Guidelines for the categorization of noxious liquid substances
The Revised GESAMP hazard evaluation procedure
A Bioaccumulation and Biodegradation | B Aquatic Toxicity
Numerical rating | A1 Bioaccumulation | A2 Biodegradation | B1 Acute toxicity LC/EC/IC50 (mg/L) | B2 Chronic toxicity EC10 or NOEC (mg/L)
A1a: log Pow | A1b: BCF
0 | log <1, log > ca.7 MW > 1000 | no measurable BCF | R: readily biodegradable | AT >1000 | CT >1
1 | 1≤ log <2 | 1≤ BCF <10 | NR: not readily biodegradable | 100˂ AT ≤1000 | 0.1˂ CT ≤1
2 | 2≤ log <3 | 10≤ BCF <100 | 10˂ AT ≤100 | 0.01˂ CT ≤0.1
3 | 3≤ log <4 | 100≤ BCF <500 | 1˂ AT ≤10 | 0.001 ˂ CT ≤0.01
4 | 4≤ log <5 | 500≤ BCF <4000 | 0.1˂ AT ≤1 | CT ≤0.001
5 | 5≤ log < ca.7 | BCF ≥4000 | 0.01˂ AT ≤0.1
6 | | AT ≤0.01
C Acute Mammalian Toxicity
Numerical rating | C1 Oral toxicity | C2 Dermal toxicity | C3 Inhalation toxicity
LD50/ATE (mg/kg) | LD50/ATE (mg/kg) | C3a | C3b
vapour/mist LC50/ATE (mg/L) | mist only LC50/ATE (mg/L) | vapour only LC50/ATE (mg/L)
0 | ATE >2000 | ATE >2000 | ATE >20 | ATE >5 | ATE >20
1 | 300˂ ATE ≤2000 | 1000˂ ATE ≤2000 | 10˂ ATE ≤20 | 1˂ ATE ≤5 | 10˂ ATE ≤20
2 | 50˂ ATE ≤300 | 200˂ ATE ≤1000 | 2˂ ATE ≤10 | 0.5˂ ATE ≤1 | 2˂ ATE ≤10
3 | 5˂ ATE ≤50 | 50˂ ATE ≤200 | 0.5˂ ATE ≤2 | 0.05˂ ATE ≤0.5 | 0.5˂ ATE ≤2
4 | ATE ≤5 | ATE ≤50 | ATE ≤0.5 | ATE ≤0.05 | ATE ≤0.5
D Irritation, Corrosion and Long-term Health Effects
Numerical rating | D1 Skin irritation and corrosion | D2 Eye irritation and corrosion | D3 Long-term health effects
0 | not irritating | not irritating | C – Carcinogenic
1 | mildly irritating | mildly irritating | M – Mutagenic
2 | irritating | irritating | R – Reprotoxic
3 | severely irritating or corrosive | severely irritating | Ss – Sensitizing to skin
3A Corr. (≤4 h) | | Sr – Sensitizing to respiratory system
3B Corr. (≤1 h) | | A – Aspiration hazard
3C Corr. (≤3 min) | | T – Target Organ Toxicity
N – Neurotoxic
I – Immunotoxic
E Interference with Other Uses of the Sea
Numerical Rating | E1 Flammability flashpoint (oC) | E2 Physical effects on wildlife and benthic habitats | E3 Interference with coastal amenities
– | Fp - Persistent floater F - Floater S - Sinker G - Gas E - Evaporator D - Dissolver and combinations thereof
0 | (not flammable, | no interference
does not burn) | no warning
1 | Fp >93 | slightly objectionable
warning, no closure of amenity
2 | 60˂ Fp ≤93 | moderately objectionable
possible closure of amenity
3 | 23≤ Fp ≤60 | highly objectionable
closure of amenity
4 | Fp <23
