In order to test acute toxicity to
invertibrates Daphnia were exposed to a limit effective loading of
nominally of 100 mg/L PDI dissolved in dilution water. The substance has
not a definite or unique structure and consists of several components. A
Water Accommodated Fractions (WAF) was used to test effects at an
effective loading and no specific analysis was performed. 50 mL of the
solution were taken and diluted with 0.5 mL of dilution water containing
5 daphnids resulting in a final concentration of 100 mg/L. For each test
item concentration and the control 4 replicates were prepared. The
content of PDI during the exposure period was verified by DOC
determination. The test was conducted as a static test with the test
medium unchanged throughout the duration of the test. The criterion of
adverse effects used in this study was the item-induced alteration of
the normal mobility behaviour and the loss of locomotory actions of the
neonates, observed at 24 and 48 hours.
No toxic effects against
daphnia magna were observed at the limit loading of 100 mg/L under
This toxicity study is classified
as acceptable and satisfies the guideline requirements for the actue
After 48 hours no toxic effects against daphnia magna were observed at the limit loading of 100 mg/L under exposure conditions (Spoo-Klöppel, 2016).
