Lakes; Chemistry

Updated 2017-10-13

Annual measurements of physical, chemical, and biological variables are taken in small to medium sized, mostly minimally disturbed lakes, situated across the country. Of the 108 lakes that are part of the Trend Station Lake monitoring programme, 20 are situated in AMAP area. The main aim of the monitoring programme is to document long-term changes related to global or regional change and human-generated stressors. To complement the Trend Station Lake monitoring programme, national lake surveys provide spatial data needed to determine regional patterns, and coupled with time-series data, changes in surface water quality. The National Lake Survey (the Surveillance Stations, re-sampled stations) programme for lake water quality, started in 2007 and results in data of all Swedish lake conditions. Each year some 800 new lakes are sampled to determine chemical and physical conditions; lakes are resampled at 6 year intevals. 4824 lakes are sampled in the country during a six-year sampling cycle, with 1270 situated in AMAP area. The variables included in the Trend Station Lake monitoring programme include water chemistry, fish, phytoplankton, macrophytes, zooplankton, and benthic invertebrates, whilst the National Lake Survey is focused solely on chemical and physical parameters.

This is a National Implementation Plan (NIP) project
Comments and additional information:

Comments and additional information on the National Lake Survey: The network is based on EMEP-squares and gives between 19 and 134 lakes sampled per county every year. Sampling at 0.5 - 2.0 m depth during fall circulation. Temperature, pH, NH4, NO2-NO3, Tot-N, Tot-P, PO4, TOC, Si, Absorbance (four wave lengths), Turbidity, Fe, Mn, Alkalinity, Ca, Mg, K, Na, SO4, Cl, F, and trace metals Cu, Cd, Pb, Cr, Ni, Co, Ni, V, Al are analysed.
