Regulatory limits are currently expressed as Aroclors, but factors may dictate that a site be evaluated based on the results of PCB congener analysis. The cost of HR-GC/MS analysis may be prohibitively high and may be inappropriate for initial investigations. As an alternative, ARI will offers Congener analysis using GC/ECD-8082 method. Tissue Analyses Mercury, PCBs, Chlordane, Dioxin or DDT have been the primary constituents responsible for fish consumption advisories in the past. Additional chemicals have the potential to cause adverse effects after release to surface waters due to bioaccumulation in aquatic organisms. In response, agencies are increasing efforts to monitor fish and shellfish contamination and to identify the cause and source of the contamination. ARI has years of experience analyzing Tissues for Butyl Tins, Aroclor PCBs, Chlorinated pesticides, Semivolatile Organics, Pentachlorophenol, Metals, Mercury and Lipids. New for 2006 are method specific clean-ups to reduce interferences from the matrices and addition of a large capacity grinder for homogenizing larger organisms.
