Evaluates the carcinogenic risk to humans posed by exposure to selected Polynuclear Aromatic Compounds, Part 4, Bitumens, Coal-Tars and Derived Products, Shale-Oils and Soots.
An evaluation of the health effects and other relevant data since pub. of the 1977 NIOSH "Criteria for a Recommended Standard: Occupational Exposure to Asphalt Fumes." Includes an assessment of chemistry, health, and exposure data from studies in animals and humans exposed to raw asphalt, paving and roofing asphalt fume condensates, and asphalt-based paints. Will serve as to identify future research to reduce occupational exposures to asphalt. Chapters: no. of workers potentially exposed; physical and chemical properties; exposure; human health effects; experimental studies; research needs; uses and applications; summary of occupational exposure data; and respirators.
This book details three main topics: the screening and characterization of hydrocarbons from air, soil and water; technologies in the biodegradation of hydrocarbons; and the bioconversion of hydrocarbons for biofuel/chemicals, as well as recent developments in the remediation of hydrocarbons and their environmental benefits. The first section focuses on screening methods, qualitative and quantitative analysis of hydrocarbons from soil, air and water environments, speciation of hydrocarbons, and natural bioremediation strategies in such environments. The second section examines technologies for removing hydrocarbon contaminants from various environments, especially advanced technologies for the removal of hydrocarbons and in-situ and ex-situ remediation strategies and problems, as well as concrete case studies. The last section, covering the bioconversion of hydrocarbons for biofuel/chemicals, highlights the biochemicals and bioproducts developed from hydrocarbons, with a particular focus on biochemical and chemical technologies used to produce biopolymers, biofuel precursors and commodity chemicals from hydrocarbons.
The third in a series of congressionally mandated reports on Gulf War veterans' health, this volume evaluates the long-term, human health effects associated with exposure to selected environmental agents, pollutants, and synthetic chemical compounds believed to have been present during the Gulf War. The committee specifically evaluated the literature on hydrogen sulfide, combustion products, hydrazine and red fuming nitric acid. Both the epidemiologic and toxicologic literature were reviewed.
