Environmental toxins are linked to the rise in chronic and autoimmune diseases according to the National Institutes of Health (NIH). A pool without chemicals mitigates the threat of chemical toxins in one’s home and environment.
Some chemicals added to pool water never dissipate and will increase in concentration over time (copper, cyanuric acid, calcium are just a few examples). Pool owners have very little control over the chemical reactions and potential toxins resulting from the formation of by-products that occur when this happens. This may render chemicals that are intentionally added, to be less effective, resulting in the need for excessive chemical additions.
Used as an antiseptic. It is EPA registered as a pesticide. Known as a choke agent, inhalation of chlorine causes difficulty breathing. It is also linked to bladder and rectal cancer and heart disease.
Used as stabilizer. High levels render sanitizer ineffective to kill crypto parvum. It slows the rate that chlorine kills pathogens. Personal protection: p2 filter respirator for harmful particles.
If mishandled or improperly stored, calcium hypochlorite products can become unstable and dangerous, as is the case in general with chlorinating agents. Fire, explosion and/or evolution of toxic gasses could result.
Used to kill algae. It causes the algae cell to burst which destroys the plant. EPA rates it as a pesticide. Algaecides used in pools using copper may cause hair to turn blue or green. It will attach to you or your skin.
Contains polymers that act as coagulants on foreign particles suspended in the water. May cause chloramines which are toxic to humans. Nasty odor and side effects of burning eyes, itching and skin blotches.
