Climate change and food safety: an emerging issue with special focus on Europe.
TLDR
The various food safety issues that are likely to be affected by changes in climate, particularly in Europe are identified. Expand
Trace metals in seagrass, algae and molluscs from an uncontaminated area in the Mediterranean.
TLDR
The concentrations of Cd, Cr, Cu, Pb and Zn were measured in specimens of four marine organisms selected as possible cosmopolitan biomonitors of trace metals in the Mediterranean area to gain a more complete picture of both the environmental conditions of the experimental area and the bioaccumulation patterns of the selected organisms. Expand
Oral, short-term exposure to titanium dioxide nanoparticles in Sprague-Dawley rat: focus on reproductive and endocrine systems and spleen
TLDR
In the spleen of treated animals TiO2 aggregates and increased white pulp were detected, even though Ti tissue levels remained low reflecting the low doses and the short exposure time, and prompted to comprehensively assess endocrine and reproductive effects in the safety evaluation of nanomaterials. Expand
Changes in selenium speciation associated with increasing tissue concentrations of selenium in wheat grain.
TLDR
The large predominance of selenomethionine in local wheat shows that local wheat can be a promising raw material for naturally enriched products to be used to supplement human and animal diets in low selenium areas. Expand
Human exposure to dietary inorganic arsenic and other arsenic species: State of knowledge, gaps and uncertainties.
TLDR
The analytical requirements for obtaining reliable data for iAs in food are discussed, and iAs levels in foods and beverages are summarized, along with information on other (potentially) toxic co-occurring organoarsenic compounds. Expand
Tissue distribution and acute toxicity of silver after single intravenous administration in mice: nano-specific and size-dependent effects
TLDR
It is concluded that if AgNPs become systemically available, they behave differently from ionic silver, exerting distinct and size-dependent effects, strictly related to the nanoparticulate form. Expand
Bioaccessible selenium in Italian agricultural soils: Comparison of the biogeochemical approach with a regression model based on geochemical and pedoclimatic variables.
TLDR
The model showed that within the range of concentrations measured in Italian soils, Se-bioaccessibility is controlled not only by the Se content of the soil parent rocks, but also by their overall geochemical nature and by pedoclimatic variables related to fluctuations of soil moisture and pH. Expand
An algal biosensor for the monitoring of water toxicity in estuarine environments.
TLDR
An algal biosensor for toxicity assessment of estuarine waters is proposed by coupling a suited algal bioreceptor to an amperometric gas diffusion electrode, which allows the monitoring of the evolution of photosynthetic O2 and the detection of alterations due to toxic effects caused by environmental pollutants present in the medium. Expand
Selenium bioaccessibility and speciation in biofortified Pleurotus mushrooms grown on selenium-rich agricultural residues.
TLDR
This study demonstrates the feasibility of producing selenium-biofortified edible mushrooms using seenium-rich agricultural by-products as growth substrates and the proposed approach can be used to evaluate whether se lenium-contaminated plant waste materials harvested from high-selenium areas may be usedto produce selenum-biotic mushrooms based on the concentration, bioaccessibility and speciation of Selenium in the mushrooms. Expand
Bioaccumulation potential of dietary arsenic, cadmium, lead, mercury, and selenium in organs and tissues of rainbow trout (Oncorhyncus mykiss) as a function of fish growth.
TLDR
It is shown that in farmed rainbow trout the ratio of mercury concentrations in feed and in fish is about 1:1, and rainbow trout does not approach the limits established for human consumption even when reared with feed at the maximum permitted levels. Expand
