Exposure science examines the ways in which individuals encounter and are exposed to physical, chemical, biological and other stressors in both general environments and workplaces. Within epidemiology, exposure assessment is crucial to identify specific exposure agents and determine their impact on mortality/morbidity across varying populations—be it a community, city, state or country.
The Human Exposure Assessment Lab (HEAL) is dedicated to precisely measuring the exposure of populations to both chemical and non-chemical stressors across time and space, as well as discerning the subsequent effects on health. Furthermore, HEAL is committed to devising and enacting evidence-driven interventions aimed at mitigating these exposures, particularly among at-risk populations in Philadelphia, the US and beyond.
The ELSA study is a community-engaged project to characterize individual, work-related and neighborhood-level determinants of longitudinally-measured total personal air exposure to a suite of volatile organic compounds (VOCs) among an overburdened group of Hispanic women in San Antonio, Texas, and to understand the impact of these exposures on biomarkers of early respiratory health effects. The ELSA team is born from a collaboration between multi-disciplinary researchers at the Temple University, UTHealth School of Public Health, Baylor College of Medicine, and the University of Texas Health Science Center at San Antonio.
Project period: 3/1/2021–12/31/2024
The objective of the MALDA study is to develop a full-function Mobile Aerosol Lung Deposition Apparatus (fMALDA) and apply fMALDA for correctly estimating the ultrafine particles (UFP) respiratory deposition and associated inhalation dosimetry in urban communities with various toxic chemical constituents. Ambient air size-fractionated polycyclic aromatic hydrocarbons and transitional metals will be characterized for the inhalation dosimetry. This project is co-led by the Temple HEAL and UTHealth.
Project period: 4/1/2020–3/31/2023
The CAMP study investigates the presence of airborne microplastics and nanoplastics in Philadelphia, aiming to pinpoint potential urban sources of these particles across diverse neighborhoods. This innovative research employs a combination of intensive on-site environmental sampling, state-of-the-art analytical techniques, and geospatial data interpretation. Through this, HEAL aims to characterize the forms, varieties, and levels of microplastics and nanoplastics present in the atmosphere.
Project period: 6/18/2023–5/31/2025
