88 workers exposed to cadmium were examined at the 12 factories using or producing cadmium in order to know the present state of cadmium exposure and renal dysfunction in 1992. Cadmium in blood and in urine were measured and compared by the 3 exposure level of cadmium in air. Cadmium in blood of low, moderate and high exposure group were 2.5, 3,8 and 7.6 microgram/L, respectively. Cadmium in urine were 1.8(1.3), 3.8(2,6) and 7.9 microgram/L(6.1 microgram/g creatinine) , resrectively. However, there was no relationship between Urinary cadmium and beta(2)-microglobulin. Cumulative exposure estimate (CEE) was calculated by multiplying the mean ambient cadmium level of the factory and working duration. CEE has a high correlation with cadmium in blood and urine, but no relation to beta(2)-microglobulin. Because working durations were relatively shorter than European workers', the highest CEE was just 300 microgram. year/m(3), which was not enough to induce renal tubular dysfunction. This study, however, suggested the possibility that renal tubular dysfunction caused by cadmium could be happened in Korea in the near future.

The results of this study which had been investigated for the purpose of analyzing heavy metal concentrations in women's blood and urine, their correlation degree and significance of cadmium as indicator of accumulated heavy metals are as follows. 1) In blood, concentrations of Cd, Pb, Cu and Zn are respectively 0.0110+/-0.14 ug/ml, 0.208+/-138 ug/ml, 0.899+/-0.153 ug/ml and 5.432+/-1.020 ug/ml. 2) In urine, concentrations of Cd, Pb, Cu and Zn are respectively 0.003+/-0.12 ug/ml, 0.025+/-0.18 ug/ml, 0.013+/-0.12 ug/ml and 0.277+/-0.192 ug/ml. 3) Correlation coefficients between blood and urine are only significant in Zn (r=0.363, p<0.01). 4) In blood, correlation coefficients of Cd concentration and Pb, Zn are respectively 0.518 (p<0.01). 5) Correlation coefficients between Cd concentration in blood and Pb, Cu and Zn in urine are respectively r=-0.012, r=0.027, r=0.241 (p<0.05), and only Cd concentration and Zn is significant.

Lead (Pb) and cadmium (Cd) in milk were determined by atomic absorption spectrometry, using milk sample inorganication on sand-separated stove and sample inorganication equipment with graphit-Digi PREP Jr heat stabilization system. Results: sample inorganication equipment with heat stabilization system has the advantage of saving chemical and time. Atomic absorption spectrometry method and atomization technique in graphite furnace combined with Zeeman standardization technique allows determining Pb and Cd with limits of 0.0005 μg/ml and 0.005 μg/ml, respectively. This method has been used to check the quality of milk in general as well as to evaluate the effect of Pb and Cd contamination in epidemiology

BACKGROUND: Gejang (marinated crab) is a favorite traditional food and a main source of crab intake among Koreans. The present study aimed to identify the possibility of cadmium inflow to the body through gejang; accordingly, the relationship between gejang intake frequency and amount, and blood cadmium concentrations was investigated. METHODS: Using data from the first Korea National Health and Nutrition Examination Survey in the sixth period in 2013, means and standard errors of blood cadmium concentrations in relation to gejang intake frequency and amount, as well as the monthly intake of gejang, were obtained from 1381 participants for whom data regarding blood cadmium concentration measurements was available. RESULTS: After adjustment for confounding factors, a gejang intake frequency of four or fewer times per week and a monthly intake of 200 cm3 or less had no significant effect on blood cadmium concentrations. However, participants with gejang intake of at least five times per week had a weighted mean cadmium concentration of 2.12 μg/L (p < 0.001), and participants who had a gejang monthly intake of more than 200 cm3 had a weighted mean cadmium concentration of 1.76 μg/L (p < 0.001). CONCLUSION: These results suggest that to minimize the effect of gejang consumption on blood cadmium level, gejang intake should be limited to four or less times per week and 200 cm3 or less per month. Weekly intake of at least five times and monthly intake of more than 200 cm3 may increase blood cadmium levels.
