Organic matter modifies biochemical but not most behavioral responses of the clam Ruditapes philippinarum to nanosilver exposure
چکیده انگلیسی
Adsorption of dissolved organic matter (DOM) can alter the environmental fate, bioavailability and toxicity of silver nanoparticles (Ag NPs). However, a number of questions remain about DOM's ability to modify nanotoxicity. Here, we examine the impact of humic acid (HA, as a model DOM) on the toxicity of Ag NPs (10 μg L−1) in the marine clam Ruditapes philippinarum. Results showed that DOM additions to Ag NP treatments reduce clam silver tissue burdens and the oxidative stress response. However, HA does not significantly affect the impact of Ag NPs on clam acetylcholinesterase activity and feeding behavior (measured as filtration rate). Overall, the integrated biological response index supports the conclusion that humic acid reduces the toxicity of Ag NPs, clearly indicating the importance of considering environmental factors when assessing potential risks posed by nanomaterials in natural settings.
