1. 1. Qualitative Analysis of Chlorinated Paraffins in Recycled Plastics

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Solal GAUDIN; [2023]
   Keywords : Short chain Chlorinated Paraffins SCCP Medium chain Chlorinated Paraffins MCCP Long chain Chlorinated Paraffins LCCP Recycled plastics Qualitative analysis Bioaccumulation Long range transport Gas Chromatography – Mass spectrometry;

   Abstract : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. READ MORE

3. 2. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography

   University essay from Lunds universitet/Kemiska institutionen

   Author : Mohamad Abd Elwadood; [2023]
   Keywords : Analytical Chemistry; Fatty Acids; Gas Chromatography; Green Herbicides; Retention Index; Flame Ionization Detector; Mass Spectrometry; Supercritical Carbon Dioxide Extraction.; Chemistry;

   Abstract : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. READ MORE

4. 3. The application of low-cost sensors in estimates of greenhouse gases : A field study at a wastewater treatment plant

   University essay from Linköpings universitet/Filosofiska fakulteten; Linköpings universitet/Tema Miljöförändring

   Author : Daniel Montecinos; Saga Magnusson; [2022]
   Keywords : Methane; Carbon dioxide; wastewater treatment; Low-cost sensor network; Measurement; Environmental monitoring;

   Abstract : Anthropogenic activity has caused increased concentrations of greenhouse gases (GHGs) in the atmosphere which has resulted in global warming gaining momentum. GHG emission estimates up to date are insufficient and in order to mitigate GHG emissions of anthropogenic origin fluxes of GHGs need to be mapped. READ MORE

5. 4. Ethylene to Liquid Hydrocarbons by Heterogeneously Catalyzed Oligomerization on ZSM-5

   University essay from Uppsala universitet/Fysikalisk kemi

   Author : Gustav Halldén; [2022]
   Keywords : ethylene; ethane; oligomerization; catalyst; heterogeneous catalysis ZSM-5; zeolite;

   Abstract : The aim is to produce aliphatic liquid hydrocarbons using heterogeneous ethylene oligomerization. Thiscould potentially produce renewable synthetic fuels. Heterogeneous catalysis has some advantages overhomogeneous catalysis regarding some sustainability aspects. READ MORE

6. 5. Effects of plant-fungal interactions on volatile emission of Hordeum vulgare and aphid preference

   University essay from SLU/Dept. of Ecology

   Author : Bina Johansson; [2022]
   Keywords : volatile organic compounds; chemical communication; Trichoderma atroviride; Fusarium graminearum; Rhopalosiphum padi; biological control;

   Abstract : Barley is one of the most economically important cultivated crops in the world. However, barley is a host for many insect pests and plant pathogenic fungi which is a threat to the production. Rhopalosiphum padi is an economically important insect pest that leads to large economical losses in agricultural crops such as barley. READ MORE
