Accumulation and interrelationship of cadmium and zinc in human kidney cortex.

Cadmium and zinc have been analyzed in 102 normal human kidney cortex tissues collected from Indian hospitals. Cadmium and zinc were found to accumulate as age increased to 60 years, and had a log-normal distribution. Concentrations of cadmium and zinc in kidney cortex and cadmium/zinc ratios were comparable to those in other studies. The relationship between cadmium and zinc in kidney cortex gave a slope constant of 0.96 (YZn = 0.96XCd + 21.4).
