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.

PNECaqua (freshwater)

Given the reactivity of TDI with water it is probably more suitable to use data obtained from only acute toxicity studies to derive a PNECaqua value.

For Klimisch 2 studies only, the following test results were used for the PNECaqua value.

Fish (Tadokoro et al, 1997): 96h LC50 133mg/l

Daphnia (Tadokoro et al, 1997): 48h EC50 12.5mg/L

Algae (Tadokoro et al, 1997): 96h EC50 3230mg/l

A PNECaqua (freshwater) of 0.0125 mg/l may be derived using the EC50 of 12.5mg/l, obtained with the most sensitive species, and an assessment factor of 1000.

PNECaqua (marine water)

As daphnia are the most sensitive species the EC50 of 12.5 mg/l may be used to derive the PNECaqua (marine water).
