STODDARD SOLVENT<br />

The fourth case was an individual who had used a Stoddard-type<br />

solvent in a large open tub, once a year for 20 years, usually indoors.<br />

A slight reduction in all formed blood elements was seen. Ihe patient<br />

survived after a splenectomy was performed. The authors concluded that<br />

these cases implicated Stoddard-type solvents as possible myelotoxic<br />

agents but since no information was given on solvent composition, it is<br />

not possible to rule out other myelotoxic compounds such as benzene<br />

(2332).<br />

Dermal exposure to, undiluted Stoddard solvent for 10 weeks resulted<br />

tests<br />

in follicular dermatitis<br />

revealed latent jaundice<br />

<strong>and</strong> jaundice.<br />

<strong>and</strong> possibly<br />

One year after exposure,<br />

permanent liver damage<br />

(2333).<br />

67.3.3 Levels of Concern<br />

OSHA (298) currently permits exposure to 500 ppm as an 8-hour<br />

time-weighted-average. The ACGIH (3,) has set a time-weighted-average<br />

of 100 ppm, with a short-term exposure limit of 200 ppm.<br />

67.3.4 Hazard Assessment<br />

No carcinogenicity tests have been conducted for Stoddard solvent.<br />

Mutagenicity data are negative for bacteria <strong>and</strong> mammalian cells in<br />

culture; negative results were also obtained in a rat dominant lethal<br />

study <strong>and</strong> mouse micronucleus test (1914,1968).<br />

.<br />

Exposure of pregnant rats to vapor levels of 300 ppm, 6 hours<br />

daily during gestation was without effect (1969).<br />

Animal studies indicate mild narcotic effects <strong>and</strong> irritation of<br />

mucous membranes with acute exposure (46). Long-term exposures result<br />

in kidney damage (2309), particularly in male rats. The incidence <strong>and</strong><br />

severity of renal toxicity appeared to increase with concentration <strong>and</strong><br />

exposure duration (1974,2309,1970).<br />

In humans, acute exposure produce eye, nose <strong>and</strong> throat irritation,<br />

nausea, vomiting, diarrhea <strong>and</strong> fatigue (38.1975). High vapor<br />

concentrations can produce headaches <strong>and</strong> narcotic effects (38).<br />

Prolonged industrial exposures to very high concentrations of Stoddard<br />

solvent have been linked to fatigue <strong>and</strong> bone marrow hypoplasia<br />

(38,1967); it is unclear, however, if other myelotoxic solvents were<br />

also involved.<br />

67.4 SAMPLING AND ANALYSIS CONSIDEWUIIONS<br />

Determination of the presence of Stoddard solvent in soil <strong>and</strong><br />

water requires collection of a representative field sample <strong>and</strong> laboratory<br />

analysis for the specific major components attributed to Stoddard<br />

solvent; however, the relative concentrations of the constituents, <strong>and</strong><br />

even the constituents themselves, will vary with time <strong>and</strong> distance from<br />
