Description of key information

Additional information

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.
