Fate and behavior of microplastic in natural environment; interaction between microplastics and SPM; influence of microplastic on the flocculation process.
My research focused on the environmental fate and behavior of microplastics in natural environment for three years during my master’s study (Tianjin University) and working experience in Finland (Lappeenranta-Lahti University of Technology). I have investigated microplastic pollution in different regions in China, including Bohai Bay coast, estuaries in Tianjin City and Yangtze River. I have also studied the interaction between the microplastic and particles from natural environment, including biological and non-biological particles to understand the influence of these processes on the fate of microplastics.

My PhD topic is to understand the association between micro/nano plastics (traditional and biodegradeable microplastics) and natural suspended sediment aggregates and the potential impact on both plastic and sediment fate. The state-of-the-art correlative 3-dimensional tomography techniques (Focussed ion beam nanotomography and X-ray computed microtomography) will be used to capture, observe and characterise the plastic-sediment suspended aggregates formed. Coupled to a settling column and floc camera system, the impact on microplastic and sediment settling behaviour will also be quantified.
