Cadmium and zinc in human liver and kidney

Abstract

Liver and kidney samples obtained from 76 autopsies were analyzed for cadmium and zinc content. The patients had died of various internal diseases. None of them had any known occupational exposure to cadmium. A record was made of age, sex, place of residence, diagnosis, and smoking habits of each patient. The results showed no significant correlation between cadmium accumulation and hypertension or cardiovascular disease. There was, however, a significantly higher kidney cadmium level in smokers than in nonsmokers.
