AQUATIC TOXICITY TESTING OF OIL PRODUCTS - SOME RECOMMENDATIONS

Developments in environmental legislation are creating a demand for data which can be used to classify oil products on the basis of the potential hazard they present to the aquatic environment. Current test method guidelines for determining the toxicity of substances to aquatic organisms are not generally applicable to oil products. Data which can be used for classifying oil products will, we believe, follow from preparing specific test media and from modifying testing procedures. A new concept termed 'loading rates' will also provide a basis for comparing data from tests with poorly soluble and readily soluble products.
