Forty-four elements were determined in crown vetch sampled along a heavily travelled highway in Virginia. Twenty-four elements including Ba, Br, Cr, Pb, Sn, and Sr were higher in this vegetation than in control vetch. When the highway-grown vetch was fed as 45% (dry weight) of the diet to guinea pigs for 100 days, Ba, Br, Cr, Pb, Sn and Sr were found at higher concentrations in the various animal tissues than in those of guinea pigs similarly fed the control crown vetch.
