IMPACTS OF PARTICULATE MATTER (PM2.5) ON THE BEHAVIOR OF FRESHWATER SNAIL PARAFOSSARULUS STRIATULUS
Fine particulate (PM2.5) is a severe problem of air pollution. Although PM2.5 effects on human health were examined, the understanding of PM2.5 influence on aquatic organisms is limited. PM2.5 through wet deposition can enter aquatic ecosystems and affect aquatic organisms. This study tested the hypothesis that PM2.5 will negatively affect the behavior of freshwater snail Parafossarulus striatulus (Benson, 1842). Along with PM2.5, a number of components (Al, Pb, and Zn) that are commonly present in PM2.5 were also tested for their effects on snail behavior. The snail behavior was scored using the Behavioral State Score (BSS), ranging from 0 (no movement) to 5 (active locomotion and fully extended body). The result shows that a high PM2.5 concentration dose (7.75mg/L) induced a significant decrease in snails’ movement behavior, and such reduced movement behavior was also observed for treatments with chemical components related to PM2.5, including aluminum and acidity (pH5.0). At a low concentration dose of PM2.5 (3.88mg/L), lead, and zinc do not significantly affect snails’ behavior. The results suggest that high PM2.5 deposition in water bodies, associated with acidification and some metals, can have an adverse effect on aquatic organisms.
