What is the concentration measurement unit used for fumigants?

• A. Grams per liter
• B. PPM
• C. Milliliters per hour
• D. Percent by mass

Answer: (B)

The concentration measurement unit used for fumigants is commonly expressed in parts per million (PPM). This unit is particularly useful in the context of fumigation because it allows for precise measurement of the low concentrations at which fumigants are typically effective. PPM indicates the amount of fumigant present in a million parts of air or other mediums, making it a suitable unit for assessing the safety and effectiveness of the application in controlled environments. In the context of fumigation, it is crucial to maintain specific concentration levels to ensure adequate efficacy while minimizing risks to human health and the environment. Higher concentration units like grams per liter might not accurately reflect the potential exposure levels typically encountered, and volume flow rates like milliliters per hour do not convey the necessary information about concentration in an effective manner. Percent by mass can be useful in other chemical contexts, but PPM is the standard for evaluating fumigant exposure in the air. Thus, PPM provides a critical measure for those applying fumigants, ensuring both safety and effectiveness of the treatment.
