Abstract:

The toxicity of phenanthrene to mysid shrimp and 5 deep-sea crustacean species from the Gulf of Mexico was assessed using a 48-hour constant exposure equipped with a passive dosing system. Mortality was assessed at specific intervals, and concentrations of the toxicant were measured at the start and end of the exposure to facilitate calculation of an LC50 for use in the target lipid model.

Purpose:

The purpose of this experiment was to establish reliable measurements of mortality in order to generate LC50 values as inputs to the target lipid model.

Data Parameters and Units:

Target= nominal target concentrations in µg/L Chamber= the chamber number N= number of organisms in the chamber T0h, T24h, T48h: sample times; 0, 24, and 48 hours of exposure Values listed below sample times are measured concentrations and are reported in µg/L Time from exposure initiation (h)= number of individuals dead (cumulative count) Geo Mean= the geometric mean concentration of phenanthrene in each chamber across all time points in µg/L Temperature in deg C Salinity in psu
