Microplastics occurrence in sea cucumbers and impacts on sea cucumbers & human health: A systematic review
Summary
This systematic review found that microplastics are ubiquitous in sea cucumber ecosystems, with high concentrations in coastal sediments where these deposit feeders live. Some studies report that microplastic ingestion reduces sea cucumber feeding efficiency, alters behavior, and causes tissue damage, raising concerns for both ecosystem health and human consumers of this seafood.
Microplastics (MPs) are a developing concern in marine environments, with scientists concentrating more on their effects on various creatures. Sea cucumbers (SCs), as suspension and deposit feeders, are expected to be exposed to and consume MPs in their habitat. The purpose of this methodical review is to gather and integrate accessible research on the presence and effects of MPs on SCs. A systematic search of relevant databases yielded relevant papers exploring the occurrence of MPs in SC habitats as well as the possible effects of MP intake on SCs. Bibliometric analysis was also conducted to collect and analyze a large volume of data. Then the papers were sorted (a total of 249) related to the occurrence and effects of MPs in SCs. Finally, targeted data were collected from the articles for the study. The review emphasizes the ubiquity of MPs in SC ecosystems, citing studies that found high quantities in coastal areas and sediment. MPs have a variety of effects on SCs, with some studies indicating that they lower eating efficiency, affect behavior, and cause tissue damage. However, there is still no unanimity on the overall effects of MP exposure on SCs. This review gives a complete summary of the present state of information about the incidence and impact of MPs on SCs, highlighting the need for additional study in this area. Understanding the possible dangers of MPs on SCs is critical for the survival of these ecologically significant creatures.

Existence of microplastics in the edible part of the sea cucumber Apostichopus japonicus
Researchers demonstrated that microplastics can transfer into the edible body wall of sea cucumbers (Apostichopus japonicus), entering through the outer surface and potentially posing a threat to human health through seafood consumption.
Plastic litter transfer from sediments towards marine trophic webs: A case study on holothurians
Sea cucumbers collected from the seafloor around a Sicilian island were found to contain microplastics in their bodies, having ingested them while feeding on sediment. Since sea cucumbers are consumed as food in many cultures, this represents a direct pathway for microplastic exposure in humans.
Types and Abundance of Microplastics in the Digestive Tract of Cucumbers in Banyak Island, Aceh Singkil
Researchers examined the digestive tracts of sea cucumbers from Banyak Island, Indonesia, identifying microplastic types and quantities ingested by these organisms in a coastal area affected by community plastic waste.
Preliminary study of microplastics content in the digestive tract of sea cucumber from Demak Waters
Sea cucumbers collected from Demak Waters, Indonesia, were found to contain microplastics in their digestive tracts. Since sea cucumbers are eaten raw in many cultures, this finding raises direct concerns about human microplastic exposure through seafood consumption.
Potential harmful impacts of micro- and nanoplastics on the health of a tropical sea cucumber, Holothuria leucospilota, evidenced by changes of gut microflora, histology, immune and oxidative indexes
Scientists exposed tropical sea cucumbers to both nano-sized and micro-sized plastic particles and found that both caused gut damage, altered the gut microbiome, triggered oxidative stress, and disrupted immune function. Notably, the smaller nanoplastics had stronger effects than the larger microplastics, and plastic particles were observed accumulating in the gut tissue.
