Lecture: Dr. Ben Wheeler Sept. 26, 2018 Exposure pathways Source activities (e.g. presence of a factory that releases benzene) Emissions to: Air Land Water Environmental Population: Concentrations Residence and Activities Individual External Exposure Individual Internal Dose Organ/Cell level dose How are people exposed to the environment? Exposures Chemicals, radiation, microbes, noise, weather conditions, greenspace, aesthetics These will be impacted by LOCATION (outside, inside the home), MEDIA (air, water, land), RECEPTOR (physiology, psychology, senses), or TIMING (past, current, future, acute—chronic) Can our exposure assessment fully capture this complexity? Probably will get it a bit wrong, but try to get it as close as possible How do we estimate exposure? Experimental Intervene—chamber studies, virtual environments, directed/escorted visit activities Realistic vs. env exposure—not in usual circumstances?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
