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).

量化树木组织中的汞（mercury, Hg），对于理解森林生态系统中汞的库与通量至关重要。我们于美国东北部的四个研究站点（纽约州亨廷顿森林、佛蒙特州斯利珀斯河、新罕布什尔州哈伯德布鲁克、缅因州贝尔布鲁克）采集并分析了8个树种的叶片、树皮及主干木材。
