- Polychlorinated biphenyls (PCBs) as weli as dioxins, polychlorinated
dibenzo-p-dioxins (PCDDs) and -dibenzo-furans (PCDFs) are potentially hazardous
compounds in the environment. As in other industrialized countries, contamination of
breast milk with PCBs and dioxins (PCDDslPCDFs) in the Netherlands has led to
considerable public concern. The Dutch government launched a prospective follow-up
study in 1989 to investigate the potential adverse effects of environmental exposure to
PCBs and dioxins on growth and development of the human foetus and newborn. The
observation period was expanded until 4 2 months of age in an EC-funded collaborative
project entitled: 'Neonatal PCB exposure and neurodevelopmental deficit', financed by
the ENVIRONMENTAL and CLIMATE research programme, DGXII of the European
Commission, Contract-No EVSV-CT92-0207. The study was designed to look into a
spectrum of PCB-related effects in order to decide if neurological and cognitive
development are affected by perinatal exposure to PCBs and related compounds, and if
European background concentrations represent levels of concern. In this multi center
cohort study, our Dutch cohort, a German and a Danish cohort are included. The work
in this thesis describes the results from the Dutch cohort. In this prospective
longitudinal study, breast-fed and formula-fed infants were studied from birth until 42
months of age. Results on growth, health and development until 42 months of age are
presented.
