Symptoms usually appear after a number of years, [5] but may rarely appear within a year. [6] Eye exposure to iron dust can also cause another form of siderosis, "ocular siderosis" or "siderosis bulbi", which can cause eye discoloration, but also eye damage, like cataracts and night blindness. This happens via the corrosive effects of iron. [7] [8]
Manifestation of iron poisoning may vary depending on the amount of iron ingested by the individual and is further classified by five stages based on timing of signs and symptoms. In mild to moderate cases, individuals may be asymptomatic or only experience mild gastrointestinal symptoms that resolve within six hours. [ 5 ]
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.Rust consists of hydrous iron(III) oxides (Fe 2 O 3 ·nH 2 O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3), and is typically associated with the corrosion of refined iron.
Signs and symptoms of selenosis include a garlic odor on the breath, gastrointestinal disorders, hair loss, sloughing of nails, fatigue, irritability, and neurological damage. Zinc toxicity has been seen to occur at ingestion of greater than 225 mg of zinc. [18] Excessive absorption of zinc can suppress copper and iron absorption.
As rust displaces a much higher volume than the originating mass of iron, its build-up can also cause failure by forcing apart adjacent components. It was the cause of the collapse of the Mianus River Bridge in 1983, when support bearings rusted internally and pushed one corner of the road slab off its support.
A recent study finds that 40% of young women and girls are deficient in iron, but their symptoms are often dismissed by some doctors. A ’startling’ number of young women and girls are ...
Oxide jacking has caused concrete spalling on walls of the Herbst Pavilion at Fort Mason Center in San Francisco. The expansive force of rusting, which may be called oxide jacking or rust burst, is a phenomenon that can cause damage to structures made of stone, masonry, concrete or ceramics, and reinforced with metal components.
