项目摘要

This interdisciplinary project seeks to understand the risks posed by soil contamination byanthropogenic activities above- and below-ground in urban ecosystems. This is crucial as soils inurban ecosystems experience high levels of contamination from heavy industry, transport and humanmanagement (e.g. pesticides and herbicides at unregulated rates) and the impact of these on thestructure and function of urban soil ecosystems are unknown. Our supervisory team is uniquelyplaced to deliver this project with expertise in urban ecosystems, plant-soil-microbe interactions andthe impact of pesticides in the environment on wildlife.Currently, nothing is known about how heavy metal and chemical contaminants impact soil microbialand fungal community structure and function in urban ecosystems, and how this impacts on theassociated wildlife in above- and below-ground ecosystems. This project will provide key insights intothese processes producing a new framework for assessment of environmental risk of soilcontaminants.The student appointed to this project will develop a range of skills in soil, plant and microbialsciences, including analytical chemistry, metabolomics, isotope tracing and metagenomics. Inaddition, the student will undertake fieldwork and develop associated skills in citizen science,working with local authorities and the general public.

这一跨学科项目旨在了解城市生态系统中人类活动造成的土壤污染所带来的风险。这一点至关重要，因为城市生态系统中的土壤受到重工业、交通运输和人类管理的高度污染（例如农药和除草剂的使用率不受管制），这些污染对城市土壤生态系统的结构和功能的影响尚不清楚。我们的监督团队在城市生态系统、植物-土壤-微生物相互作用以及环境中农药对野生动物的影响方面拥有丰富的专业知识，能够很好地完成该项目。目前，我们还不知道重金属和化学污染物如何影响城市生态系统中的土壤微生物和真菌群落结构和功能，以及如何影响地上和地下生态系统中的相关野生动物。该项目将为这些过程提供关键的见解，为土壤污染物的环境风险评估提供一个新的框架。被任命参加该项目的学生将在土壤，植物和微生物科学方面发展一系列技能，包括分析化学，代谢组学，同位素示踪和宏基因组学。此外，学生将进行实地考察，并发展公民科学的相关技能，与地方当局和公众合作。
