Conmentt the aBore results show the- concentrations of respiratle load in air during the operation desorihed at the times the samples sere taken. It is
entirsly probable that eagles taksa of the Same operation in different rooms <*
or of the same operation in the seas roem at different tiimts would giro different results, from esperiaaoe In Sample taking, hoverer, so the sooond results would be of the ease order of magnitude as the first.
In our consideration of shat constitntes a dangerous exposure, e have too authoritative atatements. the report of the Committee on lead Poisoning of the American Public health Association (1930)1
H.................any condition wherein a worker may ingest or inhale & mg. or more of lead per day for SO days *....
or any workplace breathing atmosphere containing mors than S mg. of lead per 10 cubic meters, shall b# con sidered prime fade a condition of lead exposure, provided workers are employed 3 or more hours per day for a working period of SO or more days.*
