Plant nanotoxicology is an emerging and less-explored area of research for the plant stress biologists. The present study assesses the toxicity of bulk-CuO and nano-CuO (size <50 nm and surface area = 29 m 2 g -1) on maize ( Zea mays cv. hybrids triple white Hi Tech.) seedlings. Five successive...

The objective of the study is to determine accumulation and translocation of heavy metals from soil to paddy straw irrigated with urban sewage wastewater in peri-urban region of Girudhumal subbasin area in Madurai. The soil samples were collected in seven locations irrigated with treated and...

Natural diversity of intermittently closed and open lakes and lagoons (ICOLLs) depends on mutual interactions of several factors: (i) an impact of sea water and land background; (ii) temporary meteorological situation; (iii) hydrological conditions; and (iv) the shape of lake basin. However, some...

Ashes, formed as a result of combustion of biomass are a new class of by-products of combustion and due to the large variety of these materials their chemical composition has not been fully determined. Their use is limited, despite the fact that their production has increased. This work presents the...

Honey is one of the most valuable foods in terms of its antioxidant nature and antioxidant activity. In this study, their botanic origins, total flavonoid content, total phenol content, the hydrogen peroxide scavenging activity (HPSA) (in terms of SC50 (µg mL-1)), ferric reducing antioxidant power...

In Jordan and as in many other Mediterranean countries olive oil production is one of the major agricultural production, it is estimated that the annual production of olive oil in Jordan approximately 21.5 thousand tons per year. O the other hand the process of olive oil extraction generates around...

O the other hand the process of olive oil extraction generates around...

The objective of this study is to examine the ability of a compost material for removing {Cu}^{2+} from aqueous solutions with different parameters using continuous fixed-bed column. Compost was characterized by using Fourier transform infrared spectroscopy which revealed that the metal binding is...

Soil pollution was simulated by means of artificial heavy metal enrichment, in the presence of treated wastewater, and its effect on the growth characteristics of Beta vulgaris L. (red beets) i.e. on the dry matter yield, and on beet quality expressed in terms of dry matter heavy metal, nitrogen and...

Clay of the Middle Atlas Mountains region, Morocco, was used to investigate the removal of heavy metals ions (Cadmium and Copper) from aqueous solutions with respect to several experimental conditions including pH, contact time, initial solute concentrations, temperature and ionic strength. Kinetic...

In this study, chemical composition of coarse (PM2.5-10) and fine (PM2.5) aerosols and their seasonal characteristics was used to investigate factors affecting seasonal variations in concentrations of species. Concentrations of 17 trace elements and SO42- were determined in coarse and fine aerosol...

Herein, we describe the batch and fixed-bed column adsorption of Cu2+ and Pb2+ by raw and treated date palm leaves (DP) and orange peel (OP) waste biomass. Contact time, pH, adsorbent dose, and particle size were optimized in batch adsorption experiments, while breakthrough curves obtained in fixed...

In the present study, four beehive matrices (honey, propolis, pollen and bees), sampled from thirteen apiaries from Northern and Western Greece, were analyzed for the presence of Cr, Cu, Mn, Fe, Zn, Mg, and Ca. The proposed method involved microwave digestion with H2O2 and HNO3, dilution with water...

In this study, potential of okra leaves for the removal of Ni(II), Cu(II), Pb(II) and Cd(II) from the mixed metal aqueous solution were evaluated. The data were analyzed by Freundlich, Langmuir, D-R, Flory-Huggins and Halsey adsorption models. Pseudo first order rate, Pseudo second order rate...

The wastewater produced by the galvanoplasty industry is a serious environmental problem due to the high concentrations of heavy metals. In this study polymers were used in ionic flocculation to treat synthetic wastewater containing metals, applying four types of polyacrylamides with different ionic...

This paper present migration of some selected heavy metal (zinc, lead, copper, chromium and nickel) of roadside soil samples from along Ilesa-Akure highway with a view to assess the degree of contamination such soils contain and the likelihood that this contamination can be remobilized. Soil samples...
