OUTLINE: 1. MATCH PROJECT 2. Health Implications of PAH in Indoor Environments 3. SPADE PROJECT Dr Juana Maria Delgado-Saborit Division of Environmental Health and Risk Management School of Geography, Earth and Environmental Sciences University of Birmingham

 OBJECTIVES:  Quantify the magnitude and range of individual personal exposures to a selected group of air toxics (VOC & PAH)  Develop models for exposure prediction based on time/activity diaries and micro-environmental concentrations MATCH PROJECT MATCH PROJECT- M easurement and modelling of A ir T oxic C oncentrations for H ealth effects and verification by biomarkers  METHODOLOGY:  Personal Exposure Sampling  Time-Activity Diary  Microenvironment Monitoring  Biomonitoring  Model Development

 RESULTS: MATCH PROJECT URINARY BIOMARKERS R 2 =0.47 MODELLING PERSONAL & MICROENVIRONMENT

 OBJECTIVES:  Assess typical range concentrations and profile of PAH indoor & outdoors  Assess carcinogenic potency of PAH indoors & outdoors  Evaluate whether BaP can be used as a marker indoors Health Implications of PAH in Indoor Environments  METHODOLOGY:  Microenvironment Sampling – Indoors & Outdoors – MATCH  Calculate carcinogenic potency (CP) and % contribution of BaP to CP

Health Implications of PAH in Indoor Environments

 OBJECTIVES:  Source apportionment of PAH in ambient air  Assess contribution of long-range transport & local sources  Study the breakdown rates of PAH in the atmosphere  Assess levels of PAH reaction products: quinones SPADE PROJECT SPADE PROJECT – S ources and P rocesses determining polycyclic A romatic hydrocarbons and their D egradation products in the E nvironment  METHODOLOGY:  Gas and Particle phase sampling – PAH & Quinones  Remote sampling – HYSPLIT back-trajectories  Lagrangian experiment
