Test substance : other TS: o-Toluidine, purity is not specified
Method : A river die-away test was developed by using an inoculum from river water
at different sampling sites.
River water samples were collected from an unpolluted (Takayama of the
Minoh river) and a polluted site (Kitahshi of the Neya river) in Osaka, Japan
and used as microorganism source. A filter method was used for the
preparation of inoculum.
o-Toluidine was added to 60 ml test tubes as sole carbon source at a
concentration of 20 mg/l. 25 ml of the inoculum (artificial river water +
microorganism source + chemical) were incubated at 25 °C with shaking in
the dark for 14 days. A blank containing microorganisms without test
chemical and a control carrying only the test chemical were included. TOC
was measured periodically.
Result : Microorganisms trapped from Takayama (unpolluted) were able to degrade
less than 20 %. Microorganisms trapped from Kitahashi (polluted) started
degrading o-toluidine from the 2nd day and reached a maximum by the 8th
day. After 15 days more than 90 % of o-toluidine was degraded (result
taken from a graph).
Reliability : (2) valid with restrictions
