Some diazoacetyl derivatives of glycine known as antitumor and immunosuppressive agents have been found to be powerful mutagens of the base substitution type.
متن کاملRelationship between Heavy Metal Concentrations in Soils and Grasses of Roadside Farmland in Nepal
Transportation activities can contribute to accumulation of heavy metals in roadside soil and grass, which could potentially compromise public health and the environment if the roadways cross farmland areas. Particularly, heavy metals may enter the food chain as a result of their uptake by roadside edible grasses. This research was conducted to investigate heavy metal (Cu, Zn, Cd, and Pb) conce...
متن کاملAssessment Of Elemental Concentrations Of Roadside Soils In Relation To Traffic Density In Calabar, Nigeria
This study employs Particle Induced X-ray Emission (PIXE) analytical technique for the analysis of elemental concentrations in the roadside soils in Calabar, Nigeria, in order to ascertain the levels of heavy metals in relation to traffic density. Twenty one elements, viz., Al, Si, P, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Rb, Sr, Zr, Nb and Pb with concentrations (in ppm), ranging f...
متن کاملAntimony in Urban Roadside Surface Soils: Concentration, Source and Mode of Occurrence
Antimony (Sb) is one of the elements of increasing environmental significance. In this study, concentrations of Sb were measured on 21 roadside topsoil samples collected from a medium-size city, Xuzhou (China), in order to assess the magnitude of contamination and to identify the possible contamination sources. The mode of occurrence of Sb and the effect of particle size fractions on Sb concent...
متن کاملMutagenic activity of concentrated drinking water samples.
Concentrated drinking water extracts prepared by adsorption onto XAD-2 resin have been tested for their ability to induce chromosome damage in mammalian cells. Extracts prepared from drinking waters derived from upland and lowland sources have been found to induce chromosome aberrations in Chinese hamster ovary (CHO) cells and human lymphocytes in vitro. Although the identity of the compounds r...
