A recent proposal for controlling photochemical smog by the addition to ambient air of 0.03 to 0.05 part per million of diethylhydroxylamine (DEHA) is shown to be invalid. The addition of DEHA in the range of 0.05 to 0.5 part per million to ambient air irradiated with sunlight in a dual outdoor environmental chamber caused marked increases in the rates of formation and concentrations of ozone, peroxyacetyl nitrate, and light-scattering particles.
