HENVINET. Evaluation questionnaire - traffic pollution and environmental health.

The HENVINET consortium has developed a questionnaire to identify knowledge gaps in the state of the art in scientific knowledge. Literature reviews covered all elements that compose the causal chain of the different environmental health issues from emissions to exposures, to effects and to health impacts. Ultimately, the aim is to discuss the implications of these for policy and research. In this evaluation we focus on various aspects of the cause-effect relationship between traffic related air pollutants in ambient air and induction (incidence) of asthma and sensitization to allergens. The questionnaire consists of two separate parts. In Part A, you will be asked to comment on the completeness and structure of the causal diagram illustrating scientists\' current understanding of the cause-effect relationship. In Part B, you will be asked to express your confidence in scientists\' ability to predict the magnitude of a variety of proposed or potential associations.
