax, particularly in an international context where there are large asymmetries in pollution intensities. A higher degree of collusion in output between polluting firms results ...

Abstract:
... Reliable prediction for the concentration of PM₂.₅ has become a hot topic in pollution prevention. However, the prediction for PM₂.₅ concentration remains a challenge, one of the reasons is that current prediction methods do not consider the relevance of PM₂.₅ concentration among surrounding areas. In this paper, we propose the assumption that the PM₂.₅ concentration has spatial interaction, which ...
