High abundances of microplastic pollution in deep-sea sediments: evidence from Antarctica and the Southern Ocean

first_imgPlastic pollution in Antarctica and the Southern Ocean has been recorded in scientific literature since the 1980s; however, the presence of microplastic particles (<5 mm) is less understood. Here, we aimed to determine whether microplastic accumulation would vary among Antarctic and Southern Ocean regions through studying 30 deep-sea sediment cores. Additionally, we aimed to highlight whether microplastic accumulation was related to sample depth or the sediment characteristics within each core. Sediment cores were digested and separated using a high-density sodium polytungstate solution (SPT) and microplastic particles were identified using micro-Fourier-transform infrared spectroscopy (μFTIR). Microplastic pollution was found in 93% of the sediment cores (28/30). The mean (±SE) microplastics per gram of sediment was 1.30 ± 0.51, 1.09 ± 0.22, and 1.04 ± 0.39 MP/g, for the Antarctic Peninsula, South Sandwich Islands, and South Georgia, respectively. Microplastic fragment accumulation correlated significantly with the percentage of clay within cores, suggesting that microplastics have similar dispersion behavior to low density sediments. Although no difference in microplastic abundance was found among regions, the values were much higher in comparison to less remote ecosystems, suggesting that the Antarctic and Southern Ocean deep-sea accumulates higher numbers of microplastic pollution than previously expected.last_img read more

China pulls U20 football team out of Germany over Tibet protests

first_img0Shares0000The U20 project has courted controversy and become a diplomatic headache for Berlin and Beijing after a pro-Tibetan independence protest during a match in Mainz on November 18 © dpa/AFP/File / Hasan BraticBEIJING, China, Nov 26 – The Chinese FA said Sunday that its under-20 team will return home from Germany after indefinitely suspending its tour over protests by activists who unfurled Tibetan flags at a game.The youth team had been scheduled to play a series of friendlies against German fourth-tier sides until May, aimed at improving China’s chances at the 2020 Tokyo Olympics. But the project has courted controversy and become a diplomatic headache for Berlin and Beijing after a pro-Tibetan independence protest during a match in Mainz on November 18.The German football association (DFB) said last week that the Chinese under-20s would not play the three matches scheduled before the end of the year.Then on Sunday its Chinese counterpart, the CFA, added: “It has been decided to pause the U20 project and arrangements have been made for the team to return home.”0Shares0000(Visited 1 times, 1 visits today)last_img read more
