Assessing Exposure to Chemical Substances

Development of Pharmacokinetic and Exposure Reconstruction Models for Chemical Substances

• Building  pharmacokinetic and exposure reconstruction models that link the concentration in biological samples from human biomonitoring and the estimated exposure amount via environmental media
• Analyzing the concentrations of phthalates and other chemicals in house dust, food, consumer products, etc. for exposure assessment
• Development of a system for estimating the effects of exposure on human fertility as health outcome

 

 

Exposure and Risk Assessment for Complex Mixture

Comprehensive Analysis of Mixtures by State-of-the-Art Technology

• Development of analytical methods using state-of-the-art instruments (e.g. GC × GC) to comprehensively clarify chemical composition of mixtures occurring in the environment and in commercial/industrial products
