Book Description
Sudden death among sewage workers is the most familiar form of hydrogen sulphide poisoning. This colorless, flammable gas has a characteristic odor of rotten eggs. It is produced naturally and as a result of human activity. Natural sources include nonspecific and anaerobic bacterial reduction of sulphates and sulphur-containing organic compounds. Hydrogen sulphide is found naturally in crude petroleum, natural gas, volcanic gases, and hot springs. It is also found in ground water. It is released from stagnant or polluted waters and manure or coal pits. In the industry, it is used as an intermediate in the manufacture of sulphuric acid and inorganic sulphides and as an agricultural disinfectant.--Publisher's description.

Book Description
On-board fires can occur on submarines after events such as collision or explosion. These fires expose crew members to toxic concentrations of combustion products such as ammonia, carbon monoxide, hydrogen chloride, and hydrogen sulfide. Exposure to these substances at high concentrations may cause toxic effects to the respiratory and central nervous system; leading possible to death. T protect crew members on disabled submarines, scientists at the U.S. Navy Health Research Center's Toxicology Detachment have proposed two exposure levels, called submarine escape action level (SEAL) 1 and SEAL 2, for each substance. SEAL 1 is the maximum concentration of a gas in a disabled submarine below which healthy submariners can be exposed for up to 10 days without encountering irreversible health effects while SEAL 2 the maximum concentration of a gas in below which healthy submariners can be exposed for up to 24 hours without experiencing irreversible health effects. SEAL 1 and SEAL 2 will not impair the functions of the respiratory system and central nervous system to the extent of impairing the ability of crew members in a disabled submarine to escape, be rescued, or perform specific tasks. Hoping to better protect the safety of submariners, the chief of the Bureau of Medicine and Surgery requested that the National Research Council (NRC) review the available toxicologic and epidemiologic data on eight gases that are likely to be produced in a disabled submarine and to evaluate independently the scientific validity of the Navy's proposed SEALs for those gases. The NRC assigned the task to the Committee on Toxicology's (COT's) Subcommittee on Submarine Escape Action Levels. The specific task of the subcommittee was to review the toxicologic, epidemiologic, and related data on ammonia, carbon monoxide, chlorine, hydrogen chloride, hydrogen cyanide, hydrogen sulfide, nitrogen dioxide, and sulfur dioxide in order to validate the Navy's proposed SEALs. The subcommittee also considered the implications of exposures at hyperbaric conditions and potential interactions between the eight gases. Review of Submarine Escape Action Levels for Selected Chemicals presents the subcommittee's findings after evaluation human data from experimental, occupational, and epidemiologic studies; data from accident reports; and experimental-animal data. The evaluations focused primarily on high-concentration inhalation exposure studies. The subcommittee's recommended SEALs are based solely on scientific data relevant to health effects. The report includes the recommendations for each gas as determined by the subcommittee as well as the Navy's original instructions for these substances.

Book Description
U.S. Navy personnel who work on submarines are in an enclosed and isolated environment for days or weeks at a time when at sea. Unlike a typical work environment, they are potentially exposed to air contaminants 24 hours a day. To protect workers from potential adverse health effects due to those conditions, the U.S. Navy has established exposure guidance levels for a number of contaminants. The Navy asked a subcommittee of the National Research Council (NRC) to review, and develop when necessary, exposure guidance levels for specific contaminants. This volume, the third in a series, recommends 1-hour and 24-hour emergency exposure guidance levels (EEGLs) and 90-day continuous exposure guidance levels (CEGLs) for acetaldehyde, hydrogen chloride, hydrogen fluoride, hydrogen sulfide, and propylene glycol dinitrate.

Book Description
Hazardous Gases: Risk Assessment on Environment and Human Health examines all relevant routes of exposure, inhalation, skin absorption and ingestion, and control measures of specifics hazardous gases resulting from workplace exposure from industrial processes, traffic fumes, and the degradation of waste materials and how they impacts the health and environment of workers. The book examines the risk assessment and effect of poisonous gases on the environment human health. It also covers necessary emergency guidelines, safety measures, physiological impact, hazard control measures, handling and storage of hazardous gases. Each chapter is formatted to include an introduction, historical background, physicochemical properties, physiological role discussing mechanisms of toxicity, its effect on human health as well as environment, followed by case studies and recent research on toxic gases. Hazardous Gases: Risk Assessment on Environment and Human Health is a helpful resource for academics and researchers in toxicology, occupational health and safety, and environmental sciences as well as those in the field who work to assess and mitigate the impact of toxic gases on the work environment and the health of the workforce. Emphasizes the environmental monitoring in the workplace of hazardous materials Includes all relevant storage and handling information required for detailing all personnel on the hazards and risks from the substances with which they work Offers practical examples and case studies related to toxic gases and their impact on health

Book Description
These new volumes of Methods in Enzymology (554 and 555) on Hydrogen Sulfide Signaling continue the legacy established by previous volumes on another gasotransmitter, nitric oxide (Methods in Enzymology volumes 359, 396, 440, and 441), with quality chapters authored by leaders in the field of hydrogen sulfide research. These volumes of Methods in Enzymology were designed as a compendium for hydrogen sulfide detection methods, the pharmacological activity of hydrogen sulfide donors, the redox biochemistry of hydrogen sulfide and its metabolism in mammalian tissues, the mechanisms inherent in hydrogen sulfide cell signaling and transcriptional pathways, and cell signaling in specific systems, such as cardiovascular and nervous system as well as its function in inflammatory responses. Two chapters are also devoted to hydrogen sulfide in plants and a newcomer, molecular hydrogen, its function as a novel antioxidant. Continues the legacy of this premier serial with quality chapters on hydrogen sulfide research authored by leaders in the field Covers conventional and new hydrogen sulfide detection methods Covers the pharmacological activity of hydrogen sulfide donors Contains chapters on important topics on hydrogen sulfide modulation of cell signaling and transcriptional pathways, and the the role of hydrogen sulfide in the cardiovascular and nervous systems and in inflammation
