Lead Induced Ototoxicity and Neurotoxicity in Adult Guinea Pig
Figure 1
Lead concentrations of adult guinea pigs of groups A-E. As lead exposure time is prolonged, blood lead levels are raised and stabilized from day 15 forward, brainstem tissue lead concentration is raised and stabilized from 60th day on, and the lead concentration in the cochlear tissue began to rise at day 90.
