FIGURE 2.
Pesticide measurements captured by personal air monitors on Northern Thailand farmworkers (N = 51) with histograms showing distributions of detected values of (A) metalaxyl and (B) ethyl chlorpyrifos. aThe units of these measurements are ng/m3. Measurements below the limit of detection (LOD) have been removed from the histograms because they have falsified values due to calculations. Measurements below the LOD have been removed from the histograms and the values for the calculated ng of pesticide per cube meter of air (calculation: [(filter*2) / ((calibration of liters per minute) * minutes of spraying) (1/1000)])
