Previous studies found that some metals could affect liver function. However, the effect of strontium (Sr) exposure on function has not been evaluated. A cross-sectional study involved 1021 residents from a mining area in Hunan Province, China. This was conducted to first investigate effects Sr alone as well combined with five other heavy metals, including lead (Pb), cadmium (Cd), manganese (Mn...

the concentrations of some heavy metals in sediment from the sinop coasts of the black sea were measured to monitor metal pollution in 2013. the distribution of the heavy metals in sediments of the black sea shows a variable pattern. the objectives of the present study were to elucidate the distribution heavy metals such as cu, pb, zn, ni, mn, fe, as, cd, cr, hg and co in sediment from sinop co...

This research examines traffic-source trace elements accumulations and distributions in roadside soils and wild grasses in the Qinghai-Tibet Plateau. A total of 100 soil samples and 100 grass samples including Achnatherum splendens, Anaphalis nepalensis, Artemisia sphaerocephala, Carex moorcroftii, Iris lacteal, Kobresia myosuroides, Oreosolen wattii, Oxytropis ochrocephala and Stellera chamaej...

metals concentrations in lumbricus terrestris and soil samples from the dumpsites located in zaria metropolis, nigeria were measured spectrophotometrically. mean metal content in dumpsite soils were: 25.95 - 75.17, 8.33 - 382.94, 124.84 - 206.96, 34.24 - 666.67 and 111.11 - 488.10mg/kg for cd, cu, mn, pb and zn respectively. while the concentration ranges recorded in l. terrestris samples were;...

Laboratory studies were conducted to determine the effects of different concentrations of Cu, Cd, Zn and mixture (equal concentrations from the three heavy metals) on growth and some oxidative stress (catalase and glutathione reductase) on Scenedesmus obliquus (microalgae) after exposure for 24, 48, and 96 h. In addition, the uptake of Cu, Cd and Zn were determined in the culture medium after 2...
