Abstract

We conducted community-based participatory research with a cross-sectional repeated measures design in Visalia, Tulare County, California. We report on a novel modification of both an existing field dust wipe method and laboratory analysis procedure for extracting then quantifying phthalates from pre-wetted wipes. Twelve individuals- of 34 at baseline from convenience sample meeting selection criteria recruited in spring 2009- agreed to comprehensive home visits; nine completed first visits July, 2009 (Shendell et al, 2010). We confirmed each participant at baseline had 13 physician-diagnosed respiratory diseases, e.g., asthma. Four of five targeted phthalates [DEHP (diethylhexyl phthalate), DBP (dibutyl phthalate), DEP (diethyl phthalate) and BBzP (butylbenzyl phthalate), not DINP (diisononyl phthalate)] were measured above study analytic detection limits in most study homes. Measured levels of phthalates varied between kitchen floors compared to front hallways/entry areas (FH) and TV rooms/dens for DBP and DEHP; for DnBP and BBzP, levels were consistently higher in FH.
