A static test with zebrafish (OECD 203) indicated no mortality at 1000
mg/L after 96 hour.
Two short-term aquatic toxicity studies are available for fish for
polymeric MDI (CAS 9016-87-9). In a study with Oryzias latipes
(Nakata, 1982), no acute toxicity was observed after 96h exposure to
3000 mg/L (semi-static). The Nichi-Nou-Sei B2735 (1965) protocol was
followed, which is similar to OECD 203. A static test with Danio rerio
(OECD 203) gave no mortality at 1000 mg/L, which was the highest
concentration tested (Caspers et al., 1986). This value may be
considered for the derivation of a PNECaqua. A third fish
study with Danio rerio is available (Rhone-Poulenc, 1977), but
lacks some critical information. Hence it is classified as unreliable.
The 24h-EC50 was determined to be > 500 mg/L. Based on the justification
in the category approach of methylenediphenyl diisocyanates (MDI), it is
assumed that all MDI analogues included in the category have a similar
