This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.

Presents accounts of current research in polynuclear aromatic compounds, showing examples of studies both of pure compounds and of complex, fossil fuel related mixtures. Offers a thorough knowledge of aromatic chemistry through coverage of reduction, oxidation, and thermal reactions--including applications developed for both coal and petroleum materials. Featured topics include quantum chemical structure-reactivity relationships, spatial configurations of large polynuclear hydrocarbons, cyclophanes, and desulfurization of heterocycles. Scientists studying all aspects of the chemistry of polynuclear aromatics will discover important, pertinent information in this volume.

This 1991 volume was the first to review the chemical properties of the carcinogenic polycyclic aromatic hydrocarbons.

Analytical Chemistry of Polycyclic Aromatic Compounds focuses on the chemical and physical properties of the polycyclic aromatic compounds, critically evaluating various chromatographic and spectroscopic methods. This book discusses how gas chromatography and high-performance liquid chromatography can be both competitive and complementary analytical methods. Ancillary techniques of both are emphasized for the structural elucidation of individual polycyclic aromatic compounds in complex mixtures. The merits of spectroscopic methods in both structural work and quantitation are also described. This text likewise provides background information concerning the chemistry, occurrence, and toxicology of polycyclic aromatic compounds, including the isolation of polycyclic aromatic compounds from a wide variety of materials and matrices. This publication is recommended to scientists involved with the study of polycyclic aromatic compounds, analysts who need to acquire routine data, and individuals charged with formulating environmental policies and drafting regulations.

Symposium with over one hundred presentations was highlighted by overviews of the complex nature of PAH and their interaction with the environment and the human population that must live within it. New approaches and techniques for measuring PAH were discussed as were the fate of these compounds in the environment. Papers were presented defining the altered biological responses that were induced by PAH species. In some cases the newly defined, substituted PAH had greater effects than the parent compound. Several reports concentrated on the synthesis of derivative PAH species and the actual formation processes that occur in the combustion of fossil fuels.
