On the Morphology and Composition of Particulate Matter in an Urban Environment.

Aerosol Air Qual Res 2018 Sep;18(6):1431-1447

Institute of Space Technology (IST), Islamabad, Pakistan.

Particulate matter (PM) plays a vital role in altering air quality, human health, and climate change. There are sparse data relevant to PM characteristics in urban environments of the Middle East, including Peshawar city in Pakistan. This work reports on the morphology and composition of PM in two size fractions (PM and PM) during November 2016 in Peshawar. Read More

Spatial Variation of Ground Level Ozone Concentrations and its Health Impacts in an Urban Area in India.

Aerosol Air Qual Res 2017 ;17(4):951-964

Department of Mining Engineering, National Institute of Technology, Rourkela, Odisha-769008, India.

The present study was designed to analyze the spatial distributions of ground-level ozone (GLO) concentrations in Ranchi (Jharkhand, India) using geostatistical approaches. From September 2014 to August 2015, monthly GLO concentrations were monitored in 40-identified locations distributed in the region of study. In every month, the monitoring was done at three different time periods of the day; 5. Read More

Comparison of PM Exposure in Hazy and Non-Hazy Days in Nanjing, China.

Aerosol Air Qual Res 2017 Sep;17(9):2235-2246

Lamont-Doherty Earth Observatory of Columbia University, Palisades, NY 10964, USA.

Fine particulate matter (PM), levels of which are about 6 times the 2014 WHO air quality guidelines for 190 cities in China, has been found to be associated with various adverse health outcomes. In this study, personal PM exposures were monitored along a fixed routine that included 19 types of non-residential micro-environments (MEs) on 4 hazy days (ambient PM 292 ± 70 μg m) and 2 non-hazy days (55 ± 16 μg m) in Nanjing, China using miniaturized real-time portable particulate sensors that also collect integrated filters of PM (MicroPEMs, Research Triangle Institute (RTI), NC). Gravimetric correction is necessary for nephelometer devices in calculating real-time PM levels. Read More

Evaluation of PM surface concentration simulated by Version 1 of the NASA's MERRA Aerosol Reanalysis over Israel and Taiwan.

Aerosol Air Qual Res 2017 Jan 1;17(1):253-261. Epub 2017 Jan 1.

Department of Atmospheric Sciences, National Central University, Taoyuan, Taiwan.

Version 1 of the NASA MERRA Aerosol Reanalysis (MERRAero) assimilates bias-corrected aerosol optical depth (AOD) data from MODIS-Terra and MODIS-Aqua, and simulates particulate matter (PM) concentration data to reproduce a consistent database of AOD and PM concentration around the world from 2002 to the end of 2015. The purpose of this paper is to evaluate MERRAero's simulation of fine PM concentration against surface measurements in two regions of the world with relatively high levels of PM concentration but with profoundly different PM composition, those of Israel and Taiwan. Being surrounded by major deserts, Israel's PM load is characterized by a significant contribution of mineral dust, and secondary contributions of sea salt particles, given its proximity to the Mediterranean Sea, and sulfate particles originating from Israel's own urban activities and transported from Europe.

Measurement of Soluble and Total Hexavalent Chromium in the Ambient Airborne Particles in New Jersey.

Aerosol Air Qual Res 2014 Dec;14(7):1939-1949

Rutgers Environmental and Occupational Health Science Institute, Piscataway, New Jersey 08854, USA.

Hexavalent chromium (Cr(VI)) in ambient airborne particulate matter (PM) is a known pulmonary carcinogen and may have both soluble and insoluble forms. The sum of the two forms is defined as total Cr(VI). Currently, there were no methods suitable for large-scale monitoring of total Cr(VI) in ambient PM. Read More

Validation of MicroAeth® as a Black Carbon Monitor for Fixed-Site Measurement and Optimization for Personal Exposure Characterization.

Aerosol Air Qual Res 2014 Feb;14(1):1-9

Lamont-Doherty Earth Observatory of Columbia University, New York, NY, USA.

This paper reports on validation experiments with the recently developed microAeth®, a pocket-sized device which is able to obtain real-time and personal measurements of black carbon (BC) aerosol. High reproducibility was observed when comparing the results from six new individual units during fixed-site monitoring out of a window (relative standard deviation [RSD] = 8% ± 5%, N = 1442). The results obtained from the microAeth devices agreed with those obtained from a full size rack mounted Aethalometer, based on both the 1-minute data (R = 0. Read More

Correction factor for continuous monitoring of wood smoke fine particulate matter.

Aerosol Air Qual Res 2011 Jun;11(3):315-322

Center for Environmental Health Sciences, Department of Biomedical and Pharmaceutical Sciences, The University of Montana, 32 Campus Drive, Missoula, Montana, 59812, U.S.A.

The US Environmental Protection Agency (EPA) has designated a handful of instruments as Federal Reference or Federal Equivalency Methods (FRM and FEM, respectively) for the monitoring of fine particulate matter (PM). More commonly used for indoor exposure assessment studies are optical scanning devices such as the DustTrak (TSI) due to the their portability and affordability. It is recommended by the manufacturer of these instruments that a "correction factor" be applied when assessing source-specific conditions. Read More
