“…[4][5][6]33,34 Entretanto, o transporte do Pb através da matéria em suspensão de Pb, tanto de origem natural quanto antropogénica, e sua acumulação nos sedimentos se torna preponderante em ambientes estuarinos. 26 Na região metropolitana de Belém, o registro do menor valor de razão 206 Pb/ 207 Pb (1,150 ± 0,001) foi encontrado em aerossóis do distrito de Icoaraci, no setor norte de Belém.…”

“…2 O estudo do Pb adquiriu grande importância em estudos ambientais quando se percebeu que, diferentemente de outros metais pesados, as assinaturas isotópicas do Pb de proveniência antropogênica são distintas da assinatura isotópica de origem natural, podendo, portanto, ser utilizadas como traçador das fontes de contaminação deste metal. [3][4][5][6] A cidade de Belém, Pará, é construída sobre uma península sedimentar estuarina. 7 Nos últimos 20 anos, vem sofrendo um crescimento populacional acelerado, passando de um pouco acima de 1 milhão de habitantes em 1990 para cerca de 2,3 milhões em 2010, com um expressivo crescimento periférico.…”

“…That is the reason why ombrotrophic peat bogs are preferentially used as long-term archives of atmospheric metal deposition, because they are hydrologically isolated from the influence of ground and surface waters, and their inorganic solids are exclusively supplied by atmospheric deposition (Shotyk et al, 1998;Martinez Cortizas et al, 1999). In opposition to bogs and glaciers, lake sediments do not exclusively reflect past atmospheric emissions, but they are more widespread and can thereby provide worthwhile datasets (Eades et al, 2002;Renberg et al, 2002). Moreover, lacustrine sediments generally accumulate continuously and can be precisely dated using radiocarbon techniques as well as natural (e.g., volcanic or flood event) or anthropogenic markers (e.g., artificial radionuclide fallout, fossil fuel combustion residues).…”

a b s t r a c tContinuous high-resolution sedimentary record of heavy metals (chromium (Cr), copper (Cu), lead (Pb), zinc (Zn), manganese (Mn), and mercury (Hg)), from lakes Lucerne and Meidsee (Switzerland), provides pollutant deposition history from two contrasting Alpine environments over the last millennia. The distribution of conservative elements (thorium (Th), scandium (Sc) and titanium (Ti)) shows that in absence of human disturbances, the trace element input is primarily controlled by weathering processes (i.e., runoff and erosion). Nonetheless, the enrichment factor (EF) of Pb and Hg (that are measured by independent methods), and the Pb isotopic composition of sediments from the remote lake Meidsee (which are proportionally more enriched in anthropogenic heavy metals), likely detect early mining activities during the Bronze Age. Meanwhile, the deposition of trace elements remains close to the range of natural variations until the strong impact of Roman activities on atmospheric metal emissions. Both sites display simultaneous increases in anthropogenic trace metal deposition during the Greek and Roman Empires (ca 300 BC to AD 400), the Late Middle Ages (ca AD 1400), and the Early Modern Europe (after ca AD 1600). However, the greatest increases in anthropogenic metal pollution are evidenced after the industrial revolution of ca AD 1850, at low and high altitudes. During the twentieth century, industrial releases multiplied by ca 10 times heavy metal fluxes to hydrological systems located on both sides of the Alps. During the last decades, the recent growing contribution of low radiogenic Pb further highlights the contribution of industrial sources with respect to wood and coal burning emissions.

“…Natural sources of lead include particulates transported to lake sediments directly from erosion of sediments in the catchment, mobilisation of lead from the weathering of catchment bedrock and soils (Renberg et al, 2002), and atmospheric inputs from volcanic eruptions (Graney et al, 1995). Historically, the natural airborne lead fraction has been insignificant compared with supply from catchments (Bindler et al, 2001).…”

“…Historically, the natural airborne lead fraction has been insignificant compared with supply from catchments (Bindler et al, 2001). With increasing anthropogenic additions of lead to the natural environment it has been possible to distinguish anthropogenic sources in disparate environments such as the Arctic (Sturges and Barrie, 1989), Pacific Ocean atmosphere (Settle and Patterson,1982), Antarctic and Greenland ice (Murozumi et al, 1969;Rosman et al, 1993;Hong et al, 1994), peat bogs (Shotyk et al, 1998), Alantic and Pacific Ocean corals (Shen and Boyle, 1987), coastal marine sediments (Chow et al, 1973;Veron et al, 1987) and lake sediments (Edgington and Robbins, 1976;Graney et al, 1995;Monna et al, 1999;Renberg et al, 2002). In these studies, isotopic ratios and/or changes in concentrations of lead have been used to infer a variety of different sources.…”

Global atmospheric sources of lead have increased more than 100-fold over the past century as a result of deforestation, coal combustion, ore smelting and leaded petroleum. Lead compounds generally accumulate in depositional areas across the globe where, due to low solubility and relative freedom from microbial degradation, the history of their inputs is preserved. In lakes there is rapid deposition and often little bioturbation of lead, resulting in an excellent depositional history of changes in both natural and anthropogenic sources. The objective of this study was to use sediments from a regionally bounded set of lakes to provide an indication of the rates of environmental inputs of lead whilst taking into account differences of trophic state and lead exposure between lakes. Intact sediment gravity cores were collected from 13 Rotorua lakes in North Island of New Zealand between March 2006 and January 2007. Cores penetrated sediments to a depth of 16-30 cm and contained volcanic tephra from the 1886 AD Tarawera eruption. The upper depth of the Tarawera tephra enabled prescription of a date for the associated depth in the core (120 years). Each core showed a sub-surface peak in lead concentration above the Tarawera tephra which was contemporaneous with the peak use of lead alkyl as a petroleum additive in New Zealand. An 8 m piston core was taken in the largest of the lakes, Lake Rotorua, in March 2007. The lake is antipodal to the pre-industrial sources of atmospheric lead but still shows increasing lead concentrations from < 2 up to 3.5 µg g -1 between the Whakatane eruption (5530 ± 60 cal. yr BP) and the Tarawera eruption. Peaks in lead concentration in Lake Rotorua are associated with volcanic tephras, but are small compared with those arising from recent anthropogenic-derived lead deposition. Our results show that diagenetic processes associated with iron, manganese and sulfate 2 oxidation-reduction, and sulfide precipitation, act to smooth distributions of lead from anthropogenic sources in the lake sediments. The extent of this smoothing can be related to changes in sulfate availability and reduction in sulfide driven by differences in trophic status amongst the lakes. Greatest lead mobilisation occurs in mesotrophic lakes during seasonal anoxia as iron and manganese are released to the porewater, allowing upward migration of lead towards the sediment-water interface. This lead mobilisation can only occur if sulfides are not present. The sub-surface peak in lead concentrations in lake sediments ascribed to lead alkyl in petroleum persists despite the diagenetic processes acting to disperse lead within the sediments and into the overlying water.
