The acute toxicity of PEMP product to green alga was determined in accordance with OECD TG No 201 and GLP. A 2.8% inhibition at the limit concentration tested (loading rate of 100 mg/L, analytically verified to correspond with 0.88 mg/L) was deemed biologically irrelevant. The 72h-ErC50 and ErC10 were determined to be >0.88 mg/L; the NOErC 0.88 mg/L. The study was concluded to be reliable with restrictions.
A study was performed to assess the effect
of the test material on the growth of the green alga Pseudokirchneriella
subcapitata.The method followed the OECD TG No 201 and GLP. Pseudokirchneriella
subcapitatawas exposed to a loading rate of 100 mg/L (six
replicate flasks) and a control (six replicate flasks) for 72 hours,
under constant illumination and shaking at a temperature between 22 and
Analyses showed that the initially measured
concentration of 0.88 mg/L of the 100 mg/L loading rate was stable
during the 72 -hour test period.
Statistically significant inhibition of
growth rate was found at the limit concentration, however the 2.8%
inhibition was deemed biologically irrelevant. The 72h-ErC50 and ErC10
were determined to be >0.88 mg/L; the NOErC 0.88 mg/L.
The study was conducted without deviations
that influence the quality of the results. However, since the analytical
method used did not meet all validation criteria, the resulting measured
concentrations of the test item in the test medium can only be taken as
indicative. The study is concluded to be reliable with restrictions as
the order of magnitude of the measured concentrations is considered to
