Antarctic Copepod Metal Toxicity Bioassays from 2012-2013 Season

Two 14-day bioassays testing the toxicity of cadmium, copper, and zinc, both individually and in mixtures, to Antarctic marine copepods. The experiments were conducted during the 2012-2013 season at Davis Station, East Antarctica, with mortality counts and measured metal concentrations recorded. Data are provided in Excel workbooks containing point estimates like LC10 and LC50 values calculated at 4, 7, 10, and 14 days of exposure.

Use Cases

• Modeling concentration-response relationships for single metals based on measured LC10 and LC50 values.
• Analyzing synergistic or antagonistic effects of metal mixtures on copepod mortality.
• Calibrating toxicity models using the measured metal concentrations from water samples taken at four time points.
• Studying the impact of environmental conditions (0°C, 16:8 light:dark photoperiod) on toxicity outcomes.

Strengths

• Experiments used measured metal concentrations from ICP-OES analysis, not just nominal concentrations.
• Each treatment included four replicates and each test included eight controls.
• Point estimates (LC10, LC50) were calculated at four different exposure durations (4, 7, 10, 14 days).

Limitations
