Nitrate yog ib qho sib xyaw ua ke ntawm nitrogen thiab oxygen. Nws yog tsim thaum nitrogen los ntawm ammonia los yog lwm qhov chaw ua ke nrog oxygen hauv dej.

Nitrate ib txwm muaj nyob hauv cov nroj tsuag thiab hauv zaub thiab tuaj yeem pom hauv av, nyob ntawm seb muaj pes tsawg cov chiv thiab cov chiv siv rau hauv teb.

Raws li US Environmental Protection Agency, feem ntau cov neeg laus uas noj cov zaub mov zoo yuav noj 10 mus rau 25 milligrams nitrate lossis nitrogen ib hnub hauv lawv cov zaub mov. Feem ntau yog los ntawm nplooj zaub xws li lettuce, cabbage, celery thiab spinach tab sis kuj los ntawm cov nqaij kho xws li nqaij npuas kib.

Ntxiv rau nitrate los ntawm cov dej haus tsis huv yuav ua rau muaj kev phom sij loj rau kev noj qab haus huv. Tej zaum yuav ua rau tuag taus "blue baby syndrome" tau txuas nrog rau muaj nitrate hauv dej haus. Nws kuj tseem xav tias yuav ua rau cov kab mob thyroid, ntshav qab zib thiab qee yam mob qog noj ntshav.

Feem ntau qhov chaw ntawm nitrate muaj xws li nitrogen chiv, chiv, septic systems thiab dej phwj siv kev kho mob. Nitrate tuaj yeem nqa mus rau hauv dej hauv av los ntawm dej nag thiab cov daus daus uas percolates los ntawm cov av thiab bedrock mus rau hauv lub hauv paus aquifer.

Nitrate tseem tuaj yeem khiav tawm ntawm cov teb thiab ua rau cov dej tsis zoo, ua rau muaj kev cuam tshuam ntawm cov nroj tsuag hauv dej thiab cov algae, ua rau cov kab mob tsis zoo thiab qee zaus cov ntses tua.
