    Research on microplastics must be harmonized. Therefore, we thoroughly evaluated in the Association of Southeast Asian Nations (ASEAN) region, addressing challenges and priorities in protocol harmonization and microplastics research promotion. Of the 615 papers searched by the Web of Science, 164 were used for this systematic review. The number of ASEAN research articles has increased over time. Examination of research protocols in various sampling environments revealed several challenges: 1) Disparities in access to sampling locations affect the research extent; 2) Outdated protocols and limited access to technologies such as FTIR (Fourier-transform infrared) spectroscopy result in less harmonized and potentially lower-quality data; and 3) Insufficiently detailed methods and QA/QC information hampers comparability. We offer procedure updates to overcome these limitations and cover environmental microplastic study gaps. Other countries in the Global South may encounter similar challenges, making this review a valuable contribution to advancing global microplastics research and fostering international collaboration.

    Individual coral polyps contain three distinct components—the surface mucus layer, tissue, and skeleton; each component may exhibit varying extent of microplastic (MP) accumulation and serve as a short- or long-term repository for these pollutants. However, the literature on MP accumulation in wild corals, particularly with respect to the different components, is limited. In this study, we investigated the adhesion and accumulation of MPs in four coral species, including both large (Lobophyllia sp. and Platygyra sinensis) and small (Pocillopora cf. damicornis and Porites lutea) polyp corals collected from Si Chang Island in the upper Gulf of Thailand. The results revealed that MP accumulation varied significantly among the four coral species and their components. Specifically, P. cf. damicornis exhibited the highest degree of accumulation (2.28 ± 0.34 particles g−1 w.w.) [Tukey's honestly significant difference (HSD) test, p < 0.05], particularly in their skeleton (52.63 %) and with a notable presence of high-density MPs (Fisher's extract test, p < 0.05). The most common MP morphotype was fragment, accounting for 75.29 % of the total MPs found in the coral. Notably, the majority of MPs were black, white, or blue, accounting for 36.20 %, 15.52 %, and 11.49 % of the samples, respectively. The predominant size range of MP particles was 101–200 μm. Nylon, polyacetylene, and polyethylene terephthalate (PET) were the prevalent polymer types, accounting for 20.11 %, 14.37 %, and 9.77 % of the identified samples, respectively. In the large polyp corals, while MP shapes, colors, and sizes exhibited consistent patterns, remarkable differences were noted in the polymer types across the three components. The findings of this study improve the understanding of MP accumulation and its fate in coral reef ecosystems, underscoring the need for further investigation into MP-accumulation patterns in reef-building corals worldwide.

  • Small microplastic ingestion by the calanoid <i>Centropages furcatus</i> in the Gulf of Thailand

    Microplastics could be ingested by many organisms, including zooplankton, involving bioaccumulation and biomagnification mechanisms a cross food webs. The information about microplastic ingestion by zooplankton keeps increasing worldwide. However, it is still limited for particle sizes under 300 μm (small microplastics, SMPs) and in areas such as Southeast Asia, which is considered one of the hotspots for plastic debris. This study aimed to characterize the size, shape, and polymer types of the SMPs ingested by the copepod Centropages furcatus in Si Chang Island (upper Gulf of Thailand). The study spans offshore and coastal waters, with data collected across wet, intermediate, and dry seasons. Using a semi-automated technique for micro-FTIR (Fourier-transform infrared) scanning spectroscopy for particle analysis, we found ingested SMPs in all samples. A total of 750 individuals of the calanoid Centropages furcatus were analyzed, finding 309 plastic particles and an average ingestion value of 0.41 ± 0.13 particles ind−1, one of the highest recorded values. All the particles were fragments, with a predominant size under 50 μm, and polymer types as Polypropylene (PP, 71 %), followed by Ethylene-Propylene-Diene-Monomer (EPDM, 16 %) and Polyethylene (PE, 7 %). Up to 470.2 particles m−3 were estimated to be retained by this calanoid species and potentially available for trophic transfer. The effect of rainfall on SMPs ingestion was inconclusive, with a non-significant observed tendency to higher ingestion values near the coastal area than offshore area, suggesting a decrease in particle exposure due to the runoff effect. Nevertheless, future studies should increase the frequency of surveys to arrive at better conclusions.

    The exponential increase in microplastics (MPs) within the global ocean has been extensively documented. Various marine organisms have been identified as key contributors to the removal of MPs through biological processes. Coral, as a sessile animal, has a unique physiology and growth pattern that may be interesting for MP accumulation studies. Although it is well known that a coral colony consists of three parts— the surface mucus layer, tissue, and skeleton—each part may be responsible for different accumulations of MPs, whether as short or long-term sinks for MPs. Surprisingly, no previous study has provided MP extraction data for each coral part. Therefore, this study investigated the adhesion and accumulation of MPs in four species, including small and large polyps corals from Si Chang Island in the upper Gulf of Thailand. Furthermore, we refined the methodology for MP extraction, enabling investigation across distinct coral parts. The outcomes of this research provide crucial data regarding the interactions between corals and MPs, elucidating their capacity to temporally and permanently sequester MP particles from the surrounding environment.

    Reef-building corals are threatened by plastic pollution, particularly by microplastics (MPs), which are plastic particles less than 5 mm. When MPs reach the ocean, particles can float on the sea surface and accumulate in the water column and sediment. Coral is a sessile organism that can interact with MPs by active ingestion and by passive adhesion of particles (e.g., by wave action). However, the occurrence of MPs on coral reefs at different seasons and tidal ranges are still poorly understood. Here, we investigated the presence of MPs adhesion in scleractinian corals and their ingestion at Si Chang Island (upper Gulf of Thailand). Coral organisms, seawater and sediment samples were collected at different tidal ranges (spring and neat tides) during the wet (August and October 2022) and dry (March and May 2023) seasons. The characteristics of MPs were categorized according to size, color, shape, and polymer type (FTIR). The results of this study confirmed the presence of MPs particles of diverse polymer types in the different samples in the coral reef area. Further studies should be considered to assess the potential impact of plastic particles on coral organisms. The results of this research contribute to understanding the effects of plastic pollution on reef-building corals and improve the strategies for local waste management and coral reef conservation in Thailand.

    The accumulation of microplastics (MPs) in the food chain poses a risk to food security and human health. Although several studies have found the presence of MPs across commercial species worldwide, the trophic transfer route of MPs via their food web is not well established. The aim of this study was to investigate the MPs abundance, characteristics, polymer type within the stomach and the potential of MPs transfer through the food chain of Russell's snapper (Lutjanus rusellii). Numerous MPs polymer types were identified by FT-IR. The lower trophic lelvels organisms such as zooplankton and small fishes can ingest several MPs types. Moreover, the potential of trophic transfer of MPs from snapper's prey has been examined in this study.
