• Mercury and amino acid content relations in northern pike (Esox lucius) in subarctic lakes along a climate-productivity gradient 

  Kozak, Natalia; Kahilainen, Kimmo K.; Pakkanen, Hannu K.; Hayden, Brian; Østbye, Kjartan; Taipale, Sami J. (Elsevier, 2023)

  Mercury is a highly toxic element for consumers, but its relation to amino acids and physiology of wild fish is not well known. The main aim of this study was to evaluate how total mercury content (THg) of northern pike ...

• Environmental and biological factors are joint drivers of mercury biomagnification in subarctic lake food webs along a climate and productivity gradient 

  Kozak, Natalia; Ahonen, Salla A.; Keva, Ossi; Østbye, Kjartan; Taipale, Sami J.; Hayden, Brian; Kahilainen, Kimmo K. (Elsevier, 2021)

  Subarctic lakes are getting warmer and more productive due to the joint effects of climate change and intensive land-use practices (e.g. forest clear-cutting and peatland ditching), processes that potentially increase ...

• Allochthony, fatty acid and mercury trends in muscle of Eurasian perch (Perca fluviatilis) along boreal environmental gradients 

  Keva, Ossi; Kiljunen, Mikko; Hämäläinen, Heikki; Jones, Roger I.; Kahilainen, Kimmo K.; Kankaala, Paula; Laine, Miikka B.; Schilder, Jos; Strandberg, Ursula; Vesterinen, Jussi; Taipale, Sami J. (Elsevier, 2022)

  Environmental change, including joint effects of increasing dissolved organic carbon (DOC) and total phosphorus (TP) in boreal northern lakes could potentially affects food web energy sources and the biochemical composition ...

• Preconcentration and speciation analysis of mercury : 3D printed metal scavenger-based solid-phase extraction followed by analysis with inductively coupled plasma mass spectrometry 

  Kulomäki, Suvi; Lahtinen, Elmeri; Perämäki, Siiri; Väisänen, Ari (Elsevier BV, 2022)

  A selective method for preconcentration and determination of methylmercury (MeHg) and inorganic mercury (iHg) in natural water samples at the ng L−1 level has been developed. The method involves adsorption of Hg species ...

• UV-B Exposure Causes DNA Damage and Changes in Protein Expression in Northern Pike (Esox lucius) Posthatched Embryos 

  Vehniäinen, Eeva-Riikka; Vähäkangas, Kirsi; Oikari, Aimo (John Wiley & Sons, 2012)

  The ongoing anthropogenically caused ozone depletion and climate change has increased the amount of biologically harmful UV-B radiation, which is detrimental to fish in embryonal stages. The effects of UV-B radiation ...
