Ms. Tomlinson has 14 years experience in pesticide and biocide regulation in the EU. She has undertaken ecotoxicological data-gap assessment for EU submissions, monitored required additional studies, and written ecotoxicological data summaries. She has experience in the evaluation of ecotoxicological data, for pesticides, biocides and REACH chemicals, under Directives 91/414/EEC and 98/8/EC and Regulation (EC) No. 1907/2006 respectively. She specialises in the production of appropriate environmental risk assessments for both pesticides and biocides in Europe and has developed a number of higher tier risk assessment solutions. She has provided environmental classifications for various pesticide products according to the Dangerous Preparations Directive (99/45/EC) and according to the new globally harmonised system of classification and labelling of chemicals (GHS). She co-ordinates client updates on the impacts of the Water Framework Directive (2000/60/EC) and its daughter directives with respect to priority substances.
Prior to joining Exponent, Ms. Tomlinson worked at the Pesticides Safety Directorate (PSD), the UK regulatory authority for pesticides for six years. She was responsible for the evaluation of a range of data, conducting environmental risk assessments and providing technical advice to a variety of bodies including agrochemical companies, contractors and other Government departments. She undertook a comparative aquatic risk assessment for the pesticides used during the storage of ware potatoes in the UK on behalf of PSD as part of her M.Sc. degree in Ecotoxicology.

Selected Reports
Brown K, Tomlinson J, Duncan J, Hinchcliffe A, Palmquist K. Critical comparison of available and potential higher tier testing approaches for the risk assessment of plant protection products, considering at least field and semi-field experimental designs, extrapolation from dose-response relationships, and increased dosages (aquatic and terrestrial). Exponent report prepared for European Food Safety Authority, August 2009 as part of the Literature reviews on ecotoxicology of chemicals with a special focus on plant protection products. Reference CFT/EFSA/PPR/2008/01: Lot 4.

Written regulatory ecotoxicology risk assessments for various pesticides, biocides and REACH chemicals under Directives 91/414/EEC and 98/8/EC and Regulation (EC) No. 1907/2006 respectively. Where required, has included the accurate summarisation and interpretation of data studies. Developed higher tier risk assessment solutions for a number of these projects in both the aquatic and terrestrial environments.
Identified ecotoxicology data-gaps for a review pesticides and biocides and effectively monitored studies to address the gaps and their evaluation in the risk assessment to meet a tight deadlines.
Supplied environmental classification of pesticide products according to the Dangerous Preparations Directive 99/45/EC and new globally harmonised system of classification and labelling of chemicals (GHS).
Undertaken a comparative aquatic risk assessment for the pesticides used during the storage of ware potatoes in the UK.
Acted as report writer at an EU Ecotoxicology expert ECCO meeting convened to discuss 8 active substances (new and existing).
Written regulatory evaluations (monographs, evaluation documents) of environmental fate and behaviour data in support of new and existing active substances under the EU Directive 91/414/EEC.
Written regulatory evaluations of physicochemical and analytical methodology data in support of applications for pesticide product approvals in the UK under both the Control of Pesticides Regulations (COPR) and the EU Directive 91/414/EEC.
Undertaken upgrades and changes to National pesticide approvals in the UK.
Developed structured and systematic literature surveys.
Conducted laboratory research work to investigate the control of the xanthophyll cycle in maize (
Zea mays) chloroplasts.
