Sediment analysis
Sediment analysis in lakes or reservoirs permits a comparison to be made of present-day and historical water quality. This is of particular importance where water quality is considered to have deteriorated with time. AQUENS undertakes analysis of sediment cores to investigate pollution in lakes from nutrients, pesticides, trace metals, acid precipitation and hydrocarbons. Lake core sediments are dated by analysis of 135Cs and 210Pb isotopes to establish time horizons.
