This makes them attractive for roc The engine of these tanks can use a lot of different fuels, and are usually fuelled with jet fuel because it's readily available. In the present study the results of a neurological and neurophysiological health examination of 29 aircraft factory workers chronically exposed to jet fuel vapors are presented. In one epidemiological investigation, 30 workers exposed to jet fuel at a Swedish jet-motor factory for an average of 17 years were studied for possible adverse health effects. It was quickly discerned that as a hydrocarbon fuel, such as Jet Fuel is cooled, one (1) part per million of water This chapter summarizes the findings on potential neurotoxicity from exposure to jet-propulsion fuel 8 (JP-8) presented in the National Research Council report Permissible Exposure Levels for Selected Military Fuel Vapors (NRC 1996) and reviews additional studies, most of which were completed after the 1996 report was published.

Methods In the context of a case-control study conducted in Montreal, Canada, 1,924 histologically-confirmed prostate Aviation fuels are complex combinations of petroleum hydrocarbons that fall under two major categories: aviation turbine fuel (CAS RN 64741-86-2) and aviation gasoline fuels (CAS RNs 64741-87-3 and 68527-27-5). The targeted compounds were selected on the basis of their mutagenicity and/or carcinogenic potential, the identification of compounds from related studies, Additionally, the percent' composition of the major organic species measured in each jet fuel are presented together with standard fuel analysis and GC/FID chromatograms. While road transport fuels sold in Europe only contain a maximum of 10 sulphur parts per million (ppm), jet fuel typically contains from 10 to 1,000 ppm, with typical averages ranging between 300 and 600 ppm (Zschocke et al. Drug Chem. � Fuel oils come from crude petroleum and are refined to meet specifications for each use. JP-5 and JP-8 is shorthand for jet propellants 5 and 8. The navy uses JP-5 as the fuel for aircraft on carriers. 1-D . 2001). The performance-enhancing additives found Read chapter 4 Effects of Jet-Propulsion Fuel 8 on the Respiratory Tract: This report provides a critical review of toxicologic, epidemiologic, 12 Carcinogenic Effects of Jet-Propulsion Fuel 8 141–161; Appendix A Permissible Exposure Three-hundred Fischer 344 rats and 300 C57BL/6 mice of each sex were divided into three treatment groups and exposed intermittently (6 hr/day, 5 days/week) to JP-4 jet fuel vapors at concentrations of 0, 1000, and 5000 mg/m3 for 12 months. CRC Press, Boca Raton, pp 21–26. JP-7 has not been found at any sites. Other pertinent literature is also presented, but is described in less detail than the Fuel oils are liquid mixtures produced from petroleum, and their use mostly involves burning them as fuels. For more information, call the ATSDR Information Center at 1-800-232-4636. Major toxic effects reported for JP-4 This book provides a critical review of toxicologic, epidemiologic, and other relevant data on jet-propulsion fuel 8, a type of fuel in wide use by the U. 3 Jet Fuel (Kerosene) Jet fuel is the third most important transportation fuel. Air Force has recently started JP-5 applied to the skin for 2 years was not carcinogenic in mice. They emphasize the need to develop surrogates that describe both the important physical and Petroleum middle distillate (PMD) fuels are mixtures of hydrocarbons that distill between approximately 170-370 degrees C. Carcinogenic Effect of Military Fuel Vapors 11. atsdr. Jet A is the type of fuel used in civilian aircraft; however, the U. They give off more air pollution than contained burning, has classified some of the chemical substances found in burn pit emissions as “known to be carcinogenic to humans. The heavily exposed group (group A) had exposure described as “continuous exposure for several hours daily to high concentrations of jet fuel fumes in the fuel rig or the test cells or intermittent exposure to high Jet fuel spills can also result in exposure via contaminated groundwater or soil. The components . The 1-in-4 lifetime cancer risk from breathing the emissions from the Chevron jet fuel is higher even than the lifetime Nor can states monitor for the carcinogenic new fuels without knowing IARC: DIESEL ENGINE EXHAUST CARCINOGENIC Lyon, France, June 12, 2012 ‐‐ After a week-long meeting of international experts, exhaust emissions and to continue to work with the engine and fuel manufacturers towards those goals. Since that time, a large number of cohort and case–control studies have been published on the topic, many of which provided high-quality data on exposure and potential confounding factors. (JP-8, domestic; F-34 international) and the commercial jet industry equivalents Jet A (domestic) and Jet A-1 (international flights) are consumed internationally on an annual basis (26 billion gallons in the US) [Armbrust Aviation Group, 1998; Henz, 1998]. JP-5 (jet fuel) fuel oil no. JP-8 has been found to have low acute toxicity with the adverse effects being slight dermal irritatio A broad range of waste was burned and included computers, animal carcasses, medical waste, lithium ion batteries, plastic waste, Styrofoam, insecticide canisters, DEET-soaked items, human excrement, food waste, and vehicles []. cdc. JP-5 and JP-8 are used as military aircraft fuels. Effects of Military Fuel Vapors on the Central Nervous System 8.
