Air Pollution and Exposure Assessment
Exposure to airborne particulate matter (PM) has been shown to consistently correlate with pulmonary and cardiovascular disease.

In this annual fall event school groups all along the Hudson River estuary go down to the river's edge to collect scientific information and share it to creat
A monitoring program was initiated in 2001 to monitor the Hudson River's basic state variables of salinity, temperature and density along transects from New York Harbor to Troy.

Interns developed skills in science communication by creating educational materials about the river’s colorful stories, myths, and misunderstandings.
In a summer program, students learned about and discussed the science of the Hudson River watershed, as well as the social issues present in their daily lives.
A student group examined the types of microplastics entering the river, and created a way for citizen scientists to help with the research.
The newly renovated research facility will host an educational mural that combines art and science.
Join us on Saturday, June 1st to explore one of New York’s most underrated treasures: our productive waterways!
A new study shows that fecal bacteria from sewage can persist in far greater quantities in near-shore sediments than in the water of the Hudson River.
In a new study, researchers have mapped out a large variety of discarded pharmaceuticals dissolved throughout the Hudson River. They say that in some places, levels may be high enough to potentially affect aquatic life.
Plastic microbeads, common in soap, toothpaste and other consumer products, are flooding waters. A team from Lamont-Doherty Earth Observatory is doing the first large-scale assessment of their impact on New York’s waterways.
Lamont's Andy Juhl and a team of scientists working with the non-profit Riverkeeper conducted an unprecedented health check of the entire Hudson River system, starting at the headwaters high in the Adirondacks and going all the way to New York Harbor, where the river meets the ocean. They released their results today, giving the 315-mile-long Hudson River a spotty but mostly positive health report with some important insights.
The risk of catching some nasty germ in the Hudson River just started looking nastier. Disease-causing microbes have long been found swimming there, but now researchers have documented antibiotic-resistant strains in specific spots, from the Tappan Zee Bridge to lower Manhattan. The microbes identified are resistant to ampicillin and tetracycline, drugs commonly used to treat ear infections, pneumonia, salmonella and other ailments. The study is published in the current issue of the Journal of Water and Health.
Water is on the minds of Rockland residents this summer, and not just because of the record U.S. drought. Rockland County’s main water provider, United Water NY, wants to build a treatment plant on the Hudson River that would deliver more freshwater to Rockland taps. Some people are in favor of boosting supply to this growing suburban region, a short drive from the George Washington and Tappan Zee bridges. Others are opposed, citing the cost, in energy and dollars, plus the danger to fish and other wildlife. As the project awaits approval from the state Department of Environmental Conservation, a new debate on water consumption has emerged. Should people be encouraged, or even required, to use less? And if so, how?
The Hudson River that explorer Henry Hudson sailed some 400 years ago had no power plants on its shores. No trains, bridges, factories or houses. Those innovations changed the river, leaving a legacy of PCBs, sewage and other pollutants. But pollution is just one way that humans have transformed the river. A small way, it turns out.
People are swimming in the Hudson again, and while clumps of sewage rarely float by anymore, the water is not reliably clean, says a report released this week from the environmental group Riverkeeper.
Another world lies beneath the Hudson River, as scientists have shown using pulses of sound to map the bottom. In recent years, the bathymetry maps developed at Lamont-Doherty Earth Observatory and Stony Brook University have turned up hundreds of shipwrecks and a new channel off Battery Park City, drawing interest from treasure hunters and mariners alike. Now a new group is finding inspiration: artists.
Ongoing Work By Scientists Will Supply Data to the Public
A frequently asked question around New York is: “Is it safe to swim? This has spurred Columbia University’s Lamont-Doherty Earth Observatory...
The Hudson River Estuary, a stretch of the Hudson River from Troy, N.Y. to its mouth in New York Harbor, has begun a new stage of its life say geologists at Columbia University's Lamont-Doherty Earth Observatory and Queens College in Flushing, N.Y. Researchers at both institutions have found that, aside from a few very specific locations, the estuary may have largely stopped filling in with new sediment.
