Soil dissipation/accumulation or TFD studies

Field soil dissipation studies, sometimes known as terrestrial field dissipation (TFD) studies, are conducted to establish the transport, transformation and fate of pesticides under representative field conditions, as opposed to laboratory studies, where pesticides may dissipate at different rates. This provides vital information on formation and decline of metabolites and offers an indication of leaching potential and accumulation of residues in soil.

Dissipation studies are key requirement for regulatory bodies, including the EU. All study designs comply with OECD and EPA guidelines and EFSA and NAFTA guidance documents.
