<font color="red">

This is an abbreviation for "parts per million" and it also can be expressed as milligrams per liter (mg/L). This measurement is the mass of a chemical or contaminate per unit volume of water. Seeing ppm or mg/L on a lab report means the same thing...

Hope this helps u ✨ ✌

  • Explanation:
  • Parts per million (ppm) is the number of units of mass of a contaminant per million units of total mass. More: ppm (or ppmm) is used to measure the concentration of a contaminant in soils and sediments. In that case 1 ppm equals 1 mg of substance per kg of solid (mg/kg).
