Polychlorinated naphthalenes (PCNs) are complex mixtures of the reaction products of chlorine with naphthalene. PCNS were previously used in electrical devices, and as additives to wood, paper and textiles to provide resistance against water, flame, insects, mold and fungi. PCNs have not been in commercial use since the 1980s but may be produced indirectly as a by-product of various industrial processes involving chlorine, especially in the presence of heat. Today PCNs are persistent, widespread, and bioaccumulative in the environment, and are regarded as an environmental problem.
- SGS AXYS offers analysis for the determination of up to 50 congeners of polychlorinated naphthalenes using GC-HRMS in aqueous (water/effluent), solid (soil/sediment/biosolids), tissue, and high volume and passive sampling (XAD-2, resin, SPMD, PED) matrices.
AXYS Supports Environment Canada’s Fish Contaminants Monitoring and Surveillance Program
Environment Canada’s (EC) Fish Contaminants Monitoring and Surveillance Program (FCMSP) began in 1977. The purpose of the program is to survey collectively, the concentration of contaminants in selected species of fish and other biota with the specific objective of determining environmental trends in contaminant levels and to relate these to sources of such pollution, the effectiveness of remedial actions, and the risk to fish and fish-consuming wildlife in aquatic ecosystems across Canada. The FCMSP provides data on the concentrations of contaminants of emerging concern, including PCNs, in the environment and their propensity to bioaccumulate to inform risk assessments under the Canadian Environmental Protection Act (CEPA) and from which to assess the effectiveness of regulations aimed at reducing the concentrations of contaminants in the environment.
