Due to the decrease in population of the common Kestrel in the United Kingdom, concerns have been raised about the use of Second generation anticoagulants. It is believed that the raptors are exposed to these compound through secondary exposure, mainly from their diet, with a negative correlation between SGARs liver concentrations and population change. Therefore, the study aims to analyse the fitness and population of common Kestrels exposed to SGARs. The objectives are to generate a methodology to evaluate the effects of SGARs using measurements in biological media, such as blood samples, that are then extrapolated to the liver which are then used to evaluate the impact of SGARS on fitness and to evaluate the degree of impact that these compounds have on the population. Spatial risk will be characterised by evaluating the concentration of SGARs in a gradient of exposure.

由于英国红隼数量的减少，人们对第二代抗凝剂的使用产生了担忧。据信，猛禽通过二次接触（主要是通过饮食）接触到这些化合物，肝脏中的 SGAR 浓度与种群变化呈负相关。因此，本研究旨在分析接触 SGAR 的普通红隼的健康状况和种群数量。目标是建立一种方法，通过对生物介质（例如血液样本）进行测量来评估 SGAR 的影响，然后将其外推到肝脏，然后用于评估 SGAR 对健康的影响，并评估这些化合物对人群的影响程度。空间风险将通过评估暴露梯度中 SGAR 的浓度来表征。
