Project Description
Plastic pollution represents a global environmental challenge. The larger plastic particles can degrade to produce/release nanoplastics (NPs) that can enter the tissues of aquatic organisms. For example, up to 700,000 nanoplastics can pass across the gut of fish in four hours and once in the body, these NPs can enter the internal organs. However, linking accumulation with the effects on the gut epithelium, and the cellular storage and remobilization (i.e., excretion) following chronic exposure, remains unexplored.
Contaminants such as NPs do not occur in the environment in isolation and the presence of other particles will affect their bioavailability and toxicity. Recently, engineered nanomaterial (ENM) production has increased, including zinc oxide (ZnO) due to its advantageous properties (e.g., piezoelectricity, semiconducting, antibacterial) and these ZnO particles can interact with larger microplastics through surface sorption. However, the interaction of ZnO with smaller scale plastic pollution (i.e., NPs), and the subsequent consequence for animal exposure (e.g., uptake and toxicity) remains unclear.
This project will understand the dietary exposure of NPs and ZnO co-exposure in fish through characterising the dynamics of NP and ZnO interactions in artificial gut fluids (stomach and intestines) and assessing the chronic toxicity and accumulation to fish using in vitro and in vivo methodologies.
The time for this project will be split across the University of Plymouth (50%) and Diamond Light Source (50%). Please note that the successful applicant will be based 2 years in each institution with no full-remote working allowed.
Eligibility
Applicants should have a first or upper second-class honours degree in an appropriate subject or a relevant Masters qualification. Knowledge of either Biology, Toxicology or Chemistry laboratory working processes and safety procedures is a must, including experience in how to write/follow Risk Assessments and (Bio)COSHH forms.
Regrettably, for this studentship, we are unable to accept international students because the necessary immigration visa licences are not in place. Citizens of Ireland can exercise Common Travel Area rights (and do not require a student visa to study in the United Kingdom).
The studentship is supported for 4 years and includes full Home tuition fees plus a stipend of £18,110 per annum 2023/24 rate (2024/25 rate TBC). The studentship will only fully fund those applicants who are eligible for Home fees with relevant qualifications.
