The project aims to develop a deeper understanding of the temporal and spatial variation in ecosystem exposure to synthetic pollutants, at a landscape scale, and potential implications for affected systems. Existing data (target and non-target screening data) held by the supervisory partnership will be analysed to identify differences in chemical mixtures between contiguous terrestrial and freshwater systems, and between trophic levels. Spatial and temporal variation will be explored as part of an evaluation of the efficacy of recent/current regulatory practices. Working with our stakeholder partners and wide collaborative network (e.g. EA, NRW) these outputs will be used to guide selection of specific chemicals for further, targeted, analyses (e.g. plant protection products are one of the projected focal areas). For these targets, predictive models will be developed, and predictions compared with screening data. This is an exciting and applied project, led by an experienced supervisory team (Cardiff University, UKCEH, Syngenta, HSE CRD) with expertise in freshwater ecology, ecotoxicological analysis, and statistical modelling. It brings together a cross-disciplinary (and international) network of collaborators, across academia, industry and the regulatory authority, as well as access to extensive sample and data archives.

该项目旨在深入了解生态系统在景观尺度上暴露于合成污染物的时空变化，以及对受影响系统的潜在影响。将对监督伙伴关系持有的现有数据（目标和非目标筛选数据）进行分析，以确定相邻陆地和淡水系统之间以及营养水平之间化学混合物的差异。空间和时间变化将作为评估最近/当前监管实践有效性的一部分进行探讨。与我们的利益相关者合作伙伴和广泛的协作网络（例如EA， NRW）合作，这些产出将用于指导选择特定化学品进行进一步的，有针对性的分析（例如植物保护产品是预计的重点领域之一）。针对这些靶点，将建立预测模型，并将预测结果与筛选数据进行比较。这是一个令人兴奋的应用项目，由一个经验丰富的管理团队（卡迪夫大学，UKCEH，先正达，HSE CRD）领导，他们在淡水生态学，生态毒理学分析和统计建模方面具有专业知识。它汇集了跨学术界、工业界和监管机构的跨学科（和国际）合作者网络，以及对广泛样本和数据档案的访问。
