Sciences has a large and diverse practice in exposure assessment, one of the most important and perhaps underappreciated elements of the risk assessment paradigm. Scientists at our firm are experts in many of the latest methodologies and guidance in exposure assessment, including the modeling of the fate and transport of environmental substances in air, water, and soil. Some key project areas include:

• Air dispersion modeling to estimate downwind concentrations of environmental substances from industrial sources.
• Site exposure assessments using Superfund guidance.
• Modeling the fate of indoor air pollutants.
• Development of advanced environmental exposure models and software.
• Multimedia exposure assessment.
• Environmental chemistry.
• Food chain, bioaccumulation, indirect exposure analyses, and bioavailability.
