1. Reproductive toxicology of endocrine disruptors : effects of cadmium, phthalates and phytoestrogens on testicular steroidogenesis
Abstract : A number of investigations during the last two decades describe adverse trends in male reproductive health, which have been proposed to be caused by environmental factors with endocrine disrupting properties. In contrast to many other toxicants, endocrine disruptors often do not show linear dose-response relationships typical of those found in traditional toxicological studies. READ MORE

2. Arsenic Influences Virus Replication in Experimental Coxsackievirus B3 Infection
Abstract : Trace elements are essential for the host defence against infections, and during common infections, the balance of trace elements is changed in serum and tissues. Supplementation with selenium (Se), an essential trace element, is known to decrease the severity of coxsackievirus B3 (CVB3) infection in mice. READ MORE

3. Priority setting strategies for regulatory testing of industrial chemicals
Abstract : For the majority of the estimated 70,000 industrial chemical substances available on the European market today there is not enough information to enable a reasonably complete assessment of the risks that they might pose to man and the environment. Any strategy for the generation of additional data for these substances should aim at making testing as efficient as possible taking into account environmental and health protection, time, monetary cost and animal welfare.

5. Office work and physical factors : health aspects of electromagnetic fields and light
Abstract : The overall aim of this thesis is to increase our knowledge of the physical environment of office workers with special focus on electromagnetic fields and to address the question of whether electromagnetic fields can directly or indirectly contribute to symptoms or discomfort among video display terminal ( VDT) workers. Furthermore, we have measured light modulation from various commonly used light sources in laboratory conditions and, as a second step, used modulated light as stimulus for provocation of neurophysiological responses in persons with perceived “electrical hypersensitivity” (EHS).
