Highly objectionable because of persistency,
smell or poisonous or irritant characteristics; as a result contaminated

substance is a human carcinogen or that the substance has the potential to
produce other serious specific long-term adverse health effects in
humans.

Moderately objectionable because of the above
characteristics, but short term effects leading only to temporary
interference with use of beaches; also used when there is credible
scientific evidence that the substance is an animal carcinogen but where
there is no clear evidence to indicate that the material has caused cancer
in humans, or when there is evidence from laboratory studies that the
substance could have the potential to produce other serious specific
long-term adverse health effects.

The descriptive terms such as highly toxic,
non-hazardous, etc., were use d by the original panel for the
purposes of the 1973 International Conference on Marine Pollution. They have
no particular significance in terms of hazard posed outside the particular
circumstances addressed by that Conference and IMO sub-committees, i.e.
marine pollution as a consequence of discharges or spillages from ships.
