  2. 1. Development of GC-HRMS procedures for determination of naturally occuring polar compounds in various environmental applications

    Author : Bodil Widell; Dag Broman; Caroline Leck; Joan Grimalt; Stockholms universitet; []
    Keywords : GC-HRMS; steroid hormones; amino acids; perch; size-resolved aerosol; Arctic; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The overall objectives of this dissertation were to gain further understanding of the two following environmentally significant issues: (i) Determination of natural steroid hormones in blood plasma from perch (Perca fluviatilis) during a reproductive cycle and to evaluate the possibility of using the steroid composition as a biomarker for early signs of endocrine disruptive effects. (ii) Determination of dissolved free amino acids in size resolved airborne particles collected over the Arctic pack ice area (>80°N) in summer and to study their overall relationship with the ocean surface microlayer as a potential source.

  4. 2. Idiopathic environmental intolerance attributed to electromagnetic fields : physiological and psychological aspects

    Author : Amanda Johansson; Lena Hillert; Umeå universitet; []
    Keywords : electrical hypersensitivity; EHS; mobile phone; MP; heart rate variability; HRV; provocation study; radiofrequency field; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : This thesis aims to increase the knowledge on people with symptoms attributed to electromagnetic fields (EMF) by investigating the effects of EMF exposure and by additional description of the heterogeneous group of people reporting EMF-related symptoms. The effect of mobile phone (MP)-like radio frequency (RF) fields on symptoms, autonomic nervous system (ANS) parameters, short-term memory, and reaction time in persons with MP-related symptoms (MP participants) was investigated in a provocation study.
