Description of key information

Additional information

Not all of the data for TDCPP that have been included in the summary table can be considered acceptable for determining PNEC values. Only the most reliable and relevant data point for each of the relevant taxonomic groups (algae, invertebrates, fish) has been used for the purposes of determining a PNEC in the aquatic freshwater environment

Acute toxicity:

  1. 96h-LC50 to fish: 1.1 mg/L
  2. 48h-EC50 to invertebrates: 3.8 mg/L
  3. 72h-ErC50 to algae: 4.6 mg/L

Chronic toxicity:

6m-NOEC to fish (endpoint: weight) : 2 µg/L

21d-NOEC to invertebrates (endpoint: reproduction): 0.5 mg/L

72h-ErC10 to algae: 2.3 mg/L (NOEC: ≥ 1.2 mg/l)

Toxicity to WWTP micro-organisms:

EC50 = >10000 mg/L
