Chemistry and environmental analysis

Since 2014, students have been offered the opportunity to work on projects within the framework of the LfU's Monitoring of Seepage Water Accompanying Measures. At the permanent monitoring centre in Triesdorf, the aim is to create an improved data basis for monitoring the effectiveness of agricultural measures on nitrate inputs into groundwater.

The extensive equipment of the analytical laboratory enables the processing of a wide range of environmentally relevant topics. Various chromatographic and spectroscopic analytical methods can be used.

In recent years, projects have been carried out on the following topics, among others:

• Determination of soluble, plant-available and total phosphorus as well as heavy metals in sewage sludge ash with and without prior MAP precipitation.
• Determination of antimony in electrical scrap by means of hydride AAS
• Development of a sample preparation of difficult matrices by dialysis for subsequent ion chromatography
• Optimisation of the extraction of chromium-VI from ash according to DIN EN 15192: 2006(D)
• Cadmium determination in environmental samples using graphite furnace AAS
• Comparison of methods for nitrate determination in soil samples using photometry, colorimetry or dialysis and subsequent ion chromatography
• Optimisation of a determination method for selenium in milk samples after digestion and measurement by means of hydride AAS
• Optimisation of a laboratory method for the determination of CAL-soluble phosphorus and potassium in soil and digestate samples

• Training as a chemical-technical assistant

• Studied chemistry, specialising in food chemistry and environmental analysis

• Employment at the State Investigation Office for Public Health in Northern Bavaria in Erlangen, in the area of veterinary drug residues and investigations according to the Meat Hygiene Ordinance

2023

• Investigation of soil contamination with per- and polyfluorinated alkyl compounds (PFAS) in the Berchtesgaden National Park, with special reference to atmospheric transport.
• Determination of fluorine as a sum parameter using high-resolution continuum source molecular absorption spectrometry (HR-CA-MAS)

2022

• Depth distribution of nitrate in arable land at the seepage monitoring station in Triesdorf

2021

• Determination of plant-available phosphorus in sewage sludge ash from mono-incineration (2016)

• Sediment and habitat investigation of stormwater retention ponds (2015)

• Development of a method for the investigation of CHC by headspace gas chromatography (2015)

• Degradation and retention capacity of the individual treatment stages of a constructed wetland (2014)
