Paris Commission sediment reworker ring-test 1993. Technical report
report
This report summarises the test results obtained from the 1993 Paris Commission
(PARCOM) sediment reworker ring test. The main features of the test methods with the bivalve Abra alba, the polychaete Arenicola marina, the amphipod Corophium volutator and the sea urchin Echinocardium cordatum, as well as the biology and availability of the test animals are summarised briefly. The sediment spiking technique employed and the recommended parameters for choosing a suitable base sediment are presented. The test results are shown in tabular form, along with data on control mortality and a comparison with the 1991 ring-test. An overview of the effort required to carry out the individual tests prepared by TNO and WQI, Denmark is also given. The ring test produced sufficient valid results for a thorough evaluation of each species on scientific and technical grounds. It was observed during range finding tests by the expert laboratories that one of the test substance, Petrofree, was only toxic at far higher concentrations than usually demanded by most regulatory authorities and it was withdrawn from the Arenicola marina, Corophium volutator and Echinocardium cordatum tests. Arenicola marina failed to achieve an LC50 result in 5 tests for the PAH fluoranthene and on the basis of this insensitivity is considered as a less suitable general test method than the other three.
