Plastic debris smaller than 5 mm, which is forrned as a result of physical and chemical 


of plastic waste, is defined as microplastic. Microplastics can be found in aquatic environments as 

primary and secondary sources. Primary microplastics occur as a result of conscious consumption of 

products containing microplastics produced in industries. Secondary microplastics, on the other 

hand, are forrned by the degradation of plastic wastes released into the aquatic environrnent or 

the environment over time. It is known that additives that can be harrnful to living things such as 

bisphenol A (BPA), heavy metals (such as lead, copper, cadrnium, ete.), phthalates are used in 

plastics in order to increase the strength and produce products with the desired properties. In 

addition, plastics are lipophilic and can adsorb and carry various pesticides and persistent 

organic pollutants (POPs) on their surfaces. When the environments in which microplastics are 

examined in recent years, the presence of microplastics in various marine habitats is mentioned. 

These can be listed as water column, sea sediments, deep sea regions, polar region and sea ice. 

When the coastal and gulf regions are evaluated, it has been revealed that the pollution status and 

the characterization of microplastics are at lower levels. Microplastics pose a great danger to the 

environment and health due to their properties such as containing additives, adsorbing toxic 

pollutants, being swallowed by living things as food, not being completely removed in wastewater 

treatment plants, being easily transported in the atmosphere and water resources, and being 

difficult to disappear in nature. Pollutions occurring in aquatic ecosystems also affect the 

sediment layer at the base of these structures. Although high­ density microplastics such as 

polyvinylchloride, polyester and polyamide accumulate in the sediments, the turbulence caused by 

the currents can cause these microplastics on the sea floor to be suspended and dispersed again 

along the water column. Therefore, in addition to detecting microplastics, removing them from these 

environrnents is an extremely important issue. When the studies are examined, it is seen that there 

is no standard procedure for the detection of microplastics. In addition, most of the studies 

discussed only focused on the detection methods of microplastics and there is no definitive method 

for removal methods, especially for the sediment environment. Within the scope of this study, it is 

aimed to investigate the microplastic removal methods in the sediment environment and to compare 

the suitability of the methods.
