Table summary
This table displays the results of volatile organic compounds with significant difference (p<0.05) between field blanks and cleaning blanks. The information is grouped by volatile organic compound (appearing as row headers), fdl (µg/m3), cleaning blank (n=74) and field blank (n=173), calculated using geometric mean (µg/m3) and median (µg/m3) units of measure (appearing as column headers).
