The world is becoming increasingly aware of the dangers of the plastic that has become a ubiquitous part of the consumer world.
But while the plastic is often seen as an inexpensive and easy way to make something beautiful, it can also make for a toxic environment.
A study published in the journal Environmental Health Perspectives found that the particles floating in the ocean have a variety of potential health effects, including increased rates of heart disease and cancer.
“A lot of people say, ‘I don’t care about that stuff,’ ” said Dr. David M. Trenberth, a professor of preventive medicine at the University of Wisconsin, Milwaukee.
“But it is something that you should be aware of, especially when it comes to plastics.”
While the new study was limited to the United States, it is still an important finding.
The findings show that while there is no clear answer as to what causes marine plastics to turn into a toxic mass, the researchers believe it is likely linked to the oceanic currents that feed into the ocean.
A large number of the particles collected in the study, which was published online May 24 in the Journal of Environmental Science and Technology, were coming from different locations around the world.
The particles ranged in size from one to eight microns in diameter, with more than 90 percent coming from the ocean, according to the researchers.
“We found that these particles were coming primarily from the Gulf of Mexico and the Great Lakes,” said Trenkerth.
“There is no doubt that there is a direct connection between that and the concentration of plastics in the water.”
The researchers used data from the Environmental Protection Agency’s Marine Pollution Control Program (MPCP), which collects data on the number of tons of plastic in the United.
The program is part of a larger effort to better understand the effects of plastics on the environment.
MPCP collects data from fishing vessels, ships, oil tankers, and other sources, including in the Atlantic and Gulf of Alaska.
The organization is the only federal agency that can track the volume of plastic that is floating in oceans, and the amount of plastic floating in waterways.
According to Trencker, the PCBP data shows that the United Kingdom has the largest concentration of plastic particles in the sea.
The United States also has large concentrations of plastics, and Trenger said that many of the countries where these plastics are found have large populations of people living close to the coast.
The data also shows that these plastic particles are accumulating in places with very high concentrations of oceanic temperatures, such as in the Pacific.
“What we have found in the PCBs is that it’s not just coming from one place but also from many places,” said Michael M. Deutsch, a researcher at the Marine Pollutants Laboratory at Woods Hole Oceanographic Institution in Massachusetts, who was not involved in the research.
“It seems like the ocean is getting a lot of the plastics.”
Deutsch said that the researchers found a lot more plastics in places where the temperature is higher than it is in places that are warmer.
The PCBP website says that “the greatest concentration of ocean-pollutant pollution is found in waters with average temperatures above 32 degrees Fahrenheit and below 14 degrees Fahrenheit.”
The study also found that more than a third of the marine plastics collected in each location had high concentrations.
“In terms of size, they were about the same size as the average piece of plastic,” said M.J. Hagen, a postdoctoral researcher at UMass Amherst and the lead author of the study.
“They are not particularly big.
They’re smaller than a penny.
But they’re pretty big.”
The particles are mostly made of polyvinyl chloride, a plastic that can be used to make toys, shoes, and more.
“Polyvinyl acetate is one of the most common plastics,” Trenner said.
“The polymer is made of two types of polymers that are both made up of two carbon atoms, but each carbon atom has one electron.
This makes the polymer very flexible.”
It is also one of several types of plastics that can become unstable in the presence of heat and pressure.
According the Environmental Defense Fund, plastics are one of 10 common household chemicals that are responsible for more than 5,000 deaths a year worldwide.
In the United Sates, plastic is used in everything from tires and clothing to paper products and paint.
“I think there are a lot less things people are aware of that are associated with plastic pollution than there are with lead and cadmium,” T.J., a 30-year-old graphic designer in California, said.
But, as with lead, the plastic industry doesn’t have to rely on science to protect its products.
In fact, plastics, like the ones used in the new paper, have become the focus of a heated debate in the past.
“Most people are unaware that there are toxic
