1. Project EDDIE: Distribution and Fate of Volatile Organic Contaminants (VOCs)Federico Sinche
2. Air Pollutants US EPA Criteria Pollutants are regulated through human health-based and environmental criteria.
3. Air Pollutants: VOCs Volatile organic compounds (VOCs) are carbon-based compounds that participate in atmospheric photochemical reactions. VOCs can be applied to both indoor and outdoor air quality.*VOCs do not include particulate matter, CO, CO2, H2CO3, (NH4)2CO3, CO2-3
4. Air Pollutants: VOCs characteristics VOCs can be classified by their volatility and boiling point. The higher the volatility (lower the boiling point), the more likely the compound will be emitted from a product or surface into the air. *WHO: World Health Organization
5. Sources of VOCs
6. Health effects from exposures to VOCs
7. Air Pollution Monitoring

9. National Air Pollution Monitoring For Activities A and B of the module, the following datasets will be provided by the students by the instructor:“Illinois_VOCs_2010”“Illinois_VOCs_2020”For Activity C of the module, the following datasets can be downloaded from the US EPA website:https://aqs.epa.gov/aqsweb/airdata/download_files.html#Annual The annual data on VOCs can be found under “Toxics, Precursors, and Lead”
10. National Air Pollution Monitoring This is how the datasets from the US EPA looks like:Datasets organized by year. Choose 2020.Types of air pollutants. Choose VOCs.
11. National Air Pollution Monitoring Datasets organized by year. Choose 2010.
12. The three types of VOCs for this module
13. VOC: FormaldehydeChemical Structure Characteristics: colorless gas with a pungent, suffocating odor at room temperature. Acute health effects: eye, nose, and throat irritation and effects on the nasal cavity.Chronic health effects: EPA considers formaldehyde to be a probable human carcinogen and has ranked it in EPA’s Group B1.
14. VOC: Formaldehyde Sources of formaldehyde in the air: Manufacturing of urea-formaldehyde resins, used in particleboard products Released from building materials and home furnishings Emissions from power plants, manufacturing facilities, incinerators, and automobile exhaust.Urea-formaldehyde product
15. VOC: Formaldehyde Concentrations of formaldehyde in urban areas reported ranging from 0.000011 to 0.000020 ppmNational Institute of Occupational Safety and Health (NIOSH) recommended exposure limit for an 8- or 10-h time-weighted-average exposure and/or ceiling
16. VOC: Benzene Chemical Structure Characteristics: is a colorless liquid with a sweet odor. This highly flammable liquid dissolves in water. Acute health effects: headaches, respiratory tract irritation, drowsiness. Chronic health effects: disorders in the blood (aplastic anemia, leukemia). It is characterized as a known human carcinogen.
17. VOC: Benzene Sources of benzene in the air: Emissions from burning coal and oilMotor vehicle exhaust Smoking Evaporation from gasoline service stations Byproduct from industrial solvents
18. VOC: Benzene The American Industrial Hygiene Association’s detection and recognition odor thresholds for benzene are 61 ppm and 97 ppm, respectively National Institute of Occupational Safety and Health (NIOSH) recommended exposure limit for an 8- or 10-h time weighted-average and/or ceiling
19. VOC: Acrolein Chemical Structure Characteristics: is a clear or yellow liquid with a burned, sweet, and pungent odor. Acute health effects: eye irritation, nose/throat irritation, decrease in respiratory rate. Chronic health effects: strong dermal irritant, prolonged respiratory congestion and eye, nose, and throat irritation.
20. VOC: AcroleinSources of acrolein in the air: Acrolein is primarily used as an intermediate in the synthesis of acrylic acid and as a biocideVapors from overheated cooking oil or grease Smoking tobaccoVehicle exhaust, oil- and coal-fired power plants
21. VOC: AcroleinThe Agency for Toxic Substances and Disease Registry (ATSDR) has established an acute minimal reference level of 0.003 ppmNational Institute of Occupational Safety and Health (NIOSH) recommended exposure limit for an 8- or 10-h time-weighted-average exposure and/or ceiling
