Determination of the key parameters influencing dislodgeable foliar pesticide residues
An exciting and unique opportunity for a PhD is now open for applications. Pesticides are a vital tool in meeting the challenge of feeding the rapidly increasing world population. However, it is vital that they are used in a way which does not compromise the safety of humans or the environment. To this end, rigorous assessment of the risks involved is carried out to satisfy the demands of regulatory authorities and other stakeholders. The population can become exposed to pesticides in many different ways but farm works are particularly at risk. Exposure assessment for farm workers takes into account, amongst other factors, the amount of residue which can be transferred from plant foliage to the skin or clothes. These type of residues are known as a Dislodgeable Foliar Residues (DFRs). Understanding DFRs is important for evaluating the occupational exposure of farmers in their working environment, for example, by establishing the period of elapsed time needed following greenhouse spraying before it is safe to re-enter. Additionally, such data are used to ensure that members of the public entering treated crops do not encounter unacceptable risk. Previous research has shown that there is a relationship between the proportion of residue that is dislodgeable and a range of factors including the pesticide application rate; chemical characteristics; the product formulation; the environmental conditions including temperature and humidity; and the plant architecture and leaf type. However, these issues are not fully understood, therefore the purpose of this 4-year work programme is to explore some of these issues with the intention of enabling the refinement of re-entry risk assessments. The work is expected to include analysis of existing large datasets, glasshouse, laboratory and analytical work.
The successful applicant will spend their first year based at Syngenta’s prestigious international research centre at Jealott's Hill, Berkshire whilst also undertaking studies in research skills, on a day release basis, at the University of Hertfordshire. The subsequent 3 years will be based at the University of Hertfordshire undertaking a PhD with time spent at Jealott's Hill as the research demands.
