ENVIRONMENTAL FATE AND BEHAVIOUR |
|
|
Artificial pollution sources |
Release to the environment of this substance can occur from industrial use: as an intermediate step in further manufacturing of another substance (use of intermediates), in the production of articles, in processing aids at industrial sites, as processing aid, of substances in closed systems with minimal release and formulation of mixtures. Other release to the environment of this substance is likely to occur from: indoor use (e.g. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners).
