Airborne di-Butyl and di-(2-Ethylhexyl)-phthalate at Three New York City Air Sampling Stations

Abstract
Since some phthalate esters may be teratogenic, it is Important that ambient concentrations of these compounds should be established for proper medical evaluation. The 1975 yearly average concentrations of di-butyl phthalate at three air sampling stations in New York City (Queens, Brooklyn and Staten Island) were 3.73, 5.69 and 3.28 nanograms per cubic meter respectively. The yearly average concentrations of di(2-ethylhexyl)-phthalate for the same period at the corresponding stations were 10.20,16.79 and 14.20 nanograms per cubic meter respectively. The data were obtained by a G.C.-M.S. technique.
