Current surveillance plan for persons handling nanomaterials in the National University of Singapore.

Abstract

The number of research projects involving engineered nanomaterials within the National University of Singapore is increasing. We aim to characterize typical exposures in our laboratories and to develop a health surveillance protocol for persons working with nanomaterials in this project that has recently been launched. Our surveillance project builds on existing occupational safety and health risk assessment systems in the National University of Singapore. Environmental monitoring will be conducted in all laboratories handling nanomaterials, encompassing airborne nanomaterial concentrations, characterizing chemical and physical properties and assessing dermal exposure potential and significance. Health surveillance will initially follow the occupational health program already in place, to be progressively fine-tuned as more nanotoxicity data become available. Our vision is to build an adequate base for a cohort study that can provide good data on the health outcomes of nanomaterials-exposed persons.
