“…[25] reported that the microplastic abundance in Xisha Islands's corals was 20-1300 particles kg -1 . The different investigations by Oldenburg et al [26] reported that the abundance of microplastics in Sapodilla Cayes (296±SE 89 particles kg -1 ) and Drowned Cayes (75±SE 14 particles kg -1 ).…”

“…Nonetheless, no efforts were made to widely study the fate and distribution of microplastics in corals. To date, only limited publications were reported on the occurrence and distribution of microplastics on corals [25,26,32]. This study explores the influence of reef architectural forms on microplastics by comparing the relative abundance, size, and shape of microplastics on four coral life-forms represented by four different coral species namely massive (Porites lutea), submassive (Galaxea fascicularis), folious (Montipora foliosa) and branching corals (Acropora aspera) (Fig.…”

“…Polyp number was recorded. Corals were then decalcified with a 1.0% HCl solution for 12 h (Rotjan et al, 2019), filtered using a glass-fiber membrane of 0.45 µm, and then back washed into a sterile glass vial (Rotjan et al, 2019;Oldenburg et al, 2021). After that, 150 ml NaOH (10%, V/V) was added to the vial to digest any organic tissue residue, and then the vials were placed in a 60 • C drying oven for at least 24 h to allow for digestion of organic material (Catarino et al, 2017).…”

“…Plastic debris was first noted as a potential coastal water problem in 1971 (Carpenter et al, 1972), and MPs (plastic fragments < 5 mm, MPs) are now a widespread form of contamination in marine ecosystems (Moore, 2008;Andrady, 2011), from the Arctic waters (Lusher et al, 2015) to the remote Islands (Ding et al, 2019;Saliu et al, 2019;Tan et al, 2020;Oldenburg et al, 2021) and the coastal waters (Sutton et al, 2016;Yan et al, 2019;Qi et al, 2020;Tsang et al, 2020;Xie et al, 2021). MPs could enter the marine environment via multiple ways, such as ship transportation, fisheries, and domestic sewage discharges (Lusher et al, 2015;Sutton et al, 2016).…”

“…Coral reefs are among the most biologically diverse region in the ocean, providing important ecosystem services to many millions of people, while coral reefs are degrading rapidly in response to various environmental and anthropogenic drivers (Hoegh-Guldberg et al, 2007;Hughes et al, 2017). Recently, high MPs abundance was reported in different coral reef ecosystems (Ding et al, 2019;Saliu et al, 2019;Oldenburg et al, 2021;Tang et al, 2021). MPs could be ingested by corals in the laboratory and natural habitats (Rotjan et al, 2019), which poses another threat to these vital organisms globally (Soares et al, 2020).…”

Abundance and Characteristics of Microplastics in Seawater and Corals From Reef Region of Sanya Bay, China

et al. 2021

Microplastics (MPs) contamination is widespread in the coral reef ecosystems leading to the exposure of both corals and other biotas. Knowledge gaps still exist concerning patterns in MPs abundance spatially. This work quantified the MPs abundance and characteristics in the seawater and corals in the Sanya Bay, Hainan Island. MPs abundance was detected in the seawater and coral samples ranging from 15.50 to 22.14 items L–1, and 0.01 to 3.60 items polyp–1, respectively. We found the predominant size and type of MPs in seawater and corals were smaller than 2 mm and fiber. Further analysis revealed that the characteristics of MPs in the corals were significantly different from those in the seawater environment, indicating that the MPs are selectively enriched in corals. Furthermore, the MPs particles ingested and retained in coral tissue may be related to the polyp size. This study shows that MPs are present in the whole coral reef region and the coral community structure would be potentially harmed by these contaminants.

Coral reef declines have been documented since the 1980’s from a variety of global and local stressors. Management resource tools are needed to preserve these fragile ecosystems from stressors, both known and unknown. Laboratory studies have shown microplastics (MP) to have negative effects on coral physiology, but their effects in a natural environment are not well understood. Thus, our primary objectives were to explore associations between MPs and coral reef attributes. We measured MP concentrations from sub-surface water and coral tissue samples from two Caribbean/Atlantic scleractinian coral species, Montastraea cavernosa and Orbicella faveolata, from St. John, U.S. Virgin Islands and Florida’s Coral Reef in 2017 and 2018, respectively. Polymer identification yielded mostly cotton or polyester fibers for both water and coral tissue samples. This study is the first to document MPs in coral tissues from either the U.S. Virgin Islands or Florida’s Coral Reef and is the first to explore how MPs relate to coral reef attributes. Significant, positive relationships were seen between MPs in coral tissue and coral density, rugosity, and percent coral cover, indicating MPs may not have immediate adverse effects on coral reef health.
