“…The data obtained from present coprecipitation method have been compared with those of recently reported heavy metal separation and preconcentration methods (Tab. 6) [3,11,[26][27][28][29][30][31][32]. The proposed method is primarily superior to those reported methods in literature in terms of no need to consumption of organic solvent.…”

A new separation and preconcentration technique based on coprecipitation of Cu (II) and Ni(II) ions by the aid of Mo(VI)/di-tert-butyl{methylenebis[5-(chlorobenzyl)-4H-1,2,4-triazol-3,4-diyl]}biscarbamate (BUMECTAC) precipitate has been established. The Mo(VI)/ BUMECTAC precipitate was dissolved by concentrated HNO 3 and the solution was completed to 5.0 mL with distilled/deionized water. The levels of the analyte ions were determined by flame atomic absorption spectrometer. The effects of experimental conditions like HNO 3 concentration, amount of BUMECTAC and Mo(VI), sample volume, etc. and also the influences of some foreign ions were investigated in detail on the quantitative recoveries of analyte ions. The preconcentration factors were found to be 40 for Cu(II) and 100 for Ni(II) ions. The detection limits for Cu(II) and Ni(II) ions based on 3s (N:10) were 0.43 and 0.70 mg L À1 , respectively. The relative standard deviations were found to be lower than 4.0% for both analyte ions. The accuracy of the method was checked by spiked/recovery tests and the analysis of two certified reference materials (Environment Canada TM-25.3 and CRM-SA-C Sandy Soil C). The procedure was successfully applied to sea water and stream water as liquid samples and baby food as solid sample in order to determine the levels of Cu(II) and Ni(II) ions.

The toxicity of nanoparticles has been linked to such characteristics as elemental composition, charge, shape, Crystallinity, surface area, solubility and surface chemistry/ derivatization. [1][2][3][4][5][6] Understanding the nano particle-cell interaction is thought to be critical for the safe development of nano materials. 7 It seems unlikely that the potential toxicity of nanoparticles and the underlying mechanisms can be predicted or explained by any single unifying concept.This review is focused on Titania (TiO 2 ) for which there is substantial interest in the chemical, biological, and industrial worlds because of its fascinating and useful physicochemical properties. Currently, information describing the relative health and environmental risks associated with nano-TiO 2 is severely lacking. Only recently, critical questions regarding the potential human health and environmental impact of nano-TiO 2 have been raised. [8][9][10][11] TiO 2 particles have long been considered to pose little risk to respiratory health because they are both chemically and thermally stable. 12 However, TiO 2 is classified as a Group 2B carcinogen by the International Agency for Research on Cancer (IARC) based on the findings of lung tumor induction in female rats. 13,14 Nano-TiO 2 is attractive for use in a large number of applications based on its unique optical and photo catalytic properties, tunable band gap, thermal stability, chemical resistance and hardness.15Because of the relatively large band-gap, the particles absorb the higher-energy (shorter wavelength) ultraviolet radiation making it a useful constituent in sunscreen products. TiO 2 photo catalysis is widely used in the fields of wastewater treatment, 16 sterilization, 17 self-cleaning, 18 hydrogen evolution, 19 and photoelectron chemical conversion. 20 Normally, TiO 2 can only be excited with ultraviolet (UV) light because of its wide band gap, 21 although this is considered a drawback when photo catalytic conversion is desired under visible light. The crystalline structure is the major factor determining the band gap, but secondary factors include the particle size and the presence of defects (physical or chemical). 22,23 A large surface-tomass ratio of the nanoparticles helps to promote catalytic reactions, and increases their ability to absorb and carry other compounds. Their surface reactivity originates from quantum phenomena that can make nano-TiO 2 seemingly unpredictable. 24Engineered nano-TiO 2 is designed to impart specific characteristics that vary according to their use. Aside from unique nanoscale properties (size, Crystallinity, reactivity, and thermodynamics), nanoTiO 2 may be funct...

“…Biomonitoring of trace elements is essential to assess ecosystem health (Duran et al, 2007;Yetimoglu et al, 2007). Metals can be categorized as: potentially toxic (Al-aluminium, As-arsenic, Cd-cadmium, Sb-antimony, Pb-lead, Hg-mercury) probably essential like Ni-nickel V-vanadium, Co-cobalt and essential like Cu-copper, Zn-zinc, Se-selenium etc.…”

In this study, concentrations of trace elements in tissues of shrimp species (Litopenaeus vannamei) from farming and zone natural coastal located in the northeastern Brazil were investigated. The elements determination was performed by optical emission spectrometry with inductively coupled plasma (ICP OES). The following ranges of concentrations in the tissues were obtained in µg g -1 dry weight: Al: 13. . The shrimp muscle can be a good iron source (about 88.9 mg -1 g dry weight). The distribution of Se concentration in tissues showed much variation between locations, and the concentration levels found in shrimp muscles of wild samples were high, where its levels in 67% of muscle and 50% of others tissues samples exceeded the ANVISA limit, indicating evidence of selenium bioaccumulation. Distribuição de elementos traço em tecidos do camarão Litopenaeus vannamei (Boone, 1931) da Bahia, Brasil ResumoEsse estudo teve como objetivo avaliar as concentrações de elementos traço em tecidos da espécie de camarão Litopenaeus vannamei coletadas da zona costeira e de carciniculturas localizadas no nordeste do Brasil. Os elementos químicos foram determinados por espectrômetro de emissão óptica com plasma indutivamente acoplado (ICP OES). Foram encontradas as seguintes faixas de concentrações desses elementos nos tecidos (em mg g -1 peso seco): Al: 13,4-886,5; Cd: 0, 80; Cu: 24, Fe: 3, Mn: 0,4; Se: 0,81 and Zn: 20,4. O músculo do camarão investigado pode ser uma boa fonte de ferro (cerca de 88.9 mg-1g peso seco). A distribuição da concentração de Se nos tecidos apresentou muita variação entre as localidades, com níveis acima do estabelecido pela ANVISA para 67% dos musculos e 50% dos outros tecidos investigados, indicando evidências de bioacumulação do selênio. Houve correlações significativas entre os seguintes pares de elementos:: Fe-Zn (r= -0,70), Mn-Cu (r= -0,74), Se-Cu (r= -0,68), Se-Mn (r= 0,82) nos músculos, Fe-Al (r= 0,99), Mn-Al e Mn-Fe (r= 0,62), Se-Al (r = 0,88), Se-Fe (r= 0,87), Se-Mn (r= 0,58) no exoesqueleto e Cu-Zn (r = 0,68), Al-Cu (r= 0,88), Fe-Cu (r= 0,95) and Fe-Al (r= 0,97) nas vísceras.Palavras-chave: Baia de Todos os Santos, camarão, elementos traço, bioacumulação, ICP OES.
