Environmental Fate

Battelle assess your product risks and helps you meet global product registration requirements with accurate, defensible data. We provide a range of services for agrochemical developers and producers, from single studies to complex, whole programs, including dossier preparation and submission. 

Applications

An understanding of the environmental fate processes can help every pesticide producer ensure that applications are not only effective, but are also environmentally safe. Battelle’s expertise provides the data you need to make product development decisions and obtain product registrations.

Battelle can help you generate accurate, defensible data for global registration.

Features

Our multidisciplinary teams combine decades of agrochemical industry experience with world-class technical expertise and analytical capabilities. We operate in GLP-compliant facilities across the U.S. and Europe providing regulatory compliant studies for submission in all geographic regions.

When you need to know potential risks, and meet regulations, we can:
  • Ensure accuracy of outcomes
  • Assess risks
  • Meet regulatory guidelines
  • Provide detailed insight into product behaviors

Services

Our services include the provision of a full range of environmental fate studies to standard guidelines (OECD, OCSPP, JMAFF, etc.) along with higher tier, non-guideline studies designed to investigate specific issues with the potential to refine environmental risk assessments. Standard study types include:  

Metabolism in soil
Standard, guideline compliant studies to meet global regulatory requirements under aerobic, anaerobic and paddy conditions with soils collected from an appropriate region. Dependent upon specific requirements, studies can be conducted with radiolabelled or non-radiolabelled test items. We offer flow-through and static designs with samples incubated in temperature-controlled rooms in the absence of light. Small plot studies with radiolabelled test items also can be performed outdoors under prevailing weather conditions.

Soil dissipation
Field studies to determine how products degrade and dissipate in soil under typical use conditions. With a network of field cooperators across Europe, the U.S. and beyond, we offer a full range of dissipation, accumulation and field leaching studies. 

Metabolism in aquatic/sediment systems
Standard, guideline compliant studies to meet global regulatory requirements under aerobic or anaerobic conditions. We also have facilities to conduct higher tier studies either in the laboratory or outdoors under more realistic environmental conditions. The degradation (mineralisation) in biotic aquatic systems also is investigated.
 
Mobility in soil
Standard guideline compliant adsorption/desorption studies to provide accurate data for groundwater risk assessments. Higher-tier aged desorption studies also can be performed to provide data for refinement of risk assessments. Alternative studies to provide an insight into leaching potential, including column leaching or lysimeter studies, also are available.


Hydrolysis
Studies to meet international regulatory guidelines with fully compliant hydrolysis testing under sterile conditions. High temperature (processing) hydrolysis studies also are available.

Photolysis
Studies to investigate the influence of sunlight either on soil or in an aqueous environment using Hereaus Suntest artificial sunlight sources and a choice of static or flow-through designs. 

Volatility
Studies to investigate the volatility of a chemical from a variety of matrices such as soil or water. 

Benefits

Whether your needs are standard or non-standard, Battelle can give you accurate data for confident risk assessment and product registration. We’ll help you reduce risks and meet regulatory requirements.

Improving Environmental Fate Models for Agrochemicals

Challenge

Before making a pesticide or other agrochemical available on the marketplace, agrochemical companies need to fully understand the potential fate of the chemical in the environment.  In the case of pesticides, the potential for the chemical to leech into groundwater is of particular concern. Currently, computer simulations utilizing data about soil characteristics and weather conditions at various locations are used to predict pesticide concentrations under different conditions.  Lab data, including information about the rate of degradation and sorption properties, is used to build the computer models.  However, inaccurate assumptions in the model will lead to incorrect conclusions about the environmental fate of the pesticide, potentially unnecessarily jeopardizing registration, or resulting in unsafe application recommendations.

Solution

The standard models assume that sorption is due only to binding to the organic matter in the soil.  In lower horizons of soil, the organic matter is approximately zero, and thus no sorption is assumed.  In reality this may not be entirely correct when other mechanisms of sorption are taken into consideration. 

Battelle looked at one of the standard scenarios used to assess pesticide leaching, the “Borstel” model.  This is considered to be one of the more critical scenarios, as it is a very sandy soil and represents a greater risk for leaching into groundwater.  To provide data to refine the simulation, Battelle collected “Borstel” soil as a core down to 1m.  The core was segmented and each horizon analyzed to confirm its similarity to the soil characterization data used in the computer simulation.  Each soil horizon was then used in an adsorption/desorption study to determine the actual sorption of the chemical.  The measured sorption in the deeper soil horizons was found to be greater than predicted by assuming organic matter binding as the sole mechanism, leading to a more favorable leaching risk assessment. 

Outcome

Using the new lab data, we were able to refine the assumptions used in the computer model to provide a more realistic risk assessment of potential leaching.  The refined modelling can be used to make better decisions about application recommendations, and provide critical data necessary to maintain product registration or move into new market areas.
