The daily exposure concentrations ranged from 8 to 43 mg/m3 (average 22 mg/m3) for the low exposure concentration. Affleck, R.L. No dose-related increases were seen in any malformation or variations. Chemical Characterization and Toxicologic Evaluation of Airborne Mixtures, Final Report. The mean daily exposure duration was 8 min. Data from the rat and dog indicate a LOAEL for respiratory distress at an exposure concentration of approximately 1,200 mg/m3 for 1 to 1.5 hr (Table 4-3). 1988b. Sie sind einfach zu verwenden und versprühen etwa 160 BBs. No. To extend this exposure level to the general population requires the incorporation of an additional uncertainty factor of 10, because the general population might include individuals who are more sensitive to such exposures than are healthy workers. Production was started immediately and at an accelerated rate. ACGIH (1991) observed that the TLV-TWA is below the concentration that causes throat irritation among unacclimated workers, TABLE 4-4 ACGIH Recommended Exposure Limits. Seven of those had significant laryngeal and tracheal lesions that consisted of a fine fibrinlike coat on the laryngeal and proximal tracheal mucosa. 1988a; Lundy and Eaton 1994), indicating that the macrophages returned to their normal state within 8 weeks of exposure. 1985. AD-A102678. You're looking at OpenBook, NAP.edu's online reading room since 1999. 76 special incendiary grenade also commonly known as the A.W. Due to its poly-meric nature, red phosphorus is practically insoluble in water. Neurobehavioral Effects. Weimer et al. White phosphorus has been used for military purposes as a source of smoke and to fill incendiary shells and grenades. The subcommittee recommends that the Army conduct a prospective study with appropriate controls in which pulmonary-function tests and routine chemistry tests (panel 20 plus Mg and thyroid tests as a minimum requirement) are performed on personnel who are exposed repeatedly to the smoke. A significant increase in the protein level in the pulmonary lavage fluid of rats of both sexes after exposure to more than 1,000 mg/m3 indicated pulmonary edema, which was resolved during the recovery period (Aranyi 1984). Cederwall, and L.B. IIT Research Institute, Chicago. At the high exposure concentration, the cumulative CT was 81,691 mg•min/m3; the mean daily exposure CT was 1,319 mg•min/m3, and the mean daily exposure duration was 8 min. Finally, the subcommittee notes that Army personnel who work with this smoke, trainers in particular, are potentially a rich source of information on the health effects of the smoke. 1988a). How to Obtain Red Phosphorus The strike face of matches contains red phosphorus. In the 13-week exposure paradigm, increased cellular ATP levels occurred at the lowest exposure concentration tested (300 mg/m3), but decreased activity of 5'-nucleotidase occurred only at exposure concentrations of 750 mg/m3 or higher (Aranyi et al. Based on feedback from you, our users, we've made some improvements that make it easier than ever to read thousands of publications on our website. Histologically, the primary exposure-related change seen after termination of the studies was the presence of terminal bronchiolar fibrosis, resulting in a thickening of the alveolar walls and of the most distal portions of the terminal bronchioles at the site where they join the alveolar sacs. Pacific Northwest Laboratories, Richland, Wash. Brazell, R.S., J.H. Unlike white allotrope, it is nontoxic. The ignition fuse was from the standard-issue late-war egg hand grenade. The authors stated that the gross pathology and histopathological evaluations of the rats, guinea pigs, and dogs failed to show any lesions that could be attributed to the smoke inhalation. Some of the animals were held for 24 months in clean air after the exposure. Burrows. The TLV-TWA that has been set for phosphoric acid provides an acceptable concentration to which nearly all workers might be repeatedly exposed, day after day, without adverse effects during their working lifetime.
