Risk-Oriented Approach to Assessment of Hexamethylenediamine Pollution of Aquatic Ecosystems

HMD is widely used by industry in the manufacture of polyamide materials, as well as a substance in the production of epoxy resins and other substances. At the same time, HMD is a physiologically active, toxic and dangerous substance (hazard class II), which can cause burns, eczema-like dermatitis, diseases of the nervous system and gastrointestinal tract in humans. Wastewater contaminated with HMD, which is discharged into natural reservoirs, causes the death of aquatic organisms and aquatic vegetation, degrades the quality of water, which becomes unusable. HMDA is listed as a hazardous substance by the European Chemicals Agency and the American Conference of Government Hygienists of Industry.
