Recent epidemiological evidence strongly suggests that ambient-particle-associated acidity is more closely correlated with total mortality and hospital admissions for respiratory disease than indices of total particulate mass. In addition, evidence is accumulating to support the hypothesis that the number of ultrafine (d < or = 200 nm) acid particles, rather than ambient mass, is an important determining factor affecting lung injury. Both outdoor and indoor air environments are dominated by…

Measuring Ambient Acidic Ultrafine Particles Using Iron Nanofilm Detectors: Method Development

The number concentration and size-resolved properties of acidic ultrafine particles have been observed to more closely associate with adverse health effects than do indices of total particulate mass.

Field evaluation of nanofilm detectors for measuring acidic particles in indoor and outdoor air.

The work established that the detectors could be used with confidence in temperate climates and under extreme high humidity and high temperature, the surface film was liable to detach from the support, but remaining portions of the film still produced reliable data.

Diffusion Sampler for Measurement of Acidic Ultrafine Particles in the Atmosphere

The adverse health effect of acidic ultrafine particles (AUFPs) has been widely recognized in scientific societies. These particles mainly deposit on the surface by diffusion and so far there is no

Using technologies developed within complementary disciplines, together with the development of aerosol–specific methods, a basis for characterizing single sub–100 nm (ultrafine) particles and features in terms of size, morphology, topology, composition, structure and physicochemical properties is established.

Review of Measurement Methods and Compositions for Ultrafine Particles

Impactor, virtual impactor/aerosol concentrator, and aerodynamic lenses are used to separate the ultrafine particle (UP) fraction from other particle sizes for chemical analysis. Cascade impactors,

Airborne Fine and Ultrafine Particles Near the World Trade Center Disaster Site

Documentation of the airborne fine and ultrafine particles produced by the terrorist attack on the World Trade Center (WTC), particularly while fires were burning, was essential for evaluating the

Assessing exposure to airborne nanomaterials: Current abilities and future requirements

For over half a century, health-related aerosol exposure measurements have been characterized in terms of the mass of material present per unit volume of air. Yet recent research has challenged the

Ultrafine particles at workplaces of a primary aluminium smelter.

The study shows the existence of elevated number concentrations of ultrafine particles in both potrooms and the main source of these particles is likely to be the process of anode changing.



Association of particulate air pollution and acute mortality: involvement of ultrafine particles?

Ultrafine particles are always present in the urban atmosphere and it is suggested that they play a role in causing acute lung injury in sensitive parts of the population.

Number Concentration and Mass Concentration as Determinants of Biological Response to Inhaled Irritant Particles

AbstractParticulate pollutants are mixtures of a variety of chemical species. Sulfuric acid aerosol is a highly irritating component of particulate matter less than 10 μm (PM-10) that can produce

Size analysis of acid aerosols by a metal film technique.

A technique for size determination of acid aerosol droplets by use of vacuum-evaporated metal films, ranging from 0.2 to 0.6 micron thick, which develop reaction spots on exposure to acid aerosols is described.

Dose-dependent effects of submicrometer sulfuric acid aerosol on particle clearance from ciliated human lung airways.

A comparison of the effects of 1 h exposures at 100 micrograms/m3 on the clearance of 7.6 and 4.2 micron particles suggests greater physiological response in distal ciliated airways than in larger central airways.

Sulfate concentrations as an indicator of ambient particulate matter air pollution for health risk evaluations.

It is demonstrated the utility of SO4(2-) as a useful surrogate for ambient PM2.5 and H+ in epidemiological studies and as an index of PM exposure in ambient air quality guidelines and standards.

Effects of inhalable particles on respiratory health of children.

Examination of data from a second cross-sectional assessment of the association of air pollution with chronic respiratory health of children participating in the Six Cities Study of Air Pollution and Health suggests that children with hyperreactive airways may be particularly susceptible to other respiratory symptoms when exposed to these pollutants.

We analyzed the 1980 U.S. vital statistics and available ambient air pollution data bases for sulfates and fine, inhalable, and total suspended particles. Using multiple regression analyses, we

Respiratory hospital admissions and summertime haze air pollution in Toronto, Ontario: consideration of the role of acid aerosols.

Regression analyses indicated that only the O3, H+, and SO4 = associations with respiratory and asthma admissions remained consistently significant after controlling for temperature, indicating that particle size and composition are of central importance in defining the adverse human health effects of particulate matter.

Furnace-generated acid aerosols: speciation and pulmonary effects.

Guinea pigs were exposed to ultrafine aerosols of zinc oxide with a surface layer of sulfuric acid, typical of primary emissions from smelters and coal combustors, to produce decrements in lung volumes and pulmonary diffusing capacity and elevations of lung weight/body weight ratio, protein, and number of neutrophils in pulmonary lavage fluid.
