GAO WILL DETERMINE MOST EFFECTIVE '-'SI cF cancer research results for agencies
A study to determine bow research results on lie carc-r.cie.mcty of materials can be handled most effectively ta meet me needs of regulatory aienc.cs is being conducted by me General Accounting Office.
Research sponsorship and the government s coordinating activities for the screening of potential cancer-causing sub stances is earned out at the National Career Institute of the National Institutes of Health, but research is performed at many locations as implications for industrial. cr.Ytronrccatal. and other exposure! are ail dJferent.
The study by GAO was initiated internally, that Is. not at tie specific request of Congress Its purpose is to eiamine the problems in developing and recommending standards for screening possio.e carcinogens, and .ti scope includes cosu scheduling, and interagency information How, A CA' spokesman said that in addition to the National Carer Institute, research agenoes surveyed included the Nation! Institute for Occupational Safety and Health and the National Institute of Environmental Health Science!. Regulatory agencies studied included the Occupational Saf tv and Health Administration, the Environmental Protection

Other recommendations made in the report are as follows Based on the behavioral data and the relations,-, between PbB and ALA-D. a biomedical standard of 21 urn of .ALA-D was recommended.

NIOSH RECEIVES REPORT ON EFFECTS OF OCCUPATIONAL EXPOSURE TO LEAD
A biomedical standard for blood lead (PbB) of .07 milli grams of lead per. 100 milliliters of blood for workers was recommended in a report submitted to the National Institute for ^...jpational Safety and Health.
The report, entitled "Behavioral Effects on Occupational Exposure to Lead" was prepared under contract to .NIC2H by John D. Repko, Ben B. Morgan, Jr., and John Nicholson of the Performance Research Laboratory, Utuversity of Louisville, Louisville. Ky.
Five measures of body burden and 80 behavioral measures of task performance were obtained from 318 experimental and 112 control subjects. The experimental subjects were volunteers from among workers exposed to inorganic lead at their jobs in three storage battery manufacturing com panies. The controls were volunteers from five firms in volved in various types of light manufacturing.
The data obtained from the subjects indicate that PbB is not a sensitive measure of changes in functional perfor mance capacity. Aminolevulinic acid dehydrase in the blood (blood ALA-D) was found to be the most sensitive predictor of task performance.
relationship to decreases in ALA-D, but hearing levels at 500 and 1,000 Hz correlated positively with urine lead (PBU) and at 4,000 and 8,000 Hz hearing levels correlated positive ly with PbB.
Changes in watchkeeping, vigilance, and attentive as well as visual functions were not indicated by the data.
Biomedical Measure*
The study data suggest that PbB is "neither reliably stable nor sufficiently related to the effect of exposure to provace a sensitive measure of changes in functional capacity."
Blood ALA-D was found to be the strongest clinical measure of changes in the functional capacities assessed. The usefulness of ALA-D is based on two facts:
ALA-D is a quantitative measure cf the effect of lead on body biochemistry.
Inhibited ALA-D activity is detectable in the absence of urinary responses and at extremely low concentrations of PbB.
Intellectual Functions
The report noted that significant differences in intellectual functions between study groups or between PbB were not found in the experiment.
However, the report added, this should not be taken to mean that all intellectual functions are unaltered in ex

Because most industrial hygienists and government regulatory agencies employ PbB as an index of the extent of exposure, the report said, any specified changes in biomedical monitoring criteria must include this specific measure.
