Fate studies

Environmental Fate studies investigate the interactions between coumpounds and the environment. These fate studies are typically designed for new chemicals, products or formulations not present in the market. GMW is evaluating the potential of the material to cause problems in the environment. Fate testing can be done for registration or label claims, such as “this material is readily biodegradable”.

Environmental fate studies in combination with ecological effects studies determine the environmental safety of a compound.

Using our network of contacts, we can assure inclusion of soils from all around Spain. A suitable test site selection, precise plot spraying, zero contamination sampling are carried out by GMW.

Our portfolio:

Soil dissipation studies

Soil dissipation studies provide estimates of the time needed for dissipation of 50% and 90% (DT50 or DT90) of the active ingredient under field conditions. These studies can be conducted in bare soil or in-crop in different climatic zones.Several options as randomised sampling, type of sampling, protective fence in the control plot to avoid contamination, drip irrigation application. Zero contamination soil corers are used.

GMW provides weather data on site in real time by means of a weather station on site; humidity coastal samples, soil and air temperatures, precipitation on site can be handled on request.

Soil accumulation studies

These studies are conducted to determine the potential of a substance to accumulate in soil after multiple application and can generally take several years. They are needed if values of DT50 of 3 months and/or a DT90 of 1 year in the field dissipation studies were not met.

Our Philosophy

The Quality Assurance Unit (QAU) is a main part of GMW; we use an independent Quality Assurance staff to monitor all studies (both in the laboratory and the field). Systems and processes are developed to increase organizational adherence to Good Laboratory Practices (GLP) and Standard Operating Procedures (SOP).

The Quality Assurance Unit monitors all phases of the study conduct and provides updates and recommendations that increase study quality, dead lines, and efficiency.
