Concentration of mercury in vegetation from Hubbard Brook Experimental Forest, NH; Sleepers Brook, VT; Bear Brook, ME; and Huntington Forest, NY

Quantifying mercury (Hg) in tree tissues is essential to understanding the pools and fluxes of Hg in forest ecosystems. We collected and analyzed foliage, bark and bole wood of eight tree species at four sites in the northeastern USA (Huntington Forest, NY; Sleepers River, VT; Hubbard Brook, NH; Bear Brook, ME).
