Higher Tier Tests

The implementation of higher-tier studies in ecological risk assessment of plant protection products is a key area of gaiac. We offer a wide range of higher-tier approaches to refine the risk assessment for aquatic and terrestrial compartments:

• Tests with non-standard test organisms for species-sensitivity distributions (SSD)
• Population studies with Daphnia magna unter realistic exposure conditions
• Tests with complex aquatic communities under laboratory conditions (microcosms)
• Tests with complex aquatic outdoor communities (mesocosms)
• Tests with complex terrestrial communities in model ecosystems (TME) under outdoor conditions
• Ecological modelling of populations and communities

All higher-tier studies are conducted according to international guidelines or recommendations and, on request under Good Laboratory Practice (GLP).
