Gary is a skilled environmental fate specialist and environmental risk assessor, having formed part of the scientific team at Brixham Environmental Laboratory (BEL) between 1985 and 2014 (ICI, Zeneca and then AstraZeneca). His broad experience encompasses a range of chemical industry sectors, including pesticides, biocides, pharmaceuticals and industrial chemicals.
Gary has served on European scientific committees including the EU Biocidal Products Directive Notes for Technical Guidance. Gary chaired the ECETOC (European Centre for Ecotoxicology and Toxicology of Chemicals) Task Force which developed interim guidance for the inclusion of Non-extractable Residues (NER) in environmental risk assessment. He was also a member of the ECETOC monitoring team overseeing the CEFIC (The European Chemical Industry Council) LRi (Long-range Research initiative) research project ECO 24 (prediction of NER formation using structural alerts and QSARs) and ECO 25 (the development of ecotoxicity tests for assessing the environmental risk of NER in soil).
Since joining RSA in 2016, Gary has contributed to projects on behalf of clients which have used QSARs and read across for predicting toxicology and environmental endpoints. He has also used these approaches to preform projects focused on the establishment of the residue definition for dietary risk assessment. Gary has conducted work packages assessing the validation of analytical methods for EU pesticide registrations and used his chemistry and environmental fate knowledge to contribute to pesticide CLH (Harmonised Classification and Labelling) projects.
