The different experimental electric filters described in this report include prefilters for use in glove boxes and in ventilation systems, re-circulating air filters , electric HEPA filters , and high efficiency, high temperature air filters. We present a mechanically coupled MEMS H resonator capable of performing simultaneous amplification and filter operation in air. The viruses were extracted at much lower efficiencies 0. Significantly less PAHs were quantified in SPMDs deployed in the cage chamber and open box chamber compared to samplers from the other two chambers, suggesting that photodegradation of PAHs had occurred. The effects of climate in particle size, composition and concentration were considered in terms of precipitation and wind intensity, but they are actually minor.

Comparative performance of two air samplers for monitoring airborne fungal propagules. Ozone concentrations showed little county to county variation, except Iredell and Cabarrus which had higher concentrations than Rowan.

The detection was carried out using a Si Li semiconductor detector coupled to a multichannel analyzer, and the X-ray spectra were fitted denveg the AXIL software. Samples were analyzed using spectrophotometry and ion chromatography. The new analytical system is capable of quantifying a wide suite of C2 to C10 organic compounds at part-per-trillion sensitivity.

It provides easy filter changing, constant flow sampling, and a visual display to indicate proper operation. Analyses showed a high level of microbial air contamination in the examined production areas in relation to the guidelines applied in the assessment of indoor air contamination. Air filters are expected to achieve certain performances within their duty, viz.

This paper reports on a field trail in which outdoor air was sampled with an active reference sampler and several passive HTO-in- air samplers simultaneously carried out at Chalk River Laboratories. The profiles of several elements are shown and the results are discussed. These simple samplers consist of a standard mL liquid scintillation vial with a diffusion orifice that determines the sampling rate.

Using the PAS, the atmospheric 4108 phase organochlorine pesticides OCPs at 11 heights from close-to-surface 2cm to pl above ground, in summer and in winter, were measured. The air is drawn through the sampler by means of a diaphragm vacuum pump, which is enclosed in a special housing together with a needle valve, vacuum gauge, flow meter, volume meter, time switch for interrupted sampling and hour meter.

The sampling efficiency of MNV was significantly influenced by both sampler and filter ppcl. Preliminary results from a long-term study in southern Norway are presented.

Emphasis is mainly placed on so-called high-efficiency particulate air filters HEPA filters and on providing general information on them. The results of the bubblers are used to calibrate the free hanging filters.

The sintered-fiber media performed much better than sintered-powder media, and the best media had the smallest fiber diameter. The objective of our study was to assess if dust fall filters can serve as passive air samplers and be used to characterize potential exposures in a community near contaminated mine tailings.

An experimental study was conducted to characterize the collection efficiency of the sampler as affected by variations in room air velocity, particle size, sampling flow rate, inlet geometry, and inlet orientation to the free stream. Based on the recorded results, it was recommended to undertake immediate corrective actions, consisting in the replacement of filters in the refrigeration and air conditioning equipment, as well as to provide comprehensive training for the employees working in the selected facilities.

In recent years, fluctuations in the price of crude oil and corresponding fluctuations in the price of gasoline and diesel fuels have renewed interest in vehicle fuel economy in the United States. Both laboratory and field test results are presented. Retene, probably depositing following major wildfires in the region, dominated dissolved PAH concentrations at most Lake Superior sites.

The impaction method showed the applicability of the air sampler in in-situ measurements. A characteristic of the free filter is the Sampling Volume, SV.

Using hypothetical scenarios, values of contact exposure for a honey bee were estimated to be in the range from 1. Herein, we report a portable battery-powered sampler that is capable of highly efficient bioaerosol collection.

The plume from the Chernobyl nuclear reactor reached London in the morning of 1st May. Different PAH concentrations were denvef in air masses from different directions in the field test. These rates were then used to estimate the occupational exposure of firefighters and police forensic specialists to 32 PAHs.

Denvee algorithm also can optimize sampler placement in the face of modeling uncertainties, for example the airflow leakage characteristics of the building, and the detection capabilities of the samplers. Experimental typing of the entry efficiency in calm air of an annular slot sampler ; Determination experimentale de l’efficacite de captage en air calme d’un echantillonneur a fente annulaire.

Moreover, mixed-frequency excitation is used to demonstrate a tunable wide band filter for low frequency applications. The potential of passive air sampling devices polyurethane foam disks to assess the influence of local sources on the quality of the surrounding environment was investigated.

The authors have, in cooperation with industry, developed high-efficiency filters made from sintered stainless-steel fibers for use in several air -cleaning applications in the nuclear industry. As fabricated, each source consisted of an outer stainless steel housing, an inner Ba impregnated polyester liner, 4 weight percent silver steel lid.
