An Integrated Assessment Model for Fine Particulate Matter in Europe

Water, Air, and Soil Pollution, 2001
Exposure to fine particles in the ambient air is recognized as a significant threat to human health. Two pathways contribute to the particle burden in the atmosphere: Fine particles originate from primary emissions, and secondary organic and inorganic particles are formed from the gas phase from the emissions of 'conventional' pollutants such as SO2 ...

Source Contributions to Ambient Fine Particulate Matter for Canada

Environmental Science & Technology, 2019
Understanding the sectoral contribution of emissions to fine particulate matter (PM2.5) offers information for air quality management, and for investigation of association with health outcomes. This study evaluates the contribution of different emission sectors to PM2.5 in 2013 for Canada using the GEOS-Chem chemical transport model, downscaled with ...

HPC Simulations of the Fine Particulate Matter Climate of Bulgaria

2015
Some extensive numerical simulations of the atmospheric composition fields in Bulgaria have been recently performed. The US EPA Model-3 system was chosen as a modelling tool. The TNO emission inventory was used as emission input. Special pre-processing procedures are created for introducing temporal profiles and speciation of the emissions.

Microfluidic system for fine particulate matter separation and sampling

2016 13th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2016
Air pollution caused by the indoor fine particulate matter cannot be ignored. To monitor the indoor air quality, a portable and uncomplicated separation and sampling device is required. Here, we present the design of fine particles separation and sampling system which is based on air-microfluidic technology.

Fine particulate matter and the risk of autism spectrum disorder

Environmental Research, 2015
The causes of autism spectrum disorder (ASD) are not well known. Recent investigations have suggested that air pollution, including PM2.5, may play a role in the onset of this condition. The objective of the present work was to investigate the association between prenatal and early childhood exposure to fine particulate matter (PM2.5) and risk for ...

Decomposition of Fine Particulate Organic Matter

2020
Fine particulate organic matter (FPOM) ranges in size from 0.45 μm to 1 mm. It serves as an important food source for aquatic fauna, as a substrate for heterotrophic microorganisms, and as a carrier of nutrients, metals and other chemicals. In streams, FPOM is derived from leaf litter, algae and other organisms by physical, chemical, and biological ...

Source contributions to fine particulate matter in an urban atmosphere

Chemosphere, 2005
This paper proposes a practical method for estimating source attribution by using a three-step methodology. The main objective of this study is to explore the use of the three-step methodology for quantifying the source impacts of 24-h PM2.5 particles at an urban site in Seoul, Korea.

Using Sulfur as a Tracer of Outdoor Fine Particulate Matter

Environmental Science & Technology, 2002
Six homes in the metropolitan Boston area were sampled between 6 and 12 consecutive days for indoor and outdoor particle volume and mass concentrations, particle elemental concentrations, and air exchange rates (AERs). Indoor/outdoor (I/O) ratios of nighttime (i.e., particle nonindoor source periods) sulfur, PM2.5 and the specific particle size ...

Sources of fine urban particulate matter in Detroit, MI

Chemosphere, 2007
Data from the speciation trends network (STN) was used to evaluate the amount and temporal patterns of particulate matter originating from local industrial sources and long-range transport at two sites in Detroit, MI: Allen Park, MI, southwest of both Detroit and the areas of heavy industrial activity; Dearborn, MI, located on the south side of Detroit

Seasonal variability of endotoxin in ambient fine particulate matter

Journal of Environmental Monitoring, 2003
Endotoxin is a toxic, pro-inflammatory compound that has been detected in indoor air and dust in homes and occupational settings, and also in outdoor air. Data on the outdoor sampling of endotoxin are limited. Currently, little is known about the seasonal variation and influence of temperature on outdoor endotoxin levels.
