Taking Environmental Fate Modelling to the Next Level
Acre now provides crop protection product developers with faster, easier and more cost-effective access to multiple data sets on environmental risk assessment than has been possible to date. A key feature of the system is the simplicity of its data tables, which allow product developers to take in complex information at a glance. A product of Enviresearch’s innovative approach to environmental modelling, Acre is the result of extensive research and investment.
With the introduction of Acre, environmental risk can be evaluated across entire crop databases in one sweep (what we term 'GAP Analysis'). With GAP Analysis, protection product developers can now draw upon a service that will help them pinpoint opportunities more accurately than ever before. Environmental risk can be considered at the start of the product development cycle. This cuts the risk of time and money being wasted on a new product that never gets to market. Acre will run the whole suite of FOCUS crops in the ground water model PELMO and in the standard surface water models at FOCUS STEP 3 and STEP 4. The Acre GAP Analysis report will demonstrate the risk profile of your product over the full range of potential uses. The commercial impact of potential mitigation options can be evaluated well in advance of dossier submission.
Key Benefits of Acre:
- Modelling time vastly improved
- Single interface screen
- Consistency across multiple runs

Mixture Toxicity Calculations and Integrated Risk Reporting-Improving Formulation Assessments with Acre.
Acre, Enviresearch’s innovative surface water risk assessment framework, has been designed to deliver maximum value for formulation risk assessments. Acre executes the standard FOCUS models (PRZM, MACRO, TOXSWA) to deliver the same environmental fate values you would achieve via the standard means but in a more efficient manner which is less prone to error. However the real value lies in the way it has been optimized to consider complete formulation assessments. The entire potential use pattern for a product, including mitigation options, is defined in a single step which is then applied to all relevant actives. In practice this facilitates formulations with complex usage patterns and/or multiple actives to be assessed both more efficiently and with greater precision.
An area where we have found Acre particularly useful is in the assessment of formulations with multiple active substances. Acre eliminates the need to manually split projects based on active substances so all calculations are completed in a single harmonized step. Aquatic effects endpoints can be included in this assessment such that exceedances are automatically identified. This can be done for the full mixture/combination toxicity assessment as well as the individual substances providing a single summary table which covering the complete risk profile of a formulation. An example summary output table showing environmental fate and toxicity calculations for a two-way mixture formulation is provided below.
Being able to quickly look at the data in this format has a number of potential advantages, but the becomes especially powerful when coupled to Acres ability to cross reference member state specific requirements for both scenarios and refinements. As Acre can run any number of Step 4 mitigation options in parallel with the Step 3 assessments it is possible to precisely match the minimum mitigation required to pass an assessment on a member state level without having to run numerous Step 4 runs in series. This saves time and removes the guess work from formulation optimizations.
