Both the ready biodegradability test as well
as the BOD5/COD ratio indicate that the test substance is not readily
the nature of their design and use, textile dyes are not intended to be
readily biodegradable as this would assist in the rapid destruction of
the dyestuff, rendering it unfit for purpose. There are ISO, European,
American (AATCC) and national standards for the colour fastness of dyes.
Dyes are required to have specific fastness properties. If the dyes were
biodegradable, it would not be possible for them to have these fastness
properties. As such, it is accepted that such substances are not readily
biodegradable under relevant environmental conditions. A published study
(Pagga & Brown, 1986) describes the results of the testing of 87
dyestuffs in short-term aerobic biodegradation tests. The authors of
this publication concluded that dyestuffs are very unlikely to show any
significant biodegradation in such tests and that 'there seems little
point in carrying out such test procedures’ on dyestuffs.
