Chlorine: biological information
Chlorine as chloride (Cl-) is essential for mammals and plants. Digestive juices in the stomache contain hydrochloric acid.
Levels in humans
|Human abundance by weight||1200000 ppb by weight|
|Human abundance by atoms||210000 atoms relative to C = 1000000|

You can use this form to calculate how much chlorine your body contains. Enter your weight in either kilograms or pounds and click the "Calculate" button. You must enter a number, not text! Elements for which there are no data will always give a value of zero for the weight, no matter what you put in the weight box.
Hazards and Risks
Hazards and risks associated with chlorine: chlorine gas is very toxic because of its strong oxidising nature. Even low concentrations of chlorine gas attack eyes, throats, and lungs with painful effects. Chloride is relatively harmless.
