Aldehydes are carbonyl compounds found ubiquitously in the environment, derived from both natural and anthropogenic sources. As the aldehydes are reactive species, therefore, they are generally toxic to the body. To reduce the toxicity and pathogenesis related to aldehydes, the human body contains several aldehyde metabolizing enzyme systems including aldehyde oxidases, cytochrome P450 enzymes, aldo-ketoreductases, alcohol dehydrogenases, short-chain dehydrogenases/reductases and aldehyde dehydrogenases (ALDHs). These enzyme systems maintain a low level of aldehydes in the body by catalytically converting them into less-harmful and easily excreted products. The human ALDH (hALDH) superfamily consists of 20 functional ALDH genes identified so far at distinct chromosomal locations, expressing 20 ALDH proteins, which belong to 11 different ALDH families. They are involved in the NAD(P)+-dependent oxidation of a wide range of exogenous and endogenous aldehydes to their corresponding carboxylic acids. The hALDHs are present in all sub-cellular locations and have a wide tissue distribution. This review gives an account of aldehydes; their source, toxicity and metabolism, different aldehyde metabolizing enzymes with special emphasis on ALDHs including their biochemical, physiological and pathophysiological roles in the body.

Handbook of Environmental Health, Volume I: Biological, Chemical, and Physical Agents of Environmentally Related Disease

The second volume of the Third Edition of the Handbook of Environmental Health and Safety has been completely revised and expanded to reflect new developments and discoveries in environmental health and safety. Volume II provides environmental health professionals, environmental managers, safety professionals, and the public with a basis for understanding the interactions between humans and the environment and how such interactions affect the health and welfare of individuals. It includes a new chapter on instrumentation, state-of-the-art graphics, and a comprehensive index and bibliography.Completely new and significantly expanded and updated sections in Volume II of Handbook of Environmental Health and Safety include: o Global Warming - Potential Health Effects o Particle Retention and Deposition in Lungs o Major Sources of Hazardous Air Pollutants o Hazardous Air Pollution Control Devices o Clean Air Act of 1990 o Climate Change Action Plan o Landfill Gas into Electricity o Real Cost of Landfill Disposal o Materials-Handling Technologies o Reducing Toxic Risks through Voluntary Action o Metals and Disease o Ground Penetrating Radar o Hazardous Waste Innovative Technologies o Ground Water Contamination Sources o Latest National Primary Drinking Water Standards Available o New Microbiological Standards o Cryptosporidosis o Drastic Water Pollution Potential Mapping System o Ground Water Protection Programs o Ground Water Innovative Technologies o Soil Cleaning Innovative Technologies o Description of Parent Soils.Volume II focuses on major topics related to the external environment. It covers air quality and air pollution, solid and hazardous waste management, on-site and public water supplies, swimming areas, plumbing, on-site and public sewage disposal, soils, water pollution and water quality controls, disasters, and environmental health emergencies.
