Much of the site was still laced with dangerous, long-lasting, radioactive isotopes from the 1940s, strontium-90, which mimics calcium and builds up in bones when ingested, emits beta radiation.
In industry, dolomite is an important source for magnesium and calcium metals, and is used as a flux for metallurgy. A flux is a material that melts easily and can be used to remove impurities from metal ores or to make the slag produced by metal ore smelting more fluid so it can be disposed of more easily.

Through computed tomography (CT) images of the heart and other types of imaging, build-up of dangerous coronary plaques — which restrict the flow of blood to the heart — can be detected, even before a person develops symptoms of heart disease. Because of this, there is increasing interest in using these imaging techniques to screen for heart disease. According to a review published
23/3/2020· Explanation of the pathogenesis and treatment of autism spectrum disorders (ASD) is one of the most significant challenges for scientists today. It is believed that a major pathogenetic factor of this condition is epigenetic changes caused by environmental factors, including toxic metals (cadmium (Cd), lead (Pb), mercury (Hg), aluminium (Al), and arsenic (As)). The nervous system may also be
In 1972, PCB production plants existed in Austria, West Germany, France, the UK, Italy, Japan, Spain, the USSR and the US.  [ page needed ] In the early 1970s, Ward B. Stone of the New York State Department of Environmental Conservation (NYSDEC) first published his findings that PCBs were leaking from transformers and had contaminated the soil at the bottom of utility poles.
Also, cadmium is dangerous because it can be taken up through the alimentary tract; penetrate through placenta during pregnancy, and damage meranes and the DNA. Once in the human body, it may persist in the metabolism from 16 to 33 years, and is connected to numerous health problems that include renal damages and abnormal urinary excretion of proteins (Guerra et al. 2012 ).
In one study, 122 Italian women took horsetail dry extract or Osteosil calcium 270 mg twice daily (a horsetail/calcium coination used in Italy for osteoporosis and fractures). Both groups who took horsetail experienced improved bone density, however the study was poorly designed.

28/5/2014· There has been growing clinical evidence to show computed tomography (CT) coronary artery calcium scoring shows a close correlation with a person’s long-term risk for heart disease. This data convinced the American College of Cardiology (ACC) to include CT calcium scoring in its revised guidelines for prevention and cholesterol released last fall. In addition, the ACC highlighted the
A process for the removal and recovery of ammonia from liquid waste, characterized essentially by the following operations: reacting the liquid waste with pure carbon dioxide, or with a gaseous mixture rich in carbon dioxide, or with at least one carbonate, to give
Amino acid chelates consists of a metal ion comprising iron, zinc, manganese, magnesium, copper and calcium. We also offer chelated EDTA selenium and mixtures thereof. These chelates are mostly used in nutrients, food supplements and fertilizers. The

The “SEVESO” Directive deals specifically with the prevention and control of major industrial risks involving dangerous substances. Named after the 1976 accident at a chemical plant manufacturing pesticides and herbicides in Seveso, Italy, it was amended several times over the years into a “SEVESO II”, then a “SEVESO III” directive, and its scope is progressively extending.

"The bronze surface would be coated with a mixture of ground gold—hence the name or moulu—and mercury, then heated over an open fire. While the gold adhered to the base metal, the mercury would evaporate, creating dangerous fumes.
The action violated the Geneva Protocol for prohibiting the use of poisonous gases in war, which Italy had ratified in 1925. The protocol came into force in 1928. Chemical weapons can be considered as stockpiled or non-stockpiled, observes Ron Manley, former director of the verifiion division of the Organisation for the Prohibition of Chemical Weapons.

If we consume too much calcium, without sufficient magnesium, the excess calcium is not utilized correctly and may actually become toxic, causing painful conditions in the body. Hypocalcemia is a prominent manifestation of magnesium deficiency in humans (Rude et al., 1976).
calcium carbide dropped into water. The exhaust is not vented, but stored in a reservoir, by changes in temperature, and not, as its name might suggest, solely by changes in atmospheric pressure. A flexible metal capsule is filled with an inert gas
Nitroglycerin (NG), also known as nitroglycerine, trinitroglycerin (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the …
Radium is an alkaline earth metal, just like calcium. Because elements in the same column undergo similar reactivity, the radium in the paint was shuttled to Mollie’s bones as if it were calcium. There, the radium decayed and emitted alpha particles directly to her bones and internal organs.
