Abstract

Introduction: Microplastic (MP) contamination poses a global environmental threat, affecting terrestrial and marine ecosystems, and human health. This study investigates the presence, density, and composition of MPs in three commercially important shellfish species, oriental angel wing clam (Pholas orientalis), bamboo clam (Ensis leei), and blood cockles (Tegillarca granosa) at Pantai Remis Jeram, Kuala Selangor. Methods: Microplastics in shellfish were quantitatively analyzed for their abundance, colour, size, shape, and composition using microscopic techniques and micro-Fourier Transform Infrared (FTIR). Standard experimental protocols were followed. Statistical analysis of the data was performed using SPSS to identify correlations between these parameters. Results and Discussion: Our findings reveal a significant presence of MP particles in shellfish with T. granosa exhibiting the highest density (2.417 particles/cm³) compared to E. leei (0.721 particles/cm³) and P. orientalis (1.449 particles/cm³). Fibers and fragments were the dominant MP morphotypes, primarily in black color. P. orientalis and T. granosa contained a majority of MPs within the 1 - 5 mm size range, totalling 41 and 56 particles, respectively. Shellfish samples contain polymers of cellulase acetate and polyethylene terephthalate, indicating possible origins from plastic bottles and textile fibres. A statistically significant difference in the mean MP densities in the different species of shellfish was found by one-way ANOVA analysis (p = 0.042, p < 0.05). Conclusion: This study provides relevant data on MP pollution in commercially significant shellfish species. To effectively mitigate this environmental concern and comprehend the long-term ecological ramifications of MP intake by shellfish, more research is required.

Abstract

Introduction: Emerging environmental contaminants known as microplastics (MPs) have recently attracted a growing amount of attention due to their ubiquitous distribution, high adsorption capability of impurities, high specific surface area, and physiological toxicity, which can remain in the environment for hundreds of years. Thus, this study aimed to characterize microplastics (MPs) and assess their association with varying soil depths and sampling sites, utilizing two distinct plant soil types for comparison. Methods: Soil samples were collected from different depths and various sampling sites within Tanjung Karang, Selangor. The abundance, color, size, shape, and polymer composition of the isolated MPs were analyzed using microscopic techniques and micro-Fourier Transform Infrared (FTIR) spectroscopy. Standard experimental protocols were followed, and one-way ANOVA test was conducted using SPSS. Result and Discussion: Mulched farmland had the most MPs abundance, 1650 particles/kg at 0-10 cm. However, non-mulched farmland had the lowest microplastic abundance at 336 particles/kg at 20-30 cm. This indicates that microplastics were substantially greater in mulched soils than in non-mulched soils. The Stereomicroscope Stemi 305, Zeiss, showed that 64% of films possessed the highest morphotypes, black colour of microplastics made up mostly about 59% of the total, and MPs were the most abundant with a size of <500 μm. ATR-FTIR found mostly polyethylene terephthalate (PET) and polypropylene (PP) polymers in these soils. Also, the abundance of microplastics in both farmlands gradually decreased as the depth of the soil increased. Conclusion: This investigation confirmed that microplastic composition and characteristics vary by agricultural land and soil depth.
