Carbonaceous oxygen demand: Dilution with oxygen rich water, added an inhibitor (allylthioureum) to surpress nitrification. 5 days incubations. Measurement of oxygen before and after incubation. Chlorofyl a: Organic plant material is removed from the water by filtration over a glass fibre filter. Pigments are extracted from the algal cells with acetone 90% and then estimated spectrophotometrically at 750, 664/665, 645, 630 and 480 nm. Conductiviteit: in-field measurement with WTW multiparameter instrument Kjeldahl nitrogen: Segmented Flow Analyser (Skalar San) Nitraat (NO3-): Segmented Flow Analyser (Skalar San) Nitraat (NO3-): Segmented Flow Analyser (Skalar San) Nitriet (NO2-): Segmented Flow Analyser (Skalar San) Nitriet (NO2-): Segmented Flow Analyser (Skalar San) Opgelost silica: Inductively Coupled Plasma Emission Spectrophotometer (ICP-OES) from Thermo Scientific iCAP 6300 DUO. Opgeloste organische koolstof: Colorimetric with Skalar San+ Opgeloste zuurstof: in-field measurement with WTW multiparameter instrument Orthofosfaat: Segmented Flow Analyser (Skalar San) Phaeopigments: Organic plant material is removed from the water by filtration over a glass fibre filter. Pigments are extracted from the algal cells with acetone 90% and then estimated spectrophotometrically at 750, 664/665, 645, 630 and 480 nm. Phaeopigments: Organic plant material is removed from the water by filtration over a glass fibre filter.

Incenaration of filter for 4h at 550°C (LOI). Turbiditeit: in-field measurement with nephelometer Watertemperatuur: in-field measurement with WTW multiparameter instrument Zwevende stof: lab measurement by filtration of 3x50 ml on a Whatmann GF/F 0.7 µm filter Bijdrage door
