Mechanisms of response to silver nanoparticles Enchytraeus albidus (Oligochaeta): survival, reproduction and gene expression profile


ABSTRACT: Due to its antimicrobial activity, silver nanoparticles (Ag-NPs) are among the most used NPs worldwide, yet little information is available regarding their effects, particularly in soil dwelling organisms. Enchytraeids (Oligochaeta) are important members of the soil fauna which actively contribute to the acceleration of organic matter decomposition and nutrient recycling processes. Hence, for hazard and risk assessment it is important to provide toxicity data for these organisms and to understand more in regard to the mode of action of Ag-NPs within organism. To study this we conducted toxicity experiments using the OECD standard guideline, testing Ag-NPs and AgNO3, having assessed survival, reproduction and differential gene expression. Population toxicity responses were assessed showing higher toxicity for the AgNO3. In an attempt to understand the mode of action we performed transcription profiling using the microarray.
