The results from the screening toxicity tests Artemia salina , Microtox®, and Mitochondria RET test were compared with those obtained from OSPAR (Oslo and Paris Commissions)‐authorized procedures for testing of offshore chemicals ( Skeletonema costatum, Acartia tonsa, Abra alba , and Corophium volutator ). In this study 82 test substances (26 non‐water soluble) were included. The Microtox test was found to be the most sensitive of the three screening tests. Microtox and Mitochondria RET test results showed good correlation with results from Acartia and Skeletonema testing, and it was concluded that the Microtox test was a suitable screening test as a base for assessment of further testing, especially regarding water‐soluble chemicals. Sensitivity of Artemia salina to the tested chemicals was too low for it to be an appropriate bioassay organism for screening testing. A very good correlation was found between the results obtained with the Skeletonema and Acartia tests. The results indicated no need for more than one of the Skeletonema or Acartia tests if the Skeletonema median effective concentration or Acartia median lethal concentration was greater than 200 mg/L. The sediment‐reworker tests ( A. alba or C. volutator ) for chemicals that are likely to end up in the sediments (non‐water soluble or surfactants) should be performed, independent of results from screening tests and other OSPAR species.
