The exposure of chemical substances to human beings through any kind of contact with water is used to dominate the discussion of the environmental problems of chemical substances in water. Recently, the effects of chemical substances on the ecosystem through water have also become a subject of discussion. This review describes the methods for biodegradation tests, aquatic toxicity tests, and simulation tests which are the main principles of environmental compatibility evaluation in water, and in addition demonstrates the most recent examples of evaluation for surfactants using these methods.<BR>These new examples of evaluation are distinguished by the fact that the possibilities of ulti mate biodegradation of surfactants are vigorously investigated and the aquatic toxicities of surfactants, including their intermediates, are evaluated thoroughly. On the development of surfactants which might in future be disposed of or released into the environment, it seems that each company is responsible for ascertaining their environmental compatibility before putting them on the market, and at the same time, the strategically important point for companies is to be able to conduct the most effective evaluation in the shortest time.
