“…This may be partly due to the orientation of the CFC sampler in which its inlet hole faces downward. This finding is in agreement with results of Görner et al (2010) and Buchan et al (1986) who measured the aspiration efficiency of the CFC sampler at various angles of inclination in a laboratory study as well as with results from Skaugset et al (2013) obtained in a field study carried out in the aluminium industry.…”

“…Many laboratory and field studies carried out in various industrial environments have shown that measurements of inhalable concentrations are generally higher than those made when using the ‘total’ particulate (CFC) method. In the papers of Werner et al (1996) , Davies et al (1999) , and Skaugset et al (2013) , where the IOM sampler was used for inhalable sampling, mean conversion factors from 1.2 up to 4.2 were reported depending on the coarseness of the workplace aerosol monitored. There are also field studies dedicated specifically to Be comparing different sampling methods.…”

A field study was carried out in order to derive a factor for the conversion of historic worker exposure data on airborne beryllium (Be) obtained by sampling according to the 37-mm closed faced filter cassette (CFC) ‘total’ particulate method into exposure concentration values to be expected when sampling using the ‘Gesamtstaubprobenahmesystem’ (GSP) inhalable sampling convention. Workplaces selected to represent the different copper Be work processing operations that typically occur in Germany and the EU were monitored revealing a broad spectrum of prevailing Be size distributions. In total, 39 personal samples were taken using a 37-mm CFC and a GSP worn side by side for simultaneous collection of the ‘total’ dust and the inhalable particulates, respectively. In addition, 20 static general area measurements were carried out using GSP, CFC, and Respicon samplers in parallel, the latter one providing information on the extra-thoracic fraction of the workplace aerosol. The study showed that there is a linear relationship between the concentrations measured with the CFC and those measured with the GSP sampler. The geometric mean value of the ratios of time-weighted average concentrations determined from GSP and CFC samples of all personal samples was 2.88. The individual values covered a range between 1 and 17 related to differences in size distributions of the Be-containing particulates. This was supported by the area measurements showing that the conversion factor increases with increasing values of the extra-thoracic fraction covering a range between 0 and 79%.

“…Personal dust samples were taken in the workers breathing zone using 25-mm three piece, closed-faced conductive cassettes (Millipore MAWP 025 AC) with a cellulose acetate filter (Millipore AAWP02500) attached to Side Kick Casella pumps with a flow rate of 2 l min −1 ( Occupational Safety and Health Administration, 2014 ). This sampling head has the same geometry (except for the cassette diameter) and orifice diameter as the 37 mm three-piece cassette used for ‘total’ dust sampling, and has also been assumed to sample ‘total’ dust at a flow rate of 2 l min −1 ( Skaugset et al ., 2013 ). The pumps were paused during lunch breaks.…”

BackgroundCoffee processing has been shown to cause high dust exposure among the workers, but there are few studies from primary processing of coffee, and none of them is from Ethiopia. The aim of this study was to assess dust exposure and its determinants among workers in primary coffee processing factories of Ethiopia.MethodsA total of 360 personal ‘total’ dust samples were collected from the breathing zone of workers in 12 primary coffee processing factories in Ethiopia. Dust sampling was performed with 25-mm three piece conductive cassettes with cellulose acetate filters attached to pumps with flow rate of 2 l min−1 for an average sampling duration of 410 min. The dust samples were analysed gravimetrically using a standard microbalance scale. An observational checklist was used to collect information about possible determinants of dust exposure in the work environment. Linear mixed effect regression models were used to identify significant determinants of total dust exposure.ResultsPersonal total dust exposure levels varied between the three main job groups with a geometric mean (GM) of 12.54 mg m−3 for the machine room workers, 12.30 mg m−3 for the transport workers, and 1.08 mg m−3 for hand pickers. In these three groups, 84.6%, 84.1% and 2.6% of the samples exceeded the occupational exposure limit for organic total dust of 5 mg m−3, respectively. The mixed-effects model for the machine room workers explained 21% of the total variance in total dust exposure, and showed that vigorously pouring coffee from a dropping height was associated with an about two times increase in exposure. For the transport workers, the mixed-effects model that included pouring method of coffee beans, number of huller machine in the room, mixing coffee, and feeding hopper explained 32% of total variance in personal total dust exposure.ConclusionAbout 84% of the dust samples among machine room and transport workers in primary coffee processing factories were above the occupational exposure limit value for organic dust. Proper control measures are necessary to reduce the exposure.

“…The IOM dual sampler, which measures both the inhalable and respirable fractions has been used in three publications [ 28 , 29 , 37 ]. In addition, two publications [ 40 , 41 ] have used the Respicon sampler to analyse the inhalable, respirable and thoracic fractions and one publication has used the Respicon sampler to analyse the inhalable and thoracic fractions [ 42 ].…”

We provide a narrative review on published peer-reviewed scientific literature reporting comparisons of personal samplers in workplace settings published between 2004 and 2020. Search terms were developed for Web of Science and PubMed bibliographic databases. The retrieved studies were then screened for relevance, with those studies meeting the inclusion criteria being taken forward to data extraction (22 studies). The inhalable fraction was the most common fraction assessed with the IOM sampler being the most studied sampler. The most common workplace environment where samplers had been compared was that where metals/metalloids were present. The requirements of EN13205 standard (Workplace exposure. Assessment of sampler performance for measurement of airborne particle concentrations) have also been considered, with these requirements not currently being met, or at least referred to, in the included published literature. A number of conclusions have been drawn from this narrative review. For studies that reported correction factors, no discernible trends could be identified. Correction factors also varied between samplers and settings, with correction factors varying from 0.67 for Button/IOM in agriculture settings to a correction factor of 4.2 for the closed face cassette/IOM samplers in aluminium smelters. The need for more detailed and informative data sharing from authors is highlighted, providing more context to both the sampling strategy and methodology, as well as the data analysis. It is recommended that the requirements of EN13205 are taken into account when designing sampler comparison studies at the workplace and that these are also reported. It is also considered that there is a need for a clear standardized workplace sampler comparison protocol to be developed, which can be used by the research and occupational hygiene community to allow more robust and transparent assessment of aerosol samplers and better-quality evidence for use by industrial hygienists, epidemiologists, and occupational safety specialists alike.
