THE POTENTIAL FOR FUEL AND LUBRICANT MATErials to cause harmful effects in the environment needs to be evaluated. A reliable approach to evaluate the inherent hazard of a material to the environment is by testing the individual chemical properties in the environmental compartments of concern in separate, carefully controlled laboratory test systems: • The media exchange rates of a material may be deduced from measurements of key physical properties. • The degradation rates under specific conditions may be determined in tests for biodegradability, hydrolysis, photolysis, and photooxidation. • The toxicity to or accumulation by organisms may be determined in single species tests using organisms of known number, age, health, and under constant environmental conditions. • The specific test method to be used, the test organisms, and the data quality management of the testing are defined by the use of the data. In general, these test data are developed for submissions related to the registration of products to satisfy regulatory requirements, that allow the discharge of municipal and industrial wastes, or environmental (or ecological) risk assessment in response to perceived environmental contamination. This discussion provides a general overview of this testing and does not address specific requirements for individual test methods.
