The blend of kerosene used for jet fuel consists of 20% aromatic hydrocarbons ranging from C9-C16. Current literature studies on JP-8 and other jet fuels are limited for the assessment of reproductive and developmental toxicity risk to humans. The flammable nature of an accelerant is what presents the most significant challenge to crime scene investigators and laboratory scientists. Todd, in Reference Module in Earth Systems and Environmental Sciences, 2013. Classification of petroleum distillates. However, one study with JP-8 given undiluted by gavage to rats for 90 days at several doses (0.750, 1500, and 3000 mg/kg) reported an increase in relative testicular weights, without any observable histopathological changes (Mattie et al., 1991). One study did not find significant differences in sperm parameters in the USAF personnel exposed to JP-4/JP-8 and other hydrocarbons compared to unexposed controls (Lemasters et al., 1999). The existing evidence, however, is inconclusive about whether kerosene heater use is a cause of respiratory and asthma symptoms in developed countries.96,105,117-119 In developing countries where kerosene may also be used for lighting using inefficient wick lamps, this fuel has been associated with increased risk of respiratory infections, especially tuberculosis.120,121, Suryanarayana V. Vulimiri, ... Brinda Mahadevan, in Reproductive and Developmental Toxicology (Second Edition), 2017. Petroleum distillates are colorless liquid petrochemical mixtures with kerosene-like odor and a boiling range of 90–240 °C containing hydrocarbons ranging between C7 and C12 divided into three major components. The hazards of aspiring hydrocarbons during ingestion depend on viscosity and surface tension, both of which are related to the molecular weight. Photodegeneration is rapid in the air phase. Why is the number of protons and electrons equal in an atom? Synonyms: Jet fuel 5, Jet fuel 8, K-1 kerosene, hydrotreated distillate light, white kerosene, stove oil, light distillate, furnace oil, fuel oil light. As it is not as flammable as the lower fractions, it is still used around the world for lighting and heating. How many electrons would it take to equal the mass of a helium nucleus? This is because kerosene is not a pure chemical compound. Any lack of thoughtfulness or competency on the part of the chemist can potentially result in an innocent person being charged with arson. Kerosene does not have a chemical formula. See all questions in Basic Atomic Structure. The kerosene and paraffin difference is that the paraffin is a component of kerosene, and when petroleum refining is complete, it remains as a waxy residue. The key to securing arson evidence is to do so quickly and contain it within special air-tight canisters. A fourth type (type 4) might be considered as a crude mixture not treated beyond the process of distillation. High inhalation exposure to kerosene can induce CNS depression, characterized by ataxia, hypoactivity, and prostration.
