It is a rare blood condition in which the β-pyrrole ring of the hemoglobin molecule has the ability to bind irreversibly to any substance containing a sulfur atom. [ 1 ] [ 2 ] When hydrogen sulfide (H 2 S) (or sulfide ions ) and ferrous ions combine in the heme of hemoglobin, the blood is thus incapable of transporting oxygen to the tissues.
Sulfur dioxide is a mild but useful reducing agent. It is oxidized by halogens to give the sulfuryl halides, such as sulfuryl chloride: SO 2 + Cl 2 → SO 2 Cl 2. Sulfur dioxide is the oxidising agent in the Claus process, which is conducted on a large scale in oil refineries. Here, sulfur dioxide is reduced by hydrogen sulfide to give ...
Ionizing radiation may be used to treat other cancers, but this may, in some cases, induce a second form of cancer. [74] Radiation can cause cancer in most parts of the body, in all animals, and at any age, although radiation-induced solid tumors usually take 10–15 years, and can take up to 40 years, to become clinically manifest, and ...
“Skin cancer is the most common cancer in the U.S., and unprotected exposure to the sun’s harmful ultraviolet rays is a major risk factor for skin cancer,” the AAD stresses in its official ...
Arsenic poisoning (or arsenicosis) is a medical condition that occurs due to elevated levels of arsenic in the body. [4] If arsenic poisoning occurs over a brief period of time, symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. [1]
Skin cancer is the most common form of cancer, globally accounting for at least 40% of cancer cases. [5] [20] The most common type is nonmelanoma skin cancer, which occurs in at least 2–3 million people per year. [6] [21] This is a rough estimate; good statistics are not kept. [1]
Some 80% of sulfur mustard in contact with the skin evaporates, while 10% stays in the skin and 10% is absorbed and circulated in the blood. [ 3 ] The carcinogenic and mutagenic effects of exposure to mustard gas increase the risk of developing cancer later in life. [ 3 ]
