Administration / exposure
- Route of administration:
- inhalation
- Type of inhalation exposure:
- not specified
- Vehicle:
- other: Aerosol
- Details on inhalation exposure:
- vehicle Aerosol derived by passing air over PNA dissolved in isopropanol and warmed.

Doses / concentrations
- Remarks:
- Doses / Concentrations:
0, 10, 32, 80 mg/m3 (analytical)
Basis:
analytical conc.
- No. of animals per sex per dose:
- total no. of animals: 40
- Control animals:
- yes
- Details on study design:
- sub-acute exposure period: 6 hours per day, 5 days per weekcontrol group: yes, concurrent vehicle Aerosol derived by passing air over PNA
dissolved in isopropanol and warmed. Groups of 10 rats/sex/group were housed in stainless steel and glass chamber and exposed under whole
body conditions to one of three levels of test material. A vehicle control group was exposed to isopropanol in a similar fashion and treated similarly for evaluation. Chamber atmospheres and particle size were analytically determined. Dosing occurred 6h/d, 5d/wk for 4 consecutive weeks; animals
were observed daily for clinical signs, weighed weekly, food and water given ad libitum , serum chemistry (BUN, SGPT, SAP, GLU, ALB, T.Protein, Glob.,
Na, K, P, Ca, Cl) and hematology (Hgb, HCT, RBC, Methem., clot time,T/Differ. Leuko, red cell morph) parameters collected on day 0 and 28.
Ophthalmoscopic exams conducted on day 0 and 28. Organ weights (gonads, hrt, kid, lvr, lu, pit, spln, brain) recorded at termination; all animals
necropsied at term; microscopic evaluation of approx. 40 tissues and organs (including gonads) for all high dose and control rats; spleens examined for all lower dose animals. Statistical methods used included: Bartletts test
Results and discussion
Effect levels
- Dose descriptor:
- NOAEC
- Effect level:
- 10 mg/m³ air
- Based on:
- test mat.
- Sex:
- male/female
- Basis for effect level:
- other: non-significant elevation in blood methemoglobin,significant increases in mean spleen weight (both sexes), iron deposition and extramedullary hematopoiesis seen in spleens (both sexes)
Target system / organ toxicity
- Critical effects observed:
- not specified
Applicant's summary and conclusion
- Conclusions:
- The NOAEC (no observed adversed effect concentration) value observed was 10 mg/m³ air in rat by inhalation exposure in a subacute study conducted with 4-nitroaniline which shows non-significant elevation in blood methemoglobin.
- Executive summary:
The NOAEC (no observed adversed effect concentration) value observed was 10 mg/m³ air in rat by inhalation exposure in a subacute study conducted with 4-nitroaniline which shows non-significant elevation in blood methemoglobin.
