Over the last decade, the oil sector in coastal regions has been increasing its operations in an accelerating speed, in platforms as well as in the navigation area, with transportation involving oil, and it is fair to say that there is an increase in the potential for environmental accidents in this field. Changes in water quality are the most common pollution occurrence, and are able to cause toxic effects in these environments. The Hydrocarbon Polycyclic Aromatic (HPAs), oil derivatives found in estuarine waters, are regarded as a primary organic pollutant in environmental studies due to their high contamination and intoxication potential, which is associated with the increase in the incidence of several kinds of cancer in the human being. Therefore, this study aimed to determine the kinetics of acute HPAs toxicity in marine microcrustaceans, thus enabling the improvement in the decision-making process regarding preventive and corrective action related to leakages or accidents with these compounds within a marine environment. Since this work focuses on obtaining data in order to contribute with information that might help in the turnaround time regarding environmental accidents of the oil sector in marine environment, the option was made to work with the marine microcrustacean Mysidopsis juniae. The lethal concentration (CL50) was determined through an acute toxicity rehearsal based on NBR 15.308 (ABNT, 2011). From the determination of the lethal HPA concentration in the sample concerning the CL50 of the tested organism, the HPA concentration was determined in CL50 by using a fluorimetric probe. The results show that the lethal HPA concentration for the tested organism is of approximately 0.023 ppm, and that the time elapsed for the death of 50% of the population is of approximately 48 hours, i.e., from the initial leakage time, there are 48 hours for the execution of mitigation actions, thus avoiding greater damage to the trophic chain, and, consequently, for the whole ecosystem.
