WebSVOC Water Test. 71 Analytes Tested. See Full List. Recommended for targeted testing of semi-volatile organic compounds (SVOC) in drinking water. SVOCs are a broad group of moderate volatility substances that can be found in pesticides, plasticizers, flame retardants, furnishings, personal care products (PPCP), electronics, and cleaning agents. WebGenerally environmental analysis for SVOCs focuses on the extraction, identification and quantitation of contaminants.

WebPolycyclic aromatic hydrocarbons (PAHs) are a class of chemicals that occur naturally in coal, crude oil, and gasoline. They result from burning coal, oil, gas, wood, garbage, and tobacco. PAHs can bind to or form small particles in the air. High heat when cooking meat and other foods will form PAHs. WebSemi-volatile organic compounds (SVOCS) are chemically similar to other VOCs with carbon-based molecular structures but are present both as a gas and, to a substantial degree, sorbed (stuck) to indoor materials and the surfaces of airborne particles. Flame retardants, plasticizers, and pesticides are examples of the indoor sources of SVOCs. eashum and sons dover de
