How are fumigant concentrations typically measured?

• A. Percent by volume
• B. PPM
• C. Grams per cubic meter
• D. Liters per second

Answer: (B)

Fumigant concentrations are most commonly expressed in parts per million (PPM), which is a unit that indicates the amount of substance in a million parts of air. This measurement is widely used in the context of gaseous concentrations, as it allows for a clear representation of small concentrations that are typical in fumigation processes. Using PPM helps to convey the level of exposure and efficacy of the fumigants in controlling pests. For example, if a fumigant is present at a concentration of 100 PPM, it means that for every million parts of air, there are 100 parts of that fumigant. This granularity is important in ensuring that the concentration remains effective for pest control while also being safe for the environment and people. Other measurements, such as percent by volume or grams per cubic meter, provide useful information in some contexts but may not be as practical for measuring the low concentrations commonly used in fumigation. Liters per second, on the other hand, is a unit of flow rate rather than concentration, making it less relevant to this specific question. Therefore, PPM is the standard and preferred unit of measurement for fumigant concentrations in fumigation practices.
