CeFH lunch seminar: Effects of dioxins and DL-PCBs on semen quality

Presentation by Helle Katrine Knutsen, Norwegian Institute of Public Health

About the CeFH lunch seminars

Our lunch seminars are informal research seminars that are held normally every Friday. Both researchers at the Centre and researchers from all over the world present interesting topics in fertility and health. The presentations include new research ideas, projects, results and methods as well as possible collaborative projects.

Although primarily aimed at researchers at the Centre, the seminars are also open to other researchers at the Norwegian Institute of Public Health.

Please contact Fredrik Swift if you have questions about the seminar or if you would like to give a presentation

Effects of dioxins and DL-PCBs on semen quality –  basis for the new, lower tolerable weekly intake set by the European Food Safety Authority (EFSA).

Helle Katrine Knutsen is toxicologist and scientist at the Norwegian Institute of Public Health (Department of Environmental Exposure and Epidemiology). She has a master in cell biology (UiO), and graduated in 1995 from the Institute of Medical Biochemistry (UiO) on a project on gene regulation in rat Sertoli cells. After a post.doc period at the same institute, she started at NIPH in 1999. Here she soon became involved in exposure to environmental toxicants, biomarkers of exposure and association with health outcomes in MoBa. Helle also engaged in health risk assessments in both VKM and EFSA, and is presently member of EFSA’s Nutrition Panel and chair of VKM’s panel on contaminants in the food chain.  Before that she was member of EFSA’s Panel on Contaminants (CONTAM) for nine years (Panel Chair for three years), and was heavily involved in the risk assessment on dioxins and DL-PCBs.

Helle will present the risk assessment on dioxins and DL-PCBs, with emphasis on the experimental animal and epidemiological data linking exposure to dioxins and DL-PCBs to reduction is semen quality. Even though the exposure has declined more than 80% the last decades, the current exposure in Norway is higher than the new tolerable weekly intake. This may be relevant to address further in MoBa.
