PPMIWerte
PPMIWerte refers to the "Parts Per Million" (PPM) values that indicate the concentration of a substance in a mixture. In environmental science and chemistry, PPM is a common unit for measuring very low concentrations of pollutants, contaminants, or other substances in air, water, or soil. It signifies how many parts of a substance are present for every million parts of the whole mixture. For example, a PPMIWerte of 10 for a pollutant in water means that there are 10 units of the pollutant for every 1,000,000 units of water.
These values are frequently used to establish environmental standards and guidelines. Regulatory bodies often set maximum
