Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The 7 d LC50 values on survival or inhibition of fertilization for Pleuronectes americanus, Mulinia lateralis, Paleomonetes vulgaris, Americamysis bahia, Leptocheirus plumulosos, Menidia beryllina, Homarus americanus, Cyprinodon variegatus and Dyspanopius sayii were determined to be 0.017, 0.0379, 0.0594, 0.0606, 0.0616, 0.070, 0.071, 0.142 and 0.195 mg NP/L.
Additional information
The acute toxicity of NP (90% para-C9 phenol) was determined for various saltwater invertebrates and fish in 7 day flow-through experiments with various concentrations of test substance. Organisms were exposed simultaneously in duplicate flowthrough exposure chambers. Doses were verified analytically. The surviving organisms were counted at 2, 4, 8, 12, and 24 h and daily through Day 7. To obtain data for lower-temperature species, static tests were conducted and monitored daily. Under the study conditions, the 96 h LC50 values for survival or inhibition of fertilization for Pleuronectes americanus, Mulinia lateralis (48 h LC50), Paleomonetes vulgaris, Americamysis bahia, Leptocheirus plumulosos, Menidia beryllina, Homarus americanus, Cyprinodon variegatus and Dyspanopius sayii were determined to be 0.017, 0.0379, 0.0594, 0.0606, 0.0616, 0.070, 0.071, 0.142 and 0.195 mg/L (Lussier SM, 2000).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
