Human Exposure
Assessments and Risks

We focus on refinement of human exposure
assessment for better risk characterization.

Our research strategy

Human health is affected by several factors to which we are exposed on daily basis. One of the most important factors of concern are chemicals, pollutants and their mixtures which enter our body via oral, dermal or inhalation route and are subject to physiologicaly based pharmacokinetic processes that may affect their absorption, distribution, metabolism and excretion.

The fate of these substances in the human body, reactions at the site/mode of action, can cause risks to human health. Therefore, it is important to measure external exposure, but also to focus on internal exposure. Our group is dedicated to identify chemicals that can potentially enter the human body, modeling and predicting their pathways in the human body, subsequently assessing real health risks and also to analyze potential relationship between exposure and health outcomes in individual (cohort studies) and population levels. Our goal is to assess and refine human exposure in order to better characterize the risks.

URBAN Exposome

Key words:Urban populations, urbanization, exposure, pollution, noise, adverse health effects

Other research topics

  • Retrospective exposure assessment – the use of biomonitoring studies for retrospective reconstruction of exposure by PBPK modeling (biomonitoring of breast milk in the human population in CR) and probabilistic human health risk assessment.

  • Indoor air sampling & inhalation risk assessment – exposure assessment of new POPs. Probabilistic risk assessment in human population (MonteCarlo simulation – Risk assessment) 

  • The Experimental ex-vivo approach: on fully automated Franz cell system with human skin (Dermatotoxicokinetic parameters). 

  • Targeted studies for refinement of exposure of selected chemical substances – SkinRISK project (Kinetics of the percutaneous penetration of optical isomers in sunscreens, brominated flame retardants and polar pesticides in dermal exposure) and use of these parameters for toxicokinetic (PBTK) models. 

  • Toxicological characterization of UV filters – sunscreens – its fotodegradation products and optical izomers. 

  • The development of new methods for external exposure assessment – ambient air – SENSORS – SMART CITIES.
