Table 1 Summary of criteria for the categorization of plant protection products as PBT or vPvBT from [10]
Criteria | POP | PBT |
|---|---|---|
Persistence (P) | ||
Persistent | Water, DT50 > 2 months | Marine water, t½ > 60 days |
Sediment, DT50 > 6 months | Fresh water, t½ > 40 days | |
Soil, DT50 > 6 months | Marine sediment, t½ >180 days | |
Soil, t½ > 120 days | ||
Very persistent | - | Water, t½ > 60 days |
Sediment, t½ > 180 days | ||
Soil, t½ > 180 days | ||
Bioaccumulation (B) | ||
Bioaccumulative | BCF > 5,000 or log KOW > 5 | BCF > 2,000 in aquatic species |
Other, e.g., very toxic or bioaccumulation in nontarget species | ||
Very bioaccumulative | - | BCF > 5,000 |
Toxicity (T) | No specific criteria other than “significant adverse effects” | Chronic NOEC <0.01 mg/L or is a carcinogen, mutagen, or toxic for reproduction, or other evidence of toxicity |
Potential for long-range transport (LRT) | Air, DT50 > 2 d or modeling or monitoring data which shows long-range transport | None |
