Organophosphorous compounds, which are used as insecticide and flame retardant, have delayed neurological toxicity and are suggested to be a cause of Chemical Sensitivity. In this study, the apparatus which can measure the emission amount of organophosphorous compounds in a real environment was developed. Emission amount can be known visually by enzyme inhibition reaction and color reaction. Detection by absorbance measurement is possible by 6-hour sampling, and visual judgment is possible by 24-hour sampling.
