Dr. Kevin Perry has more than 23 years of management and research experience in the areas of ambient air quality monitoring, instrumentation/analytical technique development, source apportionment, atmospheric dry deposition, and the climatic and health effects of particulate matter. (utah.edu)

As the percentage of dust in the air increases, so do hospital visits for respiratory complications, as well as dust-borne diseases such as Valley Fever and meningococcal meningitis. (salon.com)
33 Occurrences of WTC respiratory disease in rescue workers/volunteers whose first exposure was more than 48 hours post-collapse could be explained either by "high-level" exposures generated by activities that disturbed dust in place, while entering enclosed, poorly ventilated areas, or by the accumulation of repeated "low-level" exposures over time. (cdc.gov)
Children, older adults and individuals with compromised immune systems and respiratory and cardiovascular conditions are particularly vulnerable, and are advised to wear well-fitting N95 masks if they must go outdoors, to reduce exposure to fine particles. (baltimoresun.com)
Only sparse data are available as to the respiratory morbidity that may be associated with these small particles. (medscape.com)

and mineral dust. (who.int)

1 , 4 , 5 , 6 , 7 Contaminants such as asbestos, hydrochloric acid, PCBs (Polychlorinated biphenyls), silica and heavy metals were found in the dust and ash resulting from the WTC collapse. (cdc.gov)
McGrath, 73, grew up in Butte and has long been one of the voices in the neighborhood asking whether the dust that settles on his roof and car includes a dangerous mix of toxic metals. (flatheadbeacon.com)
Solids are either finely divided dust particles such as fromgrinding operations, or as still more finely divided metal fume particles asgenerated when smoldering hot metals vaporize. (safety-video-bmsh.com)

Air monitoring results in 2021 from EPA stations across Ireland show that fine particulate matter (PM2.5), mainly from burning solid fuel in our homes, and nitrogen dioxide (NO2) mainly from road traffic, remain the main threats to good air quality. (irishheart.ie)

It can be wet precipitation (rain, snow, or fog) or dry precipitation (absorbed gaseous and particulate matter, aerosol particles or dust). (photius.com)

At the beginning of 2013, fog and thunder swept the whole Middle East of China, among which Beijing Tianjin Hebei region was the most polluted, and the daily average fine particle PM 2.5 concentration was as high as 500 μ g/m 3 . (hindawi.com)

To obtain high efficiency removal of 1 micrometer (or less) particles generally requires high-energy devices such as venturi scrubbers or augmented devices such as condensation scrubbers. (wikipedia.org)
It was confirmed that the half masks of the FFP2 class are capable of filtering submicrometer aerosol in particle size range 7 to 270 nm with an efficiency exceeding 96% and can contribute to achieving compliance with the OEL for DE in the mining sector. (bvsalud.org)

Concern was expressed over employee/inmate exposures to isopropyl-alcohol (67630), toluene (108883), methylene- chloride (75092), nuisance particulate matter, wood dust, iron-oxide (1309371), and welding fumes from furniture refinishing. (cdc.gov)
Quantitative determination of trucking industry workers' exposures to diesel exhaust particles. (who.int)

Dust is a growing concern for a number of reasons. (salon.com)
Traffic accidents are also a growing concern across the western U.S., where dust affects road visibility. (salon.com)

Recent research suggests PM 0.1 particles are sources of oxidative stress and cardiovascular toxicity . (medicalnewstoday.com)

NaCl aerosol in the particle size range of 7 to 270 nm was used for tests. (bvsalud.org)
Aerosol penetration was a function of particle size. (bvsalud.org)

The saturator removes a small percentage of the particulate matter present in the flue gas. (wikipedia.org)
If you rely on the possibility of the particulate matter measuring device being combined with flue gas analyzers , attention should preferably be paid to compatibility when making a selection. (testo.com)

A low volume, high velocity exhaust system is recommended which uses small volumes of air at high velocities to control dust from portable hand tools. (cdc.gov)
A wet scrubber's ability to collect small particles is often directly proportional to the power input into the scrubber. (wikipedia.org)
Real dust is a complex matrix of components including dust mites, dust mite faeces, bacteria, mould, small insects and particles. (dyson.co.uk)
We also want to make sure that the air being expelled from the vacuum is clean - in fact, Dyson machines can capture 99.97% particles as small as 0.3 microns. (dyson.co.uk)
The air quality sensor on the AirLink Professional Air Quality Monitor can measure particulates as small as 0.3 microns with a concentration accuracy of +/- 10 micrograms per cubic meter. (davisnet.com)
Fine particulate matter, or PM 2.5 , is so small that it cannot be seen in the air. (cdc.gov)
As a result, the amount of small dust particles (particulate matter) in the air increases. (atlasleefomgeving.nl)
Small particles are only regulated on a 24-hour and annual average, while large particles are regulated on an hourly basis. (earthjustice.org)
