title: Integrated personal monitoring of cadmium exposure in Sweden.
abstract: Methods for the personal monitoring of human exposure to cadmium from air, food and beverages were studied in a group of 15 non-smoking women in Stockholm. Particles in the breathing zone air and duplicates of all food and beverages ingested were collected during seven consecutive days, as were faeces corresponding to the food ingested. Spot samples of blood and urine were also taken. The main sampling problems were caused by the noise of the personal air monitors and the short operation time of the batteries. On average, dietary cadmium (8.5 micrograms per day) contributed 99% of the total cadmium absorbed. There were large day-to-day variations in intake, most peaks corresponding to the consumption of seafood. Faecal cadmium was shown to reflect the total amount of cadmium ingested. There was a significant (p < 0.05) correlation between cadmium concentrations in blood (median 0.3 microgram/l) and average daily dietary intake of cadmium, but the blood cadmium levels could vary by a factor of four at one and the same average daily intake. The median urinary cadmium level was 0.2 microgram/l.
