- Executive summary:
In an acute oral toxicity study, five groups of ten rats (5 males and 5 females) were given a single dose of the appropriate amount of diesel fuel (marketplace sample) (2.5, 5.0, 10, 15, or 20 mL/kg) via oral gavage. Dose levels were chosen to produce expected mortality rates between 10 and 90%. Signs of mortality and toxicity were observed daily for the duration of the study (14 days). Body weight was measured on days 0 and 7, and upon death. Gross necropsy was performed on each animal when they died or by day 14.
Mortality rates of the five dose groups (2.5, 5, 10, 15, 20 mL/kg) were 12.5, 20, 70, 40, and 90% respectively. Signs of toxicity were observed in all dose groups. Severity increased with increased dose. Clinical signs observed were oily urine stains and oily diarrhoea, which resulted in hair loss, irritation, redness, and sores. In many cases, the anal area had open sores. In the highest dose (20 mL/kg) the entire ventral side and legs were affected. In some instances there was blood around the eyes, nose, and mouth. Other symptoms noted included lethargy, pus, or blood at the urinary orifice. Gross pathology observations were also similar in each dose group. In rats who survived for the duration of the study (14 days), there were few abnormalities. In these rats minor observations included enlarged Peyer's patches on intestines. Both animals that died and survived exhibited mild irritation and congestion in the lungs, in addition to fluid-filled abscesses in the lungs. The majority of the animals that died before day 14 showed intestinal damage including, hemorrhaging, thinning of intestinal walls, and increased gas in the gastrointestinal tract.
Under the conditions of this study, the test material had an oral LD50 of 9.0 mL/kg (approx 7600 mg/kg) and a 95% confidence interval of 5.58 and 14.51 mL/kg. the test material was determined to have a median lethal dose according to the study report. The test material is not classified according to EU criteria.
This study received a Klimisch score of 1and is classified as reliable without restriction because it was conducted similar to guideline study OECD 401.

Additional information
Acute toxicity data are available for oral, dermal and inhalation routes. The L50 / LC50 values were as follows:
Oral - 7600 mg/kg
Dermal - > 4300 mg/kg
Inhalation - 4100 mg/m3
Justification for classification or non-classification
The data available do not meet the classification criteria for acute oral and dermal toxicity.
Data on acute inhalation indicate that that material warrants classification as Category 4 inhalation.
