Heavy metals. Metals like mercury, zinc, copper, and cadmium usually enter the water supply as industrial waste and, in excessive concentrations, can cause physiological damage to humans, including damage to the central nervous system. Radium/Radon: Naturally occurring radioactive elements such as radium and radon have been linked to cancer in humans. Radon is found in gaseous form, and is absorbed through drinking, as well as through inhalation during washing or showering.
Heavy metals. As secondary batteries often use oxides from so-called xxxx- sition metals (cobalt, nickel, manga- nese), ashes and smoke in case of fire can be expected to contain powdery reaction products or residues, some of which are hazardous to health (cobalt) or toxic (nickel). An exposition to 25 mg of cobalt compounds may cause skin, lung and stomach diseases, damage to liver, heart, and kidneys as well as cancer in human beings. Inhaling nickel compounds increases the risk of devel- oping carcinoma in the lungs and the upper respiratory tract. Inflammable components: Some of the materials used in lithium batteries and of the individual battery compo- nents are combustible and highly in- flammable. Parameters which are im- portant for fire protection, such as flash point, ignition temperature, and com- bustion heat, point to a high fire load of the electrolyte materials used in lithium ion batteries. In most cases, the liquid electrolyte consists of inflammable or- ganic solvents and a conducting salt. Organic solvents used in lithium batter- ies are usually highly inflammable and capable of forming explosive mixtures with air. The conducting salt lithium hex- afluorophosphate (LiPF6): As com- pounds containing fluorine and/or phos- phorus (e.g. the conducting salt used in most cases: lithium hexafluorophos- phate (LiPF6)) are used in lithium bat- teries, unspecific gaseous substances may be released in case of fire; these toxic substances which are then con- tained in the smoke may constitute a serious hazard to people and the envi- ronment. These compounds are highly hygroscopic, so that the tiniest amount of water (if atmospheric moisture en- ters into a burst cell body, for example) may trigger chemical reactions which may result in the formation of hydro- fluoric acid (HF) and phosphoric acid (H3PO4). Phosphoric acid (H3PO4) is strongly hygroscopic and has an irritant or xxxxx- sive effect on the eyes, the respiratory tract, and the skin; if ingested, it causes damage to the gastro-intestinal tract. Hydrogen fluoride/hydrofluoric acid (HF) is a colorless gas (pungent odor, highly toxic, corrosive, and strongly hy- groscopic) and causes adverse health ef- fects already at the slightest concentra- tions (1.4 ppm) and serious or permanent damage (IDLH value: 30 ppm). In a reac- tion with water (e.g. fire extinguishing water), hydrofluoric acid (corrosive and irritant effect on mucous membranes and skin, risk of severe damage to eyes and lungs, disorders of meta...
