Seasonal Variation and Sources of Polycyclic Aromatic Hydrocarbons (PAHs) in Indoor and Outdoor Air in a Semi Arid Tract of Northern India
Indoor and outdoor air Gas/Particulate PAHs Seasonality Toxic assessment Source apportionment
2016/3/25
PAHs concentration in particulate and gas phase was investigated in indoor and outdoor air of urban residential and
roadside homes in a semiarid region of India. Samples were collected during winter ...
Kinetic double-layer model of aerosol surface chemistry and gas-particle interactions (K2-SURF): Degradation of polycyclic aromatic hydrocarbons exposed to O3, NO2, H2O, OH and NO3
Kinetic double-layer model aerosol surface chemistry gas-particle interactions K2-SURF
2009/12/31
We present a kinetic double-layer surface model (K2-SURF) that describes the degradation of polycyclic aromatic hydrocarbons (PAHs) on aerosol particles exposed to ozone, nitrogen dioxide, water vapor...
Polycyclic aromatic hydrocarbons（PAHs）in the atmospheres of two French alpine valleys: sources and temporal patterns
Polycyclic aromatic hydrocarbons PAHs French alpine valleys
2009/3/3
Alpine valleys represent some of the most important crossroads for international heavy-duty traffic in Europe, but the full impact of this traffic on air quality is not known due to a lack of data con...
Vehicle fleet emissions of black carbon, polycyclic aromatic hydrocarbons, and other pollutants measured by a mobile laboratory in Mexico City
Vehicle fleet emissions black carbon polycyclic aromatic hydrocarbons Mexico City
2009/2/19
Black carbon (BC) and polycyclic aromatic hydrocarbons (PAHs) are of concern due to their effects on climate and health. The main goal of this research is to provide the first estimate of emissions o...
