Inorganic substances commonly found in sewage sludge. The regulations include limitations on arsenic, cadmium, copper, lead, mercury, molybdenum, nickel, selenium and zinc.
metals include elements with a metallic luster and are found on and beneath the earth's surface, such as iron, manganese, lead, cadmium, zinc, nickel, gold and mercury.
Metals used in signmaking include: aluminum,brass,cast iron,copper, gold,iridium, lead,magnesium,mild steel,muntz metal, nickel, pewter, platinum, silver, stainless steel, tin, titanium, weathering steel, zinc.
Elements such as mercury, lead, zinc, nickel and cadmium that are of environmental concern because they can accumulate in the food chain and, in high enough concentrations, can be hazardous to the environment and the public's health.
The classification of metals used in dental restoration; they contain varying amounts of gold, palladium, and/or platinum. High noble contains 60% or more of gold, palladium, and/or platinum, with at least 40% gold. Noble contains 25% or more of gold, palladium and/or platinum. Predominantly base contains less than 25% gold, palladium and/or platinum.
A classification of possible contaminants such as mercury or lead.
(texiles) In combination with other fibres, gold, silver, copper and stainless steel can be used as a fibre in the form of thin strands. Imitation metallics can be manufactured by coating a plastic with a metallic finish. Conductive metal strands can be manufactured into rugs to eliminate static buildup.
A number of chemical elements that share certain special characteristics. Many metals can be toxic in high doses and can bioaccumulate in the food chain. Metals sometimes found at hazardous waste sites include: arsenic, barium, cadmium, chromium, copper, lead, mercury, nickel, silver, and zinc.
Metals, such as aluminum and copper are used to conduct the electricity throughout the microprocessor. Gold is also used to connect the actual chip to its package.
Include total and dissolved metals such as aluminum, mercury, silver and zinc that occur naturally or come from human sources such as mercury from dental uses.
Referring to "heavy metals": metallic elements with high atomic weights; (e.g. mercury, chromium, cadmium, arsenic, and lead); can damage living things at low concentrations and tend to accumulate in the food chain.
