Urinary delta aminolaevulinic acid and porphobilinogen in lead-exposed workers.
Of 100 workers exposed to lead in varying degrees, 34 had a urinary delta amino-laevulinic acid (ALA) concentration of above 0-6 mg./100 ml. and a further 35 had an ALA concentration of between 0 3 mg. and 0-6 mg./100 ml. In only 20 of the workers was the urinary porphobilinogen concentration above 0-1 mg./100 ml., two of these being above 0-2 mg./100 ml. No significant correlation was found be...

Urinary &-aminolaevulinic acid (ALA) is commonly estimated by the method of Mauzerall and Granick (I956). In that method porphobilinogen (PBG) and ALA are successively separated from the urine by ion exchange resins. A simplified procedure, omitting the initial separation of PBG, was investigated. Urine samples from 39 lead workers and controls were estimated for ALA by both the original proced...
متن کاملEffects of urinary volume on urinary concentrations of lead , 6 - aminolaevulinic acid , coproporphyrin , creatinine , and total solutes *
Urinary volume was related to urinary concentrations of lead, delta-aminolaevulinic acid (ALA), coproporphyrin (COPRO), creatinine, and total solutes in nine lead workers. On a log scale, linear relationships were found between urinary volume and the urinary concentrations. There was a certain difference in the extent of the effects of urinary volume on the urinary concentrations. For example, ...
