Sodium fluoride is harmful to the body because when ingested it robs the body the ability to absorb calcium.
Sodium Hydroxide (NaOH) in solution is very strongly alkaline or basic. At even low concentrations it is dangerously corrosive to skin and eyes. Handle with caution, use gloves and eye protection, use the minimum amount necessary.
Na2S, also known as sodium sulfide, is a chemical compound that, when exposed to moist air, smells like rotten eggs. It not only causes skin burns, but it is toxic.

Fluoride is more poisonous than lead and just slightly less poisonous than arsenic. It is a cumulative poison that accumulates in bone over the years. Fluoride occasionally cause skin eruptions such as atopic dermatitis, eczema, or urticaria, gastric distress and headache. These hypersensitive reactions usually disappear promptly after discontinuation of the fluoride!
Because sodium soaks up water and if you digest to much you can die from a severe skin rash.
Sodium is eliminated from the body in sweat and in urine. So that would be the skin and the urethra to be exact.
In high concentrations, soluble fluoride salts aretoxic and skin or eye contact with high concentrations of many fluoride salts is dangerous. Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg/kg elemental fluoride/kg body weight) Ingestion of fluoride can produce gastrointestinal discomfort at doses at least 15 to 20 times lower (0.2-0.3 mg/kg) than lethal doses. Although helpful for dental health in low dosage, chronic exposure to fluoride in large amounts interferes with bone formation. In this way, the greatest examples of fluoride poisoning arises from fluoride-rich ground water.
An intact skin protects the body from infection, it helps to maintain body temperature, and to keep our skin protective against then harmful effect.
