Microplastics Prevalence in Different Cetaceans Stranded along the Western Taiwan Strait
Microplastics (MPs) pollution is of global concern, which poses serious threats to various marine organisms, including many threatened apex predators. In this study, MPs were investigated from nine cetaceans of four different species, comprising one common dolphin (<i>Delphinus delphis</i&g...

description | Microplastics (MPs) pollution is of global concern, which poses serious threats to various marine organisms, including many threatened apex predators. In this study, MPs were investigated from nine cetaceans of four different species, comprising one common dolphin (<i>Delphinus delphis</i>), two pygmy sperm whales (<i>Kogia breviceps</i>), one ginkgo-toothed beaked whale (<i>Mesoplodon ginkgodens</i>), and five Indo-Pacific humpback dolphins (<i>Sousa chinensis</i>) stranded along the western coast of the Taiwan Strait from the East China Sea based on Fourier transform infrared (FTIR) spectroscopy analysis. Mean abundances of 778 identified MPs items were 86.44 ± 12.22 items individual<sup>−1</sup> and 0.43 ± 0.19 items g<sup>−1</sup> wet weight of intestine contents, which were found predominantly to be transparent, fiber-shaped polyethylene terephthalate (PET) items usually between 0.5 and 5 mm. The abundance of MPs was found at a slightly higher level and significantly correlated with intestine contents mass (<i>p</i> = 0.0004*). The MPs source was mainly likely from synthetic fibers-laden sewage discharged from intense textile industries. Our report represents the first study of MPs in pelagic and deep-diving cetaceans in China, which not only adds baseline data on MPs for cetaceans in Asian waters but also highlights the further risk assessment of MPs consumption in these threatened species. |
