I . Techniques for the preparation of a semi-synthetic basal diet suitable for the rapid production of zinc deficiency in the rat are described. The complete diet usually contains between 0.6 and 0.9 ppm Zn. 2. When the unsupplemented diet was fed to weanling rats, growth arrest occurred after 4-5 d ; when supplemented with ZnSO., to provide 12 or 20 ppm Zn, the rate of growth of rats was simil...

Kandungan logam berat pada sedimen sungai Batang Agam segmen Kota Bukittinggi telah diidentifikasi. Sampel diambil aliran sepanjang 3 km 6 titik sampel. Enam sampel yang kemudian di uji XRF untuk mengetahui kandungan beratnya. Hasil menunjukan bahwa mengandung Cr, Mn, Fe, Ni, Zn, Cu, As dan Pb. Konsentrasi rata-rata Sungai sudah melebihi ambang batas tetapkan, yaitu Cr (206,6 ppm), Mn (3646,6 F...

This study was conducted to prepare basic materials and offer advice regarding dietary habits to prevent and cure childhood obesity by comparing and analyzing dietary habit, nutritional status, blood factors, and mineral contents of hair. All subjects were stratified by their weight-length index (WLI). According to the standard WLI values, 64.9% of children were within the normal value, 13.5% o...

The effects of dietary selenium (Se), copper (Cu) and zinc (Zn) on growth characteristics, selected blood parameters and carcass traits in growing-finishing swine were evaluated in two experiments. In the first experiment, 48 Duroc barrows and gilts weighing approximately 30 kg were al lot ted by sex and weight to six dietary treatments. They were fed a basal 16% crude protein diet containing ....

The presence of high level of heavy metals involves a human healthy risk that could induce chronic diseases. This work reports on the metal contamination due to heaps of steel-slag accumulated during more than 40 years in allotments and industrial areas in the southern part of Madrid (Spain). Several slag and soil samples were collected in an area of 10 km(2) and characterized by different conv...

The present study estimated the concentration (in ppm) of heavy metals Zn, Fe, Cu and Pb in water samples edible tissue Labeo boga; both collected from non polluted (Station I) II) locations river Tawi, Jammu, India. mean (Zn, Cu, Pb) at Station I were 0.048±0.008 (ppm); 0.016±0.001 0.157±0.002 (ppm) 0.0001±0.0001 respectively; while II, these values 0.133±0.001 0.022±0.002 0.206±0.002 0.002±0....

The Red Dog Zn-Pb deposits are hosted in organic-rich mudstone and shale of the Mississippian Kuna Formation. A complex mineralization history is defined by four sphalerite types or stages: (1) early brown sphalerite, (2) yellow-brown sphalerite, (3) red-brown sphalerite, and (4) late tan sphalerite. Stages 2 and 3 constitute the main ore-forming event and are volumetrically the most important....
