“…In addition, de Moura and Vianna [ 41 ] reported that the ingestion of microplastics in the teleost fish was commonly fibres (20.2%) and fragments (22%). In the southern region of Thailand, some studies have been conducted on plastic debris in commercial fish and shrimp species [ 25 , 35 , 36 , 39 , 71 ]. Compared with the present study, there were different results depending on the study focus by species.…”

“…Meanwhile, consumption of microplastics can have negative effects on growth, reproduction, and survival evidence, although most of the effects are sublethal [ 23 , 24 ]. In addition, soft or thin plastic fragments on muddy beaches are found in higher amounts than other debris types that may have a harmful impact on marine organisms [ 25 ]. Specifically, plastic debris from anthropogenic activity occurs regardless of the season, area, or ontogenetic phase and may be passed through direct consumption and prey items [ 26 ].…”

“…In addition, higher ingestion of microplastics was found in some commercial shrimp than in fish, most of the microplastics being fibres from textiles and fishing nets in Thailand [ 39 ]. However, the occurrence of ceramic and glass debris is greater than plastic and other debris in beach sediment due to shoreline and recreational activities [ 25 ].…”

This study assessed the feeding habits and ingestion of anthropogenic debris in 34 marine fish species from the southern Gulf of Thailand. A total of 5478 fish samples of 12 families were categorised into seven groups: planktivore, Lucifer feeder, fish feeder, Acetes feeder, shrimp feeder, piscivore, and zoobenthivore fish. A total of 2477 anthropogenic debris items were extracted from 12 fish species by visual inspection. Their ingestion of anthropogenic debris was influenced by season (p < 0.0001), with the highest ingestion during the northeast monsoon season. Furthermore, planktivorous fish displayed more ingested anthropogenic debris than the other investigated species (p = 0.022). Blue-coloured anthropogenic debris was commonly detected in the stomachs of fish and significantly differed between species (p > 0.001). Water depth and season significantly influenced the availability of food types (AF) for fish (p < 0.001). These findings provide evidence of the ingestion of anthropogenic debris by fish inhabiting a natural bay and signal the future anthropogenic pollution of marine fish.

“…It might be that, while the study area is located on a National Marine park, anthropogenic activities in households and agriculture around the park might contribute trace metal contamination to this area. Recently, Pradit et al reported on marine waste, such as ceramic garbage, microplastic, batteries, etc., being released from the communities on Libong Island, due to influences of monsoon winds from May to October [18]. Thus, it might be that pollution from the mainland is released and transported by the seawater, and accumulates in the sediments at this remote location.…”

“…An increasing number of tourists are visiting this island to observe the dugong and enjoy seafood, particularly wing shell meals. Recently, Pradit et al 2020 reported on marine waste and hazardous waste, including batteries, on Libong Island, which were released from the mainland [18]. Moreover, activities around Libong Island, such as household activities, tourism, rubber industry, and agricultural activities, could be sources of trace metals that may affect aquatic animals and humans who consume the shellfish contaminated with trace metals.…”

The present study determined the metal levels in surface sediment and in soft tissue of the Strombus canarium at Libong Island, Thailand, and estimated the possible risk from consuming the shellfish. The mean concentrations of the metals Fe, Cu, Co, Pb, Mn, and Ni in sediment were 2711.94 ± 1424.83, 0.47 ± 0.37, 0.11 ± 0.09, 1.32 ± 1.48, 40.41 ± 16.12, and 2.75 ± 4.04 µg/g, respectively, and are below the sediment quality guidelines. The enrichment factor (EF) and geoaccumulation index (Igeo) showed that the sediment conditions ranged from “no pollution” to “moderate contamination”. The mean concentrations in Strombus canarium had rank order Fe > Mn > Cu > Ni > Co > Pb. The bioaccumulation (BSAF) suggests that the Strombus canarium accumulated Cu and Co the most. The estimated daily intakes of these metals through shellfish consumption were below the oral reference dose (Rfd) and the calculated target hazard quotients (THQ) were less than 1. The results from this study inform about the background levels of metals in the sediment and in Strombus canarium species at Libong Island. In addition, these data might help ensure that the consumption of shellfish in this area remains safe.

Marine debris characteristics in various coastal typologies in the Gunungkidul coastal area of Yogyakarta—Indonesia

Marine debris is one of the environmental issues that can be brought on by rapid human development and activity, including marine tourism, like what happened in the coastal area of Gunungkidul, Indonesia. The issue of marine debris might decrease the environmental quality and impact tourism in Gunungkidul. This study aims to identify the characteristics of coastal typologies in Gunungkidul and analyze their influence on the characteristics of marine debris. Google Earth images and the Digital Elevation Model were used to interpret and classify the typology across the study area based on their physical characteristics. Marine debris samples, either macro or meso-sized, were collected using the transect method for each beach. Based on the imagery interpretation combined with elevation data from DEMNAS, there are three typologies in the Gunungkidul coastal area, i.e., pocket, non-pocket, and cliff beaches. Cliff typology was eliminated and only pocket and non-pocket beaches were used as marine debris sample collection locations. Hence, four beaches were chosen as study areas, i.e., Seruni, Drini, Sepanjang, and Sedahan; each represents each coastal typology. About 193 macro-sized and 217 meso-sized debris were found in our research area, totaling 1380.31 g. Compared to non-pocket beaches, pocket beaches contain more marine debris. The higher slopes of the pocket beach typology will trap marine debris and make it challenging to reenter the water. On pocket beaches, oceanographic processes concentrate marine debris in one location. Still, on non-pocket beaches, marine debris can disperse and return to the sea more readily due to the cycling of currents near the coast.
