Abstract:

The dataset includes data from acute toxicity tests for Daphnia magna, following EPA guidelines (EPA/600/8 - 87/011). D. magna were tested for 48 hours in the lab, using different concentrations of heavy metals, along with the Deep Water Simulator to add hydrostatic pressure to test if there was a difference in mortality when pressure was increased. The heavy metals tested were: copper (CuSO4), cadmium (CdCl2), Zinc (ZnSO4), and Nickel (NiCl2).

Purpose:

The purpose of this dataset is to show the survival difference in acute toxicity tests of four heavy metal toxins at 1ATM and 100ATM and using this information to show that an increase in hydrostatic pressure has an effect on survival for acute toxicity tests.

Data Parameters and Units:

Time (Hours), Concentrations (PPB), Pressure (PSI / ATM / KPa), Number of individuals alive, Temperature (Celsius), Date (MM/DD/YYYY)
