A variety of treating agents, equipment and methods are available for use as countermeasures against marine pollution from oil spillage. The organizations or individuals responsible for preparing or implementing response plans--sometimes in a crisis environment--must choose among these. When such a choice is among specific treating agents, the decision should be based on the agent effectiveness and probable environmental effects for the situation at hand. In particular, information on dosage rates, application methods, stability, reaction times, toxicity to humans, and toxicity to indigenous marine life is needed for objective decisions. The present dearth of information does not provide such a decision making basis. The existence of laboratory test procedures which objectively measure either the effectiveness or toxicity effects in terms relatable to a specific application environment or for comparison of different agents is doubtful. Contributing factors and circumstances include:

Many treatment agent manufacturers and organizations using them have their own methods of evaluation.

The pressure of commercial competition has encouraged the marketing of new products without adequate evaluation.

The technology and development of treating agents is at a comparatively immature state of advancement.

Public pressures have tended to encourage intensified development activities and application in a crisis environment.

The objective of the work reported herein was to assess existing effectiveness and toxicity measurement methods. It was to be determined whether one existing test or a combination of existing tests is suitable for the effectiveness evaluation of the range of treating agents available and is relevant to the conditions under which the agents would be used. It was also to be determined whether any combination of existing bioassay techniques will adequately measure the toxicity of treating agents. A range of petroleum products was to be considered, as well as a range of environmental conditions. In the case that no identifiable set of testing methods is totally adequate, the problem areas were to be defined and test development recommended.
