Iodide concentrations in Saudi waters: A cause for concern.

Area of Science:

• Environmental Science
• Public Health Nutrition
• Analytical Chemistry

Background:

• Iodine is an essential micronutrient crucial for thyroid hormone synthesis.
• Iodine deficiency disorders (IDDs) remain a significant global public health concern.
• Assessing iodine content in water sources is vital for understanding dietary iodine intake.

Purpose of the Study:

• To quantify the iodide concentration in various tap water and bottled mineral water samples across Saudi Arabia.
• To evaluate the potential public health implications of observed iodide levels regarding iodine deficiency.

Main Methods:

• Water samples were collected from diverse regions within Saudi Arabia.
• Iodide concentrations in the water samples were determined using established analytical methods.

Main Results:

• All analyzed water samples, including tap and mineral water, exhibited low iodide concentrations.
• The findings suggest a potential widespread low iodine content in the Saudi Arabian environment.

Conclusions:

• The low iodide content in drinking water may contribute to insufficient iodine intake in the population.
• This could potentially lead to a higher prevalence of endemic goiter.
• Routine supplementation with iodized salt is recommended to mitigate the risk of iodine deficiency.
