The present study is based on sediment samples collected from three Arctic freshwater lakes over a period of 4 years (2015–2018). The samples were analysed for total mercury (THg), met ...

Abstract:: ... Several national-scale studies have shown that reactive N is accumulating in developed countries even when only the terrestrial biosphere is considered. However, none of these studies was able to consider the total N budget and so any discrepancy in budgets could be dismissed as being accounted for by N₂exchange. This study considered a large (9,948 km²), mixed agricultural catchment where records ...
