title: Correlation between cadmium and blood counts in workers exposed to urban stressor.
abstract: The objective of this study was to assess the exposures to cadmium (Cd) in urban workers and the association between Cd exposure and values of blood counts. Urinary Cd, blood Cd, and blood counts were obtained from 355 outdoor workers; a subgroup of 99 subjects were monitored to evaluate personal exposure to airborne Cd. The mean value of personal exposure to Cd was 1.5 ng/m3 for traffic assistants and 1.2 ng/m3 for drivers. Urinary and blood Cd were correlated to the airborne Cd (respectively r=3 and r=4). The multiple linear regression models showed the associations among white blood cell, the percentage of neutrophils (NEU%), the percentage of lymphocytes (LYM%), and the concentrations of blood Cd (respectively R2=27, R2=37, R2=581). The subjects with blood Cd values higher than 1.2 μg/L showed an increase of LYM% mean values and a decrease of NEU% mean values with respect to the group with blood Cd values lower than 1.1 μg/L.
