Methods usedwere as follows: LC/MS/MS - PFOA; GC/MS - all others.Values were obtained by measuring individual products, obtaining the impurity levels in ppm, and then calculating the actual pounds of impurities bymultiplying the pounds made times the ppm of impurities. These are the values reported above. If a value was determined to be <LOQ, we used thestandard EPA convention of 1/2 LOQ as the measurement for the yearly pounds calculation.
