4.2

Most important symptoms/effects, acute and delayed

no data available


4.3

Indication of immediate medical attention and special treatment needed, if necessary

Absorption, Distribution and Excretion

Studies on hamsters indicate that about one-third of inhaled cobalt oxide is absorbed. Twenty-four hr after inhalation of 0.8 mg of cobalt oxide, 23% was recovered in the carcass, 3% in the lung, and 0.5% in the liver and kidney together. Of the inhaled amt, 60% of the CoO (cobaltous oxide) was recovered in the GI tract. Possibly the amt of cobalt recovered in the GI was cleared from the lung since GI excretion of parenterally admin cobalt is comparably low. On the other hand, studies on rats show that the pulmonary absorption of inhaled cobaltous oxide may be considerably less. Intratracheally instilled cobaltous oxide (1.5 ug) was retained in the lung for a relatively long period with a half-time of about 15 days. This indicates that the pulmonary absorption of cobalt oxide is a slow process.

Cobalt oxide CoO

OxygenOxygen is the chemical element with the symbol O and atomic number 8, meaning its nucleus has 8 protons.
Oxygen is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.
Dioxygen is used in cellular respiration and many major classes of organic molecules in living organisms contain oxygen, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone.
Oxygen was isolated by Michael Sendivogius before 1604, but it is commonly believed that the element was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774.

CobaltCobalt atom is a cobalt group element atom that has atomic number 27. It has a role as a micronutrient. It is a cobalt group element atom and a metal allergen.
Like nickel, cobalt is found in the Earth’s crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron.
The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.
Cobalt is a naturally occurring element found in rocks, soil, water, plants, and animals.
Cobalt is used to produce alloys used in the manufacture of aircraft engines, magnets, grinding and cutting tools, artificial hip and knee joints. Cobalt compounds are also used to color glass, ceramics and paints, and used as a drier for porcelain enamel and paints.
