· Abstract

· Along with the increasing utilization of engineered nanoparticles, there is a growing concern for the potential environmental and health effects of exposure to these newly designed materials. Understanding the behavior of nanoparticles in the environment is a basic need. The present study aims to investigate the distribution and fate of ceria nanoparticles in an aquatic system model which consists of sediments, water, hornworts, fish and snails, using a radiotracer technique. Concentrations of ceria in the samples at regular time intervals were measured. Ceria nanoparticles were readily removed from the water column and partitioned between different organisms. Both snail and fish have fast absorption and clearance abilities. Hornwort has the highest bioaccumulation factors. At the end of the experiment, sediments accumulated most of the nanoparticles with a recovery of 75.7 ± 27.3% of total ceria nanoparticles, suggesting that sediments are major sinks of ceria nanoparticles.

· Highlights

· ► We simulated a freshwater ecosystem in laboratory. ► A radiotracer technique was used as the quantitative method. ► Distribution and fate of ceria NPs in the aquatic ecosystem model were studied. ► Hornworts, snails and fish quickly accumulated and desorbed the ceria NPs. ► Sediments were found to be the ultimate sink of ceria NPs.
