Several kinds of instruments are available to quantitate fungal propagule levels in air. The tests were conducted at typical conditions observed at the main iodine release points at nuclear power plants. For reproducibility of analytical results of samples deposited on filters using PM 10 sampler , homogeneity of the sample on the filter is very important especially when the size of the X-ray beam for the analysis is less than the size of filter. Most filters yielded fungi prior to suspension in the chambers but only two of 14 nontreated filters demonstrated fungal colonization following use in HVAC systems. However, the Andersen device recovered a broader spectrum of fungi.

Field monitoring venver volatile organic compounds using passive air samplers in an industrial city in Japan. The study demonstrated that the 12 elements tested showed different distribution pattern. In a PUF-based PAS, the PUF disk is generally mounted inside two stainless steel bowls to buffer the air flow to the disk and to shield it from precipitation and light.

The detection limit by 2 hours sampling time is 0. The sintered-fiber media performed much better than sintered-powder media, and the best media had the smallest fiber diameter.

The purpose was twofold: Computational fluid dynamics CFD analyses were performed on a computer-generated model of the sampler for a range of external wind velocities; the results of these analyses were consistent with those from the wind tunnel.

Estimation method can be used for forecast pollutant concentration in future and keep stability of air quality. Aerosol sampling is a complex physical process that depends on many parameters like particle size, wind speed, aspiration velocity and sampler geometry.

However, during tillage 44018 did not present an effect on measured concentrations. The detection was carried out using a Si Li semiconductor detector coupled to a multichannel analyzer, and the X-ray spectra were fitted with the AXIL software. Using a special algorithm we correct the influence of the tailing of the radon progeny to the long lived alpha nuclides and take into consideration possible interference in determining the long lived alpha nuclides.

A miniature critical flow venturi with a constant sampling flow rate of 57 L kpg -1 was developed for application to the new filter air sampler. With regards to the results, it is possible to treat air containing TEA vapor in biotrickling filter. Study on air pollution monitoring in Korea using low volume air sampler by instrumental neutron activation analysis.

The one exception is the high temperature, high efficiency electric air filter. Gent PM sampler was pcp as an integral part of several International Atomic Energy Agency sponsored coordinated research programmes CRP for collecting air particulate samples.

Besides, the HEPA filter is protected from damage by condensed particles or foreign materials entrained; 2 The ''Nuclear-Karlsruhe'' system allows gas-tight filter replacement. The sampling rate SR of the filter4. Both in summer and winter, atmospheric concentrations of OCPs decreased with decreasing height from to 2cm, indicating that OCPs were being deposited from air to soil.

The aerosol size distribution is characterised by the activity median aerodynamic diameter and geometric standard deviation. The Air Sampler AS3 is a portable, user-friendly instrument due to light weight, ruggedness and reliable operation.

When applicating diffusive sampling-systems to workplace air -monitoring it is necessary to know the behaviour of the diffusive-rate and the efficiency in dependence of concentration, exposition time and the type of pollutant.

The scenarios may differ in any unknown, for example the release size or location, weather, mode of building operation, etc.

It is capable of fully automatic sampling of air and gas with denevr adsorption tubes and program-controlled gas flow. In areas supplied with a high efficiency particulate air filtereenver spore levels were usually pl when compared to areas without these filters. We 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.

We present the set-up and a scientific application of the Stratospheric Air Sub- sampler SASa device to collect and to store the vertical profile of air collected with an Air Core Karion et al. Even the PAH profiles differ significantly: There is no direct correlation between the absolute PAH masses found in air samples and those collected by passive samplers or detected in corresponding soil samples.

Storage time of samples almost reaches 44 days. An analytical expression has been derived for the k-sum distribution, formed by summing k random variables from a lognormal population. The airborne particulate matter Dehver -loaded glass fiber filters with an active surface of about cm 2 were weighed and then each filter was cut in five small discs of 6.

Retene, pccl depositing following major wildfires in the region, dominated dissolved PAH concentrations at most Lake Superior sites. The present work presents the characteristic MDA values of the system. This sampler consists of five components.

There was a difference between events on total neonicotinoid concentration collected in particulate matter using either passive or active sampling.
