FUEL OILS 66-30<br />

Methemoglobinemia (a loss of the oxygen carrying capacity of the<br />

blood), is the main toxic effect of nitrite <strong>and</strong> nitrate ingestion.<br />

Early symptoms include headache, fatigue, nausea, vomiting, chest<br />

pain <strong>and</strong> cyanosis. With increasing methemoglobin concentrations, there<br />

may be weakness, dizziness, incoordination, joint pain <strong>and</strong> muscular<br />

tremors (200,480).<br />

Various N-nitroso derivatives have caused malignant tumors in<br />

various organ systems in laboratory animals. Generally, as the<br />

molecule increases in size, carcinogenic activity decreases (12).<br />

Exposure to these compounds should be avoided. Specific information on<br />

2 nitroso compounds - N-nitrosodimethylamine <strong>and</strong> N-nitrosodiphenylamine<br />

- may be found in Volume 1 of the Guide.<br />

66.3.5 Levels of Concern<br />

There are no criteria or st<strong>and</strong>ards for fuel oils. OSHA (298) has<br />

set a time-weighted-average exposure limit for kerosene at 500 ppm.<br />

66.3.6 Hazard Assessment<br />

Fuel oils themselves do not appear to be carcinogens but they do<br />

contain several polycyclic aromatic hydrocarbons which are'carcinogens<br />

<strong>and</strong>/or cocarcinogens (2219). A fuel oil blend was highly active in<br />

both cellular assays <strong>and</strong> skin painting studies (1819). Positive<br />

mutagenic findings were observed in an Ames test, a mouse lymphoma<br />

assay <strong>and</strong> a rat bone marrow study for fuel oil number 2 (1914). Diesel<br />

fuel gave negative results in both .the Ames <strong>and</strong> mouse lymphoma assay<br />

but positive results in the rat bone marrow assay (1914).<br />

A reproductive study with rats exposed by inhalation at levels up<br />

to 408 ppm suggested no adverse effects (1915).<br />

Acute toxic effects of ingested fuel oils included alopecia,<br />

dermal irritation <strong>and</strong> open sores in the genital area of exposed rats.<br />

The oral ID,, values ranged from 5 to 17.5 g/kg for rats (1924).<br />

Dermal studies in rabbits indicated severe dermal irritation,<br />

weight loss, anorexia, ataxia <strong>and</strong> lethargy following a dose of 5 g/kg<br />

(1924). Fuel oils are also minimally to moderately irritating to<br />

rabbit eyes (1924). No chronic animal data were found.<br />

'In humans, GNS depression is the chief systemic reaction to fuel<br />

oils (17). Ingestion of less than rt ounce has been fatal (17). Permal<br />

<strong>and</strong> inhalation exposures to diesel fuel have induced nephropathy in<br />

humans (1814,1815,1816).<br />
