As VOCs possess small biological half-lifestyle, profile into the blood will reflect exposures which occurred in the brand new couple of hours quickly before blood range. Yet ,, the atmosphere membership in the NHANES study had been counted that have inactive personal inspections more than periods out-of 2 or 3 days. For this reason, in the event that exposures changed greatly over time bills regarding occasions, air and you will blood account on mix-sectional NHANES database do end up being much more discordant. (2005) listed you to heavens quantities of step one,4-DCB have been most uniform inside their victims of every now and then; this could explain the for example solid relationship anywhere between bloodstream and air amounts of step 1,4-DCB both in Sexton’s studies and the results from the fresh new NHANES investigation (Desk 5).
