[at-l] Water filters vs. Tablets?

[ellen at clinic.net (Bob C)]

I don't know of any evidence that iodine properly used is harmful. But too much iodine can be. OSHA warnings say that:

"Chronic exposure to iodine may cause insomnia, conjunctivitis, inflammation of the nasal mucous, bronchitis, tremor, rapid heart beat, diarrhea and weight loss. Allergic sensitization may occur. Chronic iodine overdoses have produced iodism. Headache, fever, sneezing, salivation, and skin rashes may occur. 
Aggravation of Pre-existing Conditions: 
Persons with pre-existing skin disorders, eye problems, impaired respiratory function, or disease of the thyroid, lungs, or kidney may be more susceptible to the effects of the substance."
