1. General description of programme and host

The PhD fellowship is part of the Marie Skłodowska-Curie Actions (MSCA) COFUND doctoral programme INNOCHEMBIO (https://taltech.ee/en/innochembio), which is co-funded by the European Union (Grant agreement 101217295). The main objective of INNOCHEMBIO is to train future experts to help Europe take the next steps in the green transition. The solutions and trained experts can reduce the environmental impact of the chemical and agricultural industries, offer eco-friendly analytical techniques, and assess the safety of new materials. INNOCHEMBIO funding will co-finance 15 PhD positions, for which the application process in the first call will start on the 1st of July in 2025.
For 12 PhD positions the hosting institution will be Department of Chemistry and Biotechnology (DCB) at Tallinn University of Technology (TalTech) which combines three divisions – Chemistry, Gene Technology and Biomedicine, and Food and Biotechnology. DCB is developing solutions to the great challenges of the 21st century – climate change, environmental protection, carbon neutrality, renewable energy, and biodiversity conservation. DCB hosts the second biggest PhD programme in TalTech with nearly a hundred enrolled students.

For 3 PhD positions the hosting institution will be the implementing partner – National Institute of Chemical Physics and Biophysics (NICPB). NICPB is a public research institution that conducts both fundamental and applied research, developing novel directions in fields ranging from material sciences to informatics. NICPB houses the Laboratory of Environmental Toxicology and several laboratories focused on fundamental research in NMR technologies with expertise dating back decades. The PhD training activities conducted by NICPB are funded through TalTech.

Importantly, each PhD project has one co-supervisor from another European country, which is detailed under the specific offer (see under supervisors' section). In total, INNOCHEMBIO has 19 associate partners from 11 European countries.

2. Description of specific PhD project

Sustainability of plastics cannot be achieved without evidence-based knowledge on potential hazards regarding both the chemical makeup of the material as well as physical effects of plastic particles (nano/microplastics). By the current knowledge, over 16 000 chemicals have been associated with plastics. Monitoring studies have shown ubiquitous presence of microplastics and the largest group of plastics functional additives - plasticizers.

The ESR project is about environmental hazard analysis of selected plastic additives (and nano/microplastic) in environmentally relevant exposure settings. The aim is to mimic potential exposure scenarios but also to analyse the potential toxicity drivers/mechanisms. Due to the number of open questions in plastic hazard research, the hypotheses can be formulated jointly by the supervisors and the ESR, depending on his/her background.

For instance, whether to focus on aquatic or terrestrial biota; on plastic additives or micro/nanoplastics. Also, the polymer types will be selected together in the final planning phase. The number of plastics additives is high and compared to microplastics, it is a considerably understudied field. As the biological effects of nanoplastics is another potential research avenue, experience in nano(eco)toxicology or hazard evaluation of particulate contaminants is beneficial.
