Description In 2005, Ecology staff at the Manchester Environmental Laboratory adopted new methodology for determining mercury in fish tissue. Lab duplicates were analyzed using EPA Methods 245.5 and 245.6 to determine if laboratory methods affected analytical results.

A regression analysis of the lab duplicates found EPA Method 245.5 to report mercury concentrations 25-38% lower than Method 245.6, varying with magnitude of concentration. A correctional equation was developed to estimate mercury concentrations between methods.
