Color chemistry and the environment.
Dyes, and by extension the various organic compounds used for coloration, including organic pigments and fluorescent whitening agents (FWAs), are among the organic chemicals which we encounter as technological and functional necessities in nearly every sphere of our daily lives. They also greatly influence our mood and thus contribute enormously to the very quality of the lives we lead. At the same time we have come to realize that our achievements and continuing technological progress are only worthwhile provided they pose no hazard to the environment. Tremendous efforts have been undertaken on a worldwide scale to identify, measure, evaluate, and eliminate the undesirable effects of chemicals and, hence, dyes on man and the environment. The present paper deals in particular with the environmental problems associated with the manufacture and use of dyes, problems so complex and so varied in impact that only a discerning appraisal can put them into proper perspective. An attempt is made to define and evaluate these problems and to show, with reference to selected examples, what measures have been and are being implemented to overcome them. Various aspects of the relevant legal regulations, the obligation on manufacturers to take due care in their operations, and product liability are touched upon. This much is certain: A good deal of creative, interdisciplinary effort and meticulous attention to minor detail will be necessary to master existing and future environmental problems in this area. That is the challenge facing all scientists engaged in color chemistry.
