Harmful Effects:

•Some compounds of osmium areextremely dangerous. •They irritate the respiratory passage (throat, lungs,etc.), the skin, and the eyes.

Uses:

•Fountain pen nibs•Fingerprint detector•Phonograph needle

Osmium•From osme, or odor•Like Iridium, it is considered the most dense elements•It is a metal which has a pungent smell, and is used in producing alloys of extreme hardness

Harmful Effects:

•Compounds of rhodium stain the skin very strongly•It is very flammable•The substance can be absorbed into the body by inhalation of its aerosol

Rhodium•From Rhodon, or rose•This metal is lustrous and silvery white•It has a higher melting point and lower density than platinum•It has a high reflectance and is hard and durable•It is a very durable metal, insoluble in ordinary acids and very difficult to fuse

Uses:

•Headlight reflectors•Furnace windings•Spark plugs

Harmful Effects:

•Causes Copper PoisoningAcute ingestion of excessive copper can cause Diarrhea, Epigastric pain and discomfort, Blood in the urine, Liver damage, Low blood pressure, Nausea, Vomiting, Kidney failure due to severe intravascular haemolysis

Copper•From Cuprum, Cyprus•The metal used during the “bronze age”•The only red colored metal which is widely used in electrical products due to its high electrical conductivity

Uses:

•Cables •Wires•Gun metals

Harmful Effects:

•Chronic dust or fume exposure can irreversibly damage the lungs, producing shortness of breath and emphysema.•Cadmium mainly accumulates in the kidneys and liver and can lead to serious kidney failure, nephrotoxicity, renal stone formation, bone disease and persistent proteinuria at high exposures.

Cadmium•From kadmia or earth•It occurs in nature with Zinc•When heated, it burns with air with a bright light•Its compounds are toxic, particularly in soluble and respirable forms, being more easily absorbed through inhaled dust or fumes

Uses:

•Rechargeable Batteries•Solder•Electroplating

Harmful Effects:

•Mercury is ubiquitous in the environment. •Spewing from volcanoes, evaporating off bodies of water, and rising as gas from the Earth's crust, the poisonous, metallic element floats in the air as vapor or binds to particles. •Eventually it falls to the Earth to settle in sediment, oceans, and lakes, or reenters the atmosphere by evaporation.

Mercury

Uses:

•Thermometers•Paints•Pesticides

•From Mercury, the planet, HG from hydrargyrum, or liquid silver.•Is the only common metal which is liquid at room temperature•Mercury and the other noble metals were the first elements to be discovered and utilized by humans because they exist in nature either in the free state or as easily decomposable compounds.

Harmful Effects:

•Causes lead poisoning•Potential effects in humans are abdominal cramps, learning disabilities, attention deficit disorder, constipation, anemia, tiredness, nerve damage, vomiting, convulsions, anorexia, and brain damage. •Wildlife and waterfowl are also frequently poisoned through the ingestion of lead and lead shot. 

Lead

Uses:

•Batteries•Cable Covers•Drain Pipes

•Symbol Pb is from plumbum, the origin of plumber•A prehistoric metal which is durable but toxic•It has been the backbone of plumbing industries•Lead is a particularly dangerous chemical, as it can accumulate in individual organisms, but also in entire food chains

Harmful Effects:

•Exposure to inorganic arsenic can cause various health effects, such as irritation of the stomach and intestines, decreased production of red and white blood cells, skin changes and lung irritation. •A very high exposure to inorganic arsenic can cause infertility and miscarriages to women, and it can cause skin disturbances, declined resistance to infections, heart disruptions and brain damage with both men and women.

Arsenic

Uses:

•Poisons•Insecticides•Doping Agents

•From Arsenikos or male•It appears in three allotropic forms: yellow, black and grey; the stable form is a silver-gray, brittle crystalline solid•When heated, it rapidly oxidizes to arsenic trioxide, which has a garlic odor•A semi-metallic element noted or being poisonous although some of its compounds are medicinal

Harmful Effects:

•Excessive exposure to sulfur hexafluoride may affect the brain•The main impact of sulfur hexafluoride on the environment is a greenhouse gas, influencing climate change

Fluorine

Uses:

•Toothpaste Additive•Refrigerant•High-temperature Plastics

•From fluo, or flow.•It is a poisonous pale yellow element•Nearly all compounds are decomposed by fluorine forming fluorides that are among the most stable of all chemical compounds•It is the most reactive element known

Harmful Effects:

•Bromine is poisonous •Causes skin burns.

Bromine

Uses:

•Photographic Film•Gasoline Antiknock•Flame-proofing Agents

•From bromos, stench•It has similar chemical properties to Chlorine•At room temperature, bromine is liquid, giving off poisonous, suffocating, reddish vapor composed of diatomic molecules•It is used in industry to makeorganobromo compounds•A major one was dibromoethane an agent for leaded gasoline, before they were largely phased out due to environmental considerations

Harmful Effects:

•Some acute effects of tin are headaches, stomachaches and urination problem•Organic tin components can maintain in the environment for long periods of time•They are known to cause a great deal of harm to aquatic ecosystems, as they are very toxic to fungi, algae and phytoplankton•Organic tins are known to disturb growth, reproduction, enzymatic systems and feeding patterns of aquatic organisms

Tin•Sn from stannum •An ancient metal used in canning due to its resistance to rust and other corrosion•Tins as single atoms or molecules are not very toxic to any kind of organism, the toxic form is the organic form

Uses:

•Cans•Panel Lighting•Super Conductive Magnets
