Measurements in aircrafts during application of biocides for aircraft disinsection
Abstract
Pest control operations in aircrafts are necessary to prevent the spreading of insect-transmitted infectious diseases. However, if pesticides are used in flight as sprays health disorders in passengers and crew members cannot be excluded. Measurements were taken during application of different disinsection sprays using the "top-of-descent" technique simulated at ground level in parked aircrafts. Concentrations in the air (during spraying and 40 minutes afterwards) were 21µg/m3/285 µg/m3 for pyrethrins/piperonyl butoxide (median values with SRA spray) and 133µg/m3 (224µg/m3) for d-phenothrin after use on Aircraft Disinsectant Denka ( Arrow Aircraft Disinsection Spray). Maximum amounts inhaled were calculated to be 17-200µg. Concentrations found on interior surfaces differed widely. On vertical surfaces (walls, folding tables, overhead bins) median values varied between <= 2 ng/cm2 and <= 17 ng/cm2 . Concentrations (median values) on seats, headrests and floor were 24-39 ng/cm² (pyrethrins), 144-233 ng/cm2 (piperonyl butoxide) and 219-1005 ng/cm2 (d-phenothrin).
