Background and purpose
Lead (Pb) is used as a flux in the glazing process of pottery utensils in several regions of the world. It can affect the nervous and hematopoietic systems; in addition, it is classified as a probable human carcinogen. This work aims to evaluate Pb exposure of potters and describe the main determinants of elevated blood Pb (PbB) levels in this group of workers.
This is a cross-sectional study with potters of Maragogipinho Village, Bahia, Brazil, of both sexes, aged 16–72 years (n = 85). Non-exposed workers of the same age range residing in the urban area of Aratuípe town were also recruited (n = 50). We evaluated Pb dust deposition rates (PbDrt) in pottery workshops and PbB levels. All Pb measurements were performed by Graphite Furnace Atomic Absorption Spectrometry.
The median of PbB (min–max) and geometric mean (SD) PbDrt for the exposed group were 7.9 (0.9–49.8) µg/dL and 1463 (± 290,000) μg/m2/30 days, respectively. For the control group, levels were 1.5 (0.1–19.8) μg/dL and 82 (46) μg/m2 30 days, respectively.
The data found showed an excessive exposure among artisans, exceeding occupationally safe levels and those reported in the literature. It is important to implement occupational hygiene measures and improvements of the working conditions of these labors, especially the replacement of lead oxide in the pottery-glazing process.
