WORTH A SECOND LOOK Our search for reviews for IUBMB Life includes essays appearing in media of more limited circulation that merit exposure to an international readership. One source of excellent reviews is the Australian Biochemist, the newsletter for the Australian Society for Biochemistry and Molecular Biology, Inc. A review on heavymetal detoxiŽ cation in plants was published there inDecem...

twenty water samples from a river system in southern caspian sea basin werecollected and analyzed for physicochemical parameters and metals (cu, zn, as, cd, pb, ni andmn). in order to evaluate the risk potential of metal pollution in river water, use of two indicesnamely heavy metal pollution index (hpi) and contamination index (cd) accompanied by clusteranalysis was taken in to consideration. ...

The rat mammary gland has a high content of ribonucleic acid during late pregnancy when the gland is functionally inactive (Greenbaum & Slater, 1957b). Slater (1956) suggested that this high level of ribonucleic acid might result from a very low activity of nucleic acid-degrading enzymes (ribonucleases) during late pregnancy. Rat mammary gland contains high concentrations of heavymetal ions, e....

ABSTRACT Physiological and structural alterations in broad beans (Vicia faba cv. Giza Blanka) in response to 10 M CuSO4, 10 M CdSO4 and a mixture of both solutions were recorded in 15and 25day-old plants. These treatments caused significant reductions in shoot height, leaflet area, fresh and dry weights, stomatal frequency, cell area in abaxial epidermis of leaflets, length and width of stomata...

Sound sources used for broadcasting on the air are usually produced and delivered in different levels of sound volume, thus inevitably creating the loudness/imbalance problem among various sound sources. This study examines the loudness of TV news anchorwomen’s voice and the sound of commercial advertisements on the Internet using Absolute Sound Level, to evaluate the current status and identif...

The aim of the present study is to evaluate the potential ecological risk and trend of soil heavymetal pollution around a coal gangue dump in Jilin Province (Northeast China). The concentrations of Cd, Pb, Cu, Cr and Zn were monitored by inductively coupled plasma mass spectrometry (ICP-MS). The potential ecological risk index method developed by Hakanson (1980) was employed to assess the poten...

vitamin B12. Therefore, the results of the study of Sirdah et al. Iron is themost abundant heavymetal in the earth’s crust and is required by almost all organisms.1 In the human body iron is required by and present in all cells and has several vital functions.2 Anemia due to iron deficiency is the commonest type of nutritional anemia worldwide, and occurs when body iron stores become inadequate...

this work reports the comparative study of heavy metal water concentrations fromtwo coastal ecosystems ofcadizgulf (swspain): bay of cadiz and ria ofhuelva estuary in samplestaken on years 1999-2000. sampling zones showed different heavymetal levels. statistical analysisof dissolved trace metal concentrations (cu, zn, cd and pb) showed significant differences betweenhuelva and cadiz zones based...
