Aerosol filtration in nanofiber filter media

Nanofiber filter media are used in air filter applications where a compact filtration system with very high overall and fractional efficiency and low initial pressure drop is required. Moreover, because the aerodynamic drag force on nanofibers is very low compared to the drag on the large dust particles collected on the nanofiber media, this media is ideal for application to ...

Application of the Steam Jet Aerosol Collector (SJAC) for differential measurements of organic compounds in the gas vs. particle phase

A modified Steam Jet Aerosol Collector (SJAC) for semivolatile organic compounds has been investigated. Gas phase and particle phase were investigated separately. The SJAC is based on a water condensational growth sampling system. For determination of gaseous compounds an XAD adsorbent cartridge was applied after particle collection. Collection particle efficiency was examined using hydrophobic ...

Control of Aerosol Contaminants in Indoor Air: Combining the Particle Concentration Reduction with Microbial Inactivation

ABSTRACT An indoor air purification technique, which combines unipolar ion emission and photocatalytic oxidation (promoted by a specially designed RCI cell), was investigated in two test chambers, 2.75 m3 and 24.3 m3, using nonbiological and biological challenge aerosols. The reduction in particle concentration was measured size selectively in realtime, and the Air Cleaning Factor and the Clean ...

New laser-based dust emission monitoring system

Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

$Simultaneous determination of PM fractions, particle number and particle size distribution in high time resolution applying one and the same optical measurement technique$

Simultaneous determination of PM fractions, particle number and particle size distribution in high time resolution applying one and the same optical measurement technique

Abstract The Fidas fine dust monitoring systems comprise an optical aerosol spectrometer, which is characterized by very good instrument characteristics, and utilize a sophisticated approach to convert the measured information on particle number and particle size into mass concentrations. As monitoring of PM requires reliable and quality-controlled performance of the measuring systems, ...

Domestic shower hose biofilms contain fungal species capable of causing opportunistic infection

The domestic environment can be a source of pathogenic bacteria. We show here that domestic shower hoses may harbour potentially pathogenic bacteria and fungi. Well-developed biofilms were physically removed from the internal surface of shower hoses collected in four locations in England and Scotland. Amplicon pyrosequencing of 16S and 18S rRNA targets revealed the presence of common aquatic ...

Airborne chemical elements: correlation between atmospheric levels and lichen content

Concentrations of As, Cd, Co, Na, Sb, Se and Zn have been measured in atmospheric particulate matter and Parmelia sulcata Taylor transplants at a suburban and industrial area. Levels in particulate matter were found to be much lower than European target values, Californian Acute Inhalation Reference Exposure Levels and Ontario's Ambient Air Quality Criteria. Correlations between elemental content ...

The Important Job of Oil Mist Collectors

The majority of business owners whose manufacturing process requires machinery that uses coolants, lubricants, or oils know how vital it is to keep the spray or mist released, during the operation from collecting on walls, ceilings or floors as much as possible. Emissions that are uncollected, can lead to slippery surfaces and an unhealthy working environment, which is why an ...

The water environment as a source of potentially pathogenic mycobacteria

Nontuberculous mycobacteria (NTM) are ubiquitous organisms of a wide variety of environmental reservoirs, including natural and municipal water, soil, aerosols, protozoans, animals and humans. Several of these species are potential pathogens which affect human health. The aim of this study was to determine the occurrence of NTM in the water environment. Samples were taken from 13 water-related ...

Cleaning and maintenance management march 2002

While the health risks associated with fluid waste have been known for decades, it wasn’t until the introduction of AIDS into our society that infection control practices and an awareness of the vulnerability to healthcare workers, including custodians, to exposure of bloodborne pathogens, including Heptatities B, became a major concern. Today, a myriad of regulations govern workers’ ...

Mercury spill control procedures - industrial hygiene news

Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury’s hidden danger also lies in when at room temperature, when exposed it vaporizes readily. Once it has become an aerosol, it is absorbed into the lungs and ...

Mercury Spill Control Procedures

Mercury is a dangerous neurotoxin that can have damaging affects on both the central nervous system and renal system of humans. Exposure to mercury can cause serious developmental delays in children, and high level exposure is life threatening. When exposed to air, mercury vaporizes, readily becoming a dangerous aerosol that can be absorbed into the lungs and spread throughout the body. This is ...

Least-Cost Approaches to Reducing Acid Emissions

' The costs of meeting sulfur emission targets can be high. It is essential, therefore, that countries adopt policies which (a) minimize the net economic and social costs of reducing emissions to the agreed target levels, and (b) maximize the overlap between measures designed to reduce acidifying emissions and those addressing other forms of air pollution. This note discusses alternative ...
