Environmental contaminants inventory study no. 4 : the production, use and distribution of phthalic acid esters in Canada / T.D. Leah. : En36-508/47E-PDF
"This study is the fourth in the Environmental Contaminants Inventory Series. The first chapter contains an introduction to and summary of the material detailed throughout the report. The second and third chapters review the literature on ortho-phthalic acid esters (PAEs) in the environment and their effects on human health. By combining information on exposure and toxicity, an attempt is made to assess the present hazard to human health and the environment posed by observed levels of PAEs in the environment. In the fourth chapter, the production and use of PAEs in Canada is analyzed for the year 1973. The fifth chapter covers the releases of PAEs to the environment from production and processing, and from the use and disposal of articles that contain PAEs. Estimates indicate that in 1973 releases from production and processing activities comprised approximately 20% of the total, whereas use and disposal activities accounted for the remaining 80%. These releases have been presented in terms of major drainage basins to give the data more regional significance. The sixth chapter reviews the chemistry and properties of PAEs, the major processes used in producing and fabricating flexibilized (plasticized) poly (vinyl chloride) and the use of related chemicals such as phthalic anhydride and terephthalic acid. The final chapter summarizes the conclusions and recommendations based on the findings of this study. Throughout the report, the data are clarified through the use of a material flow chart, tables, and maps"--Abstract, page vii.
