1. 1. 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

3. 2. Tracing Characteristics of Two Water Hole Features with Multiproxy Analysis : Using Soil Chemistry, Archaeobotany and Entomology

   University essay from Umeå universitet/Institutionen för idé- och samhällsstudier

   Author : Johanna Kantak; [2023]
   Keywords : Water wells; Macrofossils; Soil chemistry; NiR; MS; XRF;

   Abstract : En omfattande multiproxyanalys har utförts på provtagningar från två vattenhål belägna i Skåneregionen i Sverige. Denna mångsidiga analys involverade flera aspekter, inklusive markkemi, entomologi, mikrofossiler och makrofossiler. Resultaten från markkemianalysen avslöjade betydande skillnader mellan de två vattenhålen. READ MORE

4. 3. Effects of soil factors on pioneer bryophyte species composition

   University essay from Lunds universitet/Examensarbeten i biologi

   Author : Dora Mijić; [2023]
   Keywords : Biology and Life Sciences;

   Abstract : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.

5. 4. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

   University essay from SLU/Dept. of Soil and Environment

   Author : Emma Ryding; [2022]
   Keywords : Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

   Abstract : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. READ MORE

6. 5. Long-Term Impact of Drought on AcidSulfate Soil Leaching, a Study of NineCatchment Areas in Sweden and Finland

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Emilie Åström; [2022]
   Keywords : acid sulfate soil; hydrological drought; water chemistry; metal leaching; sulfate concentration; sur sulfatjord; hydrologisk torka; vattenkemi; metallurlakning; sulfatkoncentration;

   Abstract : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. READ MORE
