1. 1. Detecting Pollutants Using Vibrations : Laser Doppler Vibrometry as a Non-Invasive Soil Organism Health Monitoring Method

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Kristoffer Wilson; [2023]
   Nyckelord :Vibrometer; Biotremology; Imidacloprid; Ants;

   Sammanfattning : Due to a lack of in-situ methods capable of detecting sub-lethal effects of pollutants on soil organisms, many polluted environments are not identified prior to pollution-induced changes in the soil fauna. Therefore, there is a need to develop new non-invasive methods to measure the health of soil organisms. LÄS MER

3. 2. Generell metod för analys av pesticider med HS-SPME i kombination med GC-MS : Möjligheten att identifiera pesticider i känd lösning och i förgiftningsfall

   Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Samuel Eliasson Heino; [2022]
   Nyckelord :Gas chromatography-mass spectrometry; Pesticides; Intoxication; Limit of detection; headspace-SPME; EPA 8151; Detection; Derivatization; Separation;

   Sammanfattning : This study focuses on a general method that has been developed for the identification of both polar- and nonpolar pesticidespolar pesticides in a known solution from EPA 8151 Herbicide acid mix by Merck including the ordered non-polar pesticide Prosulfocarb. The EPA-solution contains 16 analytes that has been completely identified when derivatized and spiked in acetone. LÄS MER

4. 3. Bedömning av faror som bekämpningsmedel utgör för Degebergas dricksvattentäkt - Perspektiv utifrån nuvarande markanvändning och vid en potentiell förändring

   Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

   Författare :Daniel Andersson; [2020]
   Nyckelord :Grundvatten; farobedömning; markkartering; pesticider; Earth and Environmental Sciences;

   Sammanfattning : Pesticides poses a threat to drinking water, especially where the usage is extended, like in Scania, Sweden. The main objective of this study was to identify and characterize substances used in the cultivated area of Degeberga. LÄS MER

5. 4. Insect Event Extraction in LIDAR Images using Image Analysis and Convolutional Neural Networks

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Ludvig Malmros; [2018]
   Nyckelord :Image analysis; Machine Learning; Mathematics and Statistics;

   Sammanfattning : Insect monitoring has earlier been a manual, tedious and time consuming task that is impossible to do in real time. Thus there exists a need for a real time automatic insect monitoring system for counting and classifying insect for use in scientific research and pesticide spraying control. LÄS MER

7. 5. Bekämpningsmedelsläckage från grundvatten till ytvatten - Undersökning av ett avrinningsområde i södra Skåne

   Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

   Författare :Ellen Jönsson; [2017]
   Nyckelord :legacy pesticides; pesticide fate; pesticide contamination; groundwater - surface water interaction; pesticide monitoring; groundwater contamination; stream water contamination; stream pollution; groundwater pollution; groundwater outflow.; Agriculture and Food Sciences; Earth and Environmental Sciences;

   Sammanfattning : From a small stream draining an agricultural catchment area in south Sweden, a temporal analysis of the occurrence of legacy pesticides was carried out and correlated with contemporary groundwater levelling, precipitation and flow rate of the stream, in order to evaluate groundwater outflow as an entry route for pesticides in the stream. Based on continuous measurement data from two periods of 12 respectively 16 months, in total eight legacy pesticides and three metabolites of legacy pesticides, were detected from early spring to late autumn, when runoff water to the stream was low and groundwater constituted the main water source of the stream.
