AB  - Bacterial communities in the Arctic environment are subject to multiple stress 
      factors, including contaminants, although typically their concentrations are 
      small. The Arctic contamination research has focused on persistent organic 
      pollutants (POPs) because they are bioaccumulative, resistant to degradation and 
      toxic for all organisms. Pollutants have entered the Arctic predominantly by 
      atmospheric and oceanic long-range transport, and this was facilitated by their 
      volatile or semi-volatile properties, while their chemical stability extended 
      their lifetimes following emission. Chemicals present in the Arctic at detectable 
      and quantifiable concentrations testify to their global impact. Chemical 
      contamination may induce serious disorders in the integrity of polar ecosystems 
      influencing the growth of bacterial communities. In this study, the abundance and 
      the types of bacteria in the Arctic freshwater were examined and the microbial 
      characteristics were compared to the amount of potentially harmful chemical 
      compounds in particular elements of the Arctic catchment. The highest 
      concentrations of all determined PAHs were observed in two samples in the 
      vicinity of the estuary both in June and September 2016 and were 1964 ng L(-1) 
      (R12) and 3901 ng L(-1) (R13) in June, and 2179 ng L(-1) (R12) and 1349 ng L(-1) 
      (R13) in September. Remarkable concentrations of the sum of phenols and 
      formaldehyde were detected also at the outflow of the Revelva river into the sea 
      (R12) and were 0.24 mg L(-1) in June and 0.35 mg L(-1) in September 2016. The 
      elevated concentrations of chemical compounds near the estuary suggest a 
      potential impact of the water from the lower tributaries (including the 
      glacier-fed stream measured at R13) or the sea currents and the sea aerosol as 
      pollutant sources. The POPs' degradation at low temperature is not well 
      understood but bacteria capable to degrading such compounds were noted in each 
      sampling point.
