Results and discussion

Any other information on results incl. tables

Enzymatic and cytological profiles of lung lavage fluids were examined. At the higher exposure concentration, a slight increase in lysosomal enzymes was found 1 day after exposure, and a slight increase in acid phosphatase was found throughout the study (i.e. for 21 days). Histopathological examination at day 1 after exposure showed focal accumulations of macrophages, and the alveolar capillaries were diffusely congested. The authors considered these responses to be minimal.

Applicant's summary and conclusion

Conclusions:
Chromium chloride can cause minimal irritation to hamster's respiratory.
Executive summary:

The respiratory irritancy of chromium chloride was studied by exposing Syrian hamsters to nebulized liquid aerosols of chromium(III) chloride at 2.8 or 77 mg/m3 for 0.5 h.
