In a 28 day reproduction test on Collembola
(Folsomia candida), Sodium Pyrithione 40% caused no
statistically signficiant effects on mortality up to and including to
the concentration of 500 mg/kg soil dry weight. The NOEC for mortality
was determined to be 500 mg/kg soil dry weight. The LC50 was
determined to be 822 mg/kg soil dry weight. The reproduction values
were not statistically differnet compared to the control at 250 mg/kg
soil dry weight, which was therefore determined to be the NOEC for
reproduction and to be the overall NOEC. The EC50 for reproduction was
determined to be 670 mg/kg soil dry weight. The information
