What is Iodine:
Iodine is a vital element for human health, serving as a fundamental component of thyroid hormones crucial for growth and development. Solid iodine presents as violet-black with a metallic luster and a distinct sharp odor. Naturally occurring in sea water and certain rocks, iodine is utilized in medicine as a topical disinfectant due to its anti-infective properties. It is also employed in microbiology laboratories for staining purposes. To address iodine deficiency, it is added to table salt to ensure an adequate intake in diets. Despite its benefits, iodine vapors are toxic and corrosive, and high concentrations can enhance the combustion of other substances.
Iodine Exposure and Health Risks:
While iodine is essential for health, exposure beyond certain limits can pose risks. Iodine can be harmful if swallowed, inhaled, or directly contacted. It acts as an irritant, particularly affecting the eyes and respiratory system. Concentrated iodine can cause skin irritation, burns, and rashes. Vapors of iodine are toxic, and repeated or prolonged exposure can lead to organ damage. Symptoms of inhalation include headaches, chest tightness, and lacrimation (tear discharge).
Regulations:
To safeguard workers from potential health risks, regulatory bodies have established exposure limits. The most recent exposure limits are summarized in the table below:
| Limit/Level | Type | Organization |
|---|---|---|
| 0.1 ppm | C (10 min) | OSHA |
| 0.1 ppm | C (10 min) | NIOSH |
