acute toxicity results show that Daphnia is the most sensitive species
with a 48-hr EC50 (immobilisation) of 1.7 mg/l.
on this value, alpha-terpinene does not meet the criteria for Aquatic
acute daphnia EC50 (immobilisation) of 1.7 mg/L for alpha-terpinene
alongside the fact that it is not rapidly biodegradable and the log Kow
is > 4, mean that a classification as Aquatic Chronic 2 is warranted. An
M-Factor is not required for this substance as the acute toxicity EC50
is >/= 1.0 mg/L.
