8. PrecIsion and Accuracy 8 1 82 In a smgle laboratory (SEWL), usmg distIlled water standards at concentratIOns of 0 5, 10, 20, 50, 10 0 and 200 ug Hg/l, the standard deviations were ±O04, ±O07, ±O09, ±O20, ±O40and ±O84ug/l,respectively In a smgle laboratory (SEWL), usmg surface water samples spiked with ten orgamc mercunals at the 10 ug/l level, recovenes ranged from 87 to 117% Recovenes of the same ten orgamc mercunals m distIlled water at the 10 ug/llevel, ranged from 92% to 125% Blbhography 1 Wallace,R A,Fulkerson,W ,Shults,W D,andLyon,W S,"MercurymtheEnVlfonment- The Human Element", Oak Ridge NatIOnal Laboratory, ORNL-NSF-EP-l, p 31, (January, 1971) 2 Hatch, W R and Ott, W L , "Determmatlon of Sub-Microgram QuantIties of Mercury by Atomic AbsorptIOn Spectrophotometry", Anal Chem 40,2085 (1968) 3 Brandenberger, H and Bader, H , "The Determmatlon of Nanogram Levels of Mercury m Solution by a Flameless AtomiC Absorption Techmque", AtomiC AbsorptIOn Newsletter ~ 101 (1967) 4 Brandenberger, H and Bader, H, "The DetermmatlOn of Mercury by Flameless AtomiC Absorption II, A Static Vapor Method", Atomtc Absorption Newsletter1.-53 (1968) 5.
