I en ny rapport från SLU Centrum för kemiska bekämpningsmedel i miljön utvärderas data från den biologiska övervakning som utförs i fyra vattendrag i södra Sverige. I rapporten diskuteras också

Organic environmental chemistry (OMK) laboratory develops methods and performs analyses of mainly pesticides (plant protection products, both currently used and banned) in different matrices such as

Below are the accredited analytical methods and their measurement uncertainties listed, since November 2017. For information about earlier analytical methods from 1960s and onwards, see each method .

The laboratory are analysing the chemical composition of inland waters. We are since 1992 accredited by SWEDAC for the analyses of about 40 different parameters, as well as for sampling. In total,

Closely related analytical methods that also estimate the amount of particles in the water are turbidity and the difference between absorbance on unfiltered and filtered water. Known issues in the

Alkalinity is measured by titration to pH 5.6, pH 5.4 or 4.5 with HCl. The CO 2 formed is continously removed by nitrogen gas flow-through. The endpoint is indicated with a pH electrode. Known issues

Known issues in the databases Presently, the acidity of the water is given as negative alkalinity in our databases. Current method of measurement Acidity is measured by titration to pH 5.6 with NaOH

Report (in Swedish) about method comparison while changing to the Gallery instrument (Metodjämförelse vid byte till Gallery) . Samples with a concentration below the reporting limit of the Gallery

Aluminium can be analysed with several different methods. Read more in our method comparison (in Swedish) . Known issues in the databases The metal analyses are now made of acidified unfiltered water

Absorbance in water The light permeability of water depends on the presence of suspended particles and dissolved substances in the water. In a filtered water sample, it is chiefly the light

I work at the department of aquatic sciences and assessment and the centre for chemical pesticides (CKB) with interpretation of monitoring data for plant protection products.  I also work with the
