2. 1. Bioaugmentation for reduction of diffuse pesticide contamination : a bioprophylactic concept

   Author : Karin Önneby; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Pesticides and their residues frequently contaminate surface waters and groundwater so consequently there is a great need to identify methods and practices that reduce such contamination. This thesis examined the potential of a 'bioprophylactic' concept based on the hypothesis that diffuse contamination after application in the field can be significantly reduced if pesticides are degraded as rapidly as possible after the intended effect has been achieved.

4. 2. Bioaccumulation and biological effects of organic contaminants in Icelandic coastal waters

   Author : Halldóra Skarphéđinsdóttir; Åke Granmo; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Miljögifter; Marine Ecotoxicology; marin ekotoxikologi;

   Abstract : In this thesis, studies on organic contamination from both diffuse and point sources in Icelandic waters are presented. The aim was to investigate bioaccumulation and biological effects of the contaminants or biomarkers, and their applicability in environmental marine coastal monitoring, especially in areas with moderate or low levels of contamination such as Iceland.

   Abstract : Indoor air quality directly affects the comfort, performance, and well-being of occupants. Indoor pollution can cause immediate or long-term health effects and has been responsible for 4.1% of global deaths in recent decades. READ MORE

6. 4. Sources of pesticide losses to surface waters and groundwater at field and landscape scales

   Author : Anna Lindahl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Pesticide residues in groundwater and surface waters may harm aquatic ecosystems and result in a deterioration of drinking water quality. EU legislation and policy emphasize risk management and risk reduction for pesticides to ensure long-term, sustainable use of water across Europe. READ MORE

7. 5. Occupational skin exposure to cobalt : origin and fate

   Author : Jolinde Kettelarij; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Exposure to cobalt is not without risk. Besides adverse health effects on the respiratory system, cobalt is one of the most important sensitising metals with a contact allergy prevalence of 2.2% in the general population. Sources of exposure to cobalt in the general population are diffuse. READ MORE
