Ombrotrophic bogs are sensitive ecosystems dependent on atmospheric deposition of precipitation and nutrients for their survival. given their isolation, these sites are vulnerable to airborne pollutants such as mercury and lead. Bogs accumulate material through time, with recent deposition in the upper layers. Bog cores can be used to examine changes in chemistry through time. Anthropogenic pollutants are more concentrated in upper levels of bog cores.
