Photodynamic Bioassay of Poly eye lie Atmospheric Pollutants

Abstract

A photodynamic bioassay which can be conducted on one mgm amounts of organic atmospheric particulates is described. The results of a pilot study on pollutants from several American cities indicate that the assay may provide a rapid, simple and economical biological index of potential carcinogenic hazard attributable to polycyclic compounds. The utility of the assay for this purpose is under further evaluation.
