Administrative data
PBT assessment: overall result
- Name:
- Chlorphenesin
- Type of composition:
- legal entity composition of the substance
- State / form:
- solid: particulate/powder
- Related composition:
- Chlorphenesin
- Reference substance:
- Chlorphenesin
- Name:
- Chlorphenesin
- Type of composition:
- boundary composition of the substance
- State / form:
- solid: particulate/powder
- Reference substance:
- Chlorphenesin
- PBT status:
- the substance is not PBT / vPvB
- Justification:
According to Annex XIII of the REACH Regulation (EC n. 1907/2006), a substance is PBT if it fulfils all three of the following criteria.
1) Persistence
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.
2) Bioaccumulation
A substance fulfills the bioaccumulation criterion (B) when:
– the bioconcentration factor (BCF) is higher than 2000.
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.
3) Toxicity
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.
The substance fails to fulfil the bioaccumulation criterion. Based on a partition coefficient of log Pow = 1.23 at 23 °C, a potential for bioaccumulation may be excluded. Indeed, threshold value of potential for bioconcentration is log Pow = 4 as indicated in the CLP Regulation (EC n. 1272/2008). Therefore, the substance is not PBT.
According to Annex XIII of the REACH Regulation (EC n. 1907/2006), a substance is vPvB if it fulfils the following criteria.
1)Persistence
A substance fulfils the very persistence criterion (vP) when:
- the half-life in marine, fresh- or estuarine water is higher than 60 days, or
- the half-life in marine, fresh or estuarine water sediment is higher than 180 days, or
- the half-life in soil is higher than 180.
2)Bioaccumulation
A substance fulfils the very persistence criterion (vP) when:
- the bioconcentration factor is greater than 5000.
Based on a partition coefficient of log Pow = 1.23 at 23 °C, a potential for bioaccumulation may be excluded. Therefore, the substance is not vPvB.
