001929 - No. 1 Diesel Fuel ?
Date of Issue: 20- Mar -2007
Page 5/8
Status: Final
Hydrodesulfurized Kerosene ..C946
Carcinogenicity: Petroleum middle distillates have been shown to cause skin tumors in mice following repeated and prolonged
skin contact. Follow -up studies have shown that these tumors are produced through a non- genotoxic mechanism associated
with frequent cell damage and repair, and that they are not likely to cause tumors in the absence of prolonged skin irritation.
Animal studies have also shown that washing the skin with soap and water can reduce the tumor response. Middle distillates
with low polynuclear aromatic hydrocarbon content have not been identified as a carcinogen by NTP, IARC or OSHA. Diesel
exhaust has been identified as a probable cancer hazard by IARC
Reproductive: Skin application in female rats at 494, 330, or 165 mg /kg daily for 7 consecutive weeks (premating, mating, and
gestation), or for 8 consecutive weeks in males did not result in systemic, reproductive, or developmental toxicity.

Naphthalene
Carcinogenicity: Naphthalene has been evaluated in two year inhalation studies in both rats and mice. The National
Toxicology Program (NTP) concluded that there is clear evidence of carcinogenicity in male and female rats based on increased
incidences of respiratory epithelial adenomas and olfactory epithelial neuroblastomas of the nose. NTP found some evidence of
carcinogenicity in female mice (alveolar adenomas) and no evidence of carcinogenicity in male mice. Naphthalene has been
identified as a carcinogen by IARC and NTP.

When No 1 distillates (kerosene, jet fuels, heating oils) escape into the environment due to leaks or spills, most of their constituent
hydrocarbons will evaporate and be photodegraded by reaction with hydroxyl radicals in the atmosphere. The half -lives in air for many
of the individual hydrocarbons is less than one day. Less volatile hydrocarbons can persist in the aqueous environment for longer
periods. They remain floating on the surface of the water; those that reach soil or sediment biodegrade relatively slowly. Soil
contaminated with jet fuel can develop adapted microbial species able to use the fuel as a carbon source; soil aeration and nutrient
supplementation can enhance this biodegradation.
Reported LC501EC50 values for water- soluble fractions of kerosenes and jet fuels are usually in the range of 10 to 100 mg/liter.
Adverse effects on the gills, pseudobranch, kidney and nasal mucosa have been reported in fish involved in spills of jet fuel. Juvenile
clams may be particularly sensitive to marine sediments contaminated as a result of spilled jet fuel. Direct toxicity and fouling of sea
birds from jet fuel can occur if birds dive through floating layers of spilled fuel.
Phytotoxic effects of jet fuel have been reported following exposure of plants to sprays or vapors. Lack of seed germination and
inhibition of seedling growth may also occur. There is evidence for moderate bioaccumulation of the water - soluble hydrocarbons
present in jet fuels.
