4.2 Explanatory notes

  4.2.1 The hazard profiles indicated in columns A, B, C and E are taken from the evaluations carried out by GESAMP.

  • Column A - Bioaccumulation
  • Column B - Damage to living resources
  • Column C - Hazard to human health (oral intake)
  • Column E - Reduction of amenities.

  4.2.2 The column D rating by GESAMP has been dispensed with for this categorization as that rating relates to hazard to human health (skin contact and inhalation), which has no direct bearing on aquatic pollution.

  4.2.3 To establish whether a substance is a Category A, B, C or D pollutant it is necessary to relate the GESAMP hazard profile with the table shown above.

  4.2.4 For a substance to qualify in any category it is necessary to satisfy all the requirements in any one row at one and the same time.

  4.2.5 To establish the individual substance categorization, the table should be read horizontally so that, for example, a rating T in column A and a 3 in column B results in categorization A; whereas a single rating of T or 3 results in categorization B.
