Abstract Lead (Pb) is a toxic metal, frequently associated with occupational exposure, due to its widespread use in industry and several studies have shown high Pb levels in workers occupationally exposed to the metal. The aim of this study was to evaluate the influence of milk and dairy products (MDP) on Pb levels in blood (B-Pb), plasma (P-Pb), and urine (U-Pb), in workers from automotive battery industries in Brazil. The study included 237 male workers

information concerning diet and lifestyle were gathered through a questionnaire, and B-Pb, P-Pb, and U-Pb were determined by ICPMS. Mean B-Pb, P-Pb, and U-Pb were 21 +/- 12, 0.62 +/- 0.73 mu g/dL, and 39 +/- 47 mu g/g creatinine, respectively. Forty three percent of participants declared consuming <= 3 portions/week of MDP (classified as low-MDP intake), while 57% of individuals had >3portions/week of MDP (high-MDP intake). B-Pb and P-Pb were correlated with working time (r(s) = 0.21

r(s) = 0.20

p < 0.010). Multivariable linear regressions showed a significant influence of MDP intake on B-Pb (beta = -0.10

p = 0.012) and P-Pb (beta = -0.16

p < 0.010), while no significance was seen on U-Pb. Our results suggest that MDP consumption may modulate Pb levels in individuals highly exposed to the metal

these findings may be due to the Pb-Ca interactions, since the adverse effects of Pb are partially based on its interference with Ca metabolism and proper Ca supplementation may help to reduce the adverse health effects induced by Pb exposure.
