OECD SIDS o-<strong>TOLUIDINE</strong><br />

5. TOXICITY ID: <strong>95</strong>-<strong>53</strong>-4<br />

DATE: 07.01.2005<br />

Method-Evaluation, no data on cytotoxicity, unclear use: o-toluidine or otoluidine<br />

hydrochloride<br />

15.07.2004 (152) (233) (234)<br />

Type : Gene mutation in Saccharomyces cerevisiae<br />

System of testing : Strain C658-K42<br />

Test concentration : 0, 0.5, 1.0, 3.0 mg/ml<br />

Cycotoxic concentr. : +S9: >3.0 mg/ml; -S9: >0.5 mg/ml<br />

Metabolic activation : with and without<br />

Result : positive<br />

Method : other<br />

Year : 1989<br />

GLP : no data<br />

Test substance : other TS: o-toluidine, no data on purity<br />

Result : positive with S9-mix at 3.0 mg/ml<br />

Reliability : (4) not assignable<br />

Insufficient documentation<br />

15.07.2004 (235)<br />

Type : Gene mutation in Saccharomyces cerevisiae<br />

System of testing : RS112<br />

Test concentration : 0, 100, 1000, 2000, 3000, 5000 µg/ml<br />

Cycotoxic concentr. : >=3000 µg/ml<br />

Metabolic activation : with and without<br />

Result : positive<br />

Method : other: DEL recombination assay<br />

Year : 1994<br />

GLP : no data<br />

Test substance : other TS: o-toluidine, no data on purity<br />

Result : o-toluidine increased the frequency of DEL recombination 2.6-fold in the<br />

absence of S9 and more than 5-fold in the presence of S9. In the absence<br />

of S9 an increase of DEL recombination frequency was first seen at a<br />

concentration of 3 mg/ml whereas in the presence of S9 an increase<br />

appears already at 1 mg/ml. The frequency if ICR was not increased<br />

according the definition.<br />

Reliability : (2) valid with restrictions<br />

Method Evaluation<br />

15.07.2004 (236) (237)<br />

Type : Gene mutation in Saccharomyces cerevisiae<br />

System of testing : strain JD1<br />

Test concentration : no data, lowest effective concentration: 50 µg/ml<br />

Cycotoxic concentr. : >50 µg/ml<br />

Metabolic activation : with and without<br />

Result : positive<br />

Method : other: Detection of Mitotic Gene Convertants in the yeast S. cerevisiae<br />

strain JD1<br />

Year : 1981<br />

GLP : no data<br />

Test substance : other TS: see freetext TC<br />

Result : Mitotic gene conversion without S9 mix. Lowest effective concentration was<br />

50 µg/ml.<br />
