[X11. PBT-SUBSTANCES U.K.
A substance that fulfils all three of the criteria of the sections below is a PBT substance.
1.1. Persistence U.K.
A substance fulfils the persistence criterion (P-) when:
the half-life in marine water is higher than 60 days, or
the half-life in fresh- or estuarine water is higher than 40 days, or
the half-life in marine sediment is higher than 180 days, or
the half-life in fresh- or estuarine water sediment is higher than 120 days, or
the half-life in soil is higher than 120 days.
The assessment of the persistency in the environment shall be based on available half-life data collected under the adequate conditions, which shall be described by the registrant.
1.2. Bioaccumulation U.K.
A substance fulfils the bioaccumulation criterion (B-) when:
the bioconcentration factor (BCF) is higher than 2 000 .
The assessment of bioaccumulation shall be based on measured data on bioconcentration in aquatic species. Data from freshwater as well as marine water species can be used.
1.3. Toxicity U.K.
A substance fulfils the toxicity criterion (T-) when:
the long-term no-observed effect concentration (Noec) for marine or freshwater organisms is less than 0,01 mg/l, or
the substance is classified as carcinogenic (category 1 or 2), mutagenic (category 1 or 2), or toxic for reproduction (category 1, 2, or 3), or
there is other evidence of chronic toxicity, as identified by the classifications: T, R48, or Xn, R48 according to Directive 67/548/EEC.]
