Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Eighty percent of marine debris is plastic. [1] [2] Microplastics and nanoplastics result from the breakdown or photodegradation of plastic waste in surface waters, rivers or oceans. Recently, scientists have uncovered nanoplastics in heavy snow, more ...
Marine debris, also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or the ocean. Floating oceanic debris tends to accumulate at the center of gyres and on coastlines , frequently washing aground, when it is known as beach litter or tidewrack.
Plastic pollution puts animals' lives in danger and is in constant fear of extinction. Marine wildlife such as seabirds, whales, fish and turtles mistake plastic waste for prey; most then die of starvation as their stomachs become filled with plastic. They also suffer from lacerations, infections, reduced ability to swim, and internal injuries ...
In addition to all these impacts, the marine debris and beach litter pose dangers to wildlife on the beaches and marine ecology. [20] Many beach pollutants such as fishing gears and nets or oil spills jeopardize many sea animals including sea turtles , seabirds, and dolphins , and can cause serious injuries or death. [ 16 ]
The editorial board of the journal is composed of experts in the field of marine pollution, who review and select articles for publication based on their scientific merit and relevance to the journal's scope. [4] According to the Journal Citation Reports, the journal has a 2021 impact factor of 7.001. [5]
Plastic pellet pollution is a type of marine debris originating from the plastic particles that are universally used to manufacture large-scale plastics. In the context of plastic pollution , these pre-production plastic pellets are commonly known as ' nurdles' . [ 1 ]
Similarly, fishing debris has been shown to be a major source of plastic debris found on the shores of Korea. [50] Marine life interacts with debris in two ways: either through entanglement (where debris entangles or entraps animals), or ingestion of the debris (either intentionally or accidentally). [51] Both are harmful to the animal. [51]
Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Plastic pollution is harmful to marine life. Another concern is the runoff of nutrients (nitrogen and phosphorus) from intensive agriculture, and the disposal of untreated or partially treated sewage to rivers and subsequently oceans.
