Occupational Health Standard for Lead.
NIOSH 1976 Feb:179-184
Biological absorption for determining occupational health standards for lead (7439921) and biological monitoring for controlling lead in the environment are discussed, and the use of the threshold limit value and of air sampling for the above is disputed. Topics include are lead in blood and urine, urinary coproporphyrin (531146), urinary delta-aminolevulinic-acid (106605), particle size and absorption of lead, fluctuations in the airborne concentrations of lead in the work environment, exposure from ingestion and sampling errors in air monitoring. It is recommended that the biological limit value and OSHA compliance standard be a blood lead concentration of 80 micrograms per 100 grams of blood.
