were (Elbe in Dresden, Germany = 1):
- Bilina, tributary of the Elbe in the Czech Republic: 4-6
- Elbe in the Czech Republic: 2-3
- Elbe in Dresden, Germany: 1
The authors assumed that the irregular occurence and concentration
pattern of these amines indicated a significant input of untreated
wastewater from batch production in chemical factories in the Czech
Republic. Several samples taken from river sites in Saxony demonstrated
that no significant input of aromatic amines occured in Germany.
Reliability : (2) valid with restrictions
Basic data given
Flag : Critical study for SIDS endpoint

Type of measurement : concentration at contaminated site
Media : surface water
Concentration :
Method : Solid Phase Extraction, followed by HPLC
Remark : Boernick et al. (2001) refer to Boernick (1998)
Result : In 1994-1996, o-toluidine was monitored in the Elbe and some of its
tributaries in Germany and the Czech Republic (Boernick, 1998). With a
detection limit of 28 ng/l, o-toluidine was detected in the following waters:
· Bilina river, vicinity of the confluent with the river Elbe in Usti (Aussig,
Czech Republic), but downstream of the wastewater outlet of an azo dye
producer, in 1 out of 7 samples: >21,200 ng/l (value out of the calibration
range). o-Toluidine was not detected upstream of this outlet
· Elbe in Czech Republic, 2 sampling sites downstream confluent with
Bilina, in 2 out of 6 samples: 30 and 1,130 ng/l, respectively. o-Toluidine
was not detected upstream of the confluent of Elbe and Bilina
· Elbe, Pillnitz (Saxony, Germany), km 43 from Czech border, in 1 out of 13
samples: 122 ng/l
· Elbe, Dresden (Saxony, Germany), km 55 from Czech border, in 3 out of
56 samples: 93, 110, and 1,010 ng/l
· Other sites in Saxony (Germany), in 3 out of 45 samples: 70, 72, and 191
ng/l.

Type of measurement : concentration at contaminated site

Method : Solid Phase Extraction, followed by GC/MS
Remark : The limit of detection obtained with external calibration is given as 8.6 ng/l
and the limit of determination as 25.4 ng/l (Eppinger 2000).
Result : Between March 1997 and March 1998, 52 random samples were taken
from the river Elbe at Pillnitz (Saxony, Germany; 43 km from Czech
border). o-Toluidine occured in 6 % (3) of the samples with a maximum of
0.04 µg/l and an average of 0.03 µg/l for these 3 samples. Other result
(Eppinger 2000) were:
· Elbe at Kötitz (Saxony, Germany; 73 km from Czech border). o-Toluidine
occurred in 2 of 12 samples (0.064 µg/l and 0.039 µg/l)
· Elbe at Scharfenberg (Saxony, Germany; 76.5 km left side from Czech
border). o-Toluidine occurred in 2 of 13 samples (0.059 µg/l and 0.03 µg/l)
· Elbe at Meißen (Saxony, Germany; 76.5 km right side from Czech
border). o-Toluidine was not detected in 12 samples (LOD: 0.025 µg/l)
· Elbe at Torgau (Saxony, Germany; 153 km from Czech border). o-
Toluidine occurred in 1 of 3 samples (0.03 µg/l)
