Table 3 Proportion of farms (%) with Volatile Organic Compounds (VOCs) concentrations below the limit of detection (LOD) or between the LOD and the limit of quantification (LOQ) in the farm (living room, stable and granary respectively)

From: Indoor exposure to particulate matter and volatile organic compounds in dwellings and workplaces and respiratory health in French farmers

  1. LOD limit of detection is the lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) with a stated confidence level (generally 99%)
  2. LOQ limit at which the difference between two distinct values of a substance can be reasonably discerned
