Natural circumstances, but also the extraction of raw materials, can lead to the accumulation of harmful elements in plants. For the further use of plant components as food or feed or as building materials, there are therefore limits that must be checked for compliance. Our investigations focus on the contamination of plant material with copper, lead, and zinc. We have carried out LIBS measurements on contaminated plant material using various lasers with pulse lengths in the ns and fs range ...Natural circumstances, but also the extraction of raw materials, can lead to the accumulation of harmful elements in plants. For the further use of plant components as food or feed or as building materials, there are therefore limits that must be checked for compliance. Our investigations focus on the contamination of plant material with copper, lead, and zinc. We have carried out LIBS measurements on contaminated plant material using various lasers with pulse lengths in the ns and fs range and with various spectrometers. Mapping techniques [1] allow us the spatially resolved determination of the contamination of plant material. The latest results will be presented.» weiterlesen» einklappen
