0.0001 ppm (parts per million) represents a very small concentration of a substance in a solution or mixture. Specifically, it means that for every million parts of the total, there are 0.0001 parts of the substance being measured. This is often used in environmental science and chemistry to quantify trace contaminants or substances in air, water, or soil. For example, 0.0001 ppm is equivalent to 0.1 micrograms of a substance in one liter of water.
