Do you know what part of the hotly is affected by lead fumes? By ozone? By hydrogen sulfide? Or by the dozens of other common pollutants from industrial processes? Turn the page to a handy chart of specific body areas that are harmed by exposure to greater than maximum allow able concentrations of over 100 fumes, gases, solid particles from dozens
of basic industrial processes.
MAXIMUM ALLOWABLE CONCENTRATIONS
E A ollow ing m a x im u m a llo w a ble concentration values for continuous eight hour exposure are from 1958 issue of Industrial Ventilation published by American Conference of Governmental Industrial Hygienists. Substances are listed below for vour convenience in order given on following pages, by parts of body affected. M A C s given below are for breathing only, do not include skin contact.
