Abstract

Silver nanoparticles (AgNPs) with excellent physical and chemical properties are one of the most widely used nanoparticles (NPs). However, with the increase of the production of AgNPs, there will be certain risks to aquatic organisms when they are discharged into the water environment. Here, we systematically studied the ecotoxic effect of AgNPs on Tigriopus under the influence of humic acid (HA) in natural organic matter (NOM). From the perspective of individual level, the effects of AgNPs on feeding behavior of Tigriopus under the action of HA were explored. As a link between primary and higher nutrient levels in the ocean, it is of great significance to study the feeding behavior of copepods. Compared with acute and chronic toxicity indexes, behavioral indexes are more sensitive to evaluate the toxic effects of pollutants. With the increase of AgNPs concentration, the feeding rate and water filtration rate of Tigriopus decreased, indicating that the presence of nanoparticles (NPs) could significantly inhibit the feeding behavior of the tested organisms. The presence of humic acid (HA) alleviated the inhibition of AgNPs on feeding rate and water filtration rate of Tigriopus. In addition, this indicated that there was a certain interaction between NPs and HA, which would alleviate the toxic effects of nanoparticles on copepods, and ultimately affected the individual level and population dynamics of copepods.
