Marine pollution Classification (MARPOL Annex II)
Category Description
Z Noxious Liquid Substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a minor hazard to either marine resources or human health and therefore justify less stringent restrictions on the quality and quantity of the discharge into the marine environment.

Alternate names for this chemical
1,4-Butanediol
Butane-1,4-Diol
1,4-Butylene Glycol
Tetramethylene Glycol
1,4-Dihydroxybutane

  About the project

HNS-MS is a decision-support tool that Belgian and French maritime authorities as well as coastguard stations can activate in order to forecast the drift, fate and behavior of acute marine pollution by Harmful Noxious Substances (HNS) accidentally released in the marine system.
