Question 2572 Deck General

The correct answer is A) Octanol. Octanol is considered a noxious liquid substance for regulatory purposes, such as under the International Convention for the Prevention of Pollution from Ships (MARPOL) and the US Coast Guard regulations. Noxious liquid substances are those that, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a hazard to either marine resources or human health. Octanol falls under this classification due to its potential environmental and health impacts. The other options are incorrect because: B) Acetonitrile is not a noxious liquid substance, C) Hog grease is a type of animal fat, not a regulated chemical, and D) Cetyl-Eicosyl methacrylate is a synthetic polymer, not a noxious liquid substance.
