1. 1. Association of hydrophobic organic contaminants to size fraction of natural humic substances : using ultrafiltration and high-performance liquid chromatography

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Kristina Tattersdill; [2011]
   Keywords : humic substance; high-performance size exclusion chromatography; ultrafiltration; pesticide; size fraction;

   Abstract : Ultrafiltration and high-performance size exclusion chromatography (HPSEC) were used to determine interactions between different size-fractions of natural humic substance and carbofuran, lindane, chlorpyrifos and PCB-105. Ultrafiltration, using filter MWCO size of 1 kDa and 100 kDa, showed an adsorption of pesticide to filter. READ MORE

3. 2. Atmospheric Deposition of Legacy and Emerging Persistent Organic Pollutants in Northern Sweden

   University essay from Kemiska institutionen

   Author : Seth Newton; [2011]
   Keywords : ;

   Abstract : Bulk atmospheric deposition samples using Amberlite IRA- 743 as an absorbent for hydrophobic pollutants were taken every two months for one year at two different locations in northern Sweden. A method was developed for the analysis of various legacy and emerging POPs in these samples based on GC-HRMS. READ MORE

4. 3. Multiple pesticide stressors and ecosystem functioning in stream detrital food webs

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Mohab Dawoud; [2011]
   Keywords : Stream ecosystem; decomposition process; leaf litter; Lindane; Azoxystrobin; Asellus aquaticus; aquatic microorganism;

   Abstract : Streams and rivers are highly susceptible to environmental degradation from agricultural activities, including the clearance of riparian vegetation and the runoff of chemical fertilizers and pesticides. These impacts are likely to increase in the future as agricultural practices intensify to meet the needs of an expanding human population. READ MORE

5. 4. Water and pollutant flows through the Mejdurechye Reservoir, Uzbekistan

   University essay from Institutionen för naturgeografi och kvartärgeologi (INK)

   Keywords : Central Asia; Uzbekistan; hydrology; Amudarya; Mejdurechye; water; water reservoir; pollutant;

   Abstract : Karakalpakstan, Uzbekistan, has faced water scarcity and low water during several years as a consequence of Uzbekistan’s extensive irrigation of cotton fields. The environmental status of the Mejdurechye Reservoir, which is the largest in the lower Amudarya Delta, is therefore of great local importance. READ MORE

6. 5. Analysis of some Chlorinated Pesticides in Jordanian Ground- and Surface Waters by Solid-Phase Extraction and Mass Spectrometric Detection- A Method development

   University essay from Tema vatten i natur och samhälle

   Author : Lara Shahin; [2004]
   Keywords : Ecology; Decomposition; Jordan; pesticides; PS-DVB; SPE; Ekologi;

   Abstract : A solid-phase extraction (SPE) method was developed for the determination of organochlorine pesticides, namely aldrin, alpha-BHC, beta-BHC, delta-BHC, dieldrin, endosulfan I, endosulfan II, endosulfan sulfate, endrin, endrin aldehyde, lindane, heptachlor, heptachlor epoxide, 4,4’-DDD, 4,4’-DDE and 4,4’- DDT in water. The effect of extraction conditions, such as the addition of sodium chloride and methanol to the sample prior to loading was studied. READ MORE
