Oh yes. The sea is teaming with iodine, and sea salt usually picks up some of this iodine. While it is not nearly as much as regular iodized table salt, there is still some.

According to my data Iodine is prestent in sea water at 0.00000015
PPM

There has to be more than that... in some places at least; because some species of molusk and seaweed rely heavily on the iodine present in water.

By the way YYYY, you've mentioned all this "data" (and I'm not saying I don't believe you, but I would appreciate a source, just so I can check it out myself.

Either way... it comes nowhere near the amount present in iodized rock salt.

Hi MB
Yes I would agree with that.

My data comes from my own document which is a compilation of many internet sources (so it's accuracy could well be called into question but it is all I have to work with till I can either verify it or scratch it). The PPM came from an assay of water used in the production of Celtic Sea Salt.

It is possible that these organisms have adapted to be very efficient harvesters of iodine or perhaps they don't need it in constant supply and are able to store it till needed. Or perhaps our assumption is incorrect and they simply accumulate it and have no mechanism to release it as waste?

Yes I agree.
How much iodine do we need?

But perhaps it depends on how the sea saly was produced?
Iodine 150 micrograms

People who eat fish should't have a problem with iodine. Should they?

I know one Australian Doctor is trying to get iodised salt indroduced into Tibet where Goitre is common.

Perhaps the best is iodised sea salt?

He shold be shot
The Tibeteans have their own very good source of land salt that they process through baking inside bamboo stems. They are doing just fine I think. If they listen to their holy men.

I think mother nature got it right.
We don't need to f**k with it

There is a saying "to much of a good thing"

In my opinion the balance of electrolytes in sea water is just right. Just ask any cetacean that lives in it.

Sea salt does contain traces of things that may not be good for you in larger quantities but the traces should have little affect. If one considers that the oceans are teaming with life that drinks this daily, the affects are probally minor, although there are those allergic to everything.

Salt, in any form, is good for you if your activities involve sweating. A little extra salt will cause the body to retain its water longer. That is why it was a form of currency in the Ancient Middle East. I remember a job during summer break between semesters in college. It was physically demanding in a hot environment. One of the old timers told me about the salt tablet dispenser near the lunch room. I took two aspirin sized salt tabs and found myself able to go hours longer before needing to hit the water hole.

A low tech method for desalinization of ocean water or muck water, is to begin with a tub of water covered in plastic, allowing some vapor space for evaporation. Next to the tub one digs a hole so one can use the cooler underground temperature as a low tech condenser, ie., hose to another jug perferably a thermal conductor to disappate the heat to the ground. Come back at night and one has water for the next day.

The salt concentration in the solar evaporator will have an impact on the rate of evaporation, where more salt will resist evaporation. In terms of the low tec water device, one should use fresh salt water each day or the water production rate will diminish as time goes on.

There is another low tech condenser design that would work in hot dry desert climites. This is based on the principle behind a cooling sack. This is an ancient technique for making cool water in the desert. The sack is composed of an animal skin that seeps water causing the outer surface of the sack to stay damp feeling. This seepage (sweat) will evaporate and absorb heat. The temperature of the water in the sack can drop 20-30 degrees F below the ambient air depending on humidity-evaporation. The cooling sack could be designed with a salt water outer shell, that will cool an interior compartment so it can be used as condenser.
