| Abstract |
Tanker accidents at sea have led to the examination of the toxic effects on organisms of 14 oil-emulsifying agents both in fresh- and sea-water. The lethal limits of the substances examined were between 0.001 and 0.1 ml/l. For an appraisal of these values it is important to know that some substances cause different reactions in fresh-water and sea-water. Crude oil mixtures (Irak-Crude-Oil) have similar lethal limits. A layer of crude oil alone on the surface of the water is less detrimental than a mixture of crude oil and emulsifying agents. On the part of the fisheries considerable objections should be raised against the use of such agents. In cases of soilage of beaches, harbours, and industrial plants, it must be decided whether damages to the local flora and fauna can be accepted or not. |
