“…One reason for the present lack of association may be the low and varying bioavailability of Cd from food items (Chan et al 2001;Lind et al 1995Lind et al , 1998 and/or the uncertainty in estimation of Cd intake. In Japan, with a higher dietary exposure and with rice contributing about 40% of the dietary Cd intake, a correlation has been seen Watanabe et al 2000).…”

We studied determinants of cadmium status and kidney function in nonsmoking men and women living on farms in southern Sweden. Median blood Cd (BCd) was 1.8 nmol/L (range, 0.38-18) and median urinary Cd (UCd) was 0.23 nmol/mmol creatinine (range, 0.065-0.99). The intake of Cd per kilogram body weight did not significantly differ between sexes and did not correlate with BCd or UCd, which may be explained by a low and varying bioavailibility of Cd from food items. However, when a subgroup of the study population, couples of never-smoking men and women, were compared, a lower intake per kilogram body weight was found in the women, but the women had a 1.8 times higher BCd and a 1.4 times higher UCd. The higher female BCd and UCd may be explained by higher absorption due to low iron status. BCd and UCd both increased with age and were higher in the ex-smokers, who had stopped smoking more than 5 years before the study, compared to never-smokers. The contribution of locally produced food to the total Cd intake was relatively low and varied. Males living in areas with low soil Cd had lower UCd than the others. However, Cd levels in kidneys from pigs, fed locally produced cereals, did not predict BCd or UCd in humans at the same farms. The kidney function parameter ss2-microglobulin-creatinine clearance was related to UCd, whereas urinary protein-HC, N-acetyl-ss-glucoseaminidase or albumin-creatinine clearance was not when age was accounted for. Hence, even at the low exposure levels in this study population, there was an indication of effect on biochemical markers of renal function.

“…Reports on cooking loss of toxic elements such as cadmium are scarce due to the low content and difficulty in analyzing. About 40% of cadmium intake originates in rice for the general Japanese population (Watanabe et al, 2000). According to the Ministry of Agriculture, Forestry and Fisheries of Japan (MAFF), Japanese people receive about 50% of cadmium from rice and its products (MAFF, 2002).…”

We have studied changes in cadmium concentration during the cooking of rice (Oryza sativa japonica) to estimate actual intake. Samples included highly contaminated rice. Cooking involved washing and soaking rice, then cooking it in an electric ricecooker. Cadmium concentration was determined using ICP-MS. Inorganic element concentrations of P, K, Mg, Ca, Mn, Zn, Fe, and Cu were mainly decreased by washing step. Cadmium concentration was only slightly decreased by cooking and less so than other inorganic elements. In cooking of polished rice, cadmium concentration in cooked rice was about 95% of that in raw rice on a dry basis.

“…The stored samples originate from four research activities. The first group of samples was collected in Japan as part of the nation-wide heavy-metal monitoring projects led by Prof. Ikeda [2][3][4][5][6] during the late 1970s up to the 1990s. Beginning in 1980s, samples were systematically collected in Japan and other Asian countries within the framework of a consistent sampling design in which participants donated blood, urine and duplicate 24-h food samples.…”

Environmental specimen banks are an essential part of the infrastructure of environmental sciences. They have various functions: (1) evaluation of governmental environmental policy-making and regulations; (2) a resource for animal health evaluation; (3) research tools to investigate time trends in ecosystems; (4) detection of newly emerging chemicals in the time trends; (5) validations of computer models for environmental phenomena; (6) source identification of contaminants; (7) a tool for food safety; (8) evaluation of genetic selection pressure due to environmental changes. In this review paper, we present a detailed description of the Kyoto University Human Specimen Bank (history, protocol and questionnaires) and provide brief outlines of other representative environmental specimen banks. We then review two illustrative cases in which environmental specimen banks have unveiled insidious contaminations of polybrominated diphenyl ethers and perfluorooctanoic acids. Finally, we give a perspective of new functions for environmental specimen banks in the next 20 years.Keywords Environmental specimen banks Á Food duplicate sample Á Human breast milk Á Human blood
