PUB: Review of the potential distribution of engineered nanoparticles in aquatic environment

Engineered nanoparticles in the aquatic environment

PUB_200The objective of this project was 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 aimed to 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 was built that can be used to support a knowledge based approach for effective policy development.

The project was supported by PUB, Singapore's National Water Agency, and completed at the end of 2014.

Results of the study have been published as an article in the International Journal of Environmental Research and Public Health.
