Occurrence of pharmaceuticals in municipal wastewater treatment plants and receiving surface waters in Central and Southern Finland
2016
The presence of five selected pharmaceuticals, four anti-inflammatory drugs, diclofenac, ibuprofen, ketoprofen, naproxen, and an antiepileptic drug carbamazepine, was determined at four municipal wastewater treatment plants (WWTPs) and in the receiving waterway near the city of Jyväskylä, in central Finland and also in the River Vantaa. First, an analytical method was developed including a pretreatment and purification followed by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) in the multiple reaction monitoring mode. The studied pharmaceuticals were detected from influents and effluents of four municipal WWTPs and from surface water of eight locations along the water …
Seasonal variations in endurance performance, and aerobic and anaerobic variables in competitive cross country skiers
2016
Cross country skiing is known as an endurance sport and both aerobic and anaerobic systems have a major impact on performance in cross country skiers. Coaches and athletes use periodized training programs to optimize physiological adaptations and increase performance. Knowing how the major aerobic and anaerobic variables change during the course of one ski season will allow better implementation of training programs. This study examined variations in endurance performance, and how that relates to the variation in different aerobic and anaerobic variables. There were 19 subjects in the study, 11 male and 8 female. All subjects were competitive cross country skiers. The study took place over …
Seasonal variation in diversity of marine benthic invertebrates leads to a positive species-genetic diversity correlation (SGDC)
2018
Species-genetic diversity correlations (SGDCs) are useful indicators of processes that simultaneously affect diversity at multiple biological levels. We combined spatial and temporal sampling of 4 study sites in the Danish Isefjord-Roskilde Fjord Estuary at 4 time points over 1 yr to investigate the effect of seasonal variation on SGDCs. Species diversity was estimated as species richness from samples comprising 20752 individuals representing 51 benthic invertebrate taxa. Genetic diversity was estimated for a single focal taxon, the polychaete Pygospio elegans, as mean allelic richness at 7 microsatellite loci. Combining all samples, a significant positive correlation between species richne…
