To monitor environmental pollutants in Faroese biota, samples from a top predator were analysed and put into a spatial and temporal context. Analysis of 20 Great Skua eggs sampled in 2012 from the Faroe Islands showed >70 % lower concentrations of legacy persistent organic pollutants (POPs) than in samples analysed in 1977. The 2012 Faroese eggs showed higher concentrations than for eggs in Shetland from about the same period (2008). Eggshells were analysed for sub-lethal effects but there were no detectable effects of legacy POP levels on eggshell colour or thickness. A temporal decline in legacy POPs would indicate a reduction in the general pollutant levels present in the environment as has been shown in other areas of the North Atlantic, but there are significant geographic differences in POPs levels likely due to differences in diet resulting in significantly different exposures on a relatively limited spatial scale.
为监测法罗群岛生物群中的环境污染物，对一种顶级捕食者的样本进行了分析，并将其置于时空背景下。对2012年从法罗群岛采集的20枚大贼鸥蛋进行分析，结果显示，遗留持久性有机污染物（POPs）的浓度比1977年分析的样本低70%以上。2012年法罗群岛的蛋显示出的浓度高于同期（2008年）设得兰群岛的蛋。对蛋壳进行了亚致死效应分析，但遗留POPs水平对蛋壳颜色或厚度没有可检测到的影响。遗留POPs的时间下降表明环境中存在的总体污染物水平有所降低，这在北大西洋的其他地区也有显示，但POPs水平存在显著的地理差异，这可能是由于饮食差异导致在相对有限的空间尺度上暴露程度显著不同。
