Decreased Accumulation of Phthalate Plasticizer during Storage of Blood as Packed Cells

Abstract
Accumulation of phthalate plasticizer (di-(2-ethyl-hexyl) phthalate, DEHP) [from polyvinyl containers] was markedly reduced in blood [human] stored as packed cells rather than as whole blood. After the 1st wk, the accumulation rate in whole blood was essentially linear but in packed cells, DEHP accumulation was lower, and reached a plateau. At 3 wk whole blood contained about 3 times more DEHP than did packed cells. Smaller amounts of plasma and restricted diffusion probably limited DEHP accumulation in packed cell preparations.
