Abstract:

Method for measuring the acute toxicity of effluents and receiving waters to freshwater and marine organisms. This dataset reports the survival/mortality rate of Daphnia sp. exposed to various concentrations of cactus mucilage and COREXIT 9500.

Purpose:

To determine the lethal concentration of cactus mucilage on daphnia.

Data Parameters and Units:

Concentrations of mucilage/dispersants are reported in mg/L, survival of Daphnia (%), mortality rate (%) Gelling extract (GE), Non-gelling extract (NE), exposure time (hours), # of living daphnia (count)

Methods:

Measuring LETHAL CONCENTRATION 50 (LC50): Concentration of a substance causing mortality in 50% of test organisms for a specified time interval. Standard measure of surrounding medium toxicity.
