Influence of fireworks emission on aerosol aging process at lower troposphere and associated health risks in an urban region of eastern central India.

Atmos Pollut Res 2020 Apr 21. Epub 2020 Apr 21.

School of Studies in Chemistry, Pt. Ravishankar Shukla University, Raipur, 492010, Chhattisgarh, India.

To study the influence of fireworks in atmospheric aerosols and their effect on health during the extreme firework days, fireworks tracer metals and carbonaceous species in size-distributed aerosols in the lower troposphere at Raipur in eastern central India were investigated during the 2018 Deepawali festival. Aerosol samples were collected, before Deepawali period (BDP, n = 5), during Deepawali period (DDP, n = 5) and after Deepawali period (ADP, n = 5). Bimodal size-distribution with intense fine mode peak was found for Na during DDP. Read More

Representativeness of an air quality monitoring station for PM and source apportionment over a small urban domain.

Atmos Pollut Res 2020 Feb;11(2):225-233

European Commission-Joint Research Centre, Directorate for Energy, Transport and Climate, 21027, Ispra, Italy.

In this study, PM concentrations together with the water-soluble ionic compounds and total elements were simultaneously measured at 16 sites in the city of Varese located in Northern Italy within a domain of 2 × 2 km. The center point of this domain consisted of an existing urban air quality monitoring station. The representativeness of the monitoring station for PM mass and chemical composition was estimated using a methodology relying on statistical/geostatistical analyses. Read More

Intra-urban variability of the intake fraction from multiple emission sources.

Atmos Pollut Res 2018 Nov;9(6):1184-1193

Systems Research Institute, Polish Academy of Sciences, Warsaw, Poland.

Background: Ambient air pollution and associated adverse health effects are among most acute environmental problems in many cities worldwide. The intake fraction () approach can be applied for evaluating the health benefits of reducing emissions, especially when rapid decisions are needed. Intake fraction is a metric that represents emission-to-intake relationship and characterizes abatement of exposure potential attributed to specific emission sources. Read More

Evaluation of PM surface concentrations simulated by Version 1 of NASA's MERRA Aerosol Reanalysis over Europe.

Atmos Pollut Res 2017 Mar 3;8(2):374-382. Epub 2016 Nov 3.

Département de géographie, Université Laval, Quebec City, Quebec, Canada.

This article evaluates the concentrations of particulate matter (PM) and some of its chemical speciation such as sulfate, organic carbon, black carbon and sea salt particles simulated at the surface by Version 1 of the Aerosol Reanalysis of NASA's Modern-Era Retrospective Analysis for Research and Application (MERRAero) over Europe. Measurement data from the European Monitoring and Evaluation Programme database were used. The concentrations of coarse PM (PM), fine PM (PM), sulfate and black carbon particles are overall well simulated, despite a slight and consistent overestimation of PM concentration, and a slight and consistent underestimation of PM and sulfate concentrations throughout most of the year.

Source Identification of Coarse Particles in the Desert Southwest, USA using Positive Matrix Factorization.

Atmos Pollut Res 2017 Sep;8(5):873-884

U.S. EPA, Office of Research and Development, 944 E. Harmon Ave, Rm. 235, Las Vegas, NV 89119,

The Desert Southwest Coarse Particulate Matter Study was undertaken to further our understanding of the spatial and temporal variability and sources of fine and coarse particulate matter (PM) in rural, arid, desert environments. Sampling was conducted between February 2009 and February 2010 in Pinal County, AZ near the town of Casa Grande where PM concentrations routinely exceed the U.S. Read More

A Reduced Form Model for Ozone Based on Two Decades of CMAQ Simulations for the Continental United States.

Atmos Pollut Res 2017 Mar;8(2):275-284

AMAD/NERL, U.S.E.P.A., Research Triangle Park, NC, USA.

A Reduced Form Model (RFM) is a mathematical relationship between the inputs and outputs of an air quality model, permitting estimation of additional modeling without costly new regional-scale simulations. A 21-year Community Multiscale Air Quality (CMAQ) simulation for the continental United States provided the basis for the RFM developed in this study. Predictors included the principal component scores (PCS) of emissions and meteorological variables, while the predictand was the monthly mean of daily maximum 8-hour CMAQ ozone for the ozone season at each model grid.

Development and laboratory evaluation of a compact swirling aerosol sampler (SAS) for collection of atmospheric bioaerosols.

Atmos Pollut Res 2015 Jul 5;6(4):556-561. Epub 2016 Jan 5.

School of Energy and Environment, City University of Hong Kong.

Inhalation of infectious bioaerosols has been linked to a variety of respiratory diseases. However, efficient sampling techniques to allow high temporal resolution sampling are limited to collect and study bioaerosols in the various occupational and ambient micro-environmental atmospheres. This study introduces a medium flow swirling bioaerosol sampler (SAS) approach that collects atmospheric bioaerosols at the flow rate of 167 Lpm (10 cubic meter per hour). Read More

Effect based monitoring of seasonal ambient air exposures in Australia sampled by PUF passive air samplers.

Atmos Pollut Res 2010 Jan;1(1):50-58

The University of Queensland, Entox (The National Research Centre for Environmental Toxicology), Brisbane QLD 4108, Australia.

There has been relatively little bioanalytical effect based monitoring conducted using samples derived from polyurethane foam (PUF) passive air samplers. Combining these techniques may provide a more convenient and cost effective means of monitoring the potential for biological effects resulting from exposure to complex mixtures in a range of scenarios. Seasonal polycyclic aromatic hydrocarbon (PAH) levels were monitored at sites around Australia using direct chemical analysis. Read More
