Description of key information

NOEC (28 d) for Chironimus sp. = 1.85 mg a.i./L (measured initial, OECD 219)

Key value for chemical safety assessment

Additional information

A test, investigating effects of OPP (CAS-No. 90-43-7) on larvae of sediment dwelling organisms (Chironimus sp.) according to OECD Guideline 219 is available. For the sediment dwelling organism Chironomus sp. a NOEC value of 1.85 mg a.i./L was observed (Egeler & Gilberg, 2005).
