项目摘要

The South East (SE) Asian region releases every year into the ocean more than four million tonnes of plastic waste and is facing one of the most important marine plastic pollution crises on our planet, threatening the biodiversity of marine ecosystems, coastal tourism, fisheries and aquaculture, which are vital for the economic growth of the region. Plastics debris are persistent in the marine environment are dominated by the smaller abundant microplastic (MP) particles, that are of increasing concern. The toxicity of marine MPs vary with their abundance, size, shape, chemical properties, and composition of their microbial biofilm. The surface of MP particles, referred to as the plastisphere, serves as a support for the colonisation of microorganisms where they may be protected area with limited predation. Microbial biofilms inhabiting the plastisphere are specific to this habitat and can include both plastic degraders and/or harmful pathogens. MPs are also potential vectors for other toxic contaminants found in coastal environments that could translate into health issues for society and ecosystems. Marine MPs are inherently complex due to the varying composition of compounds, which will determine the specific buoyancy and surface rugosity, which in turn dictates the extent of microbial colonisation and potential for long distance dispersal. To determine the natural biological and photochemical degradability of marine MPs and to quantify the impacts of marine MPs on marine ecosystems, aquaculture and human health, it is essential to use a combination of fieldwork and advanced molecular techniques in the laboratory, and tackle the plastic pollution crisis with this new angle. Our team will conduct a comprehensive investigation of the impact of microplastic particles on microorganisms sampled from different regions in SE Asia, spanning a range of different physical and chemical water typologies. Modelling the transport of MP particles will identify a network of sources and sinks across SE Asia and provide a temporal data on the risks associated with microplastics. We will deploy advanced, state-of-the art techniques to quantify the impact the abundant microplastic particles at different trophic levels from the complex microbial communities inhabiting the surface of MPs, to bivalves and fish. We will identify new microbial degraders, key enzymes involved in biodegradation pathways and understand how sunlight can enhance the (bio)degradability of recalcitrant polymers. The overarching aim of this project is to provide new insights on the biological and photochemical degradability of marine MP, deciphering the role of the plastisphere for degrading marine MPs and disseminating pathogens to human and aquaculture receptors. Our project will deliver an important step forward by offering decision-making tools and guidelines for future coastal policies and regulations in relation to: (i) plastic sustainability, banning the most harmful polymers (ii) photocatalysis and wastewater treatments (iii) bio-recycling of plastics and classification of the most hazardous plastic polymers and (iv) food safety and human exposure risks. Our long-term vision is that our results will benefit the overall economy in SE Asia by providing the necessary knowledge to reduce the volume of marine MPs, which will ultimately lead to healthier coastal tourism, fisheries and aquaculture.

东南（SE）亚洲地区每年都在海洋中释放超过400万吨塑料废物，并面临着我们星球上最重要的海洋塑料污染危机之一，威胁着海洋生态系统，沿海旅游，渔业和水产养殖的生物多样性，这对于该地区的经济增长至关重要。在海洋环境中，塑料碎片持续存在，这是较小的丰富的微型（MP）颗粒，这些颗粒越来越引起人们的关注。海洋MP的毒性随着其微生物生物膜的丰度，大小，形状，化学性质和组成而变化。 MP颗粒的表面（称为塑料）可以支持微生物的定殖，在这种情况下，它们可能受到有限的捕食保护区域。居住在质体中的微生物生物膜特有该栖息地，并且可以包括塑料降解器和/或有害病原体。国会议员也是在沿海环境中发现的其他有毒污染物的潜在向量，这些污染物可能转化为社会和生态系统的健康问题。由于化合物的组成变化，海洋MPS固有地很复杂，这将决定特定的浮力和表面皱纹，这反过来又决定了微生物定殖的程度和长距离分散的潜力。为了确定海洋MPS的自然生物学和光化学降解性，并量化海洋MP对海洋生态系统，水产养殖和人类健康的影响，必须在实验室中使用现场工作和先进的分子技术，并以这种新的角度来解决塑料污染危机。我们的团队将全面研究微塑料颗粒对SE亚洲不同地区采样的微生物的影响，涵盖了一系列不同的物理和化学水类型。建模MP颗粒的运输将确定在SE亚洲的来源和下沉网络，并提供有关与微塑料相关的风险的时间数据。我们将部署先进的最先进技术，以量化从居住在MPs表面的复杂微生物群落到双壳类和鱼类的复杂微生物群落的不同营养水平上的丰富微型颗粒的影响。我们将确定与生物降解途径有关的新微生物降解器，关键酶，并了解阳光如何增强顽固聚合物的（生物）降解性。该项目的总体目的是提供有关海洋MP生物学和光化学降解性的新见解，从而解密了质体在降解海洋MP并将病原体传播到人类和水产养殖受体中的作用。我们的项目将通过为未来的沿海政策和法规提供有关：（i）塑料可持续性，禁止最有害的聚合物（II）光催化和废水处理（III）生物恢复塑料和最危险的塑料塑料polymers and Humans（IV）和人类（IV）的塑料可持续性（III），将迈出重要的一步。我们的长期愿景是，我们的业绩将通过提供必要的知识来减少海洋议员的数量，从而使SE亚洲的整体经济受益，这最终将导致更健康的沿海旅游，渔业和水产养殖。
