DRAFT- NOT FINAL (Jan, 2010)
| | Very High (vH) | High (H) | Moderate (M) | Low (L) Very Low (vL) |
Acute Aquatic Toxicity 96 hr LC50 (fish) 48 hr EC50 (crustacea) 72 or 96 hr ErC50 (algae, aquatic plants) | GHS Cat 1 (≤ 1 mg/L) Specified Lists | GHS Cat 2 (>1 to 10 mg/L) Specified Lists | GHS Cat 3 (>10 to 100 mg/L) Specified Lists | Not classifiable as GHS Cat 1, 2, or 3 (> 100 mg/L) |
| Chronic Aquatic Toxicity NOEC or EcX | ≤ 0.1 mg/L | > 0.1 to 1.0 mg/L | >1.0 to 10 mg/L; or GHS Cat 4 | > 10 mg/L |
| Persistence | 1/2 Life (soil, sediment) > 180 days; or 1/2 Life (water) > 60 days; or 1/2 Life (air) > 5 days | 1/2 Life (soil, sediment) >60 to 180 days; or 1/2 Life (water) >40 to 60 days; or 1/2 Life (air) > 2 to 5 days; or potential for long-range environmental transport | 1/2 Life (soil, sediment) >16 to 60 days; or 1/2 Life (water) >16 to 40 days; or 1/2 Life (air) < 2 days | Low: Meets GHS Definition for Rapid Degradability Very Low: Meets 10-day window as measured in a ready biodegradaton test without degradationproducts of concern |
| Bioaccumulation Potential | BCF/BAF > 5000; or Log Kow > 5 | BCF/BAF >1000 to 5000; or Log Kow > 4.5 to 5 Weight of evidence for presence in humans and wildlife | BCF/BAF > 500 to 1000; or Log Kow >4 to 4.5 Suggestive evidence of presence in humans and wildlife | Low:BCF/BAF > 100 to 500; or Log Kow<4 Very Low: BCF/BAF ≤ 100 |
