Abstracts: ISEE 22nd Annual Conference, Seoul, Korea, 28 August–1 September 2010: Maternal Exposure to Persistent Toxic Substances and Pregnancy Outcomes in the Asia-Pacific Region
Maternal Exposure to Persistent Toxic Substances and Pregnancy Outcomes in the Asia-Pacific Region. The North-South Dimension. Introductory to the Symposium
Globally, a number of persistent toxic substances (PTS), including metals, are recognized as being responsible for adverse neurological development and other health effects in children. The growing fetus and newborn child are especially sensitive to the toxic effects of many persistent organic pollutants and heavy metals found in the environment. The levels of these contaminants in maternal blood during pregnancy give an indication of the potential risk to the developing fetus. Considerable efforts have been made over the last 30 years to characterize PTS concentrations in the environment in the Northern Hemisphere. Most of the research has focused on the DDT group, the PCB-group, industrial chemicals, and by-products such as dioxins and furans. Heavy metals such as mercury and lead have also been monitored in the environment and in a range of biota. More recently, the brominated flame retardants have been found in increasing concentrations in the environment and are considered the “new” or emerging PTS.
There is so far very limited information relating to the Asia-Pacific Region. The Arctic Monitoring and Assessment Programme (AMAP) initiated collaborative research programmes in a range of developed and developing countries in the Southern and Northern Hemisphere. The protocols for these studies are developed through the AMAP network, including the quality assurance/quality control of the laboratory performance in all study bases. This cooperation allows a direct comparison of results and assessments. Attention is now being given to the Asia-Pacific Region including Australia.
The aim of this symposium is to share current results of studies of maternal exposure and pregnancy outcomes from AMAP participants including Australia, Vietnam, and Russia.
The introductory presentation will outline the frame and context for the results presented in the symposium, including an overview of new Arctic cohorts.© 2011 Lippincott Williams & Wilkins, Inc.
