Seven (7) boxes of shells, with a total of one hundred five (105) shells, were delivered to MVA Scientific Consultants on 17 October 2019 via UPS and assigned the MVA laboratory identification numbers AE1386 through AE1392 (Figures 1 through 8). A currentlyavailable box of Remington shells was purchased on 28 October 2019 for comparison to the vintage shells and for use during setup of the experiment. This sample was assigned MVA laboratory identification number AE1446. Sample numbers and descriptions of the shell types investigated are provided in Table 1. The lot number printed on box AE1389 is difficult to read; however a photograph is provided in Figure 3. The dram equivalent amount has been torn off of box AE1392; however, the shell is a Magnum style, so therefore is it assumed to carry no more than the 4% dram listed for AE1389, a 3" long Magnum shell. It was requested that components of the shells be analyzed for the presence of asbestos and that a study be performed to gain information about the concentration of asbestos in the air, if any, during the discharge of asbestos-containing shotgun shells. The experiment was performed on 29 October 2019. Peter Diaczuk, Ph.D., a certified firearms instructor and forensic science consultant with Pedico Research Institute, Waymart, PA oversaw handling and firing of the shotgun. Mr. Chris DePasquale, CIH, of Compass Environmental, Kennesaw, GA, collected air samples during the study with the assistance of Steven Compton, Ph.D., of MVA Scientific Consultants. Abatement contractors from Branch Environmental Inc., Watkinsville, GA assembled the chamber utilized during the experiments. Sample numbers for the air samples collected during the activities are shown in Table 2. Laboratory analyses for the study (including examination of shell components and of air samples) were performed in the MVA laboratory during the period of 17 October 2019 through 27 February 2020. Sample Description (Shotgun Shell Basewads) A standard shotgun shell consists of a metal base with a primer, propellant (gun powder), shot (projectile/s), a wad to separate the powder from the shot, and a plastic casing attached to the base and crimped at the opposite end to hold it all together [1]. The metal base or "head" may also contain a filler material referred to as the basewad in the 1966 patent assigned to the Remington Arms Company [2]. This report will refer to the wad separating the powder/propellant from the shot as the "powder wad" in order to avoid confusion with the basewad, shot wad (a plastic cup sometimes used to contain the shot), or overshot wad (sometimes placed over the shot before crimping the case) [3]. 13129report030220.docx WJi V S 4 MCVOANSSCU|ELTNATN|FT|CS Full Service AnalyticalMicroscopy Laboratory Page 2 of 43 Methods One shell from each box was selected at random for analysis. Each shell tested was carefully dissected using a stainless steel razor blade. Wad components (from basewads and powder wads) were examined visually and under an Olympus SZ40 stereomicroscope at magnifications from 7X to 40X. For each component tested, a portion of the material was transferred via forceps onto a microscope slide and mounted in Cargille refractive index liquids for analysis by polarized light microscopy (PLM) using an Olympus BHSP polarized light microscope with a magnification range from 100X to 1,000X. The PLM analysis followed the analytical procedures recommended by the U.S. Environmental Protection Agency [4]. The PLM results for asbestos are given in terms of percent by volume. During the experiments, airborne particles were collected with standard asbestos testing air filter cassettes. The air samples and two field blanks were analyzed using a combination of phase contrast microscopy (PCM) and transmission electron microscopy (TEM) asbestos testing methods, including one or more of the following: EPA AHERA method [5], ISO 10312-2019 method [6], NIOSH 7400 method [7], and NIOSH 7402 method [8]. TEM analyses were performed using either a Philips EM420 100 kV transmission electron microscope (TEM) capable of selected area electron diffraction (E S) (SAED) and equipped with a Thermo Scientific Noran System 7 energy dispersive spectrometry d x-ray analysis system or a Philips CM120 100 kV TEM capable of SAED and equipped with an Oxford INCA EDS system. TEM count sheets are provided in the Appendix. Study Site All studies were conducted in a specially built negative air enclosure (test chamber) in an open air basement located at a farm house in rural Farmington, GA. The test chamber work area was approximately 8 ft high by 14 ft wide by 15 ft long. The study area had a High Efficiency Particulate Absolute (HEPA) air filtration device which was used to maintain air flow within the chamber and to filter the air as it was removed from the chamber before, during, and after the experiments. The HEPA unit ran at a low flow rate (approximately 314 cubic feet per minute) during each of the experiments and a high flow rate (approximately 511 cubic feet per minute) between the experiments. While inside the study area between tests, Mr. DePasquale and Dr. Compton each wore a respirator and complete head and body protective suit. Shells were fired using a Remington 1100, 12 gauge, semi-automatic shotgun mounted onto a Lead Sled DFT 2 from Caldwell Shooting Supplies and equipped with a manual trigger pull (string) to allow for remote firing of the shotgun from outside the chamber. The shotgun was positioned to fire into a custom built target manufactured from ballistic rubber and steel to ensure that the shots were safely collected. Five stationary air sampling pumps were utilized to collect air samples before and during the experiments. Four of the pumps were used to collect air samples at different locations within the study chamber, as shown in Figure 9. Air samples collected using Pump #01 were positioned within the breathing zone of a theoretical shooter (no shooter was present in the study chamber during firearm discharge), approximately 24" behind the shell ejector port. Air samples collected using Pump #02 were positioned 12" from the WJi V S i MVA SCIENTIFIC CONSULTANTS Full Service AnalyticalMicroscopy Laboratory 13129report030220.docx Page 3 of 43 muzzle exhaust (end of the barrel) and 36" downrange from the shell ejector port. Air samples collected using Pump #03 were positioned approximately 12" from the shell ejector port. Air samples collected using Pump #04 were set-up to replicate the position of a bystander standing three feet from the shooter. Air samples collected using Pump #05 were positioned outside of the containment within a few feet of the study chamber entry. After the experiments were conducted, the flow rate of Pump #03 had fallen outside of the acceptance range, so the results for those air samples are reported as a range based on the minimum and maximum flow rates recorded instead of an average flow rate. The study was videotaped. During certain portions of the study, the lighting approximated Tyndall lighting and was used to improve the visibility of suspended particles in the air in the containment chamber. The light was placed outside the test chamber. Study Design Prior to the experiments with any asbestos-containing shells, three preliminary air samples were collected within the test chamber (in the vicinity of a shooter's breathing zone). The first preliminary air sample was collected the day before the experiments were conducted by firing five modern shells (AE1446) over a period of fifteen minutes. The air sample was collected at a flow rate of 10.0 liters per minute (LPM). This air sample was visually determined to be overloaded with gunshot residue. On the morning of the experiment, one air sample was collected for a period of 15 minutes (at 10.0 liters per minute) without any shots fired. The flow rate of the pump was reduced to a flow rate of 5.07 LPM and a second air sample was collected over a fifteen minute period while firing two modern shells (AE1446). Visual loading of the filter appeared acceptable, so these parameters served as the parameters to be used for the experiments performed on three types of Remington shells. The first experiment performed involved firing two shells from the Remington ShurShot style shell (AE1386). One shell was discharged at the beginning of the air sampling period and a second approximately halfway into the experiment. After the pumps were turned off, the flow rate for the HEPA unit was increased to purge the air for eight minutes and the air cassettes from Test A were recovered. After returning the HEPA unit back to a lower flow rate, an air sample was collected using Pump #01 to investigate the concentration of asbestos present in the air between Test A and Test B. After this "between-test" air sample was collected, new air cassettes were prepared for Test B and the shotgun was loaded with two shells from the Remington Magnum Express style shell (AE1392). One shell was discharged at the beginning of the sampling period and the second discharged approximately 11 minutes into the experiment after manually loading the next shell into the chamber. After the pumps were turned off, the flow rate for the HEPA unit was increased to purge the air for six minutes and the air cassettes from Test B were recovered. After returning the HEPA unit back to a lower flow rate, an air sample was collected using Pump #01 to investigate the concentration of asbestos present in the air between Test B and Test C. 13129report030220.docx WJi V S 4 MCVOANSSCU|ELTNATN|FT|CS Full Service AnalyticalMicroscopy Laboratory Page 4 of 43 After this "between-test" air sample was collected, new air cassettes were prepared for Test C and the shotgun was loaded with two shells from the Remington Express style (AE1390). One shell was discharged at the beginning of the sampling period and the second discharged approximately halfway into the experiment. After the pumps were turned off, the flow rate for the HEPA unit was increased to purge the air for 10 minutes and the air cassettes from Test C were recovered. After returning the HEPA unit back to a lower flow rate, an air sample was collected using Pump #01 to investigate the concentration of asbestos present in the air between Test C and Test D. After this "between-test" air sample was collected, new air cassettes were prepared for Test D and the shotgun was loaded with eight shells from the Remington Express style (AE1390). One shell was discharged at the beginning of the sampling period and at two minute intervals thereafter over a 16 minute sampling period. Results and Discussion Results of basewad analyses are summarized in Table 1. All seven vintage shell types analyzed contained a basewad constructed of a filler material (some combination of chrysotile asbestos and cellulose/wood fiber) and a waxy binder. The concentration of asbestos ranged from 10% to 15% on average. Asbestos was not detected in any of the powder wads. Filler materials for powder wads were composed primarily of cellulose. Photographs documenting the dissection of each shell and micrographs collected during examination of the basewads are provided in Figures 10 through 30. Additional bulk analysis was performed on the basewad of a shell from set AE1390 after it was fired in the experiment. The fired shell shows some fracturing and spalling of the basewad, which demonstrates the effect of firing on the basewad. Gunshot residue was deposited in flakes, spheres and a partial coating, but unencapsulated chrysotile bundles were still visible. Photographs documenting the fracturing and spalling of the basewad are provided in Figures 31 and 32. The mass of recovered basewad material from an unfired AE1390 shell was measured at approximately 3.58 grams. The mass of recovered basewad material from a fired AE1390 shell was measured at approximately 3.52 grams, a difference of 0.06 grams; however, additional testing would be required to determine whether this mass difference is greater than any potential variability in mass from unfired basewads. Still images taken from the video, provided in Figures 33 and 34, demonstrate the propagation of dust resulting from the discharge of the firearm and the ejection of the shell. Results of NIOSH air sample analyses are summarized in Table 3. NIOSH 7400 concentrations from the breathing zone of a shooter (Pump #01) range from 0.11 to 0.23 fibers per cubic centimeter of air sampled (f/cc). These values represent concentrations from PCM analyses only and do not independently discriminate asbestos fibers from other fibers present in the air. Typically, a complementary analysis via TEM using NIOSH 7402 can be applied to establish an estimated asbestos f/cc concentration; however, in this study the NIOSH 7402 results were highly variable, with some samples indicating 0% asbestos and some indicating 100% asbestos. If the results of all air samples are combined, an average of 35% of the fibers identified by WJi V S i MVA SCIENTIFIC CONSULTANTS Full Service AnalyticalMicroscopy Laboratory 13129report030220.docx Page 5 of 43 TEM were consistent with asbestos, thus resulting in a breathing zone range of 0.04 to 0.08 asbestos f/cc. The variability in the 7402 results can be attributed to the presence of aluminum silicate fibers in the background air and non-fibrous gunshot residue (GSR). In addition, several asbestos fibers observed via TEM were not countable under NIOSH 7402 because they were below the minimum width cutoff of 0.25 micrometers. Aluminum silicate fibers were detected in air samples both inside and outside the test chamber (i.e. Pump #05). A micrograph and spectrum of a representative aluminum silicate fiber bundle are provided in Figure 35. The detection in air samples from outside of the containment area indicates that these fibers were present in the ambient air and were not the result of experimental testing. For NIOSH 7402 analyses, these fibers were counted as "non-asbestos" fibers since they are inconsistent with the elemental composition of chrysotile fibers under investigation in this test. Air samples from within the testing chamber for all four experiments also contained a background of very fine non-fibrous gunshot residue particulate. A micrograph and EDS spectrum of non-fibrous GSR near a chrysotile fiber bundle are provided in Figure 36. Samples from Test D had a higher level of background GSR, due to the increased number of shots, and it is possible that some fibers were obscured by heavily-loaded non-fibrous GSR and therefore not detected. The NIOSH 7402 analysis is designed to serve as a correction factor to PCM fiber counts obtained using NIOSH 7400. The use of the method assumes that fibers thinner than 0.25 micrometers in width cannot be detected by PCM and therefore are not counted in the 7402 TEM method, even if they are detected. Therefore, in samples such as these where such fibers and fiber bundles are prevalent, the 7402 correction factor may not be the most accurate representation. Because of these three issues, air samples from each experiment were also analyzed using either the EPA AHERA method or the ISO 10312 method, since both methods allow for a count of true asbestos fibers without a minimum width and without counting aluminum silicate fibers from the background air. A summary of the AHERA/ISO 10312 TEM results is provided in Table 4. Chrysotile fibers and bundles were detected by TEM in chamber air samples in each of the four experiments. Micrographs and spectra of chrysotile fibers and bundles detected in the air samples are provided in Figures 37 through 40. Airborne asbestos structure concentrations for the shooter were 1.4 str/cc and 1.0 str/cc in the first and second tests, respectively. Prior to Test C, a residual concentration of 0.6 str/cc was detected, and an increased concentration of 2.5 str/cc was detected during Test C. Prior to Test D, a residual concentration of 0.37 str/cc was detected and an increased concentration of 1.98 str/cc was detected during Test D. Because the "between-test" air samples are averages of an ever diminishing airborne concentration (due to the active purging of air from the negative air machine), it can be assumed that the actual concentration present in the air at the start of the subsequent test must be less than the average concentration reported for the "between-test" sample. It is therefore a conservative statement to say that the baseline-corrected breathing zone concentrations are 1.4, 1.0, 1.9, and 1.6 str/cc, respectively for each of WJi V S i MVA SCIENTIFIC CONSULTANTS Full Service AnalyticalMicroscopy Laboratory 13129report030220.docx Page 6 of 43 the four tests. For a bystander, approximately three feet from the shooter, airborne asbestos concentrations were detected at levels of 0.3, 1.4, 1.3, and 0.25 str/cc. A similar conservative baseline-corrected approach as described above would suggest concentrations of 0.3, 1.4, 0.7, and <0.25 str/cc respectively. Conclusions Chrysotile fibers present in the basewad of vintage Remington shotgun shells make up approximately 10% to 15% (by volume) of the basewad material. Asbestos fibers from the basewad are aerosolized when the shell is discharged. Airborne asbestos fibers were detected in each of the four experiments conducted. Asbestos fiber structures present in the breathing zone of a shooter ranged from 1.0 to 2.5 str/cc (1.9 str/cc after baseline correction). For a bystander three feet from the shooter, the airborne asbestos concentration ranged from 0.25 to 1.4 str/cc. The range of fibers reported for the shooter via NIOSH 7400/7402 (fibers greater than 5 micrometers in length) is variable; however, it is estimated to be approximately 0.04 f/cc to 0.08 f/cc.
