Spanish scientists say they've confirmed the presence of zinc, copper and lead at high levels in the Huelva estuary's water and sediments in southwest Spain. The team of researchers from the University of Cadiz also studied how some of the heavy metals are transferred to fish and discovered zinc, cadmium and copper accumulate in the body tissues of sole and gilthead bream. We found positive correlations between the levels of some metals in the waters of the Huelva estuary and those in the...

Because they are riddled with defects, bulk crystalline materials never achieve their ideal strength; nanocrystals, on the other hand, are so small there's no room for defects. ("Nano" is short for nanometer, a billionth of a meter.) Yet while nanocrystalline materials may approach ideal strength in their resistance to stress, most nanostructures have shown only a limited ability to withstand large internal strains before they fail. Overcoming this limitation could lead to great advances in...

Cadmium is a chemical element in the periodic table that has the symbol Cd and atomic number 48. A relatively rare, soft, bluish-white, toxic transition metal, cadmium occurs with zinc ores and is used largely in batteries. Notable characteristics Cadmium is a soft, malleable, ductile, bluish-white bivalent metal which can be easily cut with a knife. It is similar in many respects to zinc but lends itself to more complex compounds. The most common oxidation state of cadmium is +2,...

Silver is a chemical element in the periodic table that has the symbol Ag (from the traditional abbreviation from the Latin Argentum) and atomic number 47. A soft white lustrous transition metal, silver has the highest electrical and thermal conductivity of any metal and occurs in minerals and in free form. This metal is used in coins, jewelry, tableware, and photography. Notable characteristics Silver is a very ductile and malleable (slightly harder than gold) univalent coinage metal...

Zinc is a chemical element in the periodic table that has the symbol Zn and atomic number 30. Notable characteristics Zinc is a moderately reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen. The one common oxidation state of zinc is +2. Applications Zinc is the fourth most common metal in use, trailing only iron, aluminium, and copper in annual production. - Zinc is used to galvanize metals such as steel to...
