TDS yog dab tsi?
Tag nrho cov txheej txheem yajywm raug xa mus rau tag nrho cov concentration ntawm cov tshuaj, nrog rau cov khoom xyaw uas tsis tov thiab cov organic teeb meem, muab pov rau hauv cov dej ntim uas tau muab, uas yog hais txog cov tshuaj mg rau ib lim los yog ib seem ntawm ib lab. Cov kab mob hauv cov dej uas muaj nyob hauv dej yog calcium, magnesium, potassium thiab sodium, uas yog tag nrho cov cations, thiab carbonates, nitrates, bicarbonates, chlorides thiab sulphates, uas yog tag nrho cov anions. Cations yog zoo them ions, whereas anions yog negatively them ions.
Cov zaub mov no yog los ntawm ntau qhov chaw, ob qho tib si ntawm natural and human activities. Qhov concentration thiab muaj pes tsawg leeg ntawm TDS nyob hauv cov dej ntuj yog txiav txim siab los ntawm geology ntawm lub qhov dej hauv qhov dej, cov nag poob hauv dej thiab cov dej sib luag. Kev hloov ntawm qhov sib xyaw ntawm cov khoom sib xws hauv cov dej mus tas li yog feem ntau ntawm cov dej ntws tawm, hloov mus rau dej (piv txwv li kev siv dej ntau los yog muaj nag lossis ntau dua) lossis los ntawm dej ntsev.
