Semi-volatile pollutants group consists of compounds with broad chemical and structural properties. Examples of semi-volatile compounds include hydrocarbons, aldehydes, ethers, phenols, organic acids, ketones, amines, amides, nitroaromatics, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), phthalate esters, and nitrosamines.
Sources of these compounds include pesticides and herbicides (containing phosphorus, sulfur, chlorine or nitrogen), flame retardants, ingredients in cleaning agents and personal care products, solvents and chemicals used in textile and electronics manufacturing, and materials manufacturing process additives.
Air, water, soil and biota tests are performed in advanced laboratories to monitor the presence and concentrations of pollutants present. Due to the tendency of pollutants to accumulate, concentrate and persist in these natural matrices, these matrices are analyzed to provide information that will help limit the spread of pollution and its impact on environmental health. In general, environmental analysis for semi-volatile organic compounds (SVOC) focuses on the extraction, identification and quantification of pollutants.
In short, volatile organic compounds, sometimes polycyclic aromatic hydrocarbons, are chemicals consisting of hydrogen and carbon that evaporate at room temperature. This process, known as degassing, releases harmful chemicals into the air and has a dramatic effect on indoor air quality as these chemicals are found in a wide variety of consumer products. Because volatile organic compounds pose both health and environmental protection risks, different governing bodies publish standards and guidelines to understand what healthy VOC concentrations are and how to avoid overexposure.
Another major source of semi-volatile organic compounds is flame retardants. Polychlorinated biphenyls are the most common chemicals used in fire extinguishers and other devices for extinguishing flames.
It is impossible to completely avoid SVOCs. They are found in many popular products and because they evaporate at room temperature, their discharge into the air is nearly impossible to control. However, knowing where volatile organic compounds come from and the relevant safety standards can help ensure good indoor air quality and reduce the risk of developing health problems from these chemicals.
Our organization also provides semi-volatile organic compounds (SVOC) analysis services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
