Saint-Pierre and Miquelon (SPM) is a small archipelago where instrumental measures based on water column velocity and temperature profiles compiled comprehensive evidence for strong near-diurnal (25.8h) current and bottom temperature oscillations (up to 11.5 °C) which is possibly the largest ever observed — at any frequency — on a stratified mid-latitude continental shelf. The main objective of our study was to identify if Placopecten magellanicus can record on its shell these high frequency environmental variations. To this end, we have tried to identify proxies for water temperature and food availability through development of a new ultra-high resolution LA-ICPMS analyses method capable of resolving shell surface elemental composition with a 10 μm...

Abstract High copper (Cu) levels in uprooted old vineyard soils may cause toxicity in transplanted young vines, although such toxicity may be reduced by inoculating plants with arbuscular mycorrhizal fungi (AMF). The objective of this study was to evaluate the effects of AMF on the plant growth, chlorophyll contents, mycorrhizal colonization, and Cu and phosphorus (P) absorption in young vines cultivated in a vineyard soil contaminated by Cu. Commercial vineyard soil with high Cu levels was placed in plastic tubes and transplanted with young vines, which were inoculated with six AMF species (Dentiscutata heterogama, Gigaspora gigantea, Acaulospora morrowiae, A. colombiana, Rhizophagus clarus, R. irregularis) and a control treatment on randomized blocks...

Effects of nitrogen fertilizer input on the composition of mineral elements in corn grain

Abbas, M.M.; Shakweer, L..

The effect of temperature, pH and trace elements concentration in the ambient water on the uptake and accumulation of Cu, Zn, Ni and Pb in various organs of fish and parts of aquatic plants of Edku Lake were studied. It was found that higher water temperature and lower pH during summer increased the rates of trace metals uptake by the most common fish species Oreochromis niloticus. The concentrations of Cu, Zn, and Ni in the various organs of fish were affected by the concentrations of these elements in the water. Cu, Zn, Ni and Pb attained higher concentrations in the roots of Eichormia crassipes if compared with their concentrations in the other parts of this aquatic plant. Sex of fish can be considered as an important factor affecting the accumulation...

Excessive and inappropriate application of industrial N fertilizer can result in severe environmental and ecological problems, but whether the input of N fertilizer could affect the composition of mineral elements in corn has not been reported. Effects of input of N fertilizer on the composition of mineral elements (Se, Mo, I, Mn, Fe, Cu, Zn, Ca, Cr, K, Na, and Mg), in corn grain were investigated by ICP-MS (inductive coupling plasma-mass spectrometry). Se, I, Mn, Fe, Zn, Cr, K and Ca were significantly lower in the treatments with N fertilizer compared to a control without N fertilizer. There was a significant negative conrrelation (R) between four mineral elements and N fertilizer input: I, -0.71; Zn, -0.65; Ca, -0.75; K, -0.89. Therefore appropriate...

ABSTRACT We assessed elemental composition of the liver in mice subjected to one-time or chronic consumption of the juice of vegetables cultivated in a vegetable garden built over deposits of coal waste. Lactuca sativa L. (lettuce), Beta vulgaris L. (beet), Brassica oleracea L. var. italica (broccoli) and Brassica oleracea L. var. acephala (kale) were collected from the coal-mining area and from a certified organic farm (control). Elemental composition was analyzed by particle-induced X-ray emission (PIXE) method. Concentrations of Mg, S, and Ca of mice subjected to one-time consumption of broccoli and concentrations of these same elements plus Si of mice receiving kale were higher in the coal-mining area. Concentrations of P, K, and Cu were increase after...

Evaluation de la contamination chimique par les metaux traces (cd, pb, hg et zn) du zooplancton et de la sardinelle (Sardinella aurita) dans le golfe de tunis

Ennouri, R.; Chouba, L.; Kraeim, M.M..

La présente étude a pour but de déterminer l’organotropisme de quatre métaux traces (Cd, Pb, Hg et Zn) ainsi que leurs concentrations dans le zooplancton et dans trois organes (muscle, foie et branchies) de la sardinelle (Sardinella aurita) provenant du golfe de Tunis. Les résultats ont montré que les concentrations moyennes des quatre métaux dosés (Cd, Pb, Hg et Zn) sont plus élevées dans la sardinelle que dans le zooplancton. Ceci est dû à la bioamplification de ces éléments dans la sardinelle qui occupe un niveau trophique élevé de la chaîne alimentaire marine. Pour le Pb, le Hg et le Zn, les teneurs le plus élevées ont été enregistrées dans les branchies de la sardinelle, alors que le Cd est concentré davantage au niveau du foie. Les concentrations...

Nickel, although essential to plants, may be toxic to plants and animals. It is mainly assimilated by food ingestion. However, information about the average levels of elements (including Ni) in edible vegetables from different regions is still scarce in Brazil. The objectives of this study were to: (a) evaluate and optimize a method for preparation of vegetable tissue samples for Ni determination; (b) optimize the analytical procedures for determination by Flame Atomic Absorption Spectrometry (FAAS) and by Electrothermal Atomic Absorption (ETAAS) in vegetable samples and (c) determine the Ni concentration in vegetables consumed in the cities of Lorena and Taubaté in the Vale do Paraíba, State of São Paulo, Brazil. By means of the analytical technique for...

Extensive larval dispersal and restricted movement of juveniles on the nursery grounds of sole in the Southern North Sea

Delerue-ricard, Sophie; Darnaude, Audrey M.; Raeymaekers, Joost A.m.; Dundas, Siv Hjorth; Skadal, Julie; Volckaert, Filip A.m.; Geffen, Audrey J..

Connectivity between spawning and nursery grounds influences the colonization, replenishment and resilience of populations of marine organisms. Connectivity rate, measured as the exchange of individuals between spawning and nursery grounds, is therefore a crucial determinant of stock size. However, connectivity of early-life stages is hard to explore due to sampling limitations and insufficient knowledge on potential larval sources. Here we present new insights into pre- and post-settlement dispersal of the common sole (Solea solea L.) at a spatial scale of 5–500 km in the Southern North Sea. Patterns at a scale of <100 km were considered local, whereas patterns further than 100 km were considered regional. Multi-elemental signatures of the otolith edge...

Successive applications of pig slurry and pig deep litter may lead to an accumulation of copper (Cu) and zinc (Zn) fractions in the soil profile. The objective of this study was to evaluate the Cu and Zn forms and accumulation in a Sandy Typic Hapludalf soil after long-term application of pig slurry and deep litter. In March 2010, eight years after initiating an experiment in Braço do Norte, Santa Catarina (SC), Brazil, on a Sandy Typic Hapludalf soil, soil samples were collected from the 0-2.5, 2.5-5.0, 5-10 and 10-15 cm layers in treatments consisting of no manure application (control) and with applications of pig slurry and deep litter at two levels: the single and double rate of N requirement for maize and black oat succession. The soil was dried,...

Mohamed, A.W..

The grain size distribution and arameters, major and trace elements, carbonate, total phosphorus, organic carbon and total organic matter has been assessed for core sediments collected in the intertidal area of Qusier, Safaga and Hurghada harbors in July 2002. Mud is the dominant fraction in almost all samples of Qusier core and some samples of Safaga and Hurghada cores. The reason for the high mud content of all Qusier core samples and some samples of Safaga and Hurghada cores is due to the terrigenous flux of wadies, phosphate deposits, landfill and dredging in these areas. Metals concentrations in the core sediments vary between sites within a wide range for Cu, Zn, Pb, V, Ni and Cd. Concentration of metals in the sediments at the top of cores is the...

GEOCHEMICAL BACKGROUND IN AN OXISOL

REA

Cembranel,Adir S.; Sampaio,Silvio C.; Remor,Marcelo B.; Gotardo,Jackeline T.; Rosa,Pábolla M. Dalla.

ABSTRACT Geochemical background establishment is indispensable to determine the actual state of contamination of soils and sediments. However, no scientific consensus exists regarding the methodology for determining these values. In this context, this study aimed to establish the geochemical background in an Oxisol (Rhodic Hapludox) by means of an integrated method that uses direct and indirect soil analyses to identify the most appropriate calculation methodology. Soil samples were collected in a permanent preservation area of the Cascavel River watershed, PR, Brazil. The elements Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn present in soil samples were quantified by flame atomic absorption spectrometry. The use of a permanent preservation area is...

ABSTRACT This paper presents geochemical behaviour of trace elements of the felsic alkaline rocks of the state of Rio de Janeiro, Brazil, with special attention of fractional crystallization and continental crust assimilation. Fractionation of leucite and K-feldspar increases Rb/K and decreases K2O/(K2O+Na2O). Primitive nepheline syenite magmas have low Zr/TiO2, Sr, and Ba. On the Nb/Y vs. Zr/TiO2 diagram, these rocks are projected on the field of alkaline basalt, basanite, and nephelinite, instead of phonolite. Well-fractionated peralkaline nepheline syenite has high Zr/TiO2 but there are no zircon. The diagrams of silica saturation index (SSI) distinguish the trends originated form fractional crystallization and crustal assimilation. In the field of...

Growth and metal uptake of microalgae produced using salt groundwaters from the Bay of Bourgneuf

Pierce, G; Stowasser, G; Hastie, L; Bustamante, Paco.

Cadmium (Cd) and mercury (Hg) levels were measured in the tissue samples of two loliginid (Alloteuthis sp. and Loligo forbesi) and two ommastrephid (Todarodes sagittatus and Todaropsis eblanae) squid species collected from research cruise and fishery (market) samples in UK waters during 2004-05. Concentrations of Cd were generally higher in the ommastrephids, in all tissues except muscle. Hg concentrations were higher in T sagittatus than in the loliginids. In L. forbesi, metal concentrations differed between tissues and also varied in relation to body size, geographic origin, and season. Cd levels decreased with increasing body size. This may be related to a shift in the diet with growth, since small L. forbesi feed on benthic invertebrates that have...

The Bay of Bourgneuf, France, is a main site of shellfish production. In the marshes along the bay, oyster intensive rearing and fattening need the mass production of microalgae. Salt groundwaters, available in this region, support a large part of this production for aquaculture. Studies carried out by local authorities have brought to the fore the accumulation of lead (Pb) in several samples of algal pastes derived from cultures using salt groundwater. The aim of this study was to compare growth, nutritional value and metal (Cd, Cu, Pb and Zn) uptake of four microalgae grown in two salt groundwaters or in enriched coastal seawater. Cultures of microalgae used in aquaculture (Haslea ostrearia, Phaeodactylum tricornutum, Skeletonema costatum and Tetraselmis...

Few investigations have been carried out about the comparison of desorption rate and amount of heavy metals extracted successively by organic acid mixtures mimicking the rhizosphere and routine extractants in sewage sludge-amended soils. Extractions of Zn, Cd, Ni, Cr, and Cu were performed in samples of a sewage sludge-amended soil using seven extractants: four organic acid mixtures and three routine extractants (DTPA, Mehlich-I, and ammonium acetate). Results from single pass extractions, in which the extractable metal contents were determined by simply extracting the soil a single time, as well as from 15 successive extractions, in which the solid residues of the first extraction was successively extracted 14 additional times, of heavy metals were...

The monitoring of heavy metal concentrations in areas under intensive agriculture is essential for the agricultural sustainability and food safety. This paper evaluates the total contents of heavy metals in soils and mango trees in orchards of different ages (6, 7, 8, 9, 10, 11, 14, 16, 17, 19, and 26 years) in Petrolina, Pernambuco, Brazil. Soil samples were taken from the layers 0-20 cm and 20-40 cm, and mango leaves were collected in the growth stage. Areas of native vegetation (Caatinga) adjacent to the cultivated areas were used for comparison. The total concentrations of heavy metals (Cu, Cr, Fe, Zn, Mn, Ni, and Pb) were determined in soils and leaves. In general, mango cultivation led to Cu and Zn accumulation in the soil surface and to a reduction...

We investigated the levels of F and its relationship with As, B and V in ground and surface waters of the southern Pampas, where cases of dental and skeletal fluorosis, and arsenic in hair and urine samples have been detected in the rural population. Eating vegetables and cereals grown in irrigated areas with excessive fluoride may increase the risk of fluorosis due to the addition of the extra F contributed from other sources such as drinking water. Moreover, if these elements exceed the tolerance of crops produce toxicity and, like salinity, they decrease the potential crop yield. Within an area of 2300 km², 81 samples were taken from surface and groundwaters to determine F, As, B and V. Fluoride was detected in 86% of the sampled groundwaters, and in...
