“…This element was indicated as a human carcinogen and a causative factor in renal toxicity, pancreatic cancer, enhanced tumor growth, cardiovascular diseases, and in particular, hypertension [Davis et al, 2006]. It can also inhibit the action of the zinc enzymes by displacing the zinc [Pyrzynska & Kilian, 2007].…”

A cloud-point extraction (CPE) process using the nonionic surfactant, Triton X-114 to extract Cd(II) ions from aqueous solutions was investigated. The method is based on the ion-pairing reaction of Cd(II) with Victoria blue B (VBB + ) in presence of excess iodide at pH 4.0 and extraction of the complex formed. The chemical variables affecting CPE efficiency were studied, and the analytical characteristics of the method were obtained. The calibration curves were obtained in the ranges of 1.0-30 and 10-500 µg/L for Cd(II) ion with the detection limits of 0.34 and 3.8 µg/L at 608 and 634 nm, respectively. The selectivity study was also tested. The precision (N: 5, 25 µg/L) was 2.85% relative standard deviation. The results obtained for two certified reference samples were in a good agreement with the certified values. The method was successfully applied to the determination of Cd(II) in beverage samples.Brought to you by | MIT Libraries Authenticated Download Date | 5/10/18 11:53 PM

“…To determine the quantity of cadmium in biological samples can be problematic, especially due to the low concentrations of the metal and the large variety of matrixes among the samples (Davis et al, 2006), therefore, differences in metal concentrations between studies are common and expected, being important to take into consideration the techniques applied to the study. Even so, a comparison with literature becomes indispensable due to the limited bibliography that generally involves a low number of analysed individuals (Siciliano et al, 2005;Seixas et al, 2009).…”

Cadmium concentrations were assessed in the hepatic tissues of 27 Guiana dolphins, Sotalia guianensis, that were found stranded in the estuary of Cananéia-Iguape, southeast of Brazil, between 2009 and 2012. The samples' digestion was performed through acid digestion with HNO 3 and the quantification was held by flame atomic absorption spectrometry (FAAS). For 11 of the sampled animals, concentrations did not exceed the limit of quantification of 0.1µg.g -1 stipulated by the method. The concentrations varied from above detection limit to 1.79µg.g -1 (wet weight), for a average of 0.39µg.g -1 which is in accord with the literature, as low values of the metal were commonly found in the tissues of the specie on the Brazilian coast. No differences were observed in the accumulation of cadmium between sexes, age classes or the curvilinear length. The accumulation found in the livers may reflect the Guiana dolphins diet in the region and the bioavailability of the metal in the system. This study provides new data about the accumulation of cadmium in animals of the Brazilian coast, contributing towards the status of conservation of the specie.

“…3] . The most human cadmium exposure comes from the tobacco smoke and from ingestion of foodwhich most of that arises from the uptake of cadmium by plants from fertilizers, sewage sludge, manure and atmospheric deposition [1,4] . More recently, the possible role of cadmium in human carcinogenesis has been also studied [4,5] .…”
