Micro- and nanoplastics in drinking water: tracking sources, fate, and removal

Plastic pollution is an emerging global challenge, with increasing evidence that very small plastic particles, particularly those smaller than 10 µm, can enter drinking water supplies and potentially be absorbed by the human body. Despite growing concern, there remains limited understanding of their occurrence, sources, and removal during water treatment and at the point of use.

This PhD project provides an exciting opportunity to investigate plastic contaminants (particles <10 µm) in drinking water systems across Australia and the globe. You will apply advanced analytical techniques to detect, quantify, and characterise micro- and nanoplastics in water samples. You will also explore key sources of these particles, including distribution systems and household materials.

A major component of the research will evaluate the effectiveness of water filtration systems in removing these contaminants. The outcomes will contribute to improving water quality management strategies, informing regulatory frameworks, and supporting evidence-based decision-making by water utilities and policy-makers.

This project is ideal for a motivated student interested in environmental pollution, human exposure, and cutting-edge analytical science, with opportunities to collaborate with leading national and international researchers.

This project will be based at the Queensland Alliance for Environmental Health Sciences (QAEHS) at The University of Queensland. QAEHS provides a world-class, multidisciplinary research environment with state-of-the-art laboratories and expertise in environmental chemistry, exposure science, and public health.

You will have access to advanced analytical instrumentation, including pyrolysis–gas chromatography–mass spectrometry (Py-GC/MS), spectroscopic techniques (e.g., FTIR, Raman, and O-PTIR), and clean laboratory facilities for trace contaminant analysis. The project also offers opportunities for collaboration with leading research groups and industry partners, as well as access to diverse environmental samples and datasets. T

You will join a cohort of >30 HDR students researching human and environmental exposure to environmental contaminants. You will be given access to a centre-level travel support award scheme supporting participation at international conferences.

You will receive full access to your own computer and workstation. In addition to the standard UQ living stipend of $37,500 per annum tax free (2026 rate, indexed annually) and tuition fees, there is also a top-up of $5000 per annum (for three years).
