Systemic Lupus Erythematosus affects several people around the world and because it is characterized as a chronic inflammatory disease of multifactorial origin, and with systemic impairment, great attention must be paid from diagnosis to treatment in

Lead migration from toys by anodic stripping voltammetry using a bismuth film electrode

Autor: Adriana M. Pimenta, Christelle S. Afonso, M. Renata S. Souto, Ana F. Q. Fernandes, Rita I. L. Catarino, M. Fernanda C. Leal

Publikováno v: Archives of Environmental & Occupational Health. 71:300-306

Metals may be released from toys via saliva during mouthing, via sweat during dermal contact, or via gastric and intestinal fluids after partial or whole ingestion. In this study, we determined the lead migration from toys bought on the Portuguese ma

In this work it was developed a novel application of bismuth film electrodes (BiFEs) for the determination of the antihypertensive and coronary vasodilator diltiazem by square wave cathodic voltammetry. The bismuth film was deposited ex situ on a gla

Effect of zeolites on cultures of the marine micro-algae Emiliania huxleyi

Autor: M. Fernanda C. Leal, Adriano Fachini, Arturo Garcia, J.L. López-Ruiz, M. Teresa S. D. Vasconcelos

Publikováno v: Aquacultural Engineering. 31:205-219

The yield of cultures of Emiliania huxleyi, a coccolithophore marine micro-alga species, in natural seawater and in seawater previously exposed to elutriates of ZEBEN-06 and ZESTEC-56, two zeolitic-nature products (ZNPs) (supernatant of 2.0 g l−1 o

Are zeolites capable of modifying the yield of marine micro-algae cultures? A case study with Emiliania huxleyi and a product of zeolitic nature

Autor: Adriano Fachini, M. Fernanda C. Leal, M. Teresa S. D. Vasconcelos

Publikováno v: Aquaculture. 237:407-419

Growth of the marine alga, Emiliania huxleyi , and chemical changes in the culture medium were assessed in response to the addition of differing concentrations of ZESTEC-56, a product of zeolitic nature (PZN). E. huxleyi was inoculated in natural sea

Comparison of the response of three microalgae species exposed to elutriates of estuarine sediments based on growth and chemical speciation

Autor: Ana P. Mucha, M. Fernanda C. Leal, M. Teresa S. D. Vasconcelos, Adriano A. Bordalo

Publikováno v: Environmental Toxicology and Chemistry. 22:576-585

The elutriate sediment toxicity test (ESTT) provides a measure of the amount of a substance that is exchanged between the sediment and the aqueous phase during resuspension processes such as floods or dredging operations. This study used ESTT with tw

Antagonistic interactions of Pb and Cd on Cu uptake, growth inhibition and chelator release in the marine algae Emiliania huxleyi

Autor: M. Teresa S. D. Vasconcelos, M. Fernanda C. Leal

Publikováno v: Marine Chemistry. 75:123-139

Some trace metals are known to act synergistically or antagonistically to influence phytoplankton growth limitation or toxicity. However, little is known about the effects of Pb and/or Cd on Cu uptake and liberation of exudates by marine micro-algae.

Seasonal variability in the kinetics of Cu, Pb, Cd and Hg accumulation by macroalgae

Autor: M. Fernanda C. Leal, M. Teresa S. D. Vasconcelos

Publikováno v: Marine Chemistry. 74:65-85

Here it is demonstrated that both Porphyra spp. and Enteromorpha spp. of macro-algae display similar and very marked seasonal variations in their concentration factor (CF) of Cu, Pb, Cd and Hg in field conditions. The CF variations are specific for e

Copper-induced release of complexing ligands similar to thiols by Emiliania huxleyi in seawater cultures

Autor: Constant M.G. van den Berg, M. Fernanda C. Leal, M. Teresa S. D. Vasconcelos

Publikováno v: Limnology and Oceanography. 44:1750-1762

Marine microalgae (Emiliania huxleyi) were grown in seawater enriched only with nitrogen and phosphorus, without control of free metal concentrations using synthetic chelators. Complexing ligands and thiol compounds were determined by cathodic stripp
