Multi-isotopic fingerprints (Pb, Zn, Cu) applied for urban aerosol source apportionment and discrimination.
Zinc and lead isotopic compositions of PM from Sao Paulo showed diurnal variations indicating the industrial contributions carried by cold fronts and road dust suspension associated to high wind speeds and traffic pattern. Expand
Tracing of anthropogenic zinc sources in coastal environments using stable isotope composition
Abstract The use of zinc isotopes to trace anthropogenic sources in coastal areas has been tested in this study. We determined the stable isotopic composition of zinc in sediment cores, suspendedExpand
Ion Exchange Chromatography and Mass Bias Correction for Accurate and Precise Zn Isotope Ratio Measurements in Environmental Reference Materials by MC-ICP-MS
Precise and accurate d66/64Zn data for environmental reference materials (RMs) including rocks, sediments, soils and plants are presented in order to improve the metrological traceability andExpand
Assessing man-induced environmental changes in the Sepetiba Bay (Southeastern Brazil) with geochemical and satellite data
Abstract The Sepetiba Bay, Southeastern Brazil, has undergone intense environmental changes due to anthropogenic influence. This work aims to: (i) evaluate the changes in the drainage landscape useExpand
Zinc isotopes as tracers of anthropogenic sources and biogeochemical processes in contaminated mangroves
Abstract Recent work has shown that variations in zinc (Zn) isotope ratios enable us to identify contamination sources in the terrestrial environment and uptake processes in higher plants. Here inExpand
A critical examination of the possible application of zinc stable isotope ratios in bivalve mollusks and suspended particulate matter to trace zinc pollution in a tropical estuary.
The zinc isotope systematics of the SPM was in line with mixing of zinc derived from fluvial material and from metallurgical activities, which suggests that additional factors such as speciation, bioavailability and bioaccumulation pathways (via solution or particulate matter) influence the zinc isotopes of bivalves.

Assessment of the metal contamination evolution in the Loire estuary using Cu and Zn stable isotopes and geochemical data in sediments.
This work demonstrates the applicability of Zn isotopes to identify anthropogenic Zn sources in coastal systems, even under a low to moderate degree of contamination, as well as the need to constrain Cu sources. Expand
Geological and anthropogenic influences on sediment metal composition in the upper Paracatu River Basin, Brazil
This work reports a geochemical study of sediments from the upper Paracatu River Basin. The objective is to define the influences of Au, Zn, and Pb mineral deposits and mining activities on theExpand
Copper, zinc and lead isotope signatures of sediments from a mediterranean coastal bay impacted by naval activities and urban sources
Abstract Toulon bay is severely impacted by metal contamination induced by past and recent naval activities. In this work, Cu, Zn and Pb isotope compositions and elemental concentrations ofExpand
Biogeochemical mechanisms controlling trophic state and micropollutant concentrations in a tropical artificial lake
Lake Paranoá is a human-made water reservoir created in 1959 together with the new capital of Brazil (Brasilia). With the demands of urban development, population growth, and land use changes, theExpand
