  1. 1. Pressurized Fluid Extraction A Sustainable Technique with Added Values

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Monica Waldebäck; Karin Markides; Åke Bergman; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; ASE; biomass; green chemistry; household waste; lipid; pesticide; PFE; pressurized fluid extraction; sediment; Analytisk kemi; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi;

    Abstract : The challenge for the future was defined by the Brundtland Commission (1987) and by the Rio Declaration (1992), in which the fundamental principles for achieving a sustainable development were provided. Sustainable chemistry can be defined as the contribution of chemistry to the implementation of the Rio Declaration. READ MORE

  3. 3. Acute pesticide poisonings in Nicaragua : Underreporting, incidence and determinants

    University dissertation from Stockholm : Karolinska Institutet, Department of Public Health Sciences

    Author : Marianela Corriols Molina; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pesticide poisonings; surveillance system; underreport; incidence; economic costs; determinants; integrated pest management;

    Abstract : Background: Acute pesticide poisonings (APP) are a public health problem in Nicaragua. The quality and coverage of APP´s register, the real incidence of APP, the main determinants, the economic cost of treating cases and the effectiveness of educational intervention are not well known.

  4. 4. Development of Enhanced Analytical Methodology in Pesticide Chemistry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tuija Pihlström; Karin E Markides; Bengt-Göran Österdahl; Amadeo Rodríguez Fernández-Alba; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : The analysis of pesticide residues in fruit, vegetables, rape seed and water has been improved using developments in sample handling and analytical techniques. The method development is associated with analytical difficulties, since pesticides currently used in agriculture represent a variety of chemical classes having very different physico chemical properties.

  5. 5. Ecological effects of pesticides in freshwater model ecosystems

    University dissertation from Lina Wendt-Rasch, Ecotoxicology, Ecologybuilding, Sölvegatan 37, Lund, Sweden

    Author : Lina Wendt-Rasch; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marine biology; aquatic ecology; limnology; Marinbiologi; Hydrobiology; community; zooplankton; algae; herbicide; insecticide; pesticide mixture; macrophytes; cypermethrin; metsulfuron-methyl; risk assessment; pesticides; microcosms; limnologi; akvatisk ekologi;

    Abstract : In this thesis I have investigated the effects of pesticide exposure on the ecosystem level using various types of experimental ecosystems, i.e. microcosms. The direct effect of exposure to cyperemthrin, a pyretroid insecticide, was a rapid decrease of crustancean zooplankton in enclosures in a lake. READ MORE
