TL;DR: In this paper, emissions, bioaccumulation and possible food chain enrichment of polychlorinated phenols, guaiacols and catechols have been studied by analyses of water, snow, ash, benthic animal, fish and bird samples in Finland.

TL;DR: In this article, food chain and sediment samples of three lake areas in Middle Finland have been analyzed for their chlorophenol contamination using twelve model compounds which are main residues of chlorobleaching and wood preservation.

TL;DR: Chlorohydrocarbons and free and chemically bound chlorophenols, catechols and guaiacols were measured from lake sediments in Central Finland as mentioned in this paper, where they occurred at low backround levels except chlorocymenes from pulp mills and PCBs near the city of Aanekoski.

TL;DR: In this article, a study of lakes polluted by pulp mill and urban wastes including chlorobleaching of pulp, semipolluted lakes and reference lakes in nearly natural condition in Central Finland were studied for contents of mercury, methyl mercury and organochlorine compounds in sediment, plankton, roach and pike.

TL;DR: In this paper, the meiofauna was studied from springs in Finland which was completely ice-covered during the last glacial epoch, and 15 springs were in areas considered to bein anatural state and 16 had catchment areas subject to anthropogenicdisturbance from one of four sources: agriculture,inhabitation, gravel extraction or winter road de-icing with NaCl.
