WebFor soil, 1 ppm = 1 mg/kg of contaminant in soil, and 1 ppb = 1 ug/kg. A measurement of 6 mg/kg is the same as 6 ppm or 6,000 ppb, which is equal to 6,000 ug/kg. Concentrations in Water Concentrations of chemicals in water are typically mea-sured in units of the mass of chemical (milligrams, mg or micrograms, ug) per volume of water (liter, L, l). WebTotal alkalinity is expressed as milligrams per liter (mg/L) or parts per million (ppm) of calcium carbonate (CaCO3). In the aquarium industry, total alkalinity may be referred to as "carbonate hardness" or "KH," which is often measured in degrees (dKH) rather mg/L or ppm. One dKH is equal to 17.9 mg/L or 17.9 ppm. WebFirst, it is a rear example of a carbon connected with a less electronegative element, silicon, which makes it shielded and therefore appear at lower ppm where other protons do not … tapper security biloxi ms
