From: Effect of wine pomace extract on dechlorination of chloroethenes in soil suspension
Dechlorination of tetrachloroethene into ethene in cultured groundwater by wine pomace extract or two fractions of wine pomace extract. Symbols in the graphs represent the concentrations of tetrachloroethene (open squares), trichloroethene (closed squares), 1,2-dichloroethene (open circles), and vinyl chloride (closed circles) over the 40-day test period. Values are means ± SD (n = 3)
