Any other information on results incl. tables
An exposition up to 877 mg/m³ 1,8-naphtylenediamine (highest technical feasible concentration) was tolerated without mortality. All animals exposed to 413 and 877 mg/m³ and revealed at the first exposition day a reduced motility and a bloody nose, additional one rat exposed to 413 mg/m³ a reduced respiration rate. All rats had no clinical symptoms at the first post-observation day. At the 3rd post-observation day in all rats exposed to 413 mg/m³ and in female rats exposed to 877 mg/m³ a reduction of weight gain was observed.
Applicant's summary and conclusion
- Executive summary:
Four groups of 5 male and 5 female Wistar rats were nose/head-only exposed to an aerosol concentration of 1,8-naphthylendiamine at an analytical concentration of 0, 156, 413 or 877 mg/m³ (highest technical feasible concentration) for 4 hours. The animals were
observed for mortality, weight and clinical signs through day 14. A gross necropsy was performed.An exposition up to 877 mg/m³ 1,8-naphtylenediamine (highest technical feasible concentration) was tolerated without mortality. All animals exposed to 413 and 877 mg/m³ and revealed at the first exposition day a reduced motility and a bloody nose, additional one rat exposed to 413 mg/m³ a reduced respiration rate. All rats had no clinical symptoms at the first post-observation day. At the 3rd post-observation day in all rats exposed to 413 mg/m³ and in female rats exposed to 877 mg/m³ a reduction of weight gain was observed. Therefore the LC50 is > 877 mg/kg bw for male and female rats
