- Selenium is an
essential trace mineral for the human body, primarily because it acts as
an effective antioxidant preventing harmful cell damage.
- Selenium is a trace
mineral that is essential to good health but required only in small
amounts . Selenium is incorporated into proteins to make selenoproteins,
which are important antioxidant enzymes.
- Selenium (Se) is
both an essential nutrient as well as a toxic chemical. This dual
effect has been recognized for many naturally occurring chemicals.
Trace amounts are beneficial, while larger amounts are harmful. Of
course the toxicity of selenium depends greatly on the chemical form or
species
- Plant foods are the
major dietary sources of selenium in most countries throughout the
world. The content of selenium in food depends on the selenium content
of the soil where plants are grown or animals are raised
- Selenium compounds
may be used as an arming agent for antibodies, peptides, small
molecules, and nucleotides (e.g. aptamers). The selenium technology
attached to a targeting agent delivers a lethal payload to tumor cells,
pathogenic microbes, or other specific cells. Because of selenium’s
unique mode of action, selenium-armed agents have been shown to kill
bacteria at 4o C, indicating that there need not be metabolic activity
for selenium to be effective.
- Most recently,
scientists have discovered a way to accumulate highly bioavailable forms
of selenium in specially cultivated plants of the Crucifer family.
Plants in the crucifer family such as broccoli contain particular
antioxidants including sulforaphanes, isothiocyanates and indole
carbinols that have been linked to improved immune functions and are
widely sold as nutritional supplements.
- The rapid increase
in selenium
price is the result of large
purchases of selenium by
China in second half 2003, depleting refinery inventories. This high
demand continues and as spot supply dries up, purchasers are now
reportedly trying to locate supply under long term contracts with
refiners.
- Selenium enjoys a
wide range of usages that are expanding. Current usage of selenium is as
follows: Glass (25.7%), Metallurgy (23.9%), Chemicals (15.2%) , Pigments
(10.3%), Electronics (9.1%), Agriculture and Other (15.7%).
- Consumption is
estimated at 2,650 tonnes in 2003 and has been increasing at 1.6% per
annum over the period 1990 to 2000. Historically, the growth appears
steady; however, the recent market activity of China purchasing all
available selenium inventories suggests much larger growth rates in
China as its economy expands
at a very rapid rate .
- Growing uses of
selenium include: Selenium enriched fertilizers are now being used in
Finland, New Zealand, China and United States to get selenium into the
food chain and as an alternative to selenium addition directly to animal
feed. , Selenium additives to vitamin supplements, Selenium
treatments are being developed for a number of ailments including
dermatology, tendonitis, periodontal disease,
rheumatoid arthritis,
cancer, macular degeneration and cataracts, herpes and lupus
inflammation to name a few., Selenium is also being used in new
thin-screen technology in copper-indium-selenium solar cells
