Semi Volatile Organic Compound Testing – over 100 reasons why you can’t go wrong!

Semi-volatile organic compounds (SVOC's) are a group of compounds that can lead to adverse effects on both animal and human health.  Exposure can arise from direct product use, the indoor environment and contaminated water sources.

Classes of SVOC's include:

  • Polyaromatic hydrocarbons (PAHs) – originate from by-products of petroleum processing or combustion;
  • Phenols - many uses such as chemical intermediates, plastics processing, wood preservatives, tanning agents, pesticides, antiseptics, antioxidants, pharmaceuticals, dyes and can also occur as disinfection by-products in water;
  • Phthalates - used as plasticisers in rubber and plastic materials;
  • Pesticides (organochlorine, organophosphate and triazines) – originate from agricultural run-off;
  • Anilines - used in the manufacture of industrial chemicals.

The AWQC has recently developed a NATA accredited analytical method based upon US EPA Method 8270 to detect and quantify over 100 SVOCs in extracts prepared from surface and ground waters, treated and raw waters and seawater samples. Table 1 lists the analytes that can be reported together with their associated limit of reporting (LOR) values.
