Exposure to, and risks from synthetic chemicals in terrestrial and freshwater biota: drivers and consequences of landscape scale variation

该项目旨在加深对景观范围内生态系统暴露于合成污染物的时间和空间变化以及对受影响系统的潜在影响的了解。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，以查明毗连的陆地和淡水系统之间以及营养水平之间的化学混合物的差异。将探讨空间和时间差异，作为评估最近/当前监管做法效力的一部分。与我们的利益相关者合作伙伴和广泛的合作网络(例如EA、NRW)合作，这些产出将用于指导选择特定的化学品进行进一步的、有针对性的分析(例如，植物保护产品是预测的重点领域之一)。对于这些目标，将开发预测模型，并将预测与筛查数据进行比较。这是一个令人兴奋的应用项目，由一个经验丰富的监督团队(加的夫大学、英国赫伯特大学、先正达、HSE CRD)领导，他们在淡水生态、生态毒物分析和统计建模方面拥有专业知识。它汇聚了一个跨学科(和国际)的合作者网络，涉及学术界、工业界和监管当局，以及获取大量样本和数据档案。

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.
