The Tobari Coastal Lagoon, located in the Gulf of California, receives water discharges from agricultural areas, shrimp farms, livestock facilities, and urban wastewater. During four seasons, the concentration of 10 PTE (As, Cd, Pb, Ni, Cu, Fe, Mn, Zn, Cr and Hg) was assessed in water before (FW, irrigation water) and after discharged through agric...
Article
The Sierra Huautla (Morelos State, Mexico) is a biological reserve with historical mines of Ag and Pb. In this area, waters used by inhabitants are contaminated by arsenic (As). An integrated environmental survey was realized both in waters and sediments to better constrain the source and the mobility of As and other trace elements. Two areas of in...
Article
The Neoproterozoic sequence of volcanic rocks in the Camaquã Basin included in the Lavras do Sul Shoshonitic Association hosts disseminated Cu deposits. The volcanic sequence in the Seival Mine area includes andesitic lava flows, lapilli tuff, volcanic agglomerate and andesitic dikes with pervasive alteration. The hydrothermal alteration is interpr...
Article
The orogenic Au (As, Bi, Ag) mineralization (up to 31 g/t) of the Buracão area is hosted in the metasedimentary Paleo–Mesoproterozoic Traíras Formation, Araí Group, Brasília Fold Belt, Brazil. In order to discuss the P–T–X conditions that generated this mineralization, we present mineralogical, geochemical and fluid inclusion data of veins, gold an...
Article
The Seival Mine, located in the Camaquã Basin, hosts several small Cu and Ag ore deposits in volcano–sedimentary sequence surrounding the Lavras do Sul Intrusive Complex. Alteration minerals consist of calcite, sulfate, smectite and chlorite/smectite associated with Cu–rich sulfides. The mass balance calculations from less altered to altered volcan...
Article
The Seival Mines are situated in the NE portion of the Lavras do Sul mining district, southernmost Brazil. They are hosted by volcanic and sub-volcanic rocks of Neoproterozoic age, which are part of the post–collisonal Camaquã Basin volcano–sedimentary sequence. The mineralization occurs in shoshonitic volcanic and sub–volcanic rocks of the Lavras...

This study focusses on arsenic (As) because this metalloid presents a great health issue in a region of Morelos state in Mexico (Huautla district), due to past mining activities. The main aim of this study is to better constrain As behavior and transport in this hydrosystem. During two contrasting hydrological periods, total and dissolved concentra...
Article
A detailed study on arsenic (As) in rocks and water from the Var River watershed was undertaken aiming at identifying (i) the origin and the distribution of As in this typical Alpine/Mediterranean basin, and (ii) As input into the Mediterranean Sea. Dissolved As concentrations in the Var River range from 0.1 to 4.5 μg ⋅ L− 1, due to high hydrologic...
Article
Barium:calcium and molybdenum:calcium ratios were investigated in shells of the tropical scallop Comptopallium radula . Three juvenile specimens were harvested alive in the southwest lagoon of New Caledonia after a 1-year hydrological survey. Calcite samples representing a few hours of biomineralization were laser-ablated along the maximal growth a...
Article

Skeletal molybdenum/calcium ([Mo]/[Ca])shell ratios were examined in shells of the Great Scallop Pecten maximus collected in temperate coastal environments of Western Europe (42 to 49° N). These ratios were determined by quantitative LA-ICP-MS analyses of daily striae taken every third day (i.e. a temporal resolution of 3 days) in 36 flat valves (2...

Skeletal molybdenum/calcium ([Mo]/[Ca])shell ratios were recently examined in bivalves. These ratios were determined by quantitative LA-ICP-MS analyses every third daily striae (i.e. a temporal resolution of 3 days) in 36 flat valves of the Great Scallop shells Pecten maximus (2-year old; 3 shells/year) collected in temperate coastal environments o...
Article
Skeletal barium/calcium ([Ba]/[Ca]) shell ratios were measured every third daily striae in 39 flat valves of the Great Scallop Pecten maximus collected in temperate coastal environments of Western Europe. A methodical evaluation of the ([Ba]/[Ca]) shell ratio was performed for the first time and demonstrates that ([Ba]/[Ca]) shell profiles are repr...
Article
Barium : calcium and molybdenum : calcium ratios were investigated in shells of the tropical scallop Comptopallium radula. Three juvenile specimens were harvested alive in the southwest lagoon of New Caledonia after a 1-yr hydrological survey. Calcite samples representing a few hours of biomineralization were laser-ablated along the maximal growth...
Article
Skeletal barium/calcium ([Ba]/[Ca])<sub>shell</sub> ratios were measured every third daily striae in 39 flat valves of the Great Scallop Pecten maximus (2-year old; 3 shells/year) collected in temperate coastal environments of Western Europe. Variations of ([Ba]/[Ca])<sub>shell</sub> ratio were first demonstrated reproducible for several scallop in...
Article
During their growth, bivalves are recognized to archive minor and trace elements within their shells which may reflect environmental conditions at the sediment-water interface (SWI). Shells from juvenile Great Scallops (Pecten maximus (L.)), which develop a daily calcite growth layer, were collected in the Bay of Seine (France) and examined by matr...
Article
A micro-scale method has been developed for analysis of trace-element concentration profiles in the calcium carbonate shell of the Great Scallop (Pecten maximus). UV laser ablation at 266-nm coupled with ICP-MS detection was used to analyse daily calcite striae of shell samples to obtain high temporal resolution of trace element incorporation. Anal...
Article
The development of Laser Ablation - Inductively Coupled Plasma - Mass spectrometry coupling (LA-ICP-MS) conduced to the quantitative micro analysis of trace elements (TE) in calcium carbonate (CaCO3) matrices by the use of CaCO3 standards (TE range of concentrations: 0-500 µg.g-1). Quantitative analyses of TE along the daily calcite striae of the G...
Article
Speciation analysis of four selenium species (selenite, selenate, selenocystine, and selenomethionine) has been performed by on-line coupling of liquid chromatography (LC), UV decomposition, hydride generation (HG), and atomic-fluorescence spectrometry (AFS). Because only selenite (Se(IV)) can generate hydrides, on-line conversion of organic and in...
Article
Levels of nickel and vanadium, trace metals found in high concentration in the oil spilled from the "Erika" tanker off Brittany (France) in December 1999 (41 +/- 1 and 87 +/- 3 mg kg(-1) respectively), have been monitored over a one-year period following this accidental event in several benthic invertebrates. Ni and V in mussels (Mytilus edulis) an...
