The Policy Interpretation Network on Children's Health and Environment (PINCHE) was a thematic network funded for three years by the European Union. PINCHE's main objective was to produce policy recommendations, based on published scientific research findings, aimed at protecting children's health and the environment. The project focused on four themes: indoor and outdoor air pollutants, carcinogens, neurotoxins, and noise. International scientific literature was selected using the PubMed, Embase, and Toxline databases. An evaluation system was developed to extract key information from each article and incorporate it into an evaluation form. The selected studies were evaluated based on quality criteria and scored. An interpretation grid was developed to analyze the information contained in the research results. The various PINCHE partners did not reach a unanimous consensus on whether it was feasible, or even desirable, to set priorities for children’s health in Europe. However, once this debate was resolved, the information contained in the grid allowed the partners to prioritize the various factors studied based on the urgency of reducing exposures. Outdoor air pollutants, environmental tobacco smoke, allergens, and mercury were classified as high priority. The main discussions concerned the priority to be given to flame retardants, lead, PCBs and dioxins, ionizing radiation, and certain noise sources. The priority list should be revised as new information becomes available. In all circumstances, the precautionary principle must apply, and exposure levels low enough to be safe for children must be targeted. (R.A.)
