Different sources of particulate organic matter (POM) as well as its composition affect the biological food web and hence the self-purification potential and water quality of rivers. We studied the effect of a large shallow lake on the POM pool of th

Summary UV–Vis spectroscopy was applied to characterize the nature of dissolved organic matter (DOM) in the inflows and in the outflow of the large and shallow temperate Lake Vortsjarv and to determine its temporal and spatial dynamics in 2008–20

Summary The seasonal and spatial changes of content and composition of dissolved organic carbon in water flowing out from bog were studied. Water was sampled from the Kuke River flowing out from Koigi Bog (eastern Saaremaa, Estonia) and in comparison

In this paper, the spatial distribution of the first event of acute myocardial infarction among 35- to 74-year-old men in Finland was examined for the cross-section years 1983, 1988 and 1993. The analysis was performed using a Bayesian hierarchical s

Water Quality Monitoring and Assessment
Different parameters and their combinations are used to evaluate and characterize the quality of the surface water: a) chemometric techniques (Brodnjak-Voncina et al., 2002; Kowalkowski et al. 2006); b) weekly chemical analysis of a wide range of maj
