Mercury (Hg) is a persistent environmental contaminant and can accumulate and concentrate in food webs as methylmercury (MeHg), presenting a health risk to humans and wildlife. Multiyear monitoring and modeling studies have shown that atmospheric Hg in litterfall is an important form of Hg deposition to forests. Litterfall consists primarily of leaves with some amounts of twigs, bark, flowers, seeds, fruits, and nuts. Atmospheric Hg accumulates in the forest canopy material and transfers to the forest floor in litterfall. This data set is derived from monthly litterfall collected at the National Atmospheric Deposition Program (NADP) Mercury Deposition Network (MDN) site at El Verde, Puerto Rico, identification number...
