Definition of 1,5,9-Cyclododecatriene (CDDT):
1,5,9-Cyclododecatriene is a liquid with a yellow tint and pungent odor. [1]
This is the common definition for 1,5,9-Cyclododecatriene (CDDT), other definitions can be discussed in the article

CDDT is used to produce cyclododecane, which is used in the production of dodecanedioic acid.
It has a high volatibility, therefore half of the concentration in a river can be evaporated in less than 1,3 hours. In the atmosphere it will be degraded rapidly (less than 30 minutes). As a consequence CDDT will be found mostly in soils, and very little in water, air or sediment. It however is considered not to be biodegradable. It has a low tendency towards bioaccumulation. Concentrations above 0,2 mg/l cause acute toxicity to fish, algae and invertebrates. Doses of 2,5 g/kg body weight were lethal to rats.
Considering CDDT it is only used as an intermidiate in the production of other chemicals, its high votality and degrability, it has only a minor potential aquatic exposure and thus also only a minor risk to aquatic organisms.[1]
