Abstract

Atmospheric particulate matter (MPA) pollution can be transferred to aquatic ecosystems through precipitation. The study sought to investigate whether the increase in MPA concentrations and whether the exposure time could cause physiological disturbances. Exposures to MPA were carried out over 30 days at concentrations (Control, 0.01; 0.1; 1 g L-1). Glucose, lactate, osmolarity and ion analyzes were performed on the hemolymph. Concentrations and times were not able to change glucose, lactate, osmolarity and ions. However, K+ and Ca+2 showed dose- and time-dependent changes, demonstrating that some metals present in MPA can alter the active and passive sites of absorption/excretion of these ions, leading to physiological disorders.
