There are two main themes ongoing in our research group. The first theme is related to the evaluation of environmental health impacts of emerging chemical substances such as nano- and micro-plasctics, and the other is the innovation of energy-saving nanomaterials in the photo- and electro-catalysis of persistent organic contaminants. The current focus in emerging chemical substances is to evaluate their environmental release, bioaccumulation potential and toxicity. We develop novel probability material flow analysis (PMFA) in combination with the environmental fate models to predict the environmental expsoure of these emerging substances. We also develop new metrologies such as the single-particle ICP-MS methods to characterize nanomaterials and nano-(micro)-plastics in the environment and biota to assess their exposure and bioaccumulation potential from a life-cycle perspective. Cost-effect Quantitative Structure-Activity Relationships (QSARs) models are also being developed and evaluated in related research.
