Air Pollution

Killer air


Globally, air pollution kills 3.3 million people per year. And this number could double to 6.6 million people by 2050 if little is done to decrease the dangerous levels of tiny particles, toxins, and ozone in the air.

The problem with coal ash


Coal combustion in the U.S. generates around 130 million tons of coal ash each year, with power plants being the largest contributors. Bottom ash is collected from combustion chambers and fly ash is gathered from smokestacks and air pollution control devices.

Summertime ozone


Human activities are not direct sources of a lot of ozone, but ozone concentrations increase to markedly unhealthy levels in many areas during the summer. About 30 years ago, atmospheric chemists solved this mystery.

Mist Connections: A Tale of Fog and Forests

Lecture Video

A world-renowned expert, Kathleen Weathers talks about how fog interacts with air, land and water, and investigates its importance to ecosystems.

Let's talk about ammonia


Most of us are familiar with ammonia as an irritating gas that is emitted from window-cleaning fluids. It is a great way to cut through grease that has condensed on glass.

A New View of Adirondack Lakes


A film about the sampling of water from 520 lakes in the Adirondack Park, filmed from an AirCam on floats in HD over three summers.


An Ill Wind

Conservation Magazine reports on a study by Dr. Kathie Weathers and colleagues on how polluted streams contribute to airborne bacteria.


We all know about rain forests. Now we are learning about fog forests


There's a desert in north-central Chile that receives less than six inches of rain a year. Right in the middle of it is a lush mountain forest that is dense with trees, bromeliads, ferns, and mosses.

Limiting emissions key to clean air

There are three major air pollutants in Dutchess County: ozone, particulate matter, and acid precipitation.

New rule tackles air pollution

We ecologists take a lot of flack for always having depressing news to report. It's not often we get to say there is good news on the environmental front, but those of us concerned with air pollution have certainly had reasons to smile this summer.

Clean air, water didn't sink economy

Several members of Congress and presidential hopefuls have proposed rolling back the Environmental Protection Agency's authority to regulate with the Clean Air and Clean Water acts as a solution to our woes.


Data show ozone turnaround

There was some good news on the environment last week. In the 20-state area that participates in a cap-and-trade program to reduce emissions of nitric oxide (NOx) from power plants, the emissions declined 32 percent from 1997 to 2005.

Curbing mercury emissions is crucial

The Mad Hatter in "Alice in Wonderland" plays an important role in the history of occupational health and safety.

Why you should care about ozone warnings

From Beijing to Beacon, air pollution alerts are rampant this summer. One of the primary causes for these alerts is high levels of "bad" ozone.

Airborne pollutants harm diverse habitats

If you are living in the eastern United States, the environment around you is being harmed by air pollution.

Notes from the field: Environmental monitoring- Who needs it?

I have spent many years unraveling how invasive species and air pollution influence forest ecosystems. This research has taken me deep within New York’s Catskill Forest and New Hampshire’s White Mountains—places of amazing natural beauty. Lately, however, I’ve found myself pounding the pavement in Washington, D.C.
