The Urine Specific Gravity diagnostic test is used to evaluate renal concentration ability for assessment of the urinary system. [17] Low concentration may indicate diabetes insipidus, while high concentration may indicate albuminuria or glycosuria. [17] Blood normally has a specific gravity of approximately 1.060. [18]
Heavy metals is a controversial and ambiguous term [2] for metallic elements with relatively high densities, atomic weights, or atomic numbers.The criteria used, and whether metalloids are included, vary depending on the author and context and has been argued should not be used.
The English name of the stone is derived from Middle French hématite pierre, which was taken from Latin lapis haematites c. the 15th century, which originated from Ancient Greek αἱματίτης λίθος (haimatitēs lithos, "blood-red stone"). Ochre is a clay that is colored by varying amounts of hematite, varying between 20% and 70%. [9]

[26] [27] [d] Some rarer metals are denser: tungsten and gold are both at 19.3 g/cm 3, and osmium—the densest metal known—has a density of 22.59 g/cm 3, almost twice that of lead. [28] Lead is a very soft metal with a Mohs hardness of 1.5; it can be scratched with a fingernail. [29] It is quite malleable and somewhat ductile.
Researchers analyzed 72 cocoa-based foods — including dark chocolate, often praised as a heart-healthy treat — over eight years. They found that 43% of the products contained an amount of lead ...
The Platinum Metals and their Alloys. New York: The International Nickel Company, Inc., 1941: 16. — "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T. Kirke. The Precious Metals, Comprising Gold, Silver and ...
