There are no data on the toxicity of alcohols to terrestrial plants. The significance of this lack of data may need to be considered , since Level III results indicate that if released to air, or directly to soil, e.g. via spreading of WWTP sludge, a significant proportion of longer chain alcohols would be expected to arise in the terrestrial compartment. However, the absolute quantity is expected to be small, and rapid degradation is anticipated, particularly in view of the rapid degradation seen in studies using soils.
