Concentrations of different chlorinated compounds were measured in mussels incubated in two polluted watercourses, a river (the River Kymijoki) and a lake (Lake Vanaja) for four weeks in summer 1995. The sum concentrations of polychlorinated phenols

The distribution of organochlorines in aquatic ecosystem was followed by simultaneous incubation of mussels and solvent filled dialysis membranes. The uptake of organochlorines by the mussel represents both active and passive processes while the solv

Chlorohydrocarbons and free and chemically bound chlorophenols, catechols and guaiacols were measured from lake sediments in Central Finland. Chlorohydrocarbons occurred at low backround levels except chlorocymenes from pulp mills and PCBs near the c

Organically bound chlorine together with inorganic chloride was measured from dated bottom sediment layers of 18 lakes in Central Finland and compared to organic matter contents. Pulp mills were found to be the source of significant increase of the a

PCB mixtures occur in amounts of 5 to 6000 ppb in paper products made of recycled material. Contents in samples made from Central-European raw material were higher than those from Finnish material. However, the origin of some samples with high conten

Model compounds of polychlorinated anisoles (PCA) and veratroles (PCV) have been used in development of their analysis in fish. Individual PCAs and PCVs in fish were identified from GC peaks by retention time, selected ion monitoring and flavour in s

Chlorobleaching of pulp is the most important source of organochlorine pollutants in the Finnish aquatic ecosystems. Similar types of pollutants are formed during chlorodisinfection of water. The model compound approach employed in our laboratory has

Chloride, total organic chlorine (TOCl) and chlorophenols have been measured in bottom sediment layers of seven lakes in Central Finland. Organic chlorine compounds were found even in layers formed in the 13th century. However, the amounts increase m

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. Seventeen individual compounds were
