- Correlación de protoporfirina zinc y plomo en sangre en trabajadores de fábricas de baterías, de Bogotá, Colombia Omayda Cárdenas Marcela Eugenia Varona Sandra Marcela Núñez Jaime Eduardo Ortíz German E. Peña Salud Colombia blood lead inorganic lead occupational exposure Key words: protoporphyrin zinc Objective. To determine the usefulness of zinc protoporphyrinin blood (PPz) as an indicator of lead exposure inworkers of the homemade car battery industry. Materialand methods. A cross-sectional study was performed in116 workers of the car battery industry in Bogotá, Colombia.Data on general, occupational, and health variableswere collected by interview. Two categories of PPz valueswere established: Those below the cutoff value (70 mg/dL) and those above it. A linear regression analysis was performedto measure the correlation between logarithm valuesof PPz (>70 mg/dL) and lead in blood (PbB) (>38 mg/dL).Results. A semi-logarithmic correlation coefficient ofr=0.54 was found, and statistically significant associationsbetween high levels of PPz and direct exposure to leadwere observed (OR:3.35, 95% IC 1.02-11.91; p:0.02); forworkers who often use lead as a raw material (OR:7.80,95% IC 2.96-21.03; p<0.01), as well as for workers who donot change work clothes often (OR:3.55, 95% IC 1.17-11.01;p<0.01). Conclusions. PPz may be a useful diagnosticindicator for lead poisoning; it may also be used as a screeningtest for surveillance programs in the biological monitoringof workers exposed to lead.
