I would like to submit the Samet, Jonathan M, " Traffic, Air Pollution, and health", Inhalation toxicology,19:12, 1021=1027 to indicate that the transportation conformity regulations do not provide adequate protections to children from environmental health and safety risks under Executive order 13045. Samet, Jonathan M. (2007) 'Traffic, Air Pollution, and Health', Inhalation Toxicology, 19:12, 1021 - 1027 "An enlarging body of research evidence indicates that exposure to traffic-related air pollution adversely affects health. The relevant evidence includes monitoring data on the characteristics of near-roadway pollution, the penetration of traffic-generated particles indoors, and the existence of hot spots of pollution in heavily trafficked areas. Epidemiological studies have linked indicators of exposure to traffic to adverse health effects, although the particular pollutants mediating these effects are still not identified. Additionally, difficult methodological issues call for caution in interpreting the epidemiological findings; there is potential for uncontrolled confounding, exposure measures are subject to misclassification, and uncertainty is not fully accounted for. Nonetheless, the evidence raises concern about a threat to public health that will be managed with great difficulty. Exposures to traffic reflect the amount of traffic and the coupling of emissions from traffic to pollutant concentrations in the environments where people spend time. Control will require both reduced emissions and increased separation of people from emissions. There is a need for further research to refine our understanding of the health consequences of traffic exposures and as a basis for formulating mitigation policies. While we continue to obtain further evidence, prudent, ?no-regret? strategies to reduce exposures merit consideration."
