The objective of the Oslo and Paris Commission’s (OSPAR) work connected to offshore exploration and production (E&P) chemicals, is to reduce the use and discharge of the chemicals posing an unacceptable risk to the marine environment. Within OSPAR the required test procedure for offshore E&P chemicals have, to a large extent, been harmonized. The standard methods used are generally based on well established OECD Guidelines or proposed guidelines and require that that the tests are conducted according to OECD’s GLP (Good Laboratory Practice) principles. The basic data set includes the following ecotoxicological tests (OSPAR, 1995):
  • Toxicity

  • Algae: Skeletonema costatum

  • Herbivore: Acartia tonsa

  • Sediment reworker: Corophium volutator

  • Fish: Scopthalmus maximus

  • Biodegradation

  • A 28-day seawater test

  • Bioaccumulation

  • n-octanol/water partition coefficient, Pow
