LAS VEGAS—Wherever you travel in the West, one thing is clear—or perhaps unclear. It’s haze, and it’s a growing problem. But it’s not limited to cities anymore. Even in wilderness areas or natural wonders like the Grand Canyon, visibility is often marred by reduced air quality.

What’s causing the problem? Dr. David DuBois, an assistant research air quality scientist at the Desert Research Institute, wants to know. At the monthly meeting of the Las Vegas chapter of the Air &Waste Management Association, at noon on Wednesday, March 10, at the Tuscany Suites Hotel and Casino, DuBois will talk about his work as part of the “Causes of Haze Assessment” project.

COHA, as the project is called, is a coordinated regional effort to answer nagging questions about haze:

-- What are its chemical components?
-- What are the relationships between haze and weather?
-- What role do emissions play in causing haze?
-- Can emission reductions lead to improved visibility?

The Western Regional Air Partnership and the Central Region Air Planning Association fund COHA, which is focused on examining the causes of haze in areas west of the Mississippi River including Alaska and Hawaii. More than 150 sites are represented in this ongoing research study.

For his part, DuBois is looking at what is causing haze in national parks or wilderness areas and how to reduce it. Prior to joining DRI, DuBois was an environmental engineering scientist and manager with the New Mexico Environment Department's Air Quality Bureau, in Santa Fe. He has done extensive research in atmospheric chemistry and modeling the dispersion of air pollutants.

Registration for the talk at AWMA’s meeting will begin at 11 a.m. Lunch will be served at 11:30. DuBois’ talk will begin at noon. Lunch with reservations is $20 for AWMA members and $25 for non-members. Full-time students are $10.

For reservations or more information, contact Brian McQuown at 702-407-4861 or bmcquown@reliant.com.

Tuscany Suites Hotel and Casino is at 255 East Flamingo Road, east of Koval Lane.
