Biomass catalytic fast pyrolysis is one of the most promising technologies for the production of renewable aromatics and olefins directly from solid biomass. In this study, catalytic pyrolysis experiments were carried out on biomass in a fluidized bed reactor using typical metal-loaded (Mg, K, Fe, Ga, and Ni) ZSM-5 zeolites as catalysts. The effects of catalysts on the product distribution and ...

Human cardio-respiratory diseases are strongly correlated to concentrations of atmospheric elements. Bioaccumulation of heavy metals is strictly monitored, because of its possible toxic effects. In this work, we utilized the EDX microanalysis in order to identify the potential heavy metal accumulation in the lung tissue.  To this aim, we enrolled 45 human lung biopsies: 15 non-small cell lung c...

one of the most important methods to investigate heavy metals as pollutants is more likely to use bio-monitors which can be applied as an appropriate index to express the quality of environment. in current study, in order to investigate the effects of dominant plants in the desired region and role of aquatic macrophytes in monitoring such elements as zinc (zn), lead (pb), copper (cu) and cadmiu...

This mini review summarises the progress in field of MOFs and their use biomedical applications, from early discovery conception, to more recent achievements including promising in vivo applications.

 In a complementary field study, the concentrations of some metals (Cu, Ag, Pb, Zn, Ni, Co, Mn, Fe, As, Cd, Cr, Mg and Ba) were measured in clam Solen dactylus, sediments and water collected at two stations (Park-e-Qadir, 56° 20/ E, 27° 11/ and Nakhl-e-Nakhoda, 56° 23/ E, 27° 10/ N) of Bandar Abbas coastal waters of the Persian Gulf in November 2008 and February 2009 showing different contamina...

Nanomaterials are used for numerous biomedical applications, but the selection of optimal properties for maximum delivery remains challenging. Thus, there is a significant interest in elucidating the nano-bio interactions underlying tissue accumulation. To date, researchers have relied on cell culture or animal models to study nano-bio interactions. However, cell cultures lack the complexity of...

metals bioaccumulation in five organs of cirrhinus  mrigala , labeo  rohita and catla catla captured from three industrial and sewage polluted downstream sites (shahdera = b, sunder = c and balloki = d) were compared with a non-industrial upstream site (siphon = a) during high (post monsoon) and low (winter) flow seasons of river ravi. mean concentrations of metals were significantly higher in ...

BACKGROUND The goal of our study was to evaluate the effects of different medicinal herbs rich in polyphenol (Lemon balm, Sage, St. John's wort and Small-flowered Willowherb) used as dietary supplements on bioaccumulation of some essential metals (Fe, Mn, Zn and Cu) in different chicken meats (liver, legs and breast). RESULTS In different type of chicken meats (liver, legs and breast) from ch...

The phytoremediation potentiality of Cyperus articulatus naturally growing in industrial wastewater was tested. Nine heavy metals were selected for this purpose; As, Cd, Cr, Cu, Fe, Hg, Mn, Ni and Pb. Metal concentrations were measured using the atomic absorption. The accumulation rates of the studied heavy metals showed considerable variations in the accumulation abilities according to the pla...
