Estimation of Occupational Exposure to Phenoxy Acids (2,4-D and 2,4,5-T)

Occupational exposure to phenoxy acids (2,4-D and 2,4,5-T) has been studied in four men spraying 2% emulsion in kerosene from a tractor driven equipment. Air borne concentrations with stationary sampling point and from the individual breathing zone showed a mean 2,4-D and 2,4,5-T concentration of 0.1–0.2 mg/m3.
