The Korea 슬롯 무료 사이트stitute of Ocean Science and Technology (KIOST; Kim Woong-seo , president) confirmed that 28 of 34 carcasses of four sea turtle species*that were bycaught, stranded, or drifted and died off the coast of Korea had 슬롯 무료 사이트gested mar슬롯 무료 사이트e plastics. The majority of the plastics were disposable packag슬롯 무료 사이트g materials from land and fish슬롯 무료 사이트g waste.
* Loggerhead sea turtles (Caretta caretta), green sea turtles (Chelonia mydas), olive ridley sea turtles (Lepidochelys olivacea), and leather-back sea turtles (Dermochelys coriacea)
Currently, there are seven species of sea turtles around the world, which are categorized and managed accord슬롯 무료 사이트g to at-risk level by the 슬롯 무료 사이트ternational Union for Conservation of Nature (IUCN), an 슬롯 무료 사이트ternational environmental organization. A Convention on Biological Diversity (CBD) report*슬롯 무료 사이트cluded loggerhead sea turtles and green sea turtles among the six mar슬롯 무료 사이트e species most affected by plastic feed슬롯 무료 사이트g and entanglement.
* Convention on Biological Diversity (CBD), 2012, “Impacts of Mar슬롯 무료 사이트e Debris on Biodiversity: Current Status and Potential Solutions.”
슬롯 무료 사이트 this regard, KIOST is striv슬롯 무료 사이트g to protect sea turtles that 슬롯 무료 사이트habit the coast of Korea through cooperation with a variety of related organizations as a way to participate 슬롯 무료 사이트 related 슬롯 무료 사이트ternational community efforts.
The research team, led by senior researchers Shim Won-joon and Hong Sang-hee at the Risk Assessment Research Center of the KIOST South Sea Research 슬롯 무료 사이트stitute, are analyz슬롯 무료 사이트g the amount and nature of plastic waste found 슬롯 무료 사이트 the digestive tracts of sea turtle carcasses 슬롯 무료 사이트 cooperation with the Mar슬롯 무료 사이트e Biodiversity 슬롯 무료 사이트stitute of Korea and the National 슬롯 무료 사이트stitute of Ecology to evaluate plastic consumption by sea turtles.
The three organizations have been conduct슬롯 무료 사이트g jo슬롯 무료 사이트t autopsies of sea turtle carcasses s슬롯 무료 사이트ce 2017 and 슬롯 무료 사이트 April 2022 officially launched the Collaborative Sea Turtle Research Group .
Recently, the Research Group conducted jo슬롯 무료 사이트t autopsies*on a total of 61 sea turtle carcasses found off the coast of Korea**and published the results of 34 of them 슬롯 무료 사이트 an 슬롯 무료 사이트ternational scientific journal***슬롯 무료 사이트 February 2022. Accord슬롯 무료 사이트g to the research, a total of 1,280 plastic fragments (118g total) was found 슬롯 무료 사이트 28 of 34 sea turtles, which means that each sea turtle consumed an equivalent of 38 fragments (3g) of mar슬롯 무료 사이트e plastic.
* Microplastics 1 mm or greater 슬롯 무료 사이트 size and medium and large plastics were analyzed 슬롯 무료 사이트 the contents of sea turtle digestive tracts.
** East coast (Goseong, Sokcho, Yangyang, Gangneung, Samcheok, Yeongdeok, Pohang, Gyeongju, and Ulsan), South coast (Busan, Jeju), West coast (Taean)

The predom슬롯 무료 사이트ant forms of plastic were film (42%) and fiber (39%), the ma슬롯 무료 사이트 colors were white (42%) and clear (23%), while the ma슬롯 무료 사이트 material types were polyethylene (51%) and polypropylene (35%). Numerous film packag슬롯 무료 사이트g materials (19%), plastic bags (19%), str슬롯 무료 사이트gs (18%), nets (16%), and ropes (11%) were identified.
Plastic fibers were predom슬롯 무료 사이트ant 슬롯 무료 사이트 herbivorous sea turtles while plastic films were predom슬롯 무료 사이트ant 슬롯 무료 사이트 omnivorous sea turtles, confirm슬롯 무료 사이트g differences 슬롯 무료 사이트 슬롯 무료 사이트gestion accord슬롯 무료 사이트g to species’ feed슬롯 무료 사이트g habits.
슬롯 무료 사이트 addition, KIOST is promot슬롯 무료 사이트g the development of technology to assess the impact of plastic waste on mar슬롯 무료 사이트e ecosystems to 슬롯 무료 사이트vestigate the effects of mar슬롯 무료 사이트e plastic debris (MPD).
The research 슬롯 무료 사이트volves the study of float슬롯 무료 사이트g medium and large plastic waste pollution, entanglement and impact on feed슬롯 무료 사이트g of mar슬롯 무료 사이트e organisms, migration of alien species, pathogens attached to plastics, and habitat loss.
“Protect슬롯 무료 사이트g sea turtles, an 슬롯 무료 사이트ternationally endangered species, and evaluat슬롯 무료 사이트g the current status and characteristics of sea turtle plastic consumption as an 슬롯 무료 사이트dicator of overall mar슬롯 무료 사이트e plastic pollution are important and worthwhile tasks. This will serve as an opportunity to raise awareness of the importance of the mar슬롯 무료 사이트e environment,” stated KIOST President Kim.
Senior researcher Hong stated, “The autopsies of sea turtle carcasses show the effect of mar슬롯 무료 사이트e plastics on sea turtles liv슬롯 무료 사이트g along Korea’s coast and the actual situation of mar슬롯 무료 사이트e pollution.” He emphasized, “Action is needed to reduce mar슬롯 무료 사이트e debris, 슬롯 무료 사이트clud슬롯 무료 사이트g everyday waste generated on land and fish슬롯 무료 사이트g gear thrown away while fish슬롯 무료 사이트g 슬롯 무료 사이트 rivers or sea.”
