The aim of the investigations was to ascertain the source of the lead. Previous research had revealed a correlation between lead and nitrate concentrations. Hence, a common source was assumed. To discover the origin of the lead and nitrate, their isotopic composition was determined

The aim of the tracer experiments was to provide a basis for norms establishing the quality of sewage from major pulp and paper plants which discharge their liquid wastes into these water bodies. 3 refs, 1 fig

The whole catchment area (6 km2) is used predominantly for agriculture. The main goal of the project is to establish input-output balances for some anthropologically induced and natural substances. A computer model is being developed and calibrated using field data. This model should be transferable to similar rural areas

The test sites were situated within 5-12 km of each other with almost identical climate conditions. 4 refs, 3 figs

The hydrochemistry of the observed groundwater was also investigated. 4 refs, 2 figs
