Cancer Plagues California Sea Lions, With Implications for Humans

A virus-linked cancer killing California sea lions is sounding a chilling alarm for mankind.

Exposure to environmental toxins significantly boosts risk for the herpes-like cancer, which was discovered in sea lions in 1979.

Since then, between 18% and 23% of adult sea lions admitted to a California animal rescue-and-research center have died of the disease. That's the highest rate f...

Which Seafood Has the Highest Amount of Microplastics?

Those mussels, oysters and scallops on your plate may come with a secret ingredient: microplastics.

Researchers at Hull York Medical School and the University of Hull in the United Kingdom reviewed more than 50 studies (from 2014 to 2020) to investigate the levels of microplastic contamination globally in fish and shellfish.

The investigators found that mollusks (such as clams, muss...

Autopsies Show Microplastics in All Major Human Organs

Microscopic bits of plastic have most likely taken up residence in all of the major filtering organs in your body, a new lab study suggests.

Researchers found evidence of plastic contamination in tissue samples taken from the lungs, liver, spleen and kidneys of donated human cadavers.

"We have detected these chemicals of plastics in every single organ that we have investigat...

Wildfire Pollution Puts Kidney Patients at Risk

Air pollution caused by forest fires can be deadly for people with kidney failure, a new study suggests.

The tiny particles of air pollutants -- called fine particulate matter -- from wildfires can trigger inflammation in the lungs and further affect the delicate health of people with kidney failure, the researchers said.

Using data from the U.S. Renal Data System (a regis...

Summer's Toxic Algae Blooms: A Growing Threat to Health?

Every summer seems to bring fresh warnings of toxic algae blooming in local ponds, lakes and waterways.

These toxic blooms are known to be dangerous to human and animal health, but a new study suggests they might be even more harmful than previously thought.

A single massive blue-green algae bloom in Florida's Lake Okeechobee and the Caloosahatchee River flowed into the Gulf...

Will COVID Pandemic's Environmental Benefit Last?

It has been the sole silver lining in the coronavirus pandemic -- cleaner air and water on the planet. But will it continue?

A new study says that isn't yet clear.

"The pandemic raises two important questions related to the environment," said study author Christopher Knittel, from the MIT Sloan School of Management in Boston. "First, what is the short-run impact on fossil fu...

Don't Get Sick While Swimming This Summer

Swimming and summer are practically synonymous, but getting sick from bacteria in lakes, rivers and the ocean can spoil the fun, U.S. health officials warn.

Since 2009, nearly 120 disease outbreaks in 31 states have been tied to untreated recreational water. But being aware of potential harms and taking precautions can help keep you healthy while you cool off, according to a new repor...

During Droughts, Many Poor Americans Will Lack Clean Tap Water: Study

Poor and minority Americans are most likely to lose access to clean tap water as droughts become more common and severe, a new paper says.

Water service in the United States is delivered by tens of thousands of community systems, most of which are small and funded locally, according to the study.

More than 80% of the 50,000-plus U.S. community water systems delivering wa...

Plastic Smells Like Lunch to Sea Turtles, Putting Them at Risk: Study

Sea turtles mistake the smell of stinky plastic for food, researchers say.

Sea turtles worldwide are threatened by marine plastic debris, mostly due to eating it and getting tangled in it, noted the authors of the study published March 9 in the journal Current Biology.

"We found that loggerhead sea turtles respond to odors from biofouled plastics in the same way they ...

Even Dolphins Are Threatened by Antibiotic-Resistant 'Superbugs'

Scientists have found one more way Flipper is a lot like people: The sharp rise in antibiotic resistance affecting humans is also happening to dolphins.

The discovery stems from a 13-year study of bottlenose dolphins in Florida's Indian River Lagoon.

"We've been able to provide a large database of information in order to continue learning from these impressive animals," sai...

Diving Deeper Into Sunscreen's Impact on Marine Life

Is the sunscreen you slather on your body marketed as safe for coral reefs? New research suggests those claims may not be entirely true.

Trace metals and other compounds in many sunscreens have unknown effects on marine ecology, say researchers studying Mediterranean waters.

Previous studies have shown that ultraviolet-screening ingredients in sunscreens can harm coral and o...

50 Years After Ban, Canadian Lakes Still Have High Levels of DDT

Although DDT was banned in the 1970s, the toxic pesticide still lurks in the sediment of lakes in New Brunswick, Canada, researchers report.

To control insects, airplanes sprayed nearly 6,300 tons of DDT onto New Brunswick forests between 1952 and 1968.

Sprayed DDT can enter lakes and rivers, and find its way into the food chain, researchers say.

To see if DDT had ...

Your Drinking Water May Harbor Cancer-Causing Nitrate: Study

Millions of tons of nitrate from industrial farming find their way into America's drinking water each year, causing thousands of cases of cancer and other health problems, an environmental advocacy group says.

In a new report, researchers from the Environmental Working Group (EWG) quantify the risk. They say nitrate is responsible for nearly 12,600 cases of cancer a year.

Antibiotics Pollute Rivers Worldwide: Study

Levels of antibiotics in some of the world's rivers are hundreds of times higher than what's considered safe, British researchers report.

For the new study, investigators checked rivers in 72 countries on six continents for 14 widely used antibiotics and found them at 65% of monitored sites.

"The results are quite eye-opening and worrying, demonstrating the widespread co...

Well Water's Spillover Effect: Heart Damage?

Does your home draw its water source from a well? A new study finds that well water may be injurious to heart health in young adults -- if it contains arsenic.

"People drinking water from private wells, which are not regulated, need to be aware that arsenic may increase the risk for cardiovascular disease," said study author Dr. Gernot Pichler. He is an internal medicine specialist at...

Agent Orange's Toxic Legacy in Vietnam

A toxic byproduct of Agent Orange is still widespread in Vietnam's soil and water and is getting into food supplies, a new study claims.

Agent Orange was a chemical defoliant widely used by the U.S. military during the Vietnam War from 1962 to 1975. The herbicide contained dangerous dioxins.

"Existing Agent Orange and dioxin research is primarily medical in nature, focusing ...

The Deadliest Plastic for Seabirds? Balloons

No plastic is good for seabirds, but new Australian research finds that balloon bits pose the most deadly threat to marine life.

"Balloons, or balloon fragments, were the marine debris most likely to cause mortality, and they killed almost one in five of the seabirds that ingested them," said study author Lauren Roman, a Ph.D. student at the University of Tasmania's Institute for Mari...

'Microplastics'  in Dolphins, Seals Heighten Environmental Concerns

In a microcosm of the planet's ocean woes, British researchers report that 50 dolphins, seals and whales examined after washing up on that country's shores all had pieces of discarded plastic trapped in their digestive tracts.

More than 80 percent of the tiny pieces were synthetic fibers from items such as discarded clothes, fishing nets and toothbrushes, according to researchers from...

Climate Change Already Hurting Human Health, Review Shows

Climate change is already having clear effects on human health, according to a new review that describes the situation as a "health emergency."

"Climate change is causing injuries, illnesses and deaths now from heat waves, infectious diseases, food and water insecurity, and changes in air quality, among other adverse health outcomes," said Kristie Ebi, one of the report's authors.
