Gross classification of CB contaminations, based on gas chromatography data (25). −, not a constituent; +, minor constituent; ++, medium constituent; +++, major constituent of the Wittenberg site.
Experimental (28).
Calculated (39).
NPO, no product observed.
mAbsmax, milli-absorbance units at absorption maximum.
