Volatile organic compounds released from Microcystis flos-aquae under nitrogen sources and their toxic effects on Chlorella vulgaris. To determine whether a mixture of VOGs could impair lung function or cause airway inflammation among subjects without bronchial hyper responsiveness, the authors conducted a randomized, crossover-design trial of controlled human exposures to filtered air for four … Certain organic compounds in environmental tobacco smoke (ETS) can cause respiratory diseases and lung cancers. Ozone is a key component of smog. Share. Volatile organic compounds contribute to environmental issues like smog. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. The behavior and health effects of ETS will depend upon how each of these compounds is distributed between the gas and the particulate phases. Abstract. A wide range of carbon-based molecules, such as aldehydes, ketones, and hydrocarbons are VOC's. Environmental Effects of Volatile Organic Compounds on Ozone Layer Omar Mohammed Said Ismaila,b, Reda. Different VOCs have different health effects, and range from those TVOC is a grouping of a wide range of organic chemical compounds to simplify reporting when these are present in ambient air or emissions. Headaches. Volatile organic compounds are partly of natural origin, partly contained in articles of daily use, and can constantly reach our nose and skin. Cite. The term often is used in a legal or regulatory context and in such cases the precise definition is a matter of law. Increasingly, however, the vaporous effects of volatile organic compounds are recognized as actually being absorbed through the skin, leading to further complications. Dizziness. When sunlight and heat react with VOCs, sulfur dioxide, and nitrogen oxides (gasses released from many industrial processes and vehicles) ozone is generated, and smog is formed. The U.S. Environmental Protection Agency (EPA) estimates that VOCs are present in one-fifth of the nation’s water supplies. Methods: Total volatile organic compounds, formaldehyde, nitrogen dioxide, damp (on a four category scale of % wood moisture equivalent), and environmental tobacco smoke (from salivary cotinine) were measured objectively in the homes of 193 children with persistent wheezing illness and 223 controls aged 9–11 years in Nottingham, UK. The Effects of VOC Exposure. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Health effects of volatile organic com-pounds in indoor air.
