PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

Heptanoic acid is readily biodegradable: 94.5% and 98.7 % biodegradation (DOC removal) after 4 and 11 days, respectively. The 10-days window was met (OECD TG 301 A; EU Method C.4-A).

Based on its log Kow value (2.54) Heptanoic acid has a low potential for bioaccumulation.

Heptanoic acid does not fulfil the Toxic criterion: concerning the aquatic compartment EC50 > 0.1 mg/L, NOEC > 0.01 mg/L and NOEC for mammals > 30 mg/kg food. Last but not least, Heptanoic acid is not classified as carcinogenic, mutagenic or toxic for reproduction.

Consequently, Heptanoic acid is not PBT nor vPvB.
