Answer 1

Hint:Nitrate is an inorganic compound formed by the combination of nitrogen and ozone. It is an essential component for living beings but is harmful for infants if it is consumed in excess.

Complete step by step answer:Nitrate happens actually and at secure and solid levels in a few nourishments (e.g., spinach and carrots) and comes from normal forms, such as plant rot. Nitrate is in numerous fertilizers utilized on yards, golf courses, and crops. Other sources of nitrate incorporate release from sewage frameworks and creature squanders. The concern is with levels of nitrate over ten mg/L. Common sources may include fertilizer, septic systems, and animal waste.
High levels of nitrate can influence the amount of oxygen carried and can cause methemoglobinemia (too known as blue baby syndrome). Bottle-fed babies beneath six months are at the most noteworthy chance of getting methemoglobinemia. This ailment can cause skin to turn a pale blue color and can result in genuine sickness or passing. Other side months effects associated to methemoglobinemia incorporate diminished blood weight, expanded heart rate, cerebral pains, stomach issues, and heaving.
The U.S. Environmental Protection Agency (EPA) standard has notified that ten milligrams of nitrate per liter of drinking water (mg/L) is considered safe for everyone.

Note:To reduce or avoid such harmful effects it is advised to collect drinking water from a safe source, such as bottled water. It is very important for babies less than six months. Boiled water is not a safe alternative for purification as the boiling water will increase the concentration of nitrate.
