TOPIC 7: Environmental Fate, Transport and Metabolism

Environmental fate processes have a pivotal role in the efficiency of pesticides and their dispersal to various environmental compartments (soil, air, water). Topic 7 will focus on (i) the underlying biotic and abiotic processes which drive the environmental fate and dispersal of pesticides at various scales (lab-to-field-to-landscape), (ii) report advances on pesticide monitoring using innovative approaches, sampling methods and analytical tools to determine the whole range of pesticides and transformation products released in natural resources (iii) present an update on mathematical modeling to predict environmental exposure by pesticides at various sca es addressing all receiving environmental compartments (soil, air, water), (iv) the environmental fate and behaviour of emerging pesticide groups like nanopesticides and pesticides of biological origin and (v) the potential interactions of pesticides with other environmental contaminants (pharmaceuticals, antibiotics, industrial chemicals) and the environmental behavior of pesticide mixtures and formulations. A dedicated session of topic 7 will deal with the implementation and evaIuation of the efficiency of measures and management practices to mitigate pesticide emissions to water bodies and air. Key regulatory issues including harmonization of tests and updates on pesticide monitoring studies around the globe will be also addressed. The topic will attract people from all sectors (academia, industry and regulatory bodies) which are interested in getting a holistic view and update on the state of science regarding the different aspects of environmental fate of pesticides.
