OECD SIDS o-<strong>TOLUIDINE</strong><br />
3. ENVIRONMENTAL FATE AND PATHWAYS ID: <strong>95</strong>-<strong>53</strong>-4<br />
DATE: 07.01.2005<br />
Deg. product :<br />
Method : other: Calculation method<br />
Year : 1996<br />
GLP :<br />
Test substance : other TS: o-toluidine<br />
Method : Biodegradadtion rates in soil, expressed as half-lives, are correlated with<br />
molecular groups using a neural network. A back-propagation neural<br />
network with 14 input nodes, 12 nodes in the hidden layer and 2 output<br />
nodes, is used to correlate the input data with the log values of the high<br />
and low soil half-lives for each chemical in database. The range of halflives<br />
for organic contaminants in soil was estimated.<br />
Result : A high soil half-live for o-toluidine was estimated to be 18.1 d. 3.5 d was<br />
estimated for the low soil half-live.<br />
Reliability : (4) not assignable<br />
Not commonly used calculation method<br />
18.06.2004 (88)<br />
Type : aerobic<br />
Inoculum : other: Mixture of sludge from different sources, non-adapted<br />
Contact time :<br />
Degradation : 5 (±) % after 28 day(s)<br />
Result :<br />
Deg. product :<br />
Method : OECD Guide-line 301 C "Ready Biodegradability: Modified MITI Test (I)"<br />
Year : 2000<br />
GLP : no data<br />
Test substance : other TS: o-Toludine, purity not specified<br />
Result : 5 % degradation related to BOD<br />
1 % degradation related to TOC<br />
0 % degradation determined with HPLC<br />
Test condition : - Initial concentration of inocolum: 30 mg/l<br />
- Initial concentration of test substance: 100 mg/l<br />
- Different analysis methods used: BOD, TOC and HPLC<br />
Reliability : (2) valid with restrictions<br />
Basic data given<br />

3.6 BOD5, COD OR BOD5/COD RATIO<br />
3.7 BIOACCUMULATION<br />
Species : other: Crassostrea gigas (Pacific oyster)<br />
Exposure period : 24 hour(s) at 15 °C<br />
Concentration : 5 mg/l<br />
Elimination :<br />
Method : other<br />
Year : 1985<br />
GLP : no data<br />
Test substance : other TS: o-Toluidine, ring-labeled [14C], specific activity: 18.2 mCi/mM<br />
(radiopurity > 99 %, tested by HPLC)<br />
Method : - Oysters were obtained from a clean body of water (Johnson Oyster Co.,<br />
Drakes Bay, California).<br />
- Single mussels were exposed in 3 replicates.<br />
- o-Toluidine loss was observed.<br />
- BCF was determined at equilibrium.<br />
