Additional information
The toxicityl of 4 -Methoxybenzaldehyd to algae was investigated in two studies: one non-GLP study according to the german national standard guideline DIN 38412, Part 9 (BASF 1989) and one GLP study according to OECD 201 (SIDS 2009). The measured effect concentration of the most sensitive study according to OECD TG 201 revealed an EC50 value of 61 mg/l and an NOEC of 0.65 mg/L according to the growth rate of the algae.
