SÃO VICENTE ESTUARINE SYSTEM.Three approaches were applied to evaluate metal contamination in 41 sediment samples from the Santos -São Vicente Estuarine System: normalization Al, statistical analysis and quality guidelines (SQGs).The results showed increases concentrations of Zn, Ni, Pb, Cd, Cr Hg, which seemed be associated with human activities.The levels Fe Co probably crustal material or natural weathering processes.About 45% presented exceeding TEL-ERL, occasionally adverse biological...
Single-particle inductively coupled plasma-mass spectrometry (sp-ICP-MS) is a powerful technique that enables the simultaneous measurement of nanoparticle size and quantification metal-containing nanoparticles at real concentrations. These measurements are critical for understanding potential uses in various fields. However, sp-ICP-MS not yet considered mature methodology. Standardization necessary, particularly assessing reliability distribution measurements. This study aims to standardize...
The distribution of mercury contamination in the Santos - São Vicente Estuarine System was observed through analysis 31 sediments samples collected from that system, including mangrove areas under urban, industrial and harbor influence zones. range values obtained between 0.04 1.19 µg g -1. About 90% presented Hg > 0.13 g-1 levels, which is limit established by Canadian legislation adopted environmental control agency Paulo State Brazil (CETESB), below no adverse effect on biological...
This study aimed to evaluate the metal concentration of sediments from Santos Estuarine System (Sao Paulo State, Brazil). during winter 2010. Surface sediment samples were collected 16 sites distributed along with estuarine system. Aliquots homogenized sub-sampled for chemical and granulometric analyses. The results compared reference values Canadian Sediment Quality Guidelines. Principal components analysis (PCA) cluster used identify clarify relationships among parameters. PCA grouped...

Finding solutions to mitigate the impact of pollution on living systems is a matter great interest. Homeopathic preparations toxic substances have been described in literature as attenuation factors for intoxication. Herein, an experimental study using Artemia salina and mercury chloride was developed model identify aspects related bioresilience.The aim describe effects homeopathic Mercurius corrosivus (MC) cysts hatching bioavailability.Artemia were exposed 5.0 µg/mL during phase. MC...
RIBEIRA DE IGUAPE RIVER.This study investigated the contamination of Ribeira de Iguape River -RIR by Cd, Zn, Cr and Pb, using bivalve Anodontites tenebricosus as a biomonitor.Metal concentrations in tissue samples were measured HR-ICPMS.Bivalve tissues exhibited mean levels 1.00 µg/g Cd; 152.89 Zn; 14.79 4.40 Pb.Lead comparable to those reported for moderately contaminated sites.The results showed that Pb is bioavailable bivalves, exhibiting high exceeding both natural reference values human...
Four approaches were applied to evaluate the metal contamination in 47 sediment samples (< 63 µm fraction) collected at 13 fishing points of Billings Reservoir: quality guidelines (SQGs), geoaccumulation index (I Geo), pollution (MPI) and statistical analyses. Only Fe Co concentrations seemed be associated with crustal material or natural weathering processes, while Al, Cd, Cr, Cu, Hg, Mn, Ni, Pb Zn showed increases their concentrations, which anthropogenic sources. MPI identified most...
Abstract The presence of legacy contaminants in sediments from three Marine Protected Areas (MPAs) the coast São Paulo State was evaluated. Four sampling surveys were conducted between 2013 and 2015 10 sites, distributed along Laje de Santos Xixova-Japui Parks (PEMLS XJSP, respectively) Central Coast Protection Area (APAMLC). Samples analyzed for sediment texture, total organic carbon, CaCO3, metals (Al, Fe, Hg, Cd, Co, Cr, Cu, Ni, Pb Zn), aliphatic polycyclic aromatic hydrocarbons (AH PAH)....
Analysis of major metallic elements in Chilean wines by atomic absorption spectroscopy.Cien.Inv.Agr.37(2): 77-85.A set 75 wine samples from seven the producing regions Chile were analyzed with flame spectroscopy (AAS) to determine their content (K, Mg, Ca, Na, Fe and Zn).The results obtained further principal component analysis (PCA) an attempt loosely discriminate these according grape type geographical origin.The metal concentrations measured within normal ranges, previously published data...
Pb, Cd, Zn, and Cu concentrations their distribution in liver, gill, muscle tissues of the catfish Cathorops spixii Genidens genidens were investigated order to provide information concerning bioaccumulation processes these species. Fish collected one estuary subject slight human influence (Cananéia) two regions within Santos-São Vicente estuary, São Paulo, Brazil, distinct anthropogenic influences: 1) industrial 2) domestic. In general, highest Cu, Pb found liver tissue. Muscle showed...
Abstract In this study, the quality of sediments from three Marine Protected Areas (MPAs) located on coast São Paulo (Laje de Santos State Park - PEMLS; Xixova-Japui XJSP; and Central Coast Protection Area APAMLC) was assessed. Four sampling surveys were conducted (September/October 2013; January 2014; July 2015). Sediment samples collected at10 sites, distributed along 3 MPAs. Samples analyzed for sediment texture, total organic carbon, CaCO3, metals, aliphatic polycyclic aromatic...
