Study design

Details on sampling:

Sediment samples were collected from 13 sites in the Hamilton Harbour area located between 43°15'58" latitude and 79°46'51" longitude for Station 1 and 43°17'38" latitude and 79°48'28" longitude for Station 13. Sediments were collected with a box-corer to provide sufficient samples for analyses. Each sample was stored in solvent rinsed glass jars at 4°C in a dark place until analysis. Stations were selected to represent the diverse depositional environments of the Hamilton Harbour. These include sediments influenced by shipping and dredging activities as well as sites that reflect deposition of coal storage and coking operations in two adjacent foundries.

Details on results:

See table 1
Recoveries of quinoline spiked blank sediments (n=5):
at 150 µg/kg: 99.0 +/- 4.5 (66%)
at 15 µg/kg: 10.7 +/- 13.7 (71%)

The recoveries of deuterated quinoline added as internal standard for the extraction procedure in the sediments samples from the different locations were between 50 and 93%.

Applicant's summary and conclusion

Conclusions:

Concentrations in the sediments of Hamilton harbour were between 8 and 63 µg/kg dw.

Executive summary:

An integrated analytical methodology has been developed for determining nitrogen-containing polycyclic aromatic hydrocarbons including quinoline, which enables quantitation of individual contaminants as low as 1 µg/kg in sediment samples. A cross-sectional profile from the Hamilton Harbour sediment samples was analyzed for azaarenes. These contaminants were separated by Soxhlet extraction, and pH adjustment allowed their isolation from different classes of neutral and acidic components. Separation and identification of the organic bases in each sample were achieved by using open tubular column gas chromatography with thermionic detection and HRGC-mass spectrometry.

Quinoline concentrations were between 8 and 63 µg/kg dw.
