1988b). Gratt. Decreased activity of 5'-nucleotidase and alkaline phosphatase in macrophages has been associated with enhanced in vitro antitumor and antiviral activity (Lundy and Eaton 1994). Weimer et al. Of the animals exposed at 1,200 mg/m3, 10.8% died spontaneously or were necropsied in a moribund state. 76, self-igniting phosphorus. Punainen fosfori, kosteus ja nopeutettuna lämmöllä, vapauttaa fosforihydridia. Softair Granaten günstig online kaufen in Shop von Sniper Airsoft Supply große Auswahl an Softair Granaten Softair Grenade Softair Zubehör günstig No treatment-related histopathological changes were found outside the respiratory tract (Aranyi 1983, 1984; Lundy and Eaton 1994). Hän sai fosforikranaatin selkään. In this video we chat about war crimes, light some fires and look at a wholesome side of white phosphorus, all while trying not to be poisoned. 76 special incendiary grenade also commonly known as the A.W. Therefore, the subcommittee recommends 40, 10, and 2 mg/m3 for 15 min, 1 hr, and 6 hr, respectively, for the EEGLs based on the animal data. It causes skin to melt away from the bone and can break down a victim's jawbone, but white phosphorus - known in Vietnam as Willie Pete - is still used by sections of the world's military. The Acute and Chronic Effects of Repeated Exposure to United Kingdom Red Phosphorus Screening Smokes in Rats, Mice, Guinea Pigs, and Rabbits. The authors concluded that the pathological changes identified could not be attributed to exposure to the smoke. 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. These data suggest that a change in alveolar macrophage populations might be induced by exposure to RP-BR that activated these cells (Aranyi et al. The grenades unearthed by the SPEN team were commonly known as the 'SIP' - self-igniting phosphorus - grenade and were primarily to be used as an anti-tank weapon. Ballou (1981) found that gross pathology in rats following exposure to high concentrations of airborne RP-BR smoke varied somewhat with concentration, but the pathology consistently involved the laryngeal and proximal tracheal regions. Because the guinea pig might be uniquely sensitive to respiratory irritants, results from this species were not used. min/m3, respectively. Other approaches include WP soaked felt pads (which also burn more slowly, and pose a reduced risk of incendiarism) and PWP, or plasticised white phosphorus. The fact that micronuclei are not observed after a 4-week exposure or a 2-week recovery period does not diminish the significance of observations at the end of the 2-week exposure period. Red phosphorus is used in matches and flares. No evidence of latent toxic effect or exposure-related tumor formation was found that could be agent-related. Seven of those had significant laryngeal and tracheal lesions that consisted of a fine fibrinlike coat on the laryngeal and proximal tracheal mucosa. The M34 White Phosphorus Smoke Grenade or "Whiskey Pete" was a smoke / incendiary grenade manufactured by Rocky Mountain Arsenal from the late 1950s and used by U.S. forces during the Vietnam War and was also used during the First Gulf War.The M34 WP Grenade replaced the World War II M15 WP grenade. Red phosphorus is also used by the military for smoke munitions. Merken. Weimer et al. 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. The California Environmental Protection Agency indicates, however, that the substance is still toxic and should be handled carefully. American Conference of Governmental Industrial Hygienists, Cincinnati, Ohio. After 2 weeks of exposure, 50% of male rats exposed at 750 mg/m3 had minimal fibrosis, and all the test animals exposed at 1,200 mg/m3 had minimal-to-mild fibrosis. ACGIH (1991) recommended the TLV-TWA for phosphoric acid by analogy to comparable experience and data for sulfuric acid. At all these concentrations, the animals showed marked laryngeal and epiglottal erosion, hemorrhage, ulceration with fibrin deposition, enlarged lymph nodes, edema with pulmonary congestion, and mucus accumulation in the trachea. Abbreviations: hr, hour(s); min, minute(s); d, day(s); wk, week(s); ♂, male; ♀, female. (1980) stated that these changes could not be attributed to the test substance. 8833719 M3A1 igniter) Pulmonary Effects. Weimer et al. The maximum anticipated total dose for field exposures (i.e., the peak concentration of a single volley of L8A1 grenades) has been estimated to be about 500 mg/m3, and such a cloud would be expected to persist for 1 to 3 min (Weimer et al. Cederwall, and L.B. Holmberg. Those effects persisted for up to 2 days after exposure. White phosphorus is believed to have been first used by Fenian arsonists in the 19th century in the form of a solution in carbon disulfide. These studies indicate that RP-BR smoke is only slightly toxic to the rat and dog, but that the guinea pig is more sensitive. Jump up to the previous page or down to the next one.
