The study was a 96 -hour static exposure with the rainbow trout, Oncorhynchus mykiss and the resulting 72 and 96 -hour LC50 value was 28.6 mg DIBC/L. There was also a 48 -hr Daphnia magna study that followed OECD and USEPA guidelines. This study was considered reliable with a Klimisch rating of 2 and the 48 -hr EC50 value was reported as 47.8 mg/L. In addition, a 96 -hr algal study with Selenastrum capricornutum (now known as Pseudokirchneriella subcapitata) was also available.
