1 Albuquerque, New Mexico Community Scale Ambient Air Monitoring and Risk Assessment By Fabian Macias Air Quality Assurance Program Manager Air Quality Division City of Albuquerque Mickey Leland National Urban Air Toxics Workshop II 1

2 Project Overview US EPA Air Toxics Grant Partnership Hazardous Air Pollutants Monitoring and Sampling Receptor Modeling Exposure and Risk Evaluation Status 2

3 US EPA Award Specifics About Half-Million Dollars Project Period 10/1/06 to 9/30/08 Quarterly Progress Reports Ambient Air Monitoring, Quality Assurance, Data Management and Results Availability Final Report 3

4 Partnership City of Albuquerque Air Quality Division Project Management, Quality Assurance Project Plan Development, Ambient Air Monitoring, US EPA AQS Data Management and Reporting, and Project Closure NMDOH Scientific Laboratory Division Sample Analyses and Reporting 4

5 Partnership continued Desert Research Institute Intense Monitoring, Data Assimilation, Atmospheric Modeling, Source Apportionment, Dispersion Modeling, Exposure Modeling to Hazardous Air Pollutants, and Risk Assessment 5

6 Ambient Air Sampling and Monitoring 6

7 Why Do We Monitor Ambient Air? Protect the public from elevated levels of air pollution. Identify and quantify what pollutants types are out there. To compare Albuquerque air quality to the National and State Standards. Preserve GOOD air quality. 7

8 What Do We Monitor In Ambient Air? Oxides of Nitrogen Carbon Monoxide Ozone Particulate Matter (PM 2.5, PM , PM10 ) Elemental and Organic Carbon Hazardous Air Pollutants PM2.5 Speciation Pollen Speciation Meteorological Conditions 8

18 Project Pollutants Volatile Organic Compounds Carbonyls Heavy Metals Polycyclic Aromatic Hydrocarbons Elemental Carbon/Organic Carbon 18

19 Hazardous Air Pollutants Sampling TO-11A DNPH Carbonyls HAPs TO-13A - PUF Semi-Volatiles HAPs TO-15 Canister Volatiles HAPs Metals Inductively Coupled Plasma Mass Spectrometry - Metal HAPs 19

20 Vertical Profiling 3 tethersondes (continuous measurements of WS, WD, T, Relative Humidity, Barometric Pressure), 3 tethered O 3 (Ozonesondes) (continuous measurements of ozone), a Nephelometer (TSI, Model 8520), ppb RAE plus (total VOCs measurements), & a tethered NO x sonde (NOx measurements). 20

21 Receptor Modeling DRI will use US EPA s Positive Matrix Factorization (PMF) to conduct a source apportionment study of particulate matter, aerosol characterization, and carbon analyses. DRI will use US EPA approved air transport and regional models to determine inter and intra-valley wind flow patterns. 21

22 Exposure and Risk Evaluation Use US EPA s HAPEM5 model to estimate personal exposure. Use the US Census Bureau for population demographics. Use US EPA s TRIM.expo module will be used to assess inhalation risks. Other risk assessment tools will be used to assess the risk of long-term exposure to HAPs. 22

23 Exposure and Risk Evaluation Use US EPA s TRIM.Risk module will be used to join the information on exposure with a dose-response module. Use of these tools will provide a first-order estimate of inhalation cancer risks and non-cancer hazard indices at both the individual and population level. 23

24 Project Status US EPA approved The Air Quality Division s Quality Assurance Project Plan Executed Inter-Governmental Cooperative Agreements with State of New Mexico and University of Nevada (DRI). In final approval stage. 24
