Recommendations are given for the implementation of a set of default initial distribution fractions into LCI databases, for the organisation of metadata, and for the modelling of pesticide residues in food along the supply chain (processing, storage).

Results and discussionДЄ sensitivity analysis shows the effects of the application technique, drift reduction, crop and development stage, field width, and buffer zone on the initial distribution fractions of field-applied pesticides. Default emission fractions are provided to calculate the emission fractions for different pesticide application scenarios. Deposition on the crop surface should be recorded in an emission compartment crop with 13 sub-compartments for crop archetypes for both food and non-food uses. Emissions to off-field surfaces are hereby distributed between agricultural soil, natural soil, and freshwater by using surface cover data.

The initial distribution fractions should be linked to the compartments air, agricultural soil, natural soil, and freshwater. The PestLCI Consensus Model has been developed in order to estimate emission fractions to different environmental compartments. Based on this effort, we propose an approach to integrate pesticide emissions into LCI databases. The OLCA-Pest project was implemented to address these aspects and to operationalise the assessment of pesticides in LCA. Current field emission modelling and toxicity characterisation of pesticides suffer from several shortcomings like mismatches between LCI databases and LCIA methods, missing characterisation factors, missing environmental compartments, and environmental impact pathways.
