Journal ArticleDOI
Secondary organic aerosol: a comparison between foggy and nonfoggy days.
TL;DR: Enhanced oxidation of SO(2) to sulfate during foggy days was observed, possibly causing the regional aerosol to become more acidic, and lower EC concentrations were observed on foggy Days, suggesting fog scavenging and removal of EC was active as well.
Journal ArticleDOI
Heterogeneity of passenger exposure to air pollutants in public transport microenvironments
Fenhuan Yang,Daya S. Kaul,Kachun Wong,Dane Westerdahl,Li Sun,Kin Fai Ho,Linwei Tian,Peter Brimblecombe,Zhi Ning +8 more
TL;DR: In this article, the authors investigated PM2.5 (particulate matter with aerodynamic diameters smaller than 2.5μm), black carbon (BC), ultrafine particles (UFP) and carbon monoxide (CO) pollutant concentrations in various public road transport systems in highly urbanized city of Hong Kong.
Journal ArticleDOI
Study of MPLNET-Derived Aerosol Climatology over Kanpur, India, and Validation of CALIPSO Level 2 Version 3 Backscatter and Extinction Products
TL;DR: The level 2 aerosol backscatter and extinction profiles from the NASA Micropulse Lidar Network (MPLNET) at Kanpur, India, have been studied from May 2009 to September 2010 as mentioned in this paper.
Journal ArticleDOI
Chemical Characterization of Summertime Dust Events at Kanpur: Insight into the Sources and Level of Mixing with Anthropogenic Emissions
Subhasish Ghosh,Tarun Gupta,Nikhil Rastogi,Abhishek Gaur,A. Misra,Sachchida Nand Tripathi,Debajyoti Paul,Vinod Tare,Om Prakash,Deepika Bhattu,A. K. Dwivedi,Daya S. Kaul,Rosalin Dalai,Sumit Kumar Mishra +13 more
TL;DR: In this paper, the authors quantified chemical properties of dust and the intensity of mixing, due to its interaction with various emissions from anthropogenic activities, during its long range transport, using Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES).
Journal ArticleDOI
Traffic generated non-exhaust particulate emissions from concrete pavement: A mass and particle size study for two-wheelers and small cars
TL;DR: In this article, a fully enclosed laboratory-scale model was fabricated to simulate road tire interaction with a facility to collect particles in different sizes, and it was observed that emission of large particle non exhaust emission (LPNE) as well as PM10 and PM2.5 increased with increasing load.
