Cadmium Fish are not normally cast out of pure cadmium, but if youre making a periodic table poster, why not? The hint of yellow is a bit of cadmium oxide, a favorite pigment of the impressionist painters, notably Monet.Breathing high levels of cadmium may severely damage the lungs and can cause death. Eating food or drinking water with very high levels severely irritates the stomach, causing vomiting and diarrhea. Cadmium mainlyaccumulates in the kidneys and liver and can lead to serious kidney failure
MERCURY Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver or hydrargyrum A heavy, silvery d-block element, mercury is the only metal that is liquid at standard conditions for temperature and pressureMercury has a number of effects on humans, that can all of them besimplified into the following main effects:- Disruption of the nervous system- Damage to brain functions- DNA damage and chromosomal damage- Negative reproductive effects, such as sperm damage, birth defectsand miscarriages- Allergic reactions, resulting in skin rashes, tiredness and headaches
Lead Lead pipes have been in use for thousands of years. In some cases the same pipe the whole time. This exotic six- way union was hand made by an apprentice decades ago, and it duly impressed the master. Exposure to lead and lead compounds can be toxic to humans andwildlife. Potential effects in humans are abdominal cramps, learningdisabilities, attention deficit disorder, constipation, anemia, tiredness, nerve damage, vomiting, convulsions, anorexia, and brain damage.
Cobalt Cobalt is used in pigments, notably cobalt blue, and in high-strength, high- temperature steel alloys. High purity cobalt is obtained by electrolyzing cobalt ions out of solution, resulting in bumpy plate like this.Cobalt inhalation can lead to ‘hard metal disease’, respiratory sensitization, pneumonia, wheezing, and asthma.
Beryllium This pure broken crystal of refined beryllium ordinarily would be melted down and turned into strong, lightweight parts for missiles and spacecraft. It is expensive and toxic, but unbeatable when cost is no object. CBD - berylliosis or chronic beryllium disease Primarily a lung disease, CBD may also affect other organs, such as thelymph nodes, skin, spleen, liver, kidneys, and heart. Short-term beryllium exposure may lead to inflammation, reddening or swelling of the lungs, a condition known as Acute Beryllium Disease. If beryllium enters cuts in the skin, non-cancerous ulcerating growths may form.
Helium Ordinarily a colorless, inert gas, helium glows pale peach when an electric current runs through it. A glass blower bent a tube to the shape of the letters He and filled it with pure helium. I lit it with high voltage.• excessive inhaling of helium is dangerous as it may cause death by asphyxiation within minutes• Helium is flammable
Uranium This is a chunk of depleted uranium metal, which is used in armor-piercing ammunition and counterweights. Only 20% less radioactive than natural uranium, it creates deadly hazards when used in anger.Because uranium is a radioactive substance health effects have been researched. Scientists have detected no harmful radiation effects ofnatural levels of uranium. However, chemical effects may occur afterthe uptake of large amounts of uranium and these can cause health effects such as kidney disease.
Chromium Many shiny things are chrome-plated; these chips show the result if you keep plating until a thick slab is built up. This process, called electrowinning, is how high-purity chromium is obtained from solution.Chromium VI - Breathing high levels of chromium (VI)can cause irritation to the nose, such as runny nose,nosebleeds, and ulcers and holes in the nasal septum.Ingesting large amounts of chromium (VI) can causestomach upsets and ulcers, convulsions, kidney andliver damage, and even death.
Plutonium This plutonium pacemaker battery case is empty--fortunately. If it were full, possession of it anywhere outside a body would be a crime. All no-longer- needed plutonium batteries must go home to Los Alamos. Plutonium may enter surface water from accidental releases anddisposal of radioactive wastes. Soil can become contaminated with plutonium through fallout during nuclear weapons testing. Plutonium moves slowly downwards in the soil, into the groundwater.
Arsenic Arsenic is a chemical element with a symbol As and atomic number 33. Arsenic occurs in many minerals, usually in conjution with sulfur and metals, and also as a pure elemental crystalArsenic poisoning is a medical condition caused by elevated levelsof arsenic in the body. The dominant basis of arsenic poisoning isfrom ground water that naturally contains high concentrations ofarsenic. A 2007 study found that over 137 million people in morethan 70 countries are probably affected by arsenic poisoning fromdrinking water.
