This PhD project will analyse the fate, transport and impacts of MnP from soils to groundwater to develop solutions to reduce the environmental and public health risks posed by MnP in groundwater. The PhD will therefore investigate potential risks of MnP, their additives and adsorbed pollutants that can impact the soil and groundwater microbiome with potentially drastic consequences for water quality and the natural attenuation capacity of groundwater aquifers. Following an interdisciplinary multi-method approach, this PhD project will develop and integrate field and laboratory experimental capacity with numerical modelling tools to provide detailed understanding of the transport mechanisms and time scales of soil and groundwater MnP fluxes and interactions due to properties of MnP coronas. It will quantify aquifer type and land use specific MnP transit and peak arrival times for a wide range of currently circulating synthetic polymers, characterise MnP properties encountered in the field as well as novel biodegradable polymers. The quantification of travel and transit time dependent leaching of selected plastic additives and adsorbed pollutants will enable identification of material property and context dependent risk profiles that will assist private and public sectors in understanding environmental and public health risks posed by MnP.

该博士学位项目将分析MNP从土壤到地下水的命运，运输和影响，以开发解决方案，以降低MNP在地下水中带来的环境和公共卫生风险。因此，该博士将研究MNP的潜在风险，它们的添加剂和吸附的污染物，这些污染物可能会影响土壤和地下水微生物组，并可能对水质质量以及地下水含水层的自然衰减能力产生巨大影响。遵循跨学科的多方法方法，该博士学位项目将与数值建模工具一起开发和整合实验室和实验室实验能力，以详细了解土壤和地下水MNP磁通量以及由于MNP Coronas的性质而引起的土壤和地下水MNP磁通量。它将对当前循环的合成聚合物的广泛范围量化含水层类型和土地使用特定的MNP传输和峰值到达时间，这表征了现场遇到的MNP特性以及新型的可生物降解聚合物。对选定塑料添加剂和吸附的污染物的旅行和运输时间依赖浸出的量化将有助于鉴定物质财产和背景风险概况，这将有助于私营和公共部门了解MNP构成的环境和公共卫生风险。
