Abstract: 
With the rise in attention called to ecological and environmental conservation, studies have been conducted especially in regards to the adverse effects of dumped chemical waste from industrial plants that have made their way to marine ecosystems. Such research is expensive and time-consuming, requiring numerous resources that are not always available, and so instead, Dr. K. R. Hoover developed the aquatic toxicity equations, able to identify the median mortality lethal concentration (LC 50), which is the predicted concentration required to halve the existing (fish) population within a certain time frame. The concentrations predicted in this experiment applied to six species of fish: the fathead minnow, the guppy, the bluegill, the goldfish, the golden orfe, and the melaka high-eyes. The Abraham general solvation model is a mathematical equation that can be used to calculate the numerical values of specific solute descriptors; in this case, the values for 4-methyl-3-nitrobenzoic acid were determined, and ultimately substituted into the aquatic toxicity equations, which were derived themselves from the Abraham model. From the toxicity equations, the median mortality lethal concentrations of 4-methyl-3-nitrobenzoic acid were collected for the six species of fish, and it was concluded that the golden orfe would suffer the most in an environment with 4-methyl-3-nitrobenzoic acid as a pollutant.
