Ambient Air Sampling and Monitoring



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.



8

What Do We Monitor In Ambient Air?

• Oxides of Nitrogen

• Carbon Monoxide

• Ozone

• Particulate Matter (PM2.5, PM10-2.5, PM10)

• Elemental and Organic Carbon

• Hazardous Air Pollutants

• PM2.5 Speciation

• Pollen Speciation

• Meteorological Conditions

Project Pollutants

• Volatile Organic Compounds

• Carbonyls

• Heavy Metals

• Polycyclic Aromatic Hydrocarbons

• Elemental Carbon/Organic Carbon



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



20

Vertical Profiling

• 3 tethersondes (continuous measurements of WS, WD, T, Relative Humidity, Barometric Pressure),

• 3 tethered O3 (Ozonesondes) (continuous measurements of ozone),

• a Nephelometer (TSI, Model 8520), • ppb RAE plus (total VOCs measurements), &

• a tethered NOxsonde (NOx measurements).



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.



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.



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.



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.



25

Challenges

• Project Analysis and Reporting • Community Outreach Plan

– Data Dissemination– Presentations to Stakeholders

• What do policy and decision makers do with this information?

• Other Partnerships• Continued Funding
