About

Dr Delgado-Saborit is an expert in exposure assessment studies using different sampling and analytical techniques to characterize inhalation doses, personal exposures and environmental levels of air pollutants. She has expertise in chemical speciation for source identification. She has coordinated large projects involving recruiting and sampling with subjects, sampling in a wide range of indoor and outdoor micro-environments, and using biomarkers as tracers of exposure to air pollutants.

Qualifications

  • MEng in Chemical Engineering (Universitat Jaume I, Spain)
  • MSc in Industrial Environment Engineering and Management (AINIA & School of Industrial Organization, Spain)
  • PhD in Environmental Sciences (Universitat Jaume I, Spain)

Biography

Dr Juana Maria Delgado-Saborit did her undergraduate and postgraduate studies at Universidad Jaume I (Spain). Shortly after completion of her MEng degree in Chemical Engineering she was awarded a fellowship to undertake doctoral studies. During her PhD studies, Dr Delgado-Saborit did two research stages at prestigious centers, the Harvard School of Public Health (USA) under the supervision of Professor Petros Koutrakis, and the Division of Environmental Health and Risk Management – University of Birmingham (UK) supervised by Professor Roy Harrison. After graduating with honours from her PhD studies, she started working as a Research Fellow in the latter research group. During her work at the University of Birmingham she has coordinated several projects funded by the Health Effects Institute, NERC, MRC and Cefic.

Dr. Delgado-Saborit was awarded the 2010 Long Range Initiative Innovative Science Award, a coveted award for young researchers, for her research proposal "In quest of new fingerprints of exposure to VOC from consumer products". The award is granted by the European Chemical Industry Council (Cefic), in conjunction with the Association of European Toxicologists and European Societies of Toxicology (EUROTOX), the Society of Environmental Toxicology and Chemistry (SETAC), the International Society of Exposure Sciences (ISES) and Chemical Week.

Dr. Delgado-Saborit was awarded the 2011 Walter A. Rosenblith New Investigator Award. This is a very prestigious award given by the American Health Effects Institute to support the work of young researchers who possess outstanding research potential.

Research

Dr. Delgado-Saborit’s research interests are the measurement and modelling of inhalation doses and personal exposures to air pollutants and related health effects; the use of biomarkers as tracers of exposure and effects to air pollution; the monitoring and assessment of air pollution in indoor microenvironments and ambient air; the characterization of airborne nanoparticle exposures and related health effects; the implementation of real-time sensors and passive samplers to assess air quality and human exposures to airborne pollutants; and the study of sources and processes determining airborne pollutant concentrations in indoor and ambient air.

Her recent research projects are:

Use of real-time sensors to assess misclassification and to identify the contribution of main sources to peak and chronic exposures funded by the Health Effects Institute 2011 Walter A. Rosenblith New Investigator Award. The aim is to assess the degree of misclassification associated with the use of surrogate measures of exposure — such as measurements made at central monitors — and to identify key activities and sources of these pollutants. A panel study will be conducted to improve methods of estimating human exposure to the air pollutant mixture (specifically ultrafine particulate matter [PM], fine PM, black carbon, and nitrogen dioxide). The subjects will wear personal monitoring equipment for four consecutive days in winter and summer. A novel feature of this study is the use of sensors that can provide detailed data on pollutant concentrations over time and accelerometers to estimate subjects’ physical activity level so that equivalent respiration rates and inhaled doses can be calculated.

Development of in-vivo and in-vitro methodologies to assess oxidative stress caused by ambient pollutants funded by the Wellcome Trust Institutional Support Fund. The aim is to develop an analytical methodology suitable to detect multiple oxidative stress biomarkers both in-vivo and in-vitro systems and to apply this methodology to assess the association between oxidative stress and inhaled exposures to pollutants.

In Quest of New Fingerprints of Exposure to Air Toxics (FIXAT Project) funded by the Cefic 2010 LRI Innovative Science Award and subsidized by the Division of Environmental Health and Risk Management. The aims of the project are to characterise human exposures to a range of air toxics emitted from consumer products (VOCs) and combustion sources (PM2.5, PAH, quinones and black carbon); and to find suitable biomarkers to monitor the exposure and effects to low-level of VOCs, especially benzene, and other air toxics using novel analytical and cutting-edge methodologies

From Airborne exposures to BiologicaL Effects (FABLE): the impact of nanoparticles on health funded by NERC/MRC Environment and Health. This linked programme of work begins with measurement and identification of metallic nanoparticles in the air, focusing on those from vehicle exhausts, manufacturing particles in the lab which have similar properties to ambient levels, using these in the lab to see how they enter cells and move within cells and then what effects these particles have on cellular function.  We will use real life doses which we will have obtained from our ambient measures.  Throughout the grant we will interact with policy makers in a range of Government departments and agencies so that these findings can influence policy development in nanoparticle exposure

SPADE Project: Sources and atmospheric Processes determining Airborne concentrations of polycyclic aromatic hydrocarbons and their DEgradation products funded by NERC. The major goals of this project are to study the rates and mechanisms of degradation of airborne PAH and to evaluate concentrations of their reaction products.

Health Implications of Polycyclic Aromatic Hydrocarbons in Indoor Environments funded by the National Institute for Health Research Central Commissioning Facility (NIHR-CCF). Research on the Health Effects of Outdoor and Indoor Air Pollution and Policy Research Programme. The aims of the project are to characterize PAH indoors and to compare whether indoor profile and carcinogenic potency are similar to those outdoors.

MATCH Project: Measurement and modelling of exposure to Air Toxic Concentrations for Health effect studies & verification by biomarker funded by the Health Effects Institute. The major goals of this project are to characterize exposures to VOC and PAH in personal, indoor and outdoor environments; to develop models to predict those exposures; to assess relationship between personal exposures and biomarker concentrations to VOCs and PAHs.
