Applicant's summary and conclusion

Executive summary:

A semi static dose range-finding study conducted in Orange-red killifish (Oryzias latipes) for the fish bioconcentration study provided a 48 hr LC50 of > 500 ppm (w/v). A dispersant was used. This study was conducted according to Japanese MITI guidelines and Good Laboratory Practices guidelines.
