From: Estimation of daily cadmium intake from cadmium in blood or cadmium in urine
Linear correlation of Cd in blood and Cd in urine (as corrected for creatinine concentration) with Cd in daily diet; the 1991–1997 survey [11]. The line in the middle is a calculated regression line. The two curves on both sides show the 95 % upper and lower limits. Each dot (n = 30) represent one survey site. a Cadmium in blood (Cd-B) versus cadmium in daily diet (Cd-D). b Cadmium in urine as corrected for creatinine concentration (Cd-Ucr) versus cadmium in daily diet (Cd-D)
