It notes, however, that this probably undervalues the true amount of debris as many items, including those more than 10cm below the surface and dotted along cliff areas and rocky coastlines, could not be sampled.
"A lot of the items on Henderson Island are what we wrongly refer to as disposable or single-use", said Dr Jennifer Lavers from the University of Tasmania. Cigarette lighters, light bulbs, cutlery, tooth brushes, pen lids and plastic buoys were also found. Yet the desolate Pacific island is one of the densest hubs of plastic pollution on the planet.
For three months since May 2015, Lavers and colleagues lived on Henderson Island and documented all of the man-made trash there.
Henderson Island, which is part of the UK's Pitcairn Islands territory, sits right in the middle of the Pacific Gyre current, which makes it a "focal point" for garbage from South America as well as from fishing boats. Uninhabited for most of its history and only visited by scientists once a decade or so, Henderson Island should be completely untouched by humanity.
Island is located 5,000 kilometers west of Chine, and is one of the world's most remote and isolated.
Almost 27 percent of the items were identified of being from South America, which also included beach equipment and fishing gear.

United States accuses Syria of mass executions and burning the bodies
In February, Amnesty International said that mass hangings had taken place every week at the jail between 2011 and 2015. The complex is located just 45 minutes outside Syria's capital of Damascus, the seat of the Assad regime's power.
This is Henderson Island, a tiny, remote island in the South Pacific.
"Almost every island in the world and nearly every species in the ocean is now being shown to be impacted one way or another by our waste", she said.
Plastic debris is one of the most devastating polluters of the world's oceans, if only because there's so damn much of the stuff.
According to UNESCO, Henderson Island has 4 unique bird species and 10 unique plant species.
She said she sometimes found herself getting mesmerized by the variety and colors of the plastic that litters the island before the tragedy of it would sink in again.
Like seabirds and turtles, remote islands serve as sentinels for the health of the wider marine ecosystem, "acting like a sieve or a trap, filtering out the ocean", she said.
It means that by 2050, the plastic in the world's oceans will weigh more than all the fish, according to The Ellen MacArthur Foundation.
