Selected WEBS urine samples showing creatinine corrected results and noncorrected results for selected pyrethroid pesticide metabolites: 3-PBA (3-phenoxybenzoic acid) and trans-DCCA (trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid); TCPy (3,5,6-trichloro-2-pyridinol); selected phthalate metabolites: MEP (mono-ethyl phthalate), MBP (mono-n-butyl phthalate), MBzP (mono-benzyl phthalate), and MEHP (mono-2-ethylhexyl phthalate); and BPA (bisphenol A).
