“…The inlet of this sampling train was restricted to provide a casette inlet and filter face velocity equivalent to that of a conventional 37-mm filter cassette operated at a flow rate of 2 l/min (13). The collection characteristics of this system were shown to be comparable to those of the conventional method (7).…”

LANDRIGAN PJ, COSTELLO RJ, STRINGER WT. Occupational exposure to arsine: An epidemiologic reappraisal of current standards. Scand j work environ heaLth 8 (1982) 169-177. In an evaluation of chronic occupational exposure to arsine (AsHg), an epidemiologic survey was conducted at a lead-acid battery manufacturing plant. Personal (breathing zone) air samples were obtained for the measurement of exposure to arsine and particulate arsenic (As), and area air samples were also collected for the determination of arsenic trioxide (AS20g) vapor concentrations. For the quantification of arsenic absorption, total arsenic content was determined in duplicate 24-h urine samples. Arsine in 177 breathing-zone air samples ranged from nondetectable to 49 ,ug/m 3 . The highest levels were found in the battery formation area, where arsine is generated by the reaction of battery acid with lead-arsenic alloy. 'Exposures to particulate arsenic (maximum 5.1 ,ug/m 3 ) and to AS20g (maximum 0.44 ,ug/m 3 , expressed as As) were generally lower. Urine analysis showed that eight (20.5 0/0) of 39 production workers had urinary arsenic concentrations (corrected to a specific gravity of 1.024) of 50 ,ug/l (0.67 ,umol/l) or above, indicating increased arsenic absorption. None of eight office staff had elevated urinary arsenic levels. A close correlation was found between urinary arsenic concentration and arsine exposure (N = 47; r = 0.84; P = 0.0001). Arsine levels above 15.6 flg/m 3 were associated with urinary arsenic concentrations in excess of 50 ,ug/l (0.67 flmol/l). No correlation was found between urinary arsenic content and exposures to particulate arsenic or to AS20g. Consumption of neither seafood, red wine, tobacco, nor contaminated drinking Water accounted for urinary arsenic excretion. It was concluded that the current arsine exposure standard, 200 flg/m 3 , fails to prevent chronic increased absorption of trivalent arsenic from the inhalation of arsine.

“…Many OSHA and NIOSH sampling and analytical methods for pesticides require the use of the OVS, including OSHA Analytical Methods 62 and 63 and NIOSH Methods 5600, 5601, and 5602. The OVS can measure aerosols and vapors simultaneously, and is similar in concept to the Hill and Arnold air sampler for pesticides [17]. [18].…”

Many occupational diseases are associated with where particles penetrate and deposit in the three major regions of the respiratory tract. Sampling criterion has been developed for particles that enter the nose and/or mouth (inhalable aerosols). Pesticides can exist as both gases (vapors) and particles simultaneously in air. The Institute of Occupational Medicine (IOM) sampler was designed to sample for inhalable-sized particles, while sorbent tubes are used to sample for vapors. The OSHA Versatile Sampler (OVS) can measure aerosols and vapors simultaneously, and many sampling and analytical methods for pesticides require the use of an OVS. The American Conference of Governmental Industrial Hygienists (ACGIH) has established an IFV (inhalable fraction and vapor) endnote for chemicals that need to be evaluated for both inhalable fraction and vapor due to their volatility. Pesticides make up the majority of Threshold Limit Values v PUBLIC ABSTRACT Many occupational diseases are associated with where particles penetrate and deposit in the three major regions of the respiratory tract. Sampling criterion has been developed for particles that enter the nose and/or mouth (inhalable aerosols). Pesticides can exist as both gases (vapors) and particles simultaneously in air. The Institute of Occupational Medicine (IOM) sampler was designed to sample for inhalable-sized particles, while sorbent tubes are used to sample for vapors. The OSHA Versatile Sampler (OVS) can measure aerosols and vapors simultaneously, and many sampling and analytical methods for pesticides require the use of an OVS. The American Conference of Governmental Industrial Hygienists (ACGIH) has an IFV (inhalable fraction and vapor) endnote for chemicals that need to be evaluated for both inhalable fraction and vapor due to their volatility. Pesticides make up the majority of Threshold Limit Values having an IFV endnote. However, the OVS is not recognized as an inhalable sampler, and there is no published literature on the particle-phase collection efficiency of the OVS. The purpose of this study was to evaluate the performance of the OVS and compare its performance to the IOM inhalable sampler and to modify the OVS to sample similarly to the IOM sampler. The results of this study show that the OVS under-samples when compared to the IOM sampler, and none of our modifications made any significant improvements to the original configuration of the OVS. Further research should include developing an inhalable particle and vapor personal sampler that is commercially available in the United States.
