Engineered Nanoparticles in aquatic environment

Review of the potential distribution of engineered nanoparticles in aquatic environment


The objective of this project is to investigate the potential distribution of engineered nanoparticles (ENPs) in Singapore's aquatic environment through quantitative estimates of the presence of ENPs based on information on the use of ENPs-containing consumer products and their life cycle.

This project will provide

1) an understanding of the use and distribution of existing products containing ENPs in Singapore and where there is potential release into the water system;

2) an estimate of possible concentrations of ENPs in different water systems based on input from the use and distribution information and published information about removal during transmission to water, treatment, dilution and removal within the water body and;

3) a benchmarking of the probable levels of exposure to humans by comparing the estimates of this study with other estimates for human exposure through other routes.

Through this project, a comprehensive assessment on the probable levels of ENPs in water and potential human exposure will be built that can support a knowledge based approach for effective policy development.

The project is supported by PUB, Singapore's National Water Agency, and is due to complete in mid 2015. The principal investigator is Dr Michael Riediker.
