Monthly water chemistry from 12 catchment areas
The analysis includes 23 parameters since mid-2010: pH, alkalinity, conductivity, two different absorbance values, suspended material content, turbidity (from mid-2010 to 2014), total organic carbon, total nitrogen, ammonium, nitrite nitrate, total phosphorus, phosphate phosphorus, sulphate, chlorine, fluorine, calcium, magnesium, sodium, potassium, iron, manganese, silicon, aluminium
Water chemistry from extended sampling after fertilization
Water sampling is additionally extended after every fertilisation in all catchment areas affected by the fertilisation and also in two control areas. After fertilisation water is sampled every- or every second day after fertilisation (4-5 times) and also during the coming summer at high water flow.
Water chemistry data from extended sampling after fertilizations includes: total nitrogen, ammonium, nitrite nitrate, phosphate phosphorus, total phosphorus.
Extended sampling in 2014 within the FutMon project
Water sampling from our two reference catchment areas took place twice a month.
Monthly water analysis from our two reference catchment areas included the following heavy metals: arsenic, cadmium, cobalt, chromium, nickel, copper, lead, vanadium, zinc, uranium, methylmercury (IVL), total mercury (IVL).
Mercury was analysed by Swedish Environmental Research Institute (IVL), read more about analysis methods, accreditation, measurement range and uncertainty etc. here
