Environmental Fate and Behavior

Environmental fate describes the processes by which chemicals move and are transformed in the environment:

•    Persistence in air, water, and soil
•    Reactivity and degradation
•    Migration in groundwater
•    Removal from effluents by standard wastewater treatment methods
•    Bioaccumulation in aquatic or terrestrial organisms

Residue studies

Residue studies can evaluate the degree of environmental impact of your product during a specified timeframe and conditions.

All methods to assess ready biodegradability of chemical substances in aerobic aqueous medium are performed in accordance with OECD 301 guidelines in water or in soil/compost.

The following studies are performed in accordance with REACH, the European regulation on Registration, Evaluation, Authorization and Restriction of Chemicals:

•    Biotic degradation
•    Ready biodegradability
•    Abiotic degradation
•    Hydrolysis as a function of pH
•    Fate and behavior in the environment
•    Adsorption/desorption screening

Soil and water behavior

We perform studies to determine the behavior of agrochemicals on soil and water, using cold (unlabeled) or radiolabeled molecules (14C and 3H):

•    Adsorption/Desorption
•    Photolysis
•    Hydrolysis
•    Mobility
•    Aerobic transformation – biodegradability
•    Anaerobic transformation
•    Bioaccumulation in aquatic species, preferably fish
