Eleven groups of inbred Wistar rats, five males and five females in each group, received graded doses of CdCl2, from 0-25 ppm, in the drinking water from conception until sacrifice at ten weeks of age. Litter-size, weight and water consumption were recorded at different ages of the animals. The Cd levels of indicators as blood, hair, incisors and molars, and target organs as femur, kidney cortex, liver, spleen, heart, gastrocnemius muscle and adrenal glands were recorded by atomic absorption spectrophotometry. Cd in the drinking water had no influence on number of animals in each litter, water consumption and growth of the animals. The results further confirmed that the primary target organs of Cd were the soft tissues, but that Cd can to some degree accumulate in teeth and bone, especially molars. The Cd content of all tissues, both indicators and targets, was positively and significantly correlated with dose. The positive significant correlation between the Cd levels of hair or molars, and every target organ suggests that hair and molars of rats are very useful indicators of a Cd exposure in progress. It is supposed that rodent molars are comparable to human deciduous teeth. It is thus suggested that human deciduous teeth and human hair can be used as an indicator of a Cd exposure in progress. |
