“…The mean Pb addition rate is over a six-fold increase in Pb deposition compared to modern trace metal dry deposition rates in the NJ region (1.83 ug cm -2 y -1 ) (Yi et al, 2006). Similar soil-Pb addition rates were calculated for an upland soil 322 km to the westsouthwest (Pb addition rate of 6 -10 ug cm -2 y -1 ) (Ma et al, 2014). A much slower bulk atmospheric Pb deposition rate (0.261±0.77 ug cm -2 y -1 ) was documented 560 km north, in Lac Hertel, southern Quebec (Gélinas et al, 2000) (Fig.…”

“…Finally, numerous ruins of furnaces are located within 30 km of the field site. Soils at the SSHCZO retain metals derived from the atmospheric deposition of particulates released to the atmosphere during iron smelting at these sites, as well as other byproducts of other industries [ Herndon et al ., ; Ma et al ., ].…”

“…Over the geologically brief time scale of industrialization (decades to millennia), humans have redistributed elements across the Earth's surface, leading to enrichment of many elements in soils, water, air, and biota [ Nriagu and Pacyna , ; Rauch and Pacyna , ; Sen and Peucker‐Ehrenbrink , ]. Environmental regulation has curbed industrial emissions in many countries; however, soils and sediments act as a sink for deposition and provide a long‐term record of atmospheric inputs [ Cole et al ., ; Ma et al ., ]. Soils subsequently act as a source of atmospheric contaminants to river systems, even decades following deposition [ Rice et al ., ].…”

Many surface soils are enriched in metals due to anthropogenic atmospheric inputs. To predict the persistence of these contaminants in soils, factors that impact rates of metal removal from soils into streams must be understood. Experiments at containerized seedling (mesocosm), pedon, and catchment scales were used to investigate the influence of vegetation on manganese (Mn) transport at the Susquehanna/Shale Hills Critical Zone Observatory (SSHCZO) in Pennsylvania, USA, where past atmospheric inputs from industrial sources have enriched Mn in surface soils. Large quantities of Mn that were leached from soil components into solution were taken up by vegetation; as a result, only relatively small quantities of Mn were removed from soil into effluent and streams. Manganese uptake into vegetation exceeded Mn losses in soil leachate by 20-200X at all scales, and net Mn loss from soils decreased in the presence of vegetation due to uptake into plant tissues. The majority of Mn taken up by forest vegetation at SSHCZO each year was returned to the soil in leaf litter and consequently immobilized as Mn oxides that formed during litter decomposition. Thus, plant uptake of Mn combined with rapid oxidation of Mn during litter decomposition contribute to long-term retention. Current release rates of soluble Mn from SSHCZO soils were similar to release rates from the larger Susquehanna River Basin, indicating that the processes observed at SSHCZO may be widespread across the region. Indeed, although atmospheric deposition of Mn has declined, surface soils at SSHCZO and throughout the eastern United States remain enriched in Mn. If recycling through vegetation can attenuate the removal of Mn from soils, as observed in this study, then Mn concentrations in soils and river waters will likely decrease slowly over time following watershed contamination. Understanding the role of vegetation in regulating metal transport is important for evaluating the long-term effects of historical and ongoing metal loading to soils.

“…13). In comparison, biocycling has little influence on Pb and Mo, which instead are retained in soils through complexation with soil organic matter (Ma et al, 2014; Kraepiel et al, 2015). These findings reinforce the importance of plant–soil interactions in controlling the export of certain contaminants either directly due to intense biocycling (e.g., Mn) or indirectly due to contributions of soil organic matter (e.g., Pb and Mo).…”

Core Ideas Studying the critical zone requires targeted research on water, energy, gas, solutes, and sediments. The SSHCZO targets a 165‐km2 watershed on sedimentary rocks in the northeastern United States. One SSHCZO subcatchment, Shale Hills, provides extraordinary data describing a shale CZ. The Susquehanna Shale Hills Critical Zone Observatory (SSHCZO) was established to investigate the form, function, and dynamics of the critical zone developed on sedimentary rocks in the Appalachian Mountains in central Pennsylvania. When first established, the SSHCZO encompassed only the Shale Hills catchment, a 0.08‐km2 subcatchment within Shaver's Creek watershed. The SSHCZO has now grown to include 120 km2 of the Shaver's Creek watershed. With that growth, the science team designed a strategy to measure a parsimonious set of data to characterize the critical zone in such a large watershed. This parsimonious design includes three targeted subcatchments (including the original Shale Hills), observations along the main stem of Shaver's Creek, and broad topographic and geophysical observations. Here we describe the goals, the implementation of measurements, and the major findings of the SSHCZO by emphasizing measurements of the main stem of Shaver's Creek as well as the original Shale Hills subcatchment.
