The ready biodegradability of heptan-1-ol was evaluated in a study (Gancet, 2011) performed in accordance with OECD testing guideline 301 F and GLP requirements. The maximum level of biodegradation was 84 % in 28 days. Therefore, according to these results, heptanol is considered as readily biodegradable.

Moreover, it was demonstrated that heptanol degrades fast in aerobic biodegradation screening tests. Other tests show 30% of theoretical BOD was expended in 5 days and 28.9% of theoretical BOD was expended in 1 day using 500 ppm of heptan-1-ol and an activated sludge inoculum (Dore et al., 1975).

During another study (Gerhold & Malaney, 1966) it was shown that at the end of 24h, the oxydation of heptan-1 -ol was equivalent to 28.9 % of the Theoretical Oxygen Demand.

Based on these results, it can be considered that heptan1-1-ol is readily biodegradable. Besides, it is characterized by a low potential of adsorption. So, no simulation tests in water, sediment and soil compartments are proposed.
