Some parts are more likely to get infected or have problems. Piercings on your ear lobes usually take about 6-8 weeks to heal. However, piercings on the side of your ear (cartilage) can take anywhere from 4 months to 1 year to heal.
Ammonia is a colorless inorganic compound of nitrogen and hydrogen with the formula NH3, usually in gaseous form with a characteristic pungent odor. Ammonia is irritating to the skin, eyes, nose, throat, and lungs. It is essential for many biological processes and has various industrial applications.
Free ammonia is a chemical compound of nitrogen and hydrogen with the formula NH3. Technically ammonia in water is called Ammonium hydroxide. In the aquarium hobby the term ammonia also refers to an ionized form called ammonium (NH4+).These are held in equilibrium in the water [Citation needed]. ' Total ammonia ' (TA) or 'Total ammonia nitrogen' (TAN) refers to the total concentration of both NH3 and NH4+ in the aquarium water.Where you have Ammonia, you will also have Ammonium. The ratio of one to the other varies on pH and water temperature.So it is important to know these two readings when measuring Ammonia in your tank to gauge how serious the Ammonia levels are. See the Links section for a Toxic Ammonia calculator. Here is a table showing the varying levels of ammonia against ammonium.he ratio of one to the other varies on pH and water temperature.
